Oracle Fusion Applications 11G: The new ERP era begins!

Oracle Fusion Applications 11G is now available! You can get the installation from the Oracle E-Delivery site in no time. This is the moment many of us have been waiting for, if not for many years then for many months for sure.

Oracle DBA: Huge Pages and Oracle Cluster 11GR2

In looking at this subject, most of you will say: Hey Yury! What’s new that you can tell us about? The following note describes it all:
11gR2 Grid Infrastructure Does not Use ULIMIT Setting Appropriately [ID 983715.1] These were exactly my thoughts when I was called to troubleshoot a case where a DB instance, starting with the “srvctl start instance” command failed to use Huge Pages in Linux.

11G R2 Cluster: AVOID using sqlplus & lsnrctl for Oracle

For last few months I was part of the Pythian’s team helping implement Oracle 11gR2 Clusters for different Oracle customers. All the implementations had different requirements and configurations, however, in all cases, the client’s DBAs made the same mistake over and over again. They used sqlplus and lsnrctl utilities to manage (start/stop) databases and listeners. This is totally wrong in the 11gR2 Cluster world.
