Blogs of the week

  1. Intelligent Analytics in Data Visualization Desktop V4 (12.2.4.0.0)

Mike Hallett shares a link to download Data Visualisation Desktop (DVD), and also links to this video:

and the Youtube playlist.

There are also lots of links to reading material and documentation.

2. UKOUG Northern Technology Summit

This summit will take place in the North of England in early 2018 (April). Call for papers is now open.

3. OBIA 11g : Analyzing ODI ETL Load Performance – Part 1

Gunaranjan Vasireddy writes, “When you run an ODI ETL Load plan, it takes certain time. At times, customers would like to understand a split of the time taken by the load plan and analyze the top running maps to see if they can be optimized to run faster. In the first part in this series, we help you understand how you can easily analyze the time taken by the load plan and identify the top running maps.”

4. Essential WebLogic Tuning to Run on Docker and Avoid OOM

Andrejus Baranovskis advises us to read his previous post about how to run ADF on Docker firstly and foremost.  Then read on in this current blog to how to do the above.

5. Buffer cache hit ratio–blast from the past

Connor McDonald says, “I was perusing some old content during a hard drive “spring clean” the other day, and I found an old gem from way back in 2001.  A time when the database community were trying to dispel the myth that all database performance issues could be tracked back to,  and solved via, the database buffer cache hit ratio.  Thankfully, much of that folklore has now passed into the realm of fiction, but I remember at the time, as a means of showing how silly some of the claims were, I published a routine that would generate any buffer cache hit ratio you desired.  It just simply ran a query to burn through logical I/O’s (and burn a whole in your CPU!) until the required number of operations bumped up the buffer cache hit ratio to whatever number you liked Smile Less performance, more work done…. all to get a nice summary number…”

6. Using D3 and OBIEE

This blog opens by saying, “OBIEE is an integration of several pieces of technology that creates an enterprise grade scalable platform for delivering business analytics.  Because of the capabilities of OBIEE, people with no programming skills can create rich and complex visualizations using just the base functionality of the product.    When organizations do need special visualizations that can’t be accomplished with OBIEE’s delivered visualizations there can be a tendency to turn to other technology stacks because of the perception that either OBIEE isn’t easy to integrate or that using JavaScript libraries, like D3, within OBI will make it harder to upgrade the OBI in the future. ”

7. Problem loading java datasource OBIEE 12.2.1.3

Boris Dahav shares his experience of the above problem.

8. Using Content and Experience Cloud with your Oracle Intelligent Bots chatbot

Dolf Dijkstra says, “In this blog, I will show how you can use the content items from Content and Experience Cloud in your Oracle Intelligent Bots chatbot.”

He goes through:

  • Why?
  • Overview of the integration
  • Breakdown of the parts
  • Content type
  • Intent
  • Entity
  • DialogFlow
  • Custom Component
  • Service Module to construct query
  • REST call to the Delivery API
  • Re-using this sample

9. Go Big…

David Fitzjarrell concludes his ‘Go Big’ blog by saying, “Automatic Big Table Caching can be a performance improvement when large tables are the norm rather than the exception. That it’s also a feature that doesn’t require additional licensing makes it all the more desirable to configure and use.”

10. Comparing ODI Scenario versions using SQL

This blog starts off by saying, “The situation that I’m about to describe often happens in large/old ODI projects. Imagine the following: you received a task to change an ODI component that was created one year ago by someone else that is not even in the company anymore. The code is running fine in PROD and the business want a small fix to it. You open the ODI package and it contains a lot of interfaces, procedures, variables, etc. You need to change the code in one single interface, which seems very simple. You change it, save it, generate a new scenario and move it to PROD. When it gets there, the job fails due to an error in another interface that you did not touch! You start to troubleshoot and figure out that someone else changed something in DEV, saved it, but did not move the code to PROD. Unfortunately this ”unwanted” code change was included by you when you generated your scenario and now the mess is already created. If you already passed through this situation, than this post may help you.”

Good Oracle, Bad Project Manager

While Storm Brian batters the UK, Oracle batters us with update after Update!.

