I understood:
You can install as many RAC nodes as you need, OCFS will work fast. Correct?

We use SAP BIA (Business Intelligence Accelerator). There are 3 vendors, HP, Fujitsu/Siemens and IBM. IBM uses its own Fildsystem GPL, which seem to work good. HP and Fujitsu/Siemens are using OCFS and it is said both face the same problems.

BIA uses flat files. Possibly that could be the cause of the problems? Remark: OCFS Vers.1 was certified for Oracle Files only, OCFS2 should work with flat files also.

Has anyone some experiences with this? Received on Fri Feb 22 2008 - 01:09:48 CST
