The following commands control the CICS sockets interface:
EZAC for configuration
EZAO for control
Use EZAC to configure listeners. Each listener is identified by its transaction ID. The following example shows the output of the EZAC,DISplay,LISTENER command:
APPLID ===> CICSDEV1 APPLID of CICS System TRANID ===> SY01 Transaction Name of Listener PORT ===> 03044 Port Number of Listener AF ===> INET Listener Address Family IMMEDIATE ===> NO Immediate Startup Yes|No BACKLOG ===> 020 Backlog Value for Listener NUMSOCK ===> 100 Number of Sockets in Listener ACCTIME ===> 060 Timeout Value for ACCEPT GIVTIME ===> 000 Timeout Value for GIVESOCKET REATIME ===> 000 Timeout Value for READ MINMSGL ===> 004 Minimum Message Length TRANTRN ===> YES Translate TRNID Yes|No TRANUSR ===> YES Translate User Data Yes|No SECEXIT ===> SYBTPSCY Name of Security Exit GETTID ===> NO Get AT-TLS ID (YES|NO) USERID ===> DFHCICS Listener User ID WLM group 1 ===> Workload Manager Group Name 1 WLM group 2 ===> Workload Manager Group Name 2 WLM group 3 ===> Workload Manager Group Name 3
Use the EZAO command to start or stop the entire sockets interface for the region, or to start and stop individual listeners.
If you want the CICS sockets interface to start automatically when CICS is initialized, you must add the EZACIC20 program to the second stage of the start-up PLT and the first stage of the shutdown PLT. Any sockets defined with IMMEDIATE=YES are automatically started.
The CICS sockets interface creates the required work areas for each listener only at start-up. If a listener is created while the interface is running, the interface must be stopped and restarted using EZAO STOP CICS and EZAO START CICS. If not, the Sybase listener ends abnormally with code SB01, indicating that the required work area does not exist. Changes to existing listeners (such as port numbers, backlog, and so on) require only stopping and starting that listener using EZAO STOP LIST(SYxx) and EZAO START LIST(SYxx).For detailed information about the EZAC and EZAO commands, see the z/OS Communications Server: IP CICS Sockets Guide.
