Hi I followed procedure to duplicate database from 11.2.0.3.0 to 12.1.0 using RMAN.

Followed the document Oracle support Doc reference-Upgrade to 12c (12.1 /12.2) through RMAN Duplicate using BACKUP LOCATION with NOOPEN clause (Doc ID 2022820.1) as it is similar.

The duplication worked fine until the end and I followed all steps inclusing post upgrade tasks.

But now I am unable to open the database .When trying to open, it comes up with a error (I already did alter database open resetlogs upgrade and it worked but I am unable to connect to any schemas after this, as its warning I can only connect as sysdba.So I shut down the database, mounted& tried alter database open and error is coming)

Howdy, Stranger!
