IC67988: INCREMENTAL BACKUP CAN HANG WHEN PROCESSING A DIRECTORY WITH MANY FILES
Closed as duplicate of another APAR.
The Tivoli Storage Manager Backup/Archive client can hang for a long period of time when backing up to a 6.1 or higher server. When a directory is encountered with a large number of objects, the Backup/Archive client can hang until it ends abnormally either by cancelling or by timing out and causing ANR0530I on the TSM server. Tivoli Storage Manager Versions Affected: 6.1 servers on all platforms Customer/L2 Diagnostics: A trace with the DBCLI trace class may show multiple long running queries for the client which hangs: 07:19:55.973 ￭4496￹￭tbcli.c￹￭6555￹￭BuildStmt￹:EXITING rc=0 with stmt 'SELECT NODEID,FSID,OBJTYPE,HL,LL,STATE,INSDATE, OBJID,DEACDATE,OBJINFO,OWNER,MCID,CGID,STG_HINT,GROUPTYPE, GROUPID,HLID,LLID FROM "TSMDB1"."BACKUP_NAMEVIEW" WHERE (NODEID=? AND FSID=? AND OBJTYPE=? AND HL LIKE ?) ORDER BY HL, LLID, STATE, INSDATE, OBJID FOR READ ONLY OPTIMIZE FOR 10 ROWS WITH UR --4496'. 07:35:23.834 ￭4496￹￭tbcli.c￹￭4216￹￭RdbPrepareAndExecuteStmt￹: Exit with rc 0 (sqlRc 0)(caller imbkqry.c(1155)). (Note the time delay) Initial Impact: Medium Additional Keywords: TSM zz61 slow hang timeout baclient
Exclude the directory or directories which the Backup/Archive client is processing when the hang occurs. Alternately, use selective backup to work around the problem. Install fixing maintenance when available.
