Streams Propagation Process : Ora 12154 After Reboot with Transparent Application Failover TAF configured
Last updated on SEPTEMBER 07, 2015
Applies to:Oracle Database - Enterprise Edition - Version 126.96.36.199 and later
Information in this document applies to any platform.
With a Streams configuration that works fine, replication is working both
ways. Transparent Application Failover (TAF) is also configured.
The DBLink setup for the propagation of the messages points to an entry in the tnsnames.ora which is configured for TAF.
After a server reboot, a ORA-12154 TNS:could not resolve service name appears in the LAST_ERROR_MSG of DBA_QUEUE_SCHEDULES view. After the 16 failures, the propagation process fails (this is normal).