I am especially looking forward to Oracle XE 18.

It’s clear to me that the pace of Oracle change is picking up, and that we all need to embrace that change.  This month the DBA role was questioned with the introduction of the self updating database.  While some may be sceptical about the ability of Oracle to deliver a self maintaining database, if they do deliver then that could free up the DBA for more ‘productive’ activity, such as performance tuning everything, advising on database design and building framework PL/SQL (error traping etc).

This would help the OBIEE developers so they can focus on more content and less tuning activity.

Another thing that would help the OBIEE developer is to remove project management.  The biggest drain on a developer’s time are project managers who insist on pointless meetings, task updates, time estimates and thinking that their job is more important than everyone else’s.

It’s time that companies started trusting the developers more.  Let people know what the goal is, and let them get on with it.  You are only wasting your money and delaying your project by having a project manager.

10. ADF BC REST Service from ADF Library JAR

Andrejus Baranovskis writes, “I had assignment to enable ADF BC REST for existing ADF application, which was developed with multiple ADF libraries. ADF BC REST was supposed to be enabled for one of the ADF libraries and then accessed through Master application. All ADF BC REST samples usually show how to enable REST inside Master application itself. I was curious if it will work to enable ADF BC REST and package it into ADF library, which is consumed from Master application. It worked and I would like to share sample app.”

OBIEE Security – Layers

Applying security in OBIEE involves a myriad of controls that weave layers of protective barriers over the data.     

There are three Main layers, each with it own strata that work in isolation or in association with the other layers.

The main layers (from bottom to top) are:

  1. Database
  2. OBIEE Application
  3. Location

The Location layer is quite simple, it’s where you expose the web address and it’s how you decide who can see the web page.  For example, In a simple development environment you may have your server on a separate subnet, which is only accessible to developers using computers or virtual machines on that network.

Access to web servers can actually be restricted too, maybe behind a firewall, or to a specific set of IP addresses.  Windows Kerberos security can be employed to make sure you only allow access to the server from already authenticated people.

Dont forget the simple controls that the location of a server can bring, and please don’t expose your server to the internet directly (Or Christian will hunt you down!)

The Database layer has a wealth of security measures to protect the data.

A brief glance at the Oracle website, oracle /database /security, will show all the layers available in the database – similar options are available on MS SQL server too.

The simple measures not listed are also important to consider, for example the use of Separate Schema to separate your data.  You can keep HR records separate from Finance, separate from Sales etc, by placing the data into separate Users, or separate Pluggable databases even!  A common database security measure is Virtual private Database (VPD) which is worth examining, although I prefer to keep this sort of security in the application layer to keep it more flexible.

Data masking and data redaction can help to hide the real values, as well as database vault can keep the real data away from unauthorised users – like DBA’s!

The OBIEE Application layer has a mixture of Object Security and Data level security.

Object security is available in all three layers in the RPD and also available in the catalog.  The common theme is that the both use users and groups to determine what you can see.  The recent change to remove the very handy Catalog groups from the equation is a real shame, but at least Application Roles can do the job nicely, and could be sourced from corporate directories.

It’s worth pointing out that user roles use a hierarchy of permissions, or inheritance if you like.  This can get really confusing if Roles are members of other roles, which have conflicting permissions.  I prefer to keep a flat hierarchy of roles (i.e. no parent-child relationships) which makes my life simple.

Data level security is applied to the business layer of the RPD.  It magically adds a where clause to your queries, nicely hiding some data, and if you design it right, letting you see the big picture.

The trick with data level security is to secure only those dimensions that need securing.

You can also build your own fine grained security, just by making use of object security or just exposing subsets (using content levels or different views in the source).

 

In the next article in this series we will look into Object security in the Catalog..

Ric Van Dyke writes:  “With 12, Oracle introduced SQL Plan Directives, which in my view is really giving the optimizer a
chance to learn from its mistakes.   This is a step in the direction of a leaning optimizer.  In a way the optimizer is taking notes on how something ran and if not quite right, this note will help it not make the same mistake again.  It’s limited in 12.1 to just one type DYNAMIC_SAMPLINGand in 12.2 another one appears DYNAMIC_SAMPLING_RESULT.  Right now I’m going to focus on the first one.”

