  • 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…

  • 11.1 GC agent refuses to start

    This is a follow-up post from my previous tale of how not to move networks for RAC. After having successfully restarted the cluster as described here in a previous post I went on to install a Grid Control 11.1 system. This was to be on Solaris 10 SPARC-why SPARC? Not my platform of choice when…

  • Troubleshooting ora.net1.network on an 8 node cluster

    It seems I am doing a lot of fixing broken stuff recently. So this time I have been asked to repair a broken 8 node RAC cluster on OEL 5.5 with Oracle RAC 11.2.0.2. The system has been moved into a different, more secure network, and its firewalls prevented all access to the machines except…

  • Oracle Support-final update to SR

    Just had a really pleasent exchange with Oracle support. I was after a way to purge the repository database of an OEM 11.1 Grid Control installation without having to blow it all away. Unfortunately, there is no such option. However, what I liked was this final update from the support member: Generic Note ———————— Martin,…

  • Getting up and running with Universal Connection Pool – Take 2

    In yesterday’s post (which is actually didn’t want to post that day) I wrote about the Universal Connection Pool feature. You should be able to get started with the information I gave you, but it didn’t include any hints on how to have a look under the covers of UCP. This can be changed …Oracle…

  • Getting up and running with Universal Connection Pool

    UPDATE 1 Martin Nash (@mpnsh) kindly pointed out a mistake on the ONS configuration in the resource element below. Thanks for that! UPDATE 2 This post was written for 11g Release 2 and Oracle Linux 5. Where applicable I have added information on how to do this with 12c Release 1 and Oracle Linux 7.2.…

  • 11.2.0.2 Bundled Patch 3 for Linux x86-64bit Take 2

    Yesterday I wrote about the application of Bundle Patch 3 to my 2 node RAC cluster. Unfortunately I have run into problems when applying the patches for the GRID_HOME. I promised a fix to the situation, and here it is. First of all I was unsure if I could apply the missing patches manually, but…

  • 11.2.0.2 Bundled Patch 3 for Linux x86-64bit

    It has become a habit recently to issue explicit warnings when presenting information that-if it doesn’t work as described-might cause you harm. So to follow suit, here’s mine: Warning! This is a Patch Set Update installation war story-it worked for me. That does by no means imply that the same works for you! So always…
