New Parm CCCHKSTP to customize CCCHK Step for CA Workload Automation ESP Edition.

Issue/Introduction

The CCCHKSTP allows the ESPCCCHK step to execute a JCL procedure that is tailored to each system. The expansion of the JCL procedure takes place at execution time on the execution system, not on the system from which a batch job is submitted. Without the CCCHKSTP parm, the ESPCCCHK step is generated programmatically and its STEPLIB is the STEPLIB concatenation of the master that submits a batch job. The master's STEPLIB concatenation might contain names of libraries that are different or don't exist on the remote system where an internodal job runs.
The CCCHKSTP command is not required if ESP Edition does not submit any internodal jobs that use CCCHK or if the STEPLIB that is generated programmatically for the ESPCCCHK step is acceptable on all remote systems where internodal jobs run.

Resolution

PTF RO26726 (for version 11.3) has introduced a new parm and OPER command - CCCHKSTP. It can be used to customize the inserted CCCHK step.

This command has the following format:

CCCHKSTP ('//ESPCCCHK EXEC procname,GROUP=')         
procname           
Specifies the name of a member containing a catalogued JCL procedure for the ESPCCCHK step. For example,      
CCCHKSTP ('//ESPCCCHK EXEC ESPCCCHK,GROUP=')        
               
A sample JCL procedure can be found in CYBESS40:          
//ESPCCCHK PROC GROUP=        
//*------------------------------------------------------------------      
//* This is the ESPCCCHK step which is inserted into each job       
//* whose definition contains one or more CCCHK statement.     
//* The name of this step must be ESPCCCHK.    
//* Change the STEPLIB statement as required.  
//*------------------------------------------------------------------      
//ESPCCCHK EXEC PGM=CYBES080,PARM='&GROUP'      
//STEPLIB DD DSN=<CAI>.SSCPLINK,DISP=SHR    
//SYSIN DD DDNAME=PARMS    
//SYSPRINT DD SYSOUT=(,)

 

Note: the &GROUP variable will be replaced with the value of ESPGROUP from the ESP that submits the job. This will require that the ESP master and proxies from both environments use same ESPGROUP value. 

If this can't be done, then you can avoid use this &GROUP variable:
#1 Set up JCL Procedure on both environments with same proc name, but different contents. For example: 
On environment #1, presume ESPGROUP is defined with value of 'prod': 
//ESPCCCHK PROC 
//ESPCCCHK EXEC PGM=CYBES080,PARM='prod' 
//STEPLIB DD DSN=<ESP.LOADLIB.PROD,DISP=SHR 
//SYSIN DD DDNAME=PARMS 
//SYSPRINT DD SYSOUT=(,) 

On environment #2, presume ESPGROUP is defined with value of 'nonprod': 
//ESPCCCHK PROC 
//ESPCCCHK EXEC PGM=CYBES080,PARM='nonprod' 
//STEPLIB DD DSN=<ESP.LOADLIB.NONPROD,DISP=SHR 
//SYSIN DD DDNAME=PARMS 
//SYSPRINT DD SYSOUT=(,) 

#2 In ESPPARM for ESP master and proxies of both non-prod and prod environments, add following: 
CCCHKSTP ('//ESPCCCHK EXEC ESPCCCHK') 

With above settings, when ESP master on non-prod environment submits the internodal job A, the step below is added before it's sent to JES: 
//ESPCCCHK EXEC ESPCCCHK 

But the JCL Proc ESPCCCHK won't be expanded until the job A is on the execution system on prod environment, so it will be expanded as below: 
//ESPCCCHK PROC 
//ESPCCCHK EXEC PGM=CYBES080,PARM='prod' 
//STEPLIB DD DSN=<ESP.LOADLIB.PROD,DISP=SHR 
//SYSIN DD DDNAME=PARMS 
//SYSPRINT DD SYSOUT=(,) 

And for normal jobs that run on non-prod systems, ESPCCCHK Proc will be expanded to following: 
//ESPCCCHK PROC 
//ESPCCCHK EXEC PGM=CYBES080,PARM='nonprod' 
//STEPLIB DD DSN=<ESP.LOADLIB.NONPROD,DISP=SHR 
//SYSIN DD DDNAME=PARMS 
//SYSPRINT DD SYSOUT=(,) 
 

Additional Information

GROUP
The GROUP parameter, of the ESPCCCHK step, corresponds to the value of the ESPGROUP initialization parameter. ESP inserts it automatically at job submission time. If the ESPGROUP initialization parameter is omitted, the default group name is the ESP subsys name. A master and its proxies must have the same ESPGROUP value. If a master submits an internodal job containing an ESPCCCHK step, the ESP Master and proxies on the remote system must have the same ESPGROUP value.
