Can a cobol program be 'ATTACH'ed as a sub-task of an assembler program? The environment is Z/OS with IBM Enterprise COBOL for z/OS 3.3.1. If so, are there considerations I need to take at the Root Task level to establish the LE environment? Or, conversely, if the environment is established at the root level, will it be used by the attached (sub-task) COBOL program or will another environment be set up for each subtask?

The proposed application is an MQ listener triggering multiple COBOL programs which invoke DB2 Stored procedures. The objective is to achieve parallelism to DB2 in order to retrieve the required data in the shortest amount of time. Retrievals can be for 10K to 100K (or more) rows at a time.

Thanks

PS: We're running on 2 dedicated T-REXs with 4 processor engines each and 23 Gig of memory. The Database in question has 25+ billion rows and grows at 500 million rows weekly.

PSS: I know there is a DB2 listener in DB2 V8, but we are V7 with no plans to install the listener APAR until August (at the earliest) which is after our project deadline.
