PM72199: MISLEADING MESSAGE: DFS1921I KEYWORD PARAMETER INVALID, CLASS =

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• PM48203 introduced IMS startup parameter RCLASS, which may be
  specified in either or both of DFSPBxxx, DFSDCxxx.
  If RCLASS is specified in both, the following information
  message is invalidly issued at IMS startup:
    DFS1921I - KEYWORD PARAMETER INVALID, CLASS   =
  ..
  DFSIIDC0 subroutine PROCRCLA logic fails to move R6 past the
  RCLASS=value statement when a value for RCLASS has already been
  supplied in DFSPBxxx.  This causes DFSIIDC0 keyword scanning
  logic to be entered a 2nd time for keyword=value "CLASS=xxx'
  (i.e. one byte forward from the previous successful keyword
  scan), which results in keyword not found and DFS1921I.
  ..
  Additional search words: RGRCLASS IDCRCLAS IDCNXTKW IDCSCAN
            IMSV13COEX/K  IMSV12COEX/K
  

Local fix

• None. Ignore the message. IMS start up continues normally using
  the RCLASS value specified in DFSPBxxx, as documented.
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: All IMS V11 users of RCLASS in proclib       *
  *                 member DFSDCxxx.                             *
  ****************************************************************
  * PROBLEM DESCRIPTION: DFS1921I - KEYWORD PARAMETER INVALID,   *
  *                      CLASS =                                 *
  ****************************************************************
  * RECOMMENDATION: INSTALL CORRECTIVE SERVICE FOR APAR/PTF      *
  ****************************************************************
  When RCLASS has been specified in the DFSPBxxx proclib
  member or in PARM1/PARM2 then the code in module DFSIIDC0
  will find it and will not override it.  But it failed to
  skip the keyword and parameter so the byte after RCLASS
  gets treated as a new keyword which leads to:
  DFS1921I - KEYWORD PARAMETER INVALID, CLASS   =
  

Problem conclusion

• GEN:
  KEYWORDS:
  
  *** END IMS KEYWORDS ***
  Code has been moved in module DFSIIDC0 to make sure that
  the keyword/parameter has been skipped if it has been
  defined in DFSPBxxx proclib member.
