HighConsumedScn
Does someone know what HighConsumedScn is? I cant find anything in metalink or google.
I'm trying to determine if is the restart scn that the applier should use to start applying.
If you start the applier u will see something like this in the alert log

For what i have seen in my lab it isnt the applied_scn nor the restart_scn. It's value is in the middle of both( applied_scn and restart_scn )

Its kind of vague, a LOGMINER message generally.
Point to an issue with your environment
This thread may help :

Capture streaming does not work after upgrade of the source database.
Hello,
We have a complex system with 2 X RAC databases 10.2.0.4 (source) and 2 X single databases (target) 11.2.0.2
Streaming is running only from source to target.
After upgrading RAC databases to 11.2.0.2 , streaming is working only from one RAC to one single database.
First RAC streaming is flowing to first single database only, and second RAC to second single only.
First source-target is streaming fine, second capture are aborted just after starting with following errors:

We have 5 streaming processes running.
When we rebuilded one of them, everything works fine, but other are too big for rebuilding.
Has anybody met with such a behaviour ?
Oracle development is already working on it but we need faster solution.
Thanks

Real-time apply cascaded logical standby database
Hi
I have a primary database orcl
Pysical standby database orcl_std
Cascaded logical standby database orcl_tri which receives archivelogs from orcl_std
Real time apply is enabled both in orcl_std (physical standby) and orcl_tri (logical standby)
When I create a table in primary orcl, I am unable to see it on orcl_tri (Although real time apply is enabled)
However, when I switch log in primary, I can see the new table on orcl_tri.
My question is, why realtime apply is not working in my scenerio ?
orcl_std : ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION USING CURRENT LOGFILE;
orcl_tri: ALTER DATABASE START LOGICAL STANDBY APPLY IMMEDIATE;
Oracle 11.2.0.3.0Hi mseberg,
Thanks for your reply.
There is no load or network issue as I`ve just created these databases for the experiement.
I have the same output from standby and primary databases.
