I am running a executeBatch() statement containing delete statements through java code. This batch runs very slow in db2. Also I am unable to monitor/track as in which delete statement is causing the batch to run slow.
Please help me on this.
Thanks in advance.

Re: executeBatch statement containing delete queries is slow in db2 environment2012-11-02T21:36:32Z in response to SystemAdminMay be something like this:
select stmt_text from table(mon_get_pkg_cache_stmt('D',null,null,null))
order by TOTAL_CPU_TIME/NUM_EXEC_WITH_METRICS desc
fetch first 10 rows only
