Additionally, our DB and LOG stats are as follows - I believe there is
plenty of DB space for the select to complete;

Subject: SELECT statement crashes server
Hallo *SM'ers
AIX 5.2.0.0
TSM server 5.2.2.3
I have discovered a select command that will crash our server instantly
every time..
Could anyone confirm they get the same behaviour, or that it's just a
quirk of our site.
I originally tried this;
>select volume_name,pct_reclaim from (select * from volumes where
stgpool_name='UKS_NORM_PRIM') where pct_reclaim=>90
But TSM complains about the first '(' being an invalid token... It
shouldn't be.
So, after confirming and doing succesfull sub-selects in other select
commands, I thought it may have something to do with the '>' being the
redirect symbol. So I wrapped part of the command in double-quotes
When I try this command;
>select "volume_name,pct_reclaim from ( select * from volumes where
stgpool_name='UKS_NORM_PRIM') where pct_reclaim=>90"
The server instantly falls over.....
Can anyone else repeat this? I have tried a couple of very simple select
commands with double quotes around them (none using '>' as yet) and
only the above select command has made the TSM server fall over so far..
but my testing is far from comprehensive as yet.
Have Fun!
Thanks,
Matt.
