The db2diag.log can show entries like below 2014-08-14-04.15.02.177154-300 I92297A659 LEVEL: Warning PID : 41746466 TID : 15704 PROC : db2sysc 0 INSTANCE: db2inst1 NODE : 000 DB : SAMPLE APPHDL : 0-289 APPID: 111.123.45.67.12345.992233123456 AUTHID : USER1 HOSTNAME: server1234 EDUID : 15704 EDUNAME: db2agent (SAMPLE) 0 FUNCTION: DB2 UDB, runtime interpreter, sqlriPEXInitHashTable, probe:3194 DATA #1 : unsigned integer, 4 bytes 4 DATA #2 : unsigned integer, 4 bytes 2 DATA #3 : unsigned integer, 8 bytes 211817 DATA #4 : unsigned integer, 8 bytes 476851 DATA #5 : unsigned integer, 8 bytes 199379 2014-08-14-04.15.02.201086-300 E92957A527 LEVEL: Warning PID : 41746466 TID : 15704 PROC : db2sysc 0 INSTANCE: db2inst1 NODE : 000 DB : SAMPLE APPHDL : 0-289 APPID: 111.123.45.67.12345.992233123456 AUTHID : USER1 HOSTNAME: server1234 EDUID : 15704 EDUNAME: db2agent (SAMPLE) 0 FUNCTION: DB2 UDB, runtime interpreter, sqlriPEXInitHashTable, probe:3229 MESSAGE : . The above warnings are normal behaviour which indicate that db2 could not get the ideal amount of sort memory at that point in time, so it decided to use a reduced amount. Since these are just normal warning messages, this db2diag.log entry will be removed. The information about this form of post-threshold sort is still available to users using the preferred monitoring technique of using database monitor output. For example: Using Partial early distincts threshold monitor element http://www-01.ibm.com/support/knowledgecenter/SSEPGG_10.1.0/com. ibm.db2.luw.admin.mon.doc/doc/r0058845.html | |
