Resolution:
There is an SDK-specified syntax for connecting to the Repository with non-default RV parameters:

The next example shows a connection string to an adapter instance description defined in a remote repository that uses the given subject name for discovery. There are no spaces in the subject string.

-system:repourl tibcr://ZAPInstance1:subject=foo.bar: service=7500:network=le0:daemon=tcp:target:7500:timeout=120

In this example subject is the subject to use for repository discovery. service, network, and daemon are TIB/Rendezvous parameters. “timeout” is the time out value in seconds for any TIB/Repository communication to be aborted.

If repositoryLocalFile is specified, a connection is made to a local file repository. For example, the following command-line argument connects to a repository instance named ZAP.DAT that is on the local file system.

-system:repourl C:\repositories\ZAP.DAT

-system:instanceid instanceId
