IMS Connect

IMS Connect executes IMS transactions. It is the route used by Test Transaction, Populate from IMS, and published IMS System APIs.

Browse

Open IMS → Browse to see associations already stored for this host’s IMS catalog. Filter entries, open source members, delete associations, or select a row to open Test Transaction with that transaction and source pre-loaded. Publish or unpublish from catalog surfaces to gate public API exposure.

Test Transaction

Enter a transaction code (optional, max 8) and edit the message in the hex editor. The workbench sends trancode and dataHex, not a structured JSON payload. After Populate from IMS, a Browse row opens this page with that transaction and source already loaded.

Published IMS APIs use a different contract: POST /api/v1/{catalogId}/{endpointName}/{targetName} accepts the copybook fields as a JSON body (the transaction code is the path target).

Populate from IMS

Use Populate from IMS on Browse to list transactions through Operations Manager (QUERY TRAN), match COBOL source, and add selected transactions to the catalog. The host needs IMS Connect plus RSE (for the CSLUSPOC job). Without RSE, the button stays disabled; one-off Test Transaction still works.
