PH36104: IP ADDRESS RULE AND CONTROL EVENT X'00' ENHANCEMENTS

Obtain the fix for this APAR.

APAR status

• Closed as new function.

Error description

• 1. A customer sometimes has a rogue client start looping,
  flooding IMS Connect with repeated request. They want an
     option to protect IMS connect/IMS by blocking message from
     particular IP.
  2. A customer has a vendor product which is used by developers,
     from their PC to IMS through IMS connect with a message exit
     provided by vendor, for this exit, we don't want to apply IP
     rule because the vendor product will verify TSO id of each
     developer.
  3. A customer is running ICON on two LPARs. Both ICONS have the
     same name. They sent in two journals. Both have the same
     CERE_00_VAR_CNAME so it is impossible to distinguish between
     the two.

Problem conclusion

• 1. IP Address rules are enhanced to include a new option to
     'block' message. Any message arriving in IMS Connect from
      that  IP Address is rejected with an RSM.
  
  2. The exit definition has a new option to exclude messages from
     IP Address Rule processing.
  
  3. The control event x'00' record is enhances with the CVTSNAM,
     the SMFID, and the IMS Connect version information derived
     using the DFSGVRM API.
