Hi Experts,
I observed strange behavior regarding oracle database services:
My setup :
Primary :NODDB : 2 node RAC 12.1.0.2
Physical Standby :NODDR : 2 node RAC 12.1.0.2
My service configuration is :
$ srvctl config service -s nodpms -d noddb
Service name: nodpms
Server pool:
Cardinality: 1
Disconnect: false
Service role: PRIMARY
Management policy: AUTOMATIC
DTP transaction: false
AQ HA notifications: true
Global: false
Commit Outcome: false
Failover type: SELECT
Failover method: BASIC
TAF failover retries: 180
TAF failover delay: 5
Connection Load Balancing Goal: LONG
Runtime Load Balancing Goal: NONE
TAF policy specification: NONE
Edition:
Pluggable database name: nodpm
Maximum lag time: ANY
SQL Translation Profile:
Retention: 86400 seconds
Replay Initiation Time: 300 seconds
Session State Consistency:
GSM Flags: 0
Service is enabled
Preferred instances: noddb1
Available instances: noddb2
So My preferred node is noddb1 and Available node is noddb2. And the role for this service is PRIMARY.
So as per my understanding this service should not be up, when datbase role is physical standby.
Now My observations are:
I Switchover to NODDR database. So NODDB will become Physical standby and nodpms service is going down automatically as expected.
Now If I will reboot NODDB-2 (which is currently in physical standby role), then nodpms service becomes online on NODDB-1 server. This is not expected behaviour of database service. Because still database NODDB is physical standby and service role is PRIMARY.
Please provide your inputs/solution on this behavior.
Thanks and Regards,
