Produkt: | |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 | |
Problembeschreibung: | |
Queries on ADMSINTABINFO are slow even if all TCBs are loaded in memory already. I set DBHEAP to 40000, should be able to store 20000 tables' TCB info, actually about 10000 tables in that db. Check with "db2pd -db testdb -tcb" to make sure all tables TCB was in DBHEAP. time db2 "select tabname from sysibmadm.admintabinfo where reorg_pending='Y'" TABNAME ---------------------------------------------------------------- ---------------------------------------------------------------- ADMIN99 ADMIN999 2 record(s) selected. real 2m48.74s user 0m0.01s sys 0m0.01s I still saw bufferpool data read as below Buffer pool data logical reads = 337188 Buffer pool data physical reads = 323543 | |
