IV16589: INSTALLER HANGS ATTEMPTING TO INSTALL LZ AGENT

IBM Tivoli Monitoring 6.2.2 Fix Pack 9 (6.2.2-TIV-ITM-FP0009)

APAR status

• Closed as program error.

Error description

• PROBLEM DESCRIPTION:
  
  On some systems, the installer hangs while attempting to install
  an agent. In the problem environment, the process tree showed
  "bash -l" as the hanging process underneath ITM's install.sh and
  it's Java programs.
  
  RECREATE INSTRUCTIONS:
  We were unable to recreate this problem in-house. We diagnosed
  the problem by analyzing the reporting customer's process tree,
  ITM trace logs, and the corresponding ITM source code. We proved
  a prototype solution using a diagnostic patch that was shown to
  provide relief.
  
  As part of internal testing, we did that the "#!<interpreter>"
  function is disabled for scripts invoked on the problem paths.
  For example,
  scripts with "#!/bin/ksh" are always run under Bourne shell
  (bash via /bin/sh) instead of Korn shell (/bin/ksh). This is an
  artifact that goes away at the same time as the reported
  symptom.
  
  LOCAL FIX:
  No workaround available.
  

Local fix

• No workaround available.
  

Problem summary

• The install.sh process hangs on Linux or UNIX.
  
  
  The installer hangs while attempting to install a given
  component on Linux or UNIX. The symptom was originally reported
  for the Linux OS agent, but it can occur for virtually any IBM
  Tivoli Monitoring component. When this particular case occurs,
  the process tree shows a non-IBM Tivoli Monitoring child process
  of the IBM Tivoli Monitoring installer waiting for a prompt. In
  the problem case, the child process was "bash -l".
  

Problem conclusion

• The code was changed to launch commands using
     the form "/bin/sh -c <command>" instead of "sh -c <command>"
  or
     "sh <command>".

  packages:
