Hi Everyone,
=20
II 9.0.4 (a64.lnx/105)NPTL + patch12707
=20
I have a horriblly long query which generates E_UL000B_NOT_ALLOCATED.
The query is using a series of case statements to pivot a table. There
is one case statement per column.
eg select pid
, max(case when name=3D'sv1' then value end) as sv1
,max(case when name=3D'sv7' then value end) as sv7
,max(case when name=3D'sv8' then value end) as sv8
,max(case when name=3D'sv9' then value end) as sv9
,max(case when name=3D'sv10' then value end) as sv10
,max(case when name=3D'sv11' then value end) as sv11
,max(case when name=3D'sv12' then value end) as sv12
,max(case when name=3D'sv13' then value end) as sv13
,max(case when name=3D'sv15' then value end) as sv15
etc...
from string_value_best_case=20
where mod(pid,10)=3D1
group by pid;
=20
If the query has <=3D40 case statements it works fine. But if it has >40
it crashes (and occasionally takes out the server) with the following
in the errlog:
E_UL000B_NOT_ALLOCATED Attempt to perform some ULM operation on a
memory pool that was not allocated by you.
E_QE009C_UNKNOWN_ERROR Unexpected error received from another
facility. Check the server error log.
E_UL000B_NOT_ALLOCATED Attempt to perform some ULM operation on a
memory pool that was not allocated by you.
E_QE009C_UNKNOWN_ERROR Unexpected error received from another
facility. Check the server error log.
E_SC0216_QEF_ERROR Error returned by QEF.
E_SC0206_CANNOT_PROCESS An internal error prevents further processing
of this query.=20
Associated error messages which provide more detailed information about
the problem can be found in the error log, II_CONFIG:errlog.log
=20
Now here's the kicker...
The basic query has been working fine with much higher numbers of
columns when their data type has been integers, dates and float4. But
when I switched the query to work on varchar(25) types it has suddenly
developed this limit.
=20
Anyone got any ideas what might be causing this and how to fix it?
=20
In the meantime I'm going to try and bump the QEF memory and see if that
helps....
