Red Hat 6 has been there a while, so what about certification with Oracle? Nothing on the Oracle support site, no press releases (maybe I missed one..). But Red Hat finally gave the answer in her Red Hat news - blog

This is the second post of my little project of building my own RAC on my Windows7-desktop (64-bits, 8GB RAM), using 3 VM’s (VM-workstation , 7.1.3 build-324285) : * 2 VM’s for two RAC-nodes, based on OEL 5.5, 11.2.0.2 for infra, and database. * 1 VM as my own SAN, based on Openfiler 2.3 (free), for ASM.

My RAC project with Openfiler, part I – Openfiler

My current job doesn’t offer me at the moment the opportunity to play with RAC or other stuff, so I decided to build my own RAC on my Windows7-desktop (64-bits, 8GB RAM), using 3 VM’s (VM-workstation , 7.1.3 build-324285) : * 2 VM’s for two RAC-nodes, based on OEL 5.5, 11.2.0.2 for infra, and database. * 1 VM as my own SAN, based on Openfiler 2.3, for ASM.

Unable to load module oracleasm with the ‘init’ command

While building my own RAC on two VM's, using a third VM with Openfiler on it as my SAN, I had to dowload, install, configure and load ASMLIB. Loading didn't seem to go smoothly at my own project. First I analyzed what I did, steps I took

iscsiadm discovery: no output with Openfiler.

By | December 31st, 2010|Categories: Database, RAC|Tags: , , |

I was building my own Oracle RAC 11g cluster (11.2.0.2) with Openfiler as my shared storage. Two VM's as my rac-cluster, one VM with Openfiler as my own SAN. Followed the instructions of the article of Jeffrey Hunter how to build a RAC on OEL and iSCSI, however this article is not based on VM. My Openfiler-VM was ready, given access to my both nodes on iSCSI-level, and now I want my rac1-node to discover the iSCSI-drives on my Openfiler.

Finished a RAC-course with instructor Harald van Breederode. Noticed that he used a script for setting up ssh on the nodes. Short, powerful.

Rewrite in Apache does not work anymore

Installed an Apache on Suse Linux 10. Configured httpd.conf including a rewrite rule in a virtual host. No configuration errors, but it did not work at all! After a while I discovered that the mod-rewrite module had been installed, but not enabled with this version of Apache (2.2.x).

While migrating discoverer sso-connections, ‘ssomig’ hangs

By | May 30th, 2010|Categories: App. Server|Tags: , , |

Helped a collegae who was migrating a discoverer configuration to another node with a different version (from 10.1.2 to 10.1.4) with now a 10.2 – infrastructure database in a separate home. The OID-users were already successfully migrated, with a little help of the example-script here, but one of the problems was that discoverer didn’t use the single-sign on. The other was that the private and public connection users had made, had disappeared.
