Recovery after a restart of CICS

Important

Information in this chapter about the EPI and the Client terminal emulator function applies to:

This chapter describes how users of attached Client workstations are affected if CICS on System/390® is restarted.

After a restart of CICS on System/390, Start of changeAPPCEnd of change sessions to CICS Clients are recovered automatically.

Note:
If CICS on System/390 is using VTAM® persistent sessions support, VTAM holds on to the sessions to the Client until the restart occurs; they are then unbound by CICS. (Using persistent sessions causes a restart to take slightly longer than it otherwise would.)

There are some restrictions on the use of persistent sessions with CICS Clients--see Restrictions on Client support.

Start of changeFor TCP/IP connected Clients, when CICS restarts after a failure it has no knowledge of any Clients that may have been installed. The Clients must be re-installed.End of change