OBIEE is not dead, just has a new name

With just one more holiday to get through before back to work, there’s just enough time to catch up with the latest blogs we read this month.

Also happening this month were the speaker announcements for UKOUG, and unfortunately I didn’t make the cut. With so many submissions for a limited number of slots, I know it’s hard for them to decide, I have been there before on the Kscope selection panel, and there is always someone who is going to be disappointed – this time it was me.

I could speculate that it’s because my topic was not what they wanted this time, or because OBIEE is not their focus, or my submission was poor, or the sponsors took up lots of spaces, or the conference wanted more newbie speakers (or the same ones we normally see), or I annoyed the selection panel chair!  Unfortunately that’s all I can do – speculate.

So, how do I go forward from here?

In some ways it’s good to have been rejected, because the memberships fee, travel cost, hotel bill, loss of client billing, buying special equipment and software, all add up.  I was wondering why I was paying so much to give away my knowledge for free?

Then there’s the time saved, not having to work so hard to prepare the presentation.

But I guess the biggest benefit is that I reminded to constantly review the market and make sure I adapt to where it’s going  – no doubt that the Analytics  space is evolving and I need to evolve with it.  There isn’t even an Analytics track on Super Sunday – Just Apex, Database and fusion.

For the main event there is still an Analytics track, featuring Cloud (of course), Data warehousing (Good Old DW), Visualizations (New stuff) and what they call Advanced Analytics (Not sure which session this is).  There is little mention of last years trendy word (BIG DATA), and only a few mentions of data lakes, but we are still seeing lots of the Cloud word and Data Viz.  My biggest concern is there are only 2 (yes TWO) session that mention OBIEE.  Down on last year.

I still think the conference will be good, and worthwhile going if you can get your company to pay, but if I was going I think I would have trouble knowing which session to attend – the tracks conflict with each other, so I would find it difficult to decide whether to go to Apex, Database or Analytics sessions!

One speaker I would have liked to have seen is Daan Bakboord, and to quote his blurb

“Change is the law of life. And those who look only to the past or present are certain to miss the future.”

So I will take his advice and guess that in the future companies will still need Oracle Business Intelligence, some in the cloud, some cloudless, some with visualisations, some without, some advanced, some basic.  Oracle Business Intelligence will still need great database design, some customisations, and most importantly, will still need integrating into the client.  We may use new toys, new functions, new apps etc, but we will still be doing “Business Intelligence implementations”, and hopefully with great Oracle products, like OBIEE.

Hopefully all needing experts like me to be right on the cutting edge, and also fully up to speed with the current tech (i.e. OBIEE 11g/12c on site).

 

Anyway, start here, and learn!

7. Join Elimination Bug

Jonathan Lewis says, “A few years ago a bug relating to join elimination showed up in a comment to a post I’d done about the need to keep on testing and learining. The bug was visible in version 11.2.0.2 and, with a script to replay it, I’d found that it had disappeared by 11.2.0.4.Today I had a reason to rediscover the script, and decided to test it against 12.2.0.1 – and found that the bug was still present.”

8. Something Going Up Is Not Always Good

Stephen Few starts off by saying, “Even though our unique ability to deal with complexity propelled humans to the top of the evolutionary heap, we still crave simplistic (i.e., overly simple) explanations. I promote the value of simplicity in my work, but never simplicity that sacrifices truth. Simple things can and should be explained simply. Complex things can and should be explained as simply as possible, but never in a way that disregards or misrepresents their complexity.” Read on!

OBIEE 12c Security

Security of Data, Integrity of Systems and Ease of Use are fundamental cornerstones of any system,
-and OBIEE is no exception.

This is the first blog in a series which demonstrates security features and design choices that can made when building your secure Oracle Business Intelligence system.

