Optional: Customizing a CEA scheduler address space JCL (CEASCHED)

A z/Server CEA scheduler task CEASCHED provides the services to start and communicate with a CEA-launched TSO user address space. The communication is handled using a z/OS USS message queue.

Customize the sample hlq.ZSERVER.JCL(CEASCHED) and copy it to the PROCLIB concatenation and named as ceasched.

Verify and customize the high level qualifier defined for TAURHLQ, and also TCPDATA to make sure it specifies the correct TCPIP configuration data set:

//TAURCEA  PROC 
//TAURHLQ  SET  TAURHLQ=HLQ.ZSERVER 
//TCPDATA  SET  TCPDATA=TCPIP.TCPDATA
//IVPISPF  EXEC PGM=IKJEFT01,PARM='TAURIP', 
//       DYNAMNBR=200,REGION=0M,TIME=NOLIMIT 
//STEPLIB  DD  DISP=SHR,DSN=&TAURHLQ..LOADLIB 
//SYSPRINT DD  SYSOUT=*,DSN=&&SYSPRINT 
//SYSTSPRT DD  SYSOUT=*,DSN=&&SYSTSPRT 
//ZCOTSPRT DD  SYSOUT=*,DSN=&&SYSTSPRT 
//ZCOTSIN  DD  DUMMY 
//SYSTSIN  DD  DUMMY 
//*IPCONFIG DD  DISP=SHR,DSN=&TAURHLQ..CONFIG(CEASCHED)
//READER   DD  SYSOUT=(*,INTRDR) 
//SYSEXEC  DD  DISP=SHR,DSN=&TAURHLQ..EXEC 
//         DD  DISP=SHR,DSN=&TAURHLQ..REXX
//SYSTCPD  DD  DISP=SHR,DSN=&TCPDATA
//         PEND

The SYSTCPD DD statement has been added to provide information about the IP stack on your host to the started task.
