This video introduces refresh agents command in PAS for OpenEdge to terminate all sessions within a multi-session agent so that updates to an ABL application can be made in real-time. The refresh agents feature is available as a TCMAN command as well as a REST and JMX API.

The refresh agents feature allows online schema updates to an application which provides high availability for a PAS for OpenEdge instance. The command may also improve memory leaks in an ABL application.

Warning: Do not use the refresh task while the PAS instance is serving active requests or has stuck or busy sessions. refresh unconditionally terminates all ABL sessions in the MS Agent immediately—any in-progress requests could be cut without a graceful drain, which can result in data loss, transaction rollbacks, or corrupted client state. This task is intended for code deployment during a scheduled quiet period when no user activity is expected. Before using refresh, run the trim tasks above to gracefully terminate any active or lingering sessions.
