Recovery to a time before the last resetlog issue

Question

Hi experts!
Env: 11.2.0.2 including a 11.2.0.2 RMAN recovery catalog.
Having big trouble understanding what is happening here.. I'm trying to return my database to a time before the last resetlogs time, but cannot as RMAN always gives "RMAN-20011: target database incarnation is not current in recovery catalog". And yes, I've reset database to previous incarnation.

Also I notice in the alert log during "searching for all files in the recovery area.."

Setting recovery target incarnation to 9
Setting recovery target incarnation to 9It seems to me that RMAN "ups" the incarnation back to the CURRENT one (the one before I ran reset incarnation command).
But why?
I'm obviously doing something wrong here, please shed some expert enlightment.
Thanks!

Answer 1

Hello;
Been awhile, probably time for me to test this again. Here's what I think :
The database with the DBID (1659522178) and DBINC_KEY (521) has to be reset in the recovery catalog and re-registered for its backups to resume.
RMAN> reset database to incarnation 521;
database reset to incarnation 521
RMAN> register database;In my way old notes I do :
RMAN> connect target sys/sys
RMAN> startup nomount
RMAN> restore controlfile from'....
RMAN> Alter database mount
RMAN> reset database to incarnationSo use target database controlfile instead of recovery catalog
Best Regards