In the series of blogs I will cover

  1. Data Security
  2. System Integrity
  3. Code Security

Data Security

The security of data covers a wider spectrum from Legal requirement (Data Protection Laws), to simple need to know rules.  On the one hand, the penalty for exposing data to the wrong people could result in serious consequences, while on the other you get to annoy your customers/users.  The severe consequences include legal cost and fines, major damage to your company reputation and the loss of customer revenue.  These all apply internally too, so just because your OBI project is only on the company intranet, dont be lax with the data.

Just to confirm, for Data Security we mean making sure we know the right people have access to the right data.  What they do with that data, e.g. downloading, emailing etc, is up to your company policies and controls, but for us we will focus on who can see what.

 

System Integrity

Anyone running an internet facing business knows just how many people are trying, on a daily basis, to break in.  Whether its kids, fraudsters or government agencies they all have the potential to take down your system.

For internal based systems you could think that the chance of people hacking into your code are reduced, this is up for debate, but the possibility is still there, and what if rival companies have sent in spies to work in your company!

The system intregrity blogs will cover Authentication as well and Authorisation as well as the protocols in place to safeguard access to the components.

 

Code Security

 

Finally I will cover my thoughts on code development and therefore security of code.  This is mainly to ensure that you can develop in a fast way, unincumbered by too much overhead, but still leaves your system code safe and reliable.

 

 

The next blog will cover the many layers of data security…

Summer Fun with OBIEE

I used to get earache on flights, but not any more
… this year I’m booking my kids five rows back

Why don’t mummies go on summer vacation?
They are afraid to relax and unwind!

The sun has got his hat on in Europe this week – time to head indoors, and enjoy the shade, with a cool drink and a computer full of OBIEE blogs!

Blogs of the week

1. Art of BI: OBIEE 12c Upgrade Gone Wrong? Bring in Datavail

Bill Anderson talks about when things go wrong. He says the aspects of OBIEE that can be adversely affected by an improper upgrade are:

  • Technical deployment
  • Infrastructure
  • Core Oracle Analytics
  • Security
  • Report Development
  • High availability sets

2. Trying out the Oracle Cloud Platform

Daan Bakboord links to the download page  and tells us to try out the Oracle Cloud Platform!

3. Enforcing Naming Standards for Your Data Models

Jeff Smith answers this question:

“We tried also to apply some naming conventions but I think we didn’t understand something….
Having a logical model with a table having the column X, and a glossary having the standard name as Y. Can I apply some checks based on the glossary directly in the logical or relational model?”

4. Extending Oracle DVD Map functionality

Irina Bakardzhieva goes through:

  • The Challenge
  • DVD 12.3 plugin
  • The ClearPeak’s Solution
  • Demo

5. SQLPLUS, login.sql and 12.2 in the cloud or not

Ric Van Dyke talks about a little hiccup in 12.2  with SQLPlus in this blog.

6. Sans Kscope

Scott Wesley talks about NOT going to KScope!

7. Multi-Instance Subprocess in Oracle Process Cloud Service

Antonis Antoniou says, “The May 2017 Oracle Process Cloud Service release on-boarded a very useful and powerful on-prem feature, that of multi-instance subprocesses. In a nutshell, multi-instance subprocesses allow you to execute a specific set of actions a specified number of times either in sequence or in parallel. What shouldn’t be confused is the difference between repetitions and multi-instances. Multi-instances will create a snapshot of a specific set of actions and data, and run it a specified number of times, with each instance living in it’s own private memory space.”

This week we have a great collection of updates – Including a great blog from Stephen Few, and some free stuff from Oracle.

We also see some more tips from the prolific Red Stack team – keep them coming guys!

I hope this week finds you on a beach, refreshing yourselves, and learning new stuff – I have just bought the latest books from Brendan Tierney, so look forward to getting sunburnt while loading more knowledge 🙂

Anyway, enjoy, wherever you are…

Blogs of the week

  1. Hunters Eat Better Than Gatherers

    Phil Goerdt discusses how we can better implement analytic solutions by challenging the convention of requirements gathering.

He says: Don’t “Gather Requirements”. Hunt for Questions.

