JMS Server Migration Issue (Doc ID 2633158.1)

Last updated on OCTOBER 13, 2021

Applies to:

Oracle Service Bus - Version and later
Information in this document applies to any platform.


User is on FMW domain which has SOA/OSB/ESS/WSM servers. An osb service which uses a durable subscribers topic and due to the singleton nature of durable subscribers topic there were no HA. Hence user configured Automatic JMS service migration on OSB cluster(2 nodes).
Auto-Migrate Exactly-Once policy is set to the migratable targets.
But the issue is, when one of the osb nodes in the cluster goes down, the whole migration process is taking more than 4 mins to complete. (for osb_server1 (migratable) to successfully activated on server osb_server2).
So for this 4 minutes there is downtime for services and they are not available. This means there is an outage no HA as promised by Oracle if we use JMS service migration.
Can this be resolved?
