  The DSA storage for each exit is obtained by EVEPYINI which
  disables and/or enables the CICS user exits. However, the
  program obtains one area only which does not allow to run a
  single exit concurrently.
  

Problem conclusion

• The DSA storage is now obtained only once by the prolog code of
  the exit routine and chained to a list in the global work area
  which belongs to each exit. If the exit is scheduled
  concurrently then a new DSA is allocated and chained to the list
  as well. This will allocate not more storage areas than CICS
  schedules an exit concurrently. The storage areas are released
  by the system when CICS terminates or by the transaction SARL
  which is invoked whenever policy data must be refreshed.
