Setting up and starting the communication server

About this task

This topic describes how you setup, start, and run a CICS BAC communication server. It provides the sample JCL that you can use and information about the data sets and parameters used by the communication server. Figure 1 contains an example of the JCL you use to submit the communication server as an MVS™ started task.

Note that you need a communication server only if you plan to use the CICS BAC workstation administration client. If you perform all administration tasks by using either the ISPF administration interface or the file maintenance utility, you do not need a CICS BAC communication server.

Figure 1. CICS BAC communication server sample startup procedure
//CBKCSRVR  PROC
//CBKCSRVR EXEC PGM=CBKSMAIN,REGION=0M
//STEPLIB  DD DISP=SHR,DSN=hlq.SCBKLOAD
//         DD DISP=SHR,DSN=hlq.SDFHEXCI
//CBKPARMS DD DISP=SHR,DSN=hlq.CBKPARMS
//SYSABEND DD SYSOUT=*
//*************************************************** 
//* Un-comment the following DD statement if you need 
//* to add a SYSMDUMP DD statement. You might need to 
//* modify this statement to meet your installation’s 
//* requirements.                                     
//*************************************************** 
//*SYSMDUMP  DD DISP=(,CATLG),DSN=hlq.sysmdump.dataset,
//*          UNIT=SYSDA,SPACE=(CYL,(50,25)), 
//*          DCB=(DSORG=PS,RECFM=FBS,LRECL=4160, 
//*          BLKSIZE=24960 
Note:
  1. Change the characters hlq to the high-level qualifiers you specified for these data sets:
    • SCBKLOAD is the name of the CICS BAC load library
    • SDFHEXCI is the name of the CICS® TS EXCI load library
    • CBKPARMS is the name of your CICS BAC parmlib.
  2. Also change hlq.sysmdump.dataset to the name of your own dump data set.
  3. When you have customized CBKCSRVR, add the procedure SYS1.PROCLIB or another suitable procedure library,
  4. If you put the CBKCFTBL member and the optional CBKSRVR parameter member in the MVS logical parmlib concatenation, authorize the communication server task to have READ access to all the data sets in the MVS logical parmlib concatenation. The communication server searches for CBKCFTBL and CBKSRVR in the logical parmlib concatenation if either of these members is not found in the CBKPARMS data set.
