Greetings VM List! We recently moved a database from DB2 9.5 running on SLES10 SP4 to DB2 10.5 (fix pack 5) running on SLES11 SP3, both under z/VM 6.2. We're having some issues with increased memory consumption and wondered if anybody else had noticed a similar trend. To give a little background the old guest ran wonderfully efficiently for a number of years with 2G of memory allocated to the guest. The new guest has been sized up through the testing period to 8G and we're still having problems. The recommended mode for DB2's memory management is to run with its automatic memory management feature enabled. This seems, however, to just gobble up all the memory we can give it and has led to the guest freezing until we remove the load from the application running queries, at which time it becomes responsive again. Any advice on either OS configuration parameters (beyond what IBM recommends here: http://www-01.ibm.com/support/knowledgecenter/SSEPGG_10.5.0/com.ibm.db2.luw.qb.server.doc/doc/c0057140.html?cp=SSEPGG_10.5.0%2F2-0-1-2-2-0-10-1) to be aware of or DB2 configuration that might help us with this would be enormously appreciated.
