z/OS Communications Server persistent sessions support

This diagnosis information describes in detail how CICS® handles z/OS® Communications Server persistent sessions support. When persistent sessions support is exploited by a CICS region, sessions can be recovered if CICS, z/OS Communications Server, or z/OS fails, depending on the type of support.

For information about sessions and recovery, see Situations in which sessions are not reestablished and Situations in which the z/OS Communications Server does not retain sessions.
