12.1 Step 1: Configuring Sub-transactions on Z/OS

You can configure sub-transactions on z/OS in the zostrans.desc file at $ART_IMS_CONFIG, all of which must only be called sub-transaction. For instance, in the following listing:

Listing Sample Sub-transaction Configuration

[zostran] 
NAME=SUBTRAN1 
CONV=TMAA2Z 
[zostran]
NAME=SUBTRAN2

NAME is the z/OS transaction name. CONV is the input message’s buffer converter program, which can be generated by the ART Workbench based on a copybook describing the input message/segment structure of the sub-transaction.

Note:

CONV handles the data conversion before calling sub-transactions on z/OS. If it is not specified, ART/IMS only does ASCII to EBCDIC conversion by default, for example, treating all bytes in the input message as characters
