Installing Oracle Linux 6 as a domU in Xen
Update: Please consider the context of the article-it was written in April 2011! The post refers to OpenSuSE 11.x, my current system uses OpenSusE 12.3 and the below problems of virt-manager appear to be solved. virt-manager however will perform similar steps as these under the covers. Introduction Despite all recent progress in other virtualisation technologies I…

They go by the title “Grid Intrastructure and Database High Availability Deep Dive”, and can be accessed via these links. Switzerland Austria To save you from having to get the abstract, I copied it from the Oracle…

Copying the password file for RAC databases
This post is inspired by a recent thread on the oracle-l mailing list. In post “11g RAC orapw file issue- RAC nodes not updated” the fact that the password file is local to the instance has been brought up. In fact, all users with the SYSOPER or SYSDBA role granted are stored in the password…

DBCA failing to create RAC databases
This is a weird problem I ran in today. As part of an automation project the code deploys RAC One databases across a cluster, depending on the capacity available of the node. These are 128G RAM BL685c G6 currently but will be upgraded to G7 later. Now, my problem was that after the weekend we…

Cluster callouts to create blackouts in EM
Finally I got around to providing a useful example for a cluster callout script. It is actually on the verge of taking too long-remember that scripts in the $GRID_HOME/racg/usrco/ directory should execute quickly. Before deploying this, you should definitely ensure that the script executes quickly enough-the “time” utility can help you with this. Nevertheless this…

Automatic log gathering for Grid Control 11.1
Still debugging the OMS problem (it occasionally hangs and has to be restarted) I wrote a small shell script to help me gather all required logs for Oracle support. These are the logs I need for the SR, Niall Litchfield has written a recent blog post about other useful log locations. The script is basic,…

Quis custodiet ipsos custodies-Nagios monitoring for Grid Control
I have a strange problem with my Grid Control 11.10.1.2 Management Server in a Solaris 10 zone. When restarted, the OMS will serve requests fine for about 2 to 4 hours and then “hang”. Checking the Admin Server console I can see that there are stuck threads. The same information is also recorded in the…

GC 11.1 and Monitoring Templates
Throughout the last 2 weeks I have been working (or better: tried to work) with Grid Control 11.1 as the central monitoring and deployment solution for my current project. The plan is to use EMGC 11.1 in conjunction with an 8 node cluster to automatically deploy RAC One Node databases. Please don’t ask about RAC…
