Re: IDS down while log back. is it a bug?

In Response To: Re: IDS down while log back. is it a bug? (NETSKY LIAO)

Hi,

the problem is, that secondary server tries to backup the
logical log 3222 as it gets full. This should not be the case.
Backup (of logs and dbspaces) should happen on primary
server only. On secondary backup should be disabled, i.e.
backup attempts should be rejected (but not crash the
server). In your case the logs are backed up on primary,
and that is OK and should be sufficient.

I'm not sure how/why in your case it happens that log backup
is triggered on the secondary. This needs further investigation.
My guess is that it is a combination of a specific configuration
and possibly a defect in IDS - but that is just a guess, because
a definite statement is not possible from the information given.

Therefore I advise to open a call (aka PMR) with IBM Informix
Tech Support. They will be able to figure out and understand,
why this happens. Then they will determine whether this really
is a defect, whether it (still) occurs in current versions of IDS
and if so, where/how it can be fixed. Or in which version of IDS
it is already fixed so that you can use that. Or what you can do
as a workaround to avoid the problem.

Regards,
Martin
