Under rare circumstances, minor memory leak in catalog cache can occur if the following conditions are met: - RTS (real time statistics) is enabled - Asynchronous RUNSTATS fails with error code SQL0973N. An error message will be logged in the event log for example: 2014-10-13-20.24.37.450827-240 E1732609A716 LEVEL: Event PID : 34275468 TID : 20977 KTID : 91553865 PROC : db2sysc 1 INSTANCE: MYINST NODE : 001 DB : MYDB APPHDL : 0-32854 APPID: *N0.myinst.141013192943 AUTHID : MYINST HOSTNAME: EDUID : 20977 EDUNAME: db2agntp (TEST1C) 1 FUNCTION: DB2 UDB, relation data serv, sqlrLocalRunstats, probe:10070 COLLECT : TABLE AND INDEX STATS : Object name with schema : AT "2014-10-13-20.24.37.450720" : BY "Asynchronous" : start OBJECT : Object name with schema, 36 bytes SCH1 .TAB1 IMPACT : None DATA #1 : String, 10 bytes RTS Daemon 2014-10-13-20.24.37.604352-240 I1732609A1031 LEVEL: Severe PID : 34275468 TID : 20977 KTID : 91553865 PROC : db2sysc 1 INSTANCE: MYINST NODE : 001 DB : MYDB APPHDL : 0-32854 APPID: *N0.myinst.141013192943 AUTHID : MYINST HOSTNAME: EDUID : 20977 EDUNAME: db2agntp (TEST1C) 1 FUNCTION: DB2 UDB, relation data serv, sqlrLocalRunstats, probe:12236 MESSAGE : ZRC=0x8012006D=-2146303891=SQLR_CA_BUILT "SQLCA has already been built" DATA #1 : unsigned integer, 8 bytes 11493 DATA #2 : SQLCA, PD_DB2_TYPE_SQLCA, 136 bytes sqlcaid : SQLCA sqlcabc: 136 sqlcode: -973 sqlerrml: 15 sqlerrmc: CATALOGCACHE_SZ sqlerrp : SQLRC0B3 sqlerrd : (1) 0x8B0F0008 (2) 0x00000008 (3) 0x00000000 (4) 0x00000000 (5) 0xFFFFFFD8 (6) 0x00000000 sqlwarn : (1) (2) (3) (4) (5) (6) (7) (8) (9) (10) (11) sqlstate: 2014-10-13-20.24.37.605996-240 E1732609A923 LEVEL: Event PID : 34275468 TID : 20977 KTID : 91553865 PROC : db2sysc 1 INSTANCE: MYINST NODE : 001 DB : MYDB APPHDL : 0-32854 APPID: *N0.myinst.141013192943 AUTHID : MYINST HOSTNAME: EDUID : 20977 EDUNAME: db2agntp (TEST1C) 1 FUNCTION: DB2 UDB, relation data serv, sqlrLocalRunstats, probe:12313 COLLECT : TABLE AND INDEX STATS : Object name with schema : AT "2014-10-13-20.24.37.605928" : BY "Asynchronous" : failure OBJECT : Object name with schema, 36 bytes SCH1 .TAB1 IMPACT : None DATA #1 : String, 10 bytes RTS Daemon DATA #2 : String, 122 bytes RUNSTATS ON TABLE "SCH1 "."TAB1" ON ALL COLUMNS WITH DISTRIBUTION ON ALL COLUMNS AND INDEXES ALL DATA #3 : String, 26 bytes ZRC=0x8012006D=-2146303891 | |
