Error description

  • 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:

    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'.

    (Note the time delay)
    Initial Impact:
    Medium
    Additional Keywords:

Local fix

  • 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.
