PK84382: CEXMAIN IF NO DATASTORES ARE DEFINED

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• This APAR will address the following problems:
  - It is possible to activate a message exit that failed to load
    during initialization
  - ABEND0C4 in CEXMAIN if no datastores are defined
  - CEX fails to initialize if there are no PORTS defined in the
    TCPIP command of the HWS configuration member
  - ICON accepts MAXSOC= but CEX fails to initialize in this case
  - ABEND0C4 in CEXTPLST if there are no message exits defined
    in the HWS configuration member
  - The event record DSECT for type 130 does not contain an
    explaination of the CTLWORD field

  The following problems are addressed in this APAR:
  1. It is possible to activate a message exit that failed
  to load during initialization.
  2. 0C4 in CEXMAIN if no datastores are defined.
  3. CEX fails to initialize if there are no PORTS defined
  in the TCPIP command of the HWS configuration member.
  4. ICON accepts MAXSOC= but CEX fails to initialize in
  this case.
  5. 0C4 in CEXTPLST if there are no message exits
  defined in the HWS configuration member.
  6. The event record DSECT for type 130 does not contain
  an explaination of the CTLWORD field.
  7. The 163 OTMA trace record may not contain any
  application data.
  8. Sync callout response not recognized after ICON KB20092
  for IMS Connect V11.
  9. 0C1or 0C4 due to storage overlay building trace record
  164 if inbound application data has LL field with value
  greater than X'8000' The abend usually occurs at entry
  to module FUNTDB01.
  

Problem conclusion

• The following changes have been made to correct these problems:
  1. Changed code to only allow an exit that failed to load
  to be deleted and added.
  2. Changed code in CEXMAIN to prevent 0C4 when no datastores
  are defined.
  3. Corrected CEXMAIN to initialize correctly when no PORTS
  are defined.
  4. Corrected CEXMAIN to correctly initialize when MAXSOC=
  is specified.
  5. Corrected CEXTPLST to not abend when shutdown is posted
  early due to HWS U3401 abend for invalid configuration
  parameters.
  6. Added flag bit meanings to user macro CEXR130 for event
  record 130.
  7. Corrected CEXTECL to include as much application data
  as will fit into the trace buffer instead of excluding
  application data when it was larger than the remaining
  space in the trace buffer.
  8. Corrected CEXEXRTR to tollerate the change in PK20092
  that sets a Sync Callout Response as a SENDONLY message.
  9. Corrected the technique used to make sure the amount of
  application data traced did not exceed the trace buffer.
