  CUSTOMERS WHO HAVE VSAM (DFP) 310 INSTALLED (AND PARTICULARLY
  CUSTOMERS WITH FILES THAT HAVE ALTERNATE INDEXES OR AIX),
  MAY EXPERIENCE VARIOUS DIFFERENT ABENDS. THE FOLLOWING ARE
  SEVERAL PROBLEMS RESOLVED BY VARIOUS DFP 310 APARS.
  ****************************************************************
    DFP APAR OY19373 DESCRIBES A PROBLEM WHICH OCCURS ON THE
  SHOWCAT FOR THE AIX WHEN CICS OPENS A FILE THAT HAS AN AIX
  DEFINED. AN INVALID RETURN CODE, X'20' IS RETURNED AND CAUSES
  VARIOUS SYMPTOMS. VARIOUS ABENDS KNOWN TO OCCUR ARE:
      ABEND301 ABEND202 ABEND0C4 ABEND0C6 MSGDFH0401 MSGDFH0405
      MSGDFH0601 ABENDASRA ABENDS301 ABENDS0301 ABENDS202
      ABENDS0202 (NOTE OTHER ABENDS MAY OCCUR ALSO)
  IF THERE IS NO ABEND, THEN CICS ISSUES A MSGDFH0956 8117,020.
  THE SYMPTOM STRING WILL NORMALLY INDICATE THE FAILING MODULE IS
  DFHFCN OR DFHFCS.
    AFTER APPLYING OY19373, A RE-IPL MUST BE DONE TO PICK UP THE
  MAINTENANCE. PLEASE NOTE THAT A REFRESH OF THE LPA IS NOT
  SUFFICIENT.
  ****************************************************************
    ANOTHER PROBLEM THAT MAY OCCUR AFTER GOING TO DFP R310
  IS AN ENDLESS WAIT ISSUED FROM THE UPAD EXIT (DFHFCX) WITH AN
  ECB THAT IS ABOVE THE 16 MEG LINE. THIS ECB SHOULD POINT WITHIN
  OUR VSWA BUT IS INSTEAD WITHIN A VSAM INTERNAL RPL. THIS PROBLEM
  CAN ALSO RESULT IN A PROGRAM CHECK (ABEND0C4) IN DFHKCP OR
  DFHVSP IF VSAM SUBTASKING IS USED. ALSO IF SUBTASKING IS USED,
  MSGDFH0900 AND MSGDFH0902 IS ISSUED.
  THE ABEND IN DFHKCP CAN BE AT LABEL KCTDCIIO WITH
  FIELD DCATCEA INVALID.
    THIS PROBLEM CAN BE CORRECTING BY APPLYING DFP APAR OY18453.
    IF THE CUSTOMER IS RUNNING DFP R230, R231, OR R300. APAR
    OY13351 WILL ALLEVIATE THE SAME PROBLEM
  ****************************************************************
    DFP APAR OY20505 DESCRIBES A PROBLEM WITH AN ABEND0C4 IN
  IGG0CLX0. IF VSAM SUBTASKING IS USED, MSGDFH0900 AND MSGDFH0902
  WILL BE ISSUED FROM CICS. VARIOUS SYSTEM ABENDS MAY OCCUR AS
  WELL WHETHER VSAM SUBTASKING IS USED OR NOT.
  ****************************************************************
    ONE MORE PROBLEM SEEN WITH DFP R310 IS OPEN ERRORS WITH
  MSGDFH0977 RC8114 RC08. THIS PROBLEM OCCURS BECAUSE WE RECEIVE
  A BAD RETURN CODE ON THE SHOWCAT FOR THE FILE. OY20135 SHOULD BE
  APPLIED TO RESOLVE THE MESSAGE.
  ****************************************************************
   ANOTHER PROBLEM IS RESOLVED BY APAR OY22427 AND THIS DEALS WITH
  ALLOCATING HIPERSPACE BUFFERS. THE SYMPTOM THAT SHOWS UP IS A
  CICS MSGDFH0995. THIS IS A RESULT OF CICS RECEIVING A RETURN
  CODE OF 44 (X'2C') BACK FROM VSAM AFTER ISSUEING THE BLDVRP.
