APAR status

  • Closed as program error.

Error description

  • The watchdog component of the OS Agent for Unix and Linux calls
    the "cinfo" command to check agent status and get instance
    information.  Sometimes the "cinfo" command does not return a
    value which can result in the process for the command not
    terminating.
    

Local fix

  • Watchdog can be disabled with the following steps:
    
    Edit the lz.ini or ux.ini and comment out the line the starts
    with KCA_CAP_DIR.  (Note the value on the right might have a
    slightly different value based on the release).
    
    #  KCA_CAP_DIR=$CANDLEHOME$/config/CAP:/opt/IBM/CAP
    and add the line
    KCA_CAP_DIR=
    
    Stop and restart the OS Agent.
    

Problem summary

  • Watchdog calls to cinfo sometimes do not terminate.
    
    When the watchdog utility which is part of the OS agent issues
    calls to the "cinfo" command sometimes the calls do not
    terminate which results in extraneous "cinfo" processes running
    in the background.  This can occur on either the UNIX or Linux
    OS agents.
    

Problem conclusion

  • Code has been updated to terminate an externally
    launched command that has not terminated after twenty minutes.
    Commands can include calls to "cinfo" and "itmcmd".
    
    The fix for this APAR is not supported on the following
    platforms due to threading issues in the kernel:
    li6243 - Linux Intel R2.4 (32 bit)
    ls3243 - Linux S390 R2.4 (31 bit)
    ls3246 - Linux S390 R2.4 (64 bit)
    
    
    The fix for this APAR is contained in the following maintenance
    packages:
    
      | fix pack | 6.2.2-TIV-ITM-FP0006
      | interim fix | 6.2.2.2-TIV-ITM_UNIX-IF0009
      | interim fix | 6.2.2.2-TIV-ITM_LINUX-IF0008
      | interim fix | 6.2.2.3-TIV-ITM_UNIX-IF0004
      | interim fix | 6.2.2.4-TIV-ITM_UNIX-IF0005
      | interim fix | 6.2.2.4-TIV-ITM_LINUX-IF0003
      | fix pack | 6.2.2-TIV-ITM-FP0006
    

Temporary fix

  • Watchdog can be disabled until the fix can be applied.
    
    - Edit the < lz | ux >.ini and comment out the line that starts
    with KCA_CAP_DIR.
      (Note the value on the right might have a slightly different
    value based on the release).
    #  KCA_CAP_DIR=$CANDLEHOME$/config/CAP:/opt/IBM/CAP
    and add the line
    KCA_CAP_DIR=
    
    - Stop and restart the OS Agent
