  • 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…

  • Presenting at Miracle Open World 2011

    Just a really quick post about my appearance at Miracle Open World 2011 in Denmark next month: http://www.mow2011.dk/ I strongly recommend you to have a look at the agenda and speakers, there are lots of fellow Oak Table members sharing their knowledge-quite an incredible lineup and a great honour for me to be there.

  • 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…

  • Using wget and proxy to download patches from MOS

    This is a rather quick note, but can be quite useful in certain situations. I currently look after a system which is quite difficult to jump on. That means before I get to do a “sudo su – oracle” I need to get to a jump-off box, ssh to 2 other machines and then log…

  • RAC One Node and Database Protection

    An email from fellow Oak Table Member James Morle about RAC One Node and failover got me thinking about the capabilities of the product. I have written about RAC One Node (RON) in earlier posts, but haven’t really explored what happens with session failover during a database relocation. Note this post is now showing it’s…

  • Error message of the day: OUI-25023 and the FQDN

    It’s been a long day with many problems around a Grid Control installation, including (but not limited to) corruption of the repository database, bugs in OUI when it comes to deinstalling the Oracle Management Server, lots of files left over by the weblogic “uninstall.sh” script and many more. Some of the error messages were quite…

  • Running Grid Control Agent commands standalone

    I had an error message today from one of my grid agents which was cut short in the GUI just when it became interesting. So I thought of a way of running the command on the comand line to get the full output. This has been a little easier than I thought. I based my…
