Error description

  • Tivoli Storage Productivity Center 5.2.x users monitoring large
    environments may encounter DB2 transaction log full errors if
    small values for the DB2 parameters LOGFILSIZ, LOGPRIMARY,
    LOGSECOND, LOGBUFSZ are used, particularly when performance
    monitors are scheduled to run every minute.
    
    The problem can surface in Tivoli Storage Productivity Center in
    a variety of ways.  It may be a failed upgrade, a failed action
    (e.g. deleting a storage system), a failed probe, or a variety
    of other issues.  Investigation into the Tivoli Storage
    Productivity Center and DB2 logs provides confirmation of this
    condition.
    
    The Tivoli Storage Productivity Center logs will display the SQL
    errors:
     SQLCODE=-964, SQLSTATE=57011
    The db2diag log file will show:
          "Log File has reached its saturation point"
          DIA8309C Log file was full.

Problem conclusion

  • Users experiencing this should upgrade to Tivoli Storage
    Productivity Center 5.2.7 or higher or modify the values for the
    following DB2 parameters:
    LOGFILSIZ, LOGPRIMARY, LOGSECOND, LOGBUFSZ
    
    Steps to check and modify the DB2 parameters:
    1.  Open a DB2 command window:
    2.  Run the following command to verify that the current values
    of the mentioned DB2 parameters are lower than the ones
    indicated at step 3.
    db2 get db cfg for tpcdb > tpcdb_cfg_current.txt
    3.  Open file tpcdb_cfg_current.txt and search for LOGFILSIZ,
    LOGPRIMARY, LOGSECOND, LOGBUFSZ
    4.  If they are smaller than 20000, 100, 150, 512 then run step
    5.
    5.  Issue the following commands, one by one in this specific
    order, to increase the DB2 parameters:
    db2 update db cfg for tpcdb using LOGFILSIZ 5000
    db2 update db cfg for tpcdb using LOGSECOND 240
    db2 update db cfg for tpcdb using LOGPRIMARY 16
    db2 update db cfg for tpcdb using LOGBUFSZ 512
    
    The fix for this APAR is targeted for the following maintenance
    package:
    
    | refresh pack | 5.2-TIV-TPC-RP0007 - target August 2015
    
    http://www-01.ibm.com/support/docview.wss?&uid=swg21320822
    
    The target dates for future refresh packs do not represent a
    formal commitment by IBM. The dates are subject to change
    without notice.
    Note: You must ensure there is adequate disk or file system
    space before you modify the LOGFILSIZ, LOGPRIMARY, and LOGSECOND
    parameters. These values will result in approximately 5 GB of
    log file space.
    The values suggested here will be the default values with Tivoli
    Storage Productivity Center 5.2.7
    If the DB2 transaction log full errors continue after increasing
    these parameters as suggested or upgrading to Tivoli Storage
    Productivity Center 5.2.7 or higher, contact IBM Support for
    further investigation.
