Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• DSNT038I DSNTRVFY - THE WLM ENVIRONMENT xxxxxxxx IS NOT
  AVAILABLE
  The above message is issued even though the z/OS command
  -D WLM,APPLENV=xxxxxxxx
  shows that the APPLENV is defined.
  This happens when a large number of WLM environments defined
  in system. The reported case has 700 WLM environments defined.
  

Local fix

• Use a smaller number of WLM enviornments.

  ****************************************************************
  Currently, the program DSNTRVFY allocates a 32K buffer to
  store the output of the DISPLAY WLM,APPLENV=* command.
  If the command output is larger than 32K, information for one
  or more WLM application environments is lost. In this case,
  when the program DSNTRVFY attempts to look for a valid WLM
  application environment that is part of the command output
  that did not fit in the buffer, the search fails and the error
  "DSNT038I DSNTRVFY - THE WLM ENVIRONMENT xxxxxxxx IS NOT
  AVAILABLE? is issued. Also the message DSNT028I indicates
  a blank state and a NUMTCB of 0.
  

Problem conclusion

• In response, this APAR corrects the problem by increasing
  the buffer size from half word to full word.
