Reply with quote

Hi,

I have 5 modules with me MOD1, MOD2, MOD3, MOD4, MOD5. all are online modules. i need the CICS region to take mod1 to mod4 from dev load lib and mod5 from PROD library while executing...

Note:
this need to be done by not deleting the MOD5 from dev load libs... if we delete the load of MOD5 from dev eventually it will take from prod only right....

is it possible ? thanks in advance....

As you've stated the problem, there is no solution. The CICS load libraries are a concatenated set of load libraries assigned to DFHRPL. Modules are retrieved from the first load library in the concatenation that contains the module. If MOD5 is in the dev load library, and the dev load library is ahead of PROD in the concatenation, all modules that are found will be used from this library. If MOD5 is in there, that version will be used. You cannot do anything to change this behavior.

The normal solution to this is to only have the required modules in the dev load library, so MOD5 would not be found there and CICS would continue going through the load libraries until it is found in PROD.

Not that I'm aware of -- first load library to contain the module in the DFHRPL concatenation list is where the module comes from.

Hi Prabakar,

The simplest solution I can think is to compile production MOD5 in dev..
This will reflect the changes done to MOD1 thru MOD4 keeping MOD5 as the production one..
Once you are done with your testing you can compile the dev version of MOD5 again..
Not sure if this is the requirement..
