Dear Sun Managers,

We are facing a problem with our Sun setup.

We are running Oracle 9i on Sun Cluster 3.1 with VxVM. Shared storage is on the Sun 6320 array.

We are facing some performance issue with Oracle intermittently. Whenever we have the performance issue, we are able to see the following error in the alert_RADH.log under Location: $ORACLE_BASE\admin\RADH\bdump

Error message: WARNING: aiowait timed out

We want to know what exactly this error means, and what to be done to fix the slow performance problem.

When we checked with Oracle, what they are saying is that it is an operating system. I posting this query here hoping that some will be able to help me out.

Any help would be highly appredciated
