Problem

Once Partner CA certificates (RootCA/IntermediateCA) have expired, they need to be removed from TSIM CertificateManager (CA certificates Tab).

New CA certificates need to be imported in the same location.

OFTP connection does not work and throws a NPE error, after importing the new CA certificates (and after waiting 5 minutes for the new certificates to be updated in the Integration Server):

Resolution

A workaround solution for this behavior is to restart both AJAS (ajas stop/ajas start) and IS (is stopall/is startall) components in TSIM.

The root cause analysis will be performed and if a proper solution is found, the article will be updated.
