Re: FW: calibrate_io, Oracle Disk Manager and ORA-56719

thanks for looking up MOS, but as I stated I did that as well and none of the articles apply - we're neither on direct NFS nor ASM (doesn't seem sensible to me on a filesystem, anyway).

There are some more hints, though: Oracle 11.2.0.3 has changes in the ODM API that need a certain patchlevel for the VRTSodm package. It's not exactly my scenario but it will hit us anyway when going live with archive logging on. See:
http://www.symantec.com/business/support/index?page=content&id=TECH173597

I'll have the sysadmins install the latest patchset and then I'll try again.

Cheers,
Uwe
