Cause
Unable to read the redo logs, issue related to cio mount option -
Resolution
For AIX 5.x, use cio mount option to mount the redo file system and make sure oracle init.ora parameter filesystemio_options=SETALL.
Do not use CIO mount option on Oracle 11.2.0.2+ and AIX 6.1+ to mount the redo file system.
-
Additional Information
filesystemio_options=SETALL seems to work on HP server.
For 11.2.0.2+, oracle started using O_CIOR option to open the redologs and CIO mount option is no longer recommended for redologs on AIX 6.1+ http://www-01.ibm.com/support/docview.wss?uid=swg21590764 DBV Can Not Access Online Datafiles (DBV-100) If FILESYSTEMIO_OPTIONS=SETALL (Doc ID 360287.1) Recommendations For Using CIO/DIO For Filesystems Containing Oracle Files On AIX (Doc ID 960055.1)
