Both Managed Servers in Active State at Same Time after Full GC Exceeds Heartbeat Timeout
(Doc ID 2170005.1)
Last updated on MAY 15, 2023
Applies to:
Oracle SOA Suite - Version 11.1.1.7.0 to 12.1.3.0.0 [Release 11gR1 to 12c]Information in this document applies to any platform.
Symptoms
On : 11.1.1.7.0 version, Health Care FastPath
ACTUAL BEHAVIOR
---------------
When a manually triggered full garbage collection on managed server MS01 (passive) takes over 100 seconds, this forces a switch from server MS02 (active) to MS01. Yet after garbage collection completes the source endpoints are no longer receiving messages.
B2B_HA_REGISTRY table still shows that MS02 is ACTIVE but logs suggests that the active server has become MS01.
EXPECTED BEHAVIOR
-----------------------
The active managed server should not be switched to passive since the missed heartbeat actually occurred on the passive managed server.
STEPS
-----------------------
The issue can be reproduced at will with the following steps:
1. Run full garbage collection on MS01 that takes longer than the heartbeat timeout.
2. Active state switches to MS01.
