PH69402: UPDATE SDD TO SUPPORT OVER 100 RESOURCES FOR SINGLE ORIGIN TRANSACTIONS

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Currently the XSDT block used by security discovery to capture
  security discovery data (SDD) can handle up to 100 resources
  for each origin/transaction combination.
  
  For most transactions this is significantly more than enough
  space. However, some user transactions access over 100
  resources. This can lead to some resources being missed in the
  SDD output for transactions that accessed over 100 resources.

Problem summary

• ****************************************************************
  * USERS AFFECTED: All CICS users.                              *
  ****************************************************************
  * PROBLEM DESCRIPTION: Resources are missed by CICS security   *
  *                      discovery for transactions that access  *
  *                      over 100 resources.                     *
  ****************************************************************
  When a single origin/transaction combination accesses 100
  resources, any further resources accessed via this
  origin/transaction combination will not be stored in the XSDT
  block. In this case, any further resource access will never be
  recorded by security discovery into the DFHSECD logstream
  which stores the security discovery data (SDD) records.
  
  Since these resources were not recorded into the DFHSECD
  logstream, DFH$SDDP will produce an incomplete SDD file as these
  resources which were not stored in the XSDT block will be
  ignored.
  

Problem conclusion

• CICS security discovery has been updated to record over 100
  resources from a single origin/transaction combination.
  
  This APAR also fixes an issue where new entries were not
  initialised correctly. These were subsequently missed from the
  final SDD file.
