unique ETID (termid) for basic CICS COBOL access to ADABAS

Are there any examples or samples of generating a unique ETID/termid for so called Batch interfaces like WebSphere/CTG using EXCI to call a COBOL program that then executes ADABAS database calls. Currently the same termid/facility id for the zWAS/CTG interface is causing issues with ET calls getting 144/145 error codes… thinking the call is coming from the same terminal id.
