Mid November news

Although it’s only November, the shops are filled with Christmas items, the decorations are up in all the major towns and the shopping is in full swing. So, we obviously need a Christmas joke to go with the non-Christmas blogs this week.

What did Father Christmas say to his wife when he looked out of the window?
It looks like reindeer

Enjoy this week’s news, blogs and videos!

Blogs of the week

1. Getting Your Hands Dirty with TensorFlow 2.0 and Keras API

2. Oracle Datapatch – out of place patches simplified 

Martin Berger begins his blog with, “datapatch was introduced with Oracle 12.1 to simplify management of post-patching steps when a patch (or patchset) is applied. As most software, it was written with best intentions but little knowledge how customers would use it. One of these unforseen used case was parallel patching of multiple DBs in the same ORACLE_HOME at the same time. Another problem was missing rollback files due to out of place patching.”

3. Free Oracle Cloud: 15. The request could not be mapped to any database

Dimitri Gielis writes the last post in a series on the Best and Cheapest Oracle APEX hosting: Free Oracle Cloud.

4. Deprecated Functionality for WebLogic Server 12.2.1.4.0

Dirk Nachbar shares, “Since around 6 weeks the last Oracle WebLogic Server 12.2.1.4.0 Release is available and I got some spare time to read the necessary documentations. In the “What’s new Guide“, I found 2 interesting deprecated features, which weren’t announced somewhere else.”

5. RAC & Exadata // Some Tips & Tricks for the migration … for the performance

Erman Arslan quickly gives some tips and tricks that may be used before migrating a database environment.

6. How to use AWS S3 Bucket for Spark History Server

Gokhan Atil shares that since EMR Version 5.25, it’s possible to debug and monitor your Apache Spark jobs by logging directly into the off-cluster, persistent, Apache Spark History Server using the EMR Console.

He says, “You do not need to anything extra to enable it, and you can access the Spark history even after the cluster is terminated. The logs are available for active clusters and are retained for 30 days after the cluster is terminated.”

7. EPM Cloud – Integration Agent Part 7 – Drill down to source data

John Goodwin says, “It is time for the latest part of the EPM Cloud Integration Agent series, in which I am going to be looking at drill down functionality.

8. OAC – Clearing server cache

This blog begins with, “The support note (OAC -Oracle Managed – How To Perform Clear Cache of OAC Instance (Doc ID 2436095.1)) explains how to clear cache in OAC.”

There is also a link to this blog.

9. Aliases in Oracle in the cloud or not

Ric Van Dyke states, “After tuning hundreds of queries with thousands of lines in each of them, I really think that full table names are best.  Next best is shortening the name by removing non-leading vowels.   And even more important is make aliases unique within the statement.  This means if you use the same table more than once, put a 01, 02 and so on after each use.

10. Oracle DB Patching with EM 13.3

Alfredo Krieg Villa starts off his blog by writing,

“I got several interesting questions last week during my presentation about Oracle Enterprise Manager (EM) 13.3 and Exadata at the East Coast Oracle Conference 2019.

One of them was related on how to patch a DB home using EM 13.3 and I’ll try to show it on this post.”

He finishes his blog by saying, “Note that after the patches are successfully deployed, the Plan will be locked. Also, you have the option of creating a template of the Plan so you can deploy it to different targets later.”
