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

  • 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 ?

    There is no load or network issue as I`ve just created these databases for the experiement.
