EXTENT MOVEMENT FAILS WITH SQLE_RC_DUP_TASK_ID "THIS TASK ID ALREADY EXISTS" | |

Problem description: | |
A single DB2 UDB instance contains multiple databases. On each such database there has been an operation requiring an extent movement, for example a new container has been added to a tablespace. If the respective extent movement operations start at around same time, and if the tablespaces where the extent movement is about to begin share the same tablespace ID, the extent movement may fail with an SQLE_RC_DUP_TASK_ID error reported by "sqlbSpawnExtentMovementIcoord, probe:5015", indicating that a duplicate extent movement task has been submitted. A sample db2diag.log message: 2009-12-03-14.57.12.915728-300 I251906E516 LEVEL: Severe PID : 18874 TID : 479610986765 PROC : db2sysc INSTANCE: db2inst1 NODE: 000 DB : SAMPLE APPHDL : 0-266 APPID: *LOCAL.db2inst1.091203195635 AUTHID : DB2INST1 EDUID : 168 EDUNAME: db2agent (SAMPLE) FUNCTION: DB2 UDB, buffer pool services, sqlbSpawnExtentMovementIcoord, probe:5015 MESSAGE : ZRC=0x80050153=-2147155629=SQLE_RC_DUP_TASK_ID "This task ID already exists" This is a timing dependent error. The fundamental problem is that extent movement tasks are currently using an identifier that is not sufficiently unique. The purpose is to improve the design of the task identifier. | |
