Need to modify jobcards related to the Db2 system

Our special challenge:

We are using the SCHENV parameter in the JCL to route the job to the right LPAR.

Currently we include a note in the jobcards and every user has to change the variable:

==MSG> DB2 Admin: EDIT generated JCL 
==MSG> 
000001 //#‌#‌#‌#‌#‌#‌#‌ JOB (3WIR001,000,00,'DB2 ADMIN DB2'), 
000002 // ' ',NOTIFY=&SYSUID, 
000003 // MSGCLASS=R,PRTY=5,TIME=(0030), 
000004 // CLASS=A,SCHENV=DB2X <== !!! SET TARGET DB2 !!! 

In Db2 Admin it is possible to generate jobs for all remote reachable Db2 systems.

So the SCHENV=DB2x has to be set dynamically to the right variable.

Examples:

run DB2ADMIN on TSO with local DB2A

1)

generated JCL >> SCHENV=DB2A

>> this will be ok with the suggestion

2)

connect to DB2B (same node/sysplex)

generated JCL >> SCHENV=DB2B

3)

connect to DB2T (other node/sysplex T)

generated JCL >> additional XMIT to NODE T:

first jobcards should use SCHENV=DB2A (local Db2)

then following jobcards after XMIT NODE T should use SCHENV=DB2T
