  • 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…

  • 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…
