In Response To: Re: RE: Light append partition after onpload (JOHAN BACKLUND)


If your customer insists in using the 10.0xC6 version, you should
minimum upgrade to the latest W pack of 10.0 (I think it is W5).
We have found most of the problems we had were solved in this release. I
am not sure about the VP_MEMORY_CACHE_KB bug (we did not run into that
one ...).
This version is a bugfix release, which is recommended, because you can
get into serious problems (stability !) with the unpatched 10.00xC6
Read the known defects/bugfix history for details. I would say you are
much more save using minimum the C6W5 version. We did not encounter any
functional differences between 10.00xC6 and 10.00xC6W5. But of course,
the decision is up to you.

Thanks for the quick response!

This version is used because of requirements from an applicationt this
customer is using. An upgrade to TC7 has been estimated to involve 4-5
months of testing. Since they don't want to delay the migration from
7.31 we just have to play with what we've got.

However, I would be more than interested in some of the worst problems
xC6 because then I could try and navigate the customer past these

I've seen comments that the VP_MEMORY_CACHE_KB bug wasn't present in the
Windows version, but one test did started doing excessive allocation of
segments until it hit SHMTOTAL - but with some 40-50% free space in each
segment. Next week I will run same tests with VP_MEMORY_CACHE_KB=0 and
see if it makes a difference.

Unfortunately, the Informix support goes through the application
supplier, and although they can escalate to IBM, there is a long
turnaround time before a competent answer is returned. And I am
contractor from a small company, so that's why I'm knocking on this
forums door.

Anyways, the customer is still in the testing phase, so none of the
problems I've mentioned have affected production systems. However,
planned migration date is only like 4 weeks away...

> 3. Run oncheck's on problematic tables (-cc, -cI, -cD); dump 'oncheck

Ran all the onchecks I could think of without any problems. I'm not sure
the oncheck -pT output is still available, but if it is I will add it
However, I looked through quite carefully when it happended but could
not see
anything strange - apart maybe from the fact that the table flags did
mention anything about Light Append Partition. This flag was only
present in
the sysmaster:sysptnhdr table.

> 4. Verify, that you are doing Logical log backups properly

hmm, this could be interesting. So far, all the testing has occurred
logical log backups disabled (LTAPEDEV set to NUL). Can this really have

caused the problem?

> 5. Check 'online.log' for any helpful information

online.log reported nothing bad.

thanks again,
