APAR status

  • Closed as program error.

Error description

  • When UID is larger than operating system's maximum value for
    integer, all CLP will fail and timeout with the error below:
    
    DB21015E  The Command Line Processor backend process request
    queue or input
    queue was not created within the timeout period.
    Update DBM cfg SYSADM_GROUP errcode = 8
    
    Sample output from AIX, UID is larger than AIX's maximum value
    2147483647 which can be held by integer data type.
    $ id db2inst1
    uid=4039207222(db2inst1) gid=2139207222(db2adm)
    groups=209(db2test)
    UID  number is larger than AIX's maximum value for integer
    (2147483647)
    
    
    
    AFFECTS:
    Upgrading to v10.5 FP11
    DB2 v11.1 and v11.5
    

Local fix

  • Revert to v10.5 FP10 if DB2 instance was upgraded to FP11
    OR
    Use operating system commands to change UID to number that is
    smaller. This would also require ownership change for database
    files  (<instance name>/NODE0000/...),  DB2 instance home
    ($HOME/<instance name>), etc... since existing files created
    with older UID would now have no owner
