  ****************************************************************
  When opening an extended non-RLS ESDS file error message
  DFHFC0966 is issued. However this behaviour is not mirrored
  by an extended RLS ESDS file. In this case the open is
  successful but any following read request fails with an
  ILLOGIC 110 due to a VSAM return code of 080068.
  
  This is only an issue at releases prior to CICS TS V3.2 which
  supports extended ESDSs.
  

Problem conclusion

Comments

• DFHFCRO has been altered to do a point to a file
  during open processing. If the point fails with VSAM return code
  080068 then new message DFHFC0509 will be issued and the open
  request will fail.

  In the bulleted list headed with the words "CICS supports access

  of the Entry-sequenced data set(ESDS) bullet to read
  "Attempts to open data sets defined with the extended attribute
  fail with error message DFHFC0966, codes 8504, 0008,0068 for

  DFHFCxxxx messages needs to be altered.
  Add in between the descriptions for messages DFHFC0508 and
  DFHFC0510 the following new message.
  "DFHFC0509 applid RLS OPEN of file filename failed. This file is
  an extended entry-sequenced data set (ESDS). The extended file
  attribute is not supported in this release of CICS.
  
  Explanation: While CICS was opening file filename, CICS received
  a nonzero return code from VSAM while attempting to verify that
  relative byte address (RBA) access is allowed. This failure
  indicates that filename is an extended ESDS, which is not
  supported at this release of CICS.
  
  System Action: CICS continues processing with file filename
  closed and its state UNENABLED. Any transaction that attempts to
  use the ESDS RLS file is sent a NOTOPEN condition.
  
  User Response: Redefine filename as a standard ESDS.
  
  Destination: Console
  
  Modules: DFHFCRO
  
  XMEOUT Parameters: applid, filename"
