| We are about to 'stress test' our DB2 environment. I've played with db2mtrk off and on, trying to figure out how it's mapping the memory to its components. If I have the following output: Memory for instance fcmbp monh other 16.7M 176.0K 5.7M Memory for database: <DB2_NAME> utilh pckcacheh catcacheh bph bph bph bph 32.0K 1.7M 896.0K 4.2M 31.5M 314.5M 31.5M bph bph bph bph bph shsorth lockh 4.2M 640.0K 384.0K 256.0K 192.0K 160.0K 480.0K dbh other appctlh appctlh appctlh appctlh appctlh 12.1M 32.0K 16.0K 16.0K 16.0K 16.0K 32.0K appctlh appctlh appctlh appctlh appctlh appctlh appctlh 32.0K 32.0K 16.0K 32.0K 32.0K 32.0K 32.0K appctlh appctlh appctlh appctlh appctlh appctlh appctlh 32.0K 32.0K 48.0K 32.0K 16.0K 32.0K 16.0K appctlh appctlh appctlh appctlh appctlh appctlh appctlh 32.0K 32.0K 144.0K 32.0K 16.0K 32.0K 32.0K appctlh appctlh appctlh appctlh appctlh appctlh appctlh 32.0K 32.0K 32.0K 32.0K 16.0K 32.0K 32.0K appctlh appctlh appctlh appctlh appctlh appctlh appctlh 32.0K 32.0K 32.0K 32.0K 32.0K 32.0K 16.0K appctlh appctlh appctlh agsh 32.0K 32.0K 80.0K 94.0M I can see that there is memory allocated for bufferpools, app ctl heaps, locks, etc etc. This snapshot was taken with 2 active connections both crunching a query. In our stress test, we plan on having upwards of around 40 connections at once 'going to town', My question is (finally), with that many connections, and with the output above, how will I be able to see what's going on? Will I be able to tell if there really is a memory leak? How will I be able to deduce this information? Thanks, Chris |
