In Response To: ISAM 105 error (MICHAEL HOFFMAN)

Hi,

The device which contains the bad page, it is on a raw disk or some kind of filesystem volume, if so, which type of filesystem?

Are there any messages in the OS logs?

When was a oncheck last run on the affected object?

Have you tried running:

oncheck -cR
oncheck -cc
oncheck -ce

to check everything before the server accesses that object is fine??

It could be a storage issue on an Informix bug (they do happen). We would need to know more about this particular environment to be able to comment.

Regards,
David.