“My take aways for consumers: Think about what data you need, the data you don’t have and what questions you can’t answer. From there, brainstorm how you can help the data suppliers understand these pain points. An export or data dump is a failing answer in my classroom!

My advice for suppliers: Try to read between the lines and understand what the consumers are really gunning for. Once you understand that, try to find ways to deliver it! “

2. Trial Subscription to Oracle Process Cloud Service

Antonis says, “Oracle has simplified the previously long and complicated process of subscribing to its Cloud Services, making it much simpler and quicker to get access to any of its Cloud Services.”

3. Basta, Big Data: It’s Time to Say Arrivederci

Stephen Few blogs about why he’s had enough of Big Data.

He concludes by saying, “Let’s say “goodbye” to the term Big Data. It doesn’t mean anything in particular and all of the many things that people have used it to mean merely refer to data. Do we really need a new term to promote the importance of evidence-based decision making?”

4. Oracle REST Data Services and Docker

Kris Rice goes through:

  • TL;DR
  • GitHub Project
  • The Build Structure
  • Optional Software
  • Running The Image
  • The build

5. Unpivot

Jonathan Lewis blogs about an interesting observation that appeared recently as a side-channel on a question on the OTN database forum – how does Oracle execute an unpivot()operation. He gives an example of such a query in this blog.

6. BI Publisher 12C: Running reports via the REST API

Paul Cannon writes, “BI Publisher 12c comes with a suite of REST APIs allowing you to manage and run reports via URL calls, primarily to allow you to make automated calls from custom applications. The APIs provide a wide range of functionality from creating reports & templates, updating definitions & xliff translation files to viewing the report definition & sample data, plus of course actually running the report.

In this blog I’ll go through the basics of viewing the report definition and running a report – providing parameters and downloading the report.”

7. What is Oracle Analytics Cloud and why should you care?

Christian Screen asks us to imagine that you don’t have to worry about hosting the necessary infrastructure in terms of servers, software, and storage space, and can concentrate on using the functionality and getting results in an environment that is:

  • Scalable
  • Flexible
  • Comprehensive
  • Secure

The Oracle Analytics Cloud is all the above and much more.

8. nl.OUG Tech Experience 15 June 2017

Daan Bakboord wrote of his experience at nl-OUG Tech Experience which took place in ‘De Rijtuigenloods’.

How to Update the ORDS_PUBLIC_USER Password

Jeff Smith writes, “ORDS_PUBLIC_USER is the database user that’s used to create your ORDS connection pool(s). Each database configured with ORDS gets one.

When you publish a RESTful Service under HR on database X, ORDS resolves the call to the proper jdbc connection pool, then proxy connects from ORDS_PUBLIC_USER to user HR, and runs the SQL or PL/SQL.

So, now imagine what happens when you let the ORDS_PUBLIC_USER password expire?” Read on for more…

10. Online Index Rebuild Problem in 12C

Neil Chandler blogs, “When building an index in Oracle Enterprise edition using the keyword “ONLINE”, if the index build fails for whatever reason a messy set of extents can get left behind.”

Data Visualisation Desktop and Data Visual Analyzer

This week we have a look at some DV blogs

If you would like to trial – and you should – then download free here:http://www.oracle.com/technetwork/middleware/oracle-data-visualization/index.html

By far the best way to learn DV is to watch the Data Viz Daily series from Kevin McGinley. Available on You Tube https://www.youtube.com

1. Adel Naser compares the Two products.

Oracle Data Visualisation Desktop Vs. OBIEE 12C Visual Analyzer

Adel Naser provides a comparison between Oracle Data Visualization Desktop (DVD), and Oracle Visual Analyzer (VA). He names some of the great qualities of DVD as:

  • Stunning rich interactive visuals, 22 visuals including geo mapping capability.
  • Easy to get started with the tool. Upload an excel file with the data to be analyzed and visualized, then start dragging and dropping columns to create your visuals.
  • Take snapshots of visualizations insights that are important to the business.
  • Integration between different data sources into one visual.
  • DVD is free for customers who have visual cloud solutions or an on premise version such as VA.

