Depending on your DB2 UDB configuration you may see SQLCODE
-444 error messages when routing polymorphic (map chain) documents.
These error messages would be located in the file {INSTALL DIR}\was\profiles\bcgdocmgr\logs
\bcgdocmgr\bcg_router.log as well as <DB2Home>\SQLLIB\bin\db2diag.log.
If you see this message you should increase the value of the DB2
Database Manager parameter SHEAPTHRES. This parameter should be
at least two times the largest sortheap value defined for any database
within the DB2 instance. A sample command is given below:
db2 UPDATE DBM CFG USING SHEAPTHRES xxxxx IMMEDIATE
If the SQLCODE -444 persists after changing the value of SHEAPTHRES, you may also need to decrease the values of STMTHEAP and APPLHEAPSZ for your WPG database. A sample command is given below:
db2 UPDATE DB CFG FOR <dbname> USING STMTHEAP xxxxx
db2 UPDATE DB CFG FOR <dbname> USING APPLHEAPSZ xxxxx
Please consult your DBA or refer to your DB2 Administrator's Guide before changing any settings.
