When you create an IMP, EXP, or VSM table in the TIBCO Object Service Broker UI, you can use a copybook as the source for its definition using Data Discovery.
TIBCO Object Service Broker can monitor changes to the copybook from the TIBCO Object Service Broker UI if the source is a member of a PDS. To do so, set the Monitor flag for the table. To check for changes on all monitored tables, run the Change Tracking Agent. Each table is also checked when the definition is viewed in the TIBCO Object Service Broker UI.
Member CTA of the JCL data set contains JCL to run the Change Tracking Agent in Batch mode. When you run the Agent, it checks the copybooks that were used to create the tables in your TIBCO Object Service Broker system that have the Monitor flag set. This job must be run from a TIBCO Object Service Broker level‑7 user id.
The Change Tracking Agent then indicates (with the “TIMESTAMPS DIFFERENT” message) that changes were made to the copybook since the last time the member statistics were updated for the table. Also, the next time you view the definition of the table in the TIBCO Object Service Broker UI, you see a message telling you that the definition is out of sync with the copybook. To remove this message, save the table (with or without changes) in the TIBCO Object Service Broker UI and confirm the request to reset this message.
