PH24513: CEMT DISCARD WITH LOWER CASE LIBRARY NAME CAUSES AEXZ / DFHLD0002 DUMP

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When the library name is specified in lower case, within a
  
  cemt library(file1) discard
  we get a dump for an AEXZ abend and
  see message
  +DFHLD0002 A SEVERE ERROR (CODE X'8205') HAS
  OCCURRED IN MODULE DFHLDLB2.
  
  If the command uses the same
  name, but specified in uppercase
   cemt library(FILE1)
  discard
  there is no abend.
  
  When the CEMT DISCARD was issued
  with a library name in
  upper case, but for a non-existent
  library XXXX resource,
  the CEMT screen just shows a NOT FOUND
  error message and
  again no abend took place.
  

Local fix

• Ensure that the CEMT command is entered with the
  library name
  in uppercase.

  * PROBLEM DESCRIPTION: An attempt to discard a CICS LIBRARY    *
  *                      definition using a lower case library   *
  *                      name results in an abend,               *
  ****************************************************************
  A request is made by CEMT, CECI or EXEC CICS to DISCARD
  a library definition specifying the library name
  in lower case characters.
  The requesting program suffers an abend AEXZ because the
  library name is in lower case.
  

Problem conclusion

• DFHLDLB2 has been changed to detect the lower case name
  and return NOTFND to the requesting program.
  CEMT now returns NOT FOUND to the user.
  CECI and EXEC CICS DISCARD now return NOTFND.
  The user can discard the library by specifying the
  library name in upper case characters.