OBIEE, You’re soo cool

Auto-correct can be your own worst enema.

Charles Dickens walks into a bar and orders a Martini.
The Barman says: “Olive or Twist?”

Claustrophobic people are at their best when thinking outside the box.

Seriously, have a look out of the window. Its sunny, the economy is doing great, there are lots of OBIEE Jobs in the UK, and our friends at Peak Indicators won the Partner of the Year Award. Life is good. OBIEE is good. You are good at OBIEE (if you read our book)

Smile!

Blogs of the week

1.  Which version was it again?

Phil Goerdt writes, “Recently I had to verify the version of an OBIEE installation for a client. As I was already ssh-ed into the Linux machine, I figured there was a way to determine the version without having to log into the presentation server. Turns out I was right, but for thoroughness sake, I’ll cover both approaches.”

2. Oracle Management Cloud – Finding the needle in the haystack

Red Stack Tech blogs: “Director of Cloud Strategy, Philip Brown has recently written an article which has been published in the 2017’s first edition of Oracle Scene. In the article, he explores the Oracle Management Cloud Log Analytics service. Phil demonstrates how this service enables you to work across infrastructure and application tiers to provide a better understanding of errors and issues and turn the huge volumes of operational log data into a useful commodity.”

3. OBIEE 11g: Setting multiple values to Presentation variables through goURL and conditional filtering

Vishal says that he is writing this blog after a long gap and it is worth the wait!!

4. SQLcl – Setting Up the Formatter

Jeff Smith says, “Just because you’re in a command line interface doesn’t mean you’re stuck with ugly code!”

5. Getting Started with GoldenGate

Neil Chandler posts a link to his article in Oracle Scene

6. @Oracle 12.2.0.1 Cool new features to improve security. Part 1 Enhanced Whitelists PL/SQL

This blog states, “In Oracle 12.1 the ACCESSIBLE BY clause was introduced to the PL/SQL language. This gives the developer the ability mark a package, procedure, function, or type with what was allowed to call it. 12.2 gives us fine grained control over what can the specific functions and procedures in a package.”

7. Deception

Jonathan Lewis writes, “One of the difficulties with trouble-shooting is that’s it very easy to overlook, or forget to go hunting for, the little details that turn a puzzle into a simple problem.”

8. Integrating with Taleo Enterprise Edition using Integration Cloud Service (ICS)

Mani Krishnan says, “Integration Cloud Service (ICS) provides Oracle SaaS customers with pre-defined to connections to most SaaS subscriptions and zero-code integration features to quickly connect SaaS applications. Oracle Taleo provides talent management functions as Software as a service (SaaS). Taleo often needs to be integrated with other human resource systems.”

9. How Enterprise Manager Detects the Version of Oracle Databases

Gokhan Atil says, “You know that patch numbering has been changed since November 2015, and the new format replaces the numeric 5th digit of the bundle version with a release date in the form “YYMMDD”. Let’s say you applied PSU 160719 to your 11.2.0.4 database, the exact version of your database becomes 11.2.0.4.160799. We also know that PSUs do not change the Oracle release version information that can be queried from v$version (Doc ID 861152.1), so when you query your database, you still see 11.2.0.4.0”

He then goes on to elaborate on this.

10. Head in the Essbase Cloud No. 1 — The Blessed Event

Cameron Lackpour writes, “No, Yr. Hmbl., Fthl., & Obt. Svt. has not suddenly changed sex and really and truly had one of life’s miracles bestowed upon him but instead something almost as great has happened:  Essbase Cloud has launched.” !!

11. My query just got faster – brief introduction to 12.2 in-memory cursor duration temp tables

Keith Laker blogs, “This post covers one of the new SQL performance enhancements that we incorporated into Database 12c Release 2. All of these enhancements are completely automatic, i.e. transparent to the calling app/developer code/query. These features are enabled by default because who doesn’t want their queries running faster with zero code changes?
So in this post I am going to focus on the new In-Memory “cursor duration” temporary table feature. Let’s start by looking at cursor duration temp tables.”

