JR30251: SEQ. JOBS STUCK IN "HUNG" STATE, SINCE PARALLEL JOB COMPLETION WAS NOT DETECTED

APAR status

• Closed as program error.

Error description

• Customer run into a situation where their system was in a hung
  state.  Closer inspection revealed that a Parallel job had
  compelted (and produced the desired output), but the job log did
  not even indicate that the job had started, thus leaving the
  calling seq. job in hung state.
  

Local fix

• N/A
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  Unix platform. Users running many PX jobs may see that some
  jobsdo not seem to finish.
  ****************************************************************
  PROBLEM DESCRIPTION:
  When many PX jobs are run on a Unix system, a return status
  code from the OSH process was not successfully sent through a
  pipe to the running process. This means that the running
  processwill wait forever for the signal, causing the job to
  appear as  though it has hung.
  ****************************************************************
  RECOMMENDATION:
  Install patch patch_JR30251_server_solaris_801ga.tar (or
  equivalent for other platforms). Upgrade to version 8.1.
  This change is included in 8.0.1 Fix Pack 2.
  ****************************************************************
  

Problem conclusion

• Patch created for 8.0.1 GA. The return code will be retrieved
  from a temp file if the read from the pipe failed.
  

Temporary fix
