Why shouldn’t you write with a broken pencil?
Because it’s pointless!
And on that note, maybe read some of these blogs instead!!
Blogs of the week
Brendan Tierney explores some docker images and suggests building a Cloud environment here to create your own Spark environment to play and learn.
Y.V RaviKumar writes, “I have covered major steps here. Please refer for more details and pre-reqs https://mikedietrichde.com/2018/06/18/upgrade-oracle-12-2-0-1-to-oracle-database-18c-on-premises/ ”
John Keymer opens with, “Traditionally the development strategy for customisations within an organisation using Oracle E-Business Suite has been roughly the following.
- Data Entry – OA Framework or Oracle Forms
- Transactional Reporting – Oracle XMLP or Oracle Reports, FSG’s
- Ad/Hoc and Analytic – OBIEE or Discoverer
More and more organisations are now realising however the power of Oracle APEX to deliver all this and more within the low-code, highly capable framework. Beautiful, user-friendly, mobile-ready applications can be quickly delivered, fully integrated, secure, and scalable.”
He also advises his Best Practices blog.
Albert Rodriguez says, “With the emergence of so-called free and open source database software solutions, more and more companies are looking to break away from the grip of high cost database software. Just as quickly as management sees the dollar signs in savings, the Data architects and DBAs see the headaches brought about from making this change/move a reality.”
Jonathan Lewis writes, “Following on from the previous posting which raised the idea of faking a frequency histogram for a column group (extended stats), this is just a brief demonstration of how you can do this. It’s really only a minor variation of something I’ve published before, but it shows how you can use a query to generate a set of values for the histogram and it pulls in a detail about how Oracle generates and stores column group values.”
This blog opens by saying, “Today’s post will be about how ODI can be used to generate any kind of SQL statements using Oracle metadata tables. We always like to say that ODI is way more than just an ETL tool and that people needs to start to think about ODI as being a full development platform, where you may create any kind of code that you wish there. Today I’ll describe how we may create a simple (but dynamic) merge statement between two similar tables using an ODI procedure that will read from ALL_CONSTRAINTS, ALL_CONS_COLUMNS and ALL_TAB_COLS Oracle tables to figure out what to do.”
SLOB is an Oracle I/O workload generation tool kit, supports testing extreme REDO logging I/O (minimal amount of CPU overhead)

Laurent decided to write a new series of blog posts related to python programming language and its interactions with Oracle. He says, “This first blogpost will present how I use python on my laptop and how to install the required package to connect an Oracle Database.”
Ron says, “Prior to Oracle 12c moving non-ASM data files required taking data files ‘offline’ and negotiating an outage with the business, since Oracle 12c this is has no longer been the case. I was recently challenged with moving a good size filesystem 18c Oracle database from an existing storage platform to a new storage array.”
