Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of z/OS Management Facility        *
  *                 Classic Interface and users of the CEA TSO/E *
  *                 Address Space Manager API at HBB7780.        *
  ****************************************************************
  * PROBLEM DESCRIPTION: Provide reconnect ability for those     *
  *                      TSO/E sessions managed by CEA.          *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  This support should reduce CPU costs for an installation which
  uses Z/OSMF Classic ISPF or the CEA Address Space Manager API by
  saving CEA managed TSO/E address spaces for a configurable
  period of time and reconnecting to them for new requests by the
  same userid.  The support is performed by the system and is
  managed for all users through a new CEA parmlib statement.  (By
  default, this support is turned off.)  When a new TSO/E session
  is requested and if there is an existing session saved for that
  userid with the same TSO/E session parameters, that session is
  reconnected for the user thus avoiding overhead related to
  obtaining a new address space and much of the overhead related
  to logging on to a TSO/E session.
