The dynamic statement '*sh1731692265_0874276115ss*' could not be found.


Our application is getting a lot of the following errors :

Caused by:
com.sybase.jdbc4.jdbc.SybBatchUpdateException: JZ0BE: BatchUpdateException:
Error occurred while executing batch statement: The dynamic statement
'*sh1731692265_0874276115ss*' could not be found. This may be due to
insufficient metadata descriptors. Increase the serverwide 'number of open
objects' parameter or the 'procedure cache size' parameter.

sp_monitorconfig 'all' shows that number of open objects is used less then 60%.

I've increased the procedure cache size, but the problem persists.

It is always the same query, and the problem can be reproduced.

I have executed :

dbcc procbuf

and found the name mentioned in the error :

I want to remove this procedure from the cache.

The only command I know that accepts an id is purgesqlcache, but I assume that this removes an entrie from the statement cache.

Anyway, I gave it a try.

> dbcc purgesqlcache(1731692265);

DBCC execution completed. If DBCC printed error messages, contact a user with System Administrator (SA) role.
Statement (id=1731692265) not found in the cache.

Ok, as expected.

I ran dbcc proc_cache(free_unused) which removed the proc_buf above. (and a lot more :-) ).

I have to wait until tomorrow when our programmers are back at work to know if this solved the problem.

In the meanwhile I want to ask if there is something I'm missing, or if there are anything else I should try/execute when this problem persists/returns.

We're running ASE 15.7 SP134 on solaris intel.
