TimesTen: Replication Stops Working After ttRestore in 11.2.2 (Doc ID 1539886.1)

Last updated on AUGUST 23, 2021

Applies to:

Oracle TimesTen In-Memory Database - Version and later
Information in this document applies to any platform.


Customer  reports the following behavior in a primary:primary replication configuration:
ttbackup Node A
stop replication Node A (but do not drop)
stop replication Node B (but do not drop)
ttDestroy Node A; ttDestroy Node B
ttRestore Node A
start repagent on Node A
copy NodeA datastore to HostB using ttRepAdmin -duplicate
start repagent Node B
>>> now possible to replicate from NodeA to Node B, but it is not possible to replicate from NodeB back to NodeA

Customer  further states that this behavior is seen in V11.2.2, but was not encountered in V7 nor in 11.2.1.X; in these earlier releases  the procedure given above would have resulted in fully restored primary:primary replication.

This problem  and the difference in behavior relative to earlier versions - is easilly reproduced using any primary:primary replication pair.