12. How to find Oracle DVD log files

Dan Vlamis starts his blog by saying, “Hey, folks, I ran into a DVD error message that referenced a log and thought I would share where I found the log file in case others were wondering this.”

13. Presentations from OUGN17

Brendan Tierney shares some of his slides, including:

Catching Up with OBIEE News

My mate has been fired from his job at a dress alteration company.

Apparently he didn’t turn up enough.

OK, lets keep up the pace this year. Soo much to learn in the OBIEE world, so little time.

Lets talk about size. How big is your OBIEE? I was recently at an OBIEE presentation and the speaker talked about a ‘large’ obiee user base of 50 users. Sorry, but this is tiny, not even small. Should OBIEE really be used for less than 50 users? How about less than 100? Maybe, maybe not, but I do know it can handle millions of users. Seriously. MILLIONS.
Obviously not all at the same time, concurrent will be depending upon your BI Server hardware – You will obviously have to use Exadata for the database, but should you use a cluster? Well, you could. In fact most do, but whats best for a larger user base is ONE machine. Seriously, ONE.
One Exalytics machine, using as many of the processors as possible and you will have a simple environment that is fast enough for thousands of concurrent users. When you have more than 4,000 users per day, then forget the cluster, buy the Exalytics. If your client/company won’t buy Exalytics then they will spend more money trying to build and maintain the cluster of slower machines. You can go for cluster, and if you do, aim for one machine per 1000 daily users.

BTW Just how do you define concurrent users? Number of people logged in any any one time? Number of people logging in per hour? per day?. Is number of user relevent when some are running more queries than others? Is number of queries relevent when one person runs load intesive and 100 people run a quick query?

My Advice? Ask the users about their experience with the system. Use the Apex Survey app (You have installed that, right?) and monitor averages, Total Server time, Total database time, number of queires per 10 minutes, number of user logins, etc, etc. Develop a rich picture of server stats and make sure your users can let you know easily when the performance is unacceptable.

 

Anyway, read these.

now.

Heli writes: “I do not understand why there are configurations and templates related to reports in Data Modeler. What is the difference and when are they used?”

6. PL/SQL Security Coding Practices. Introduction to a better architecture part 1.

Robert Lockard says, “I have been seeing this database architecture for over thirty years and it’s high time we stopped using it. Before I go too far, let me tell you I get it, you have pressure to get the application out the door and working in a defined timeframe. I still design and develop systems and the pressure to take shortcuts can be great. This short cut is a security killer.”

7. Oracle Data Visualization Desktop Connecting to Essbase

Wayne D. Van Sluys talks us through how to do this.

8. Oracle 12cR2 – Howto setup Active DataGuard with Temporary Tablespace Groups

William Sescu blogs: “Temporary Tablespaces Groups exist for quite a while now (since 10gR2), but they are, for whatever reason not so often used. Personally, I think they are quite cool. Very easy to setup, and especially in big environments with a lot of parallel processing very useful. But this blog will not be about Temporary Tablespace Groups. They are already explained in the 12.2 Admin Guide.”

9. Best Practices – Data movement between Oracle Storage Cloud Service and HDFS

Ketan Rout writes, “Oracle Storage Cloud Service should be the central place for persisting raw data produced from another PaaS services and also the entry point for data that is uploaded from the customer’s data center. Big Data Cloud Service ( BDCS ) supports data transfers between Oracle Storage Cloud Service and HDFS. Both Hadoop and Oracle provides various tools and Oracle engineered solutions for the data movement. This document outlines various tools and describes the best practices to improve data transfer usability between Oracle Storage Cloud Service and HDFS.”

10. Loading Data into Oracle BI Cloud Service using BI Publisher Reports and REST Web Services

Dayne Carley says, “This post details a method of loading data that has been extracted from Oracle Business Intelligence Publisher (BIP) into the Oracle Business Intelligence Cloud Service (BICS). The BIP instance may either be Cloud-Based or On-Premise. It builds upon the A-Team post Extracting Data from Oracle Business Intelligence 12c Using the BI Publisher REST API.This post uses REST web services to extract data from an XML-formatted BIP report.”
