My recent post about adding space to ASM disk groups by resizing them larger, as opposed to adding more disks, did not show a Real Application Clusters example. Readers’ comments suggested there is concern amongst DBAs that resizing disks (larger) in a RAC environment might somehow be more difficult than in non-RAC environments. This blog entry shows that, no, it is not more difficult. If anything is true it is that adding disks to ASM (more...)

At times, I find it much simpler to shutdown my test database and create cold backup which will allow me to revert from any errors.
$ echo $ORACLE_SID
$ tar -cvzf /media/sf_OracleSoftware/$ORACLE_SID_$USER_`hostname -s`_backup.tar.gz .
$ ll /media/sf_OracleSoftware/DB01_oracle_arrow_backup.tar.gz

is doing a great job providing Docker Images for various Oracle WebLogic scenarios within the GitHub Repository https://github.com/oracle/docker-images/tree/master/OracleWebLogic
The provided samples are a real good starting point to create your Oracle WebLogic Servers and Domains including sample application.
But I personally miss one point within the Installation process of the Oracle WebLogic Server, applying Critical Patch Updates.
The integration is really simple.
As an example I will take Bruno's build file https://github. (more...)
When you have multiple Interactive Reports (IR) on your page and use a Region Display Selector to mimic tabs, you might notice some weird behaviour in the IR headings if you switch tabs. The headings are not positioned correctly and you get an extra empty row under the headings. It just looks weird and ugly. But if you resize your browser window, it all looks fine again (until you switch to another tab..)

few weeks back we had the opportunity to participante in an 12c
challenge which had lots of different flavours (BPM, Coherence, ADF,
etc.) and some very strict performance requirements.
this solution, an operator would be logged on to an ADF application
showing different regions, with one particular region that would update
as the BPM instance progressed through the different human tasks in the
process. The team had opted for a simple (more...)
We don’t often get a chance to share our customer success stories due to various reasons, such as required anonymity of the client or certain other legalities. But when we do, it sure feels great! Recently, Eurocontrol, a longtime Rittman Mead client in Brussels, Belgium, performed an upgrade of Oracle Data Integrator from 11g to 12c. With the help of Rittman Mead, and specifically data integration expert Jérôme Françoisse, Eurocontrol was able to (more...)
If you read our recent article Are Your Database or Java Skills Cloud Ready?, you may be wondering what the big deal is about exam 160 or how it can lead to so many different certifications.
I want to help clear the confusion.
Oracle Database Cloud Service | 1Z0-160 tests your Oracle Database Cloud Service skills, demonstrating your ability to administer your database in the Cloud. The resulting certification depends on your background.
Just what it sounds like – you ask to see LESS data in a grid, and we don’t re-query the database. Instead, we filter only on the client-side.
This means it’s FAST. No asking the database to run the query again.
This also means you might not be getting the WHOLE truth, or the latest truth. Unless... [Read More

Oracle NoSQL Database is an interesting option to consider when you want a schemaless, fast, scale-able database which can provide relaxed (eventual) consistency. Oracle provides a Node.js driver for this database. In this blog I’ll describe how to install Oracle NoSQL database and how to connect to it from a Node.js application.
The Node.js driver provided by Oracle is currently in preview version 3.3.7. It uses NoSQL client version 12. (more...)
