RMAN ORA-19698: file is from different database

Oracle Tips by Donald BurlesonMay 2, 2017

Question: I am getting the ORA-19698 error using an RMAN restore:

I'm trying to recover the database after restoring the database from hot backup, error message is getting like this:

ora-19698: /u01/oradata/redo01.log is from different database:

Answer:  The oerr utility shows this for the ORA-19698 error:

ORA-19698: %s is from different database: id=%s, db_name=%s

*Cause: Catalog failed because the database id in file header
does not match the one in control file.

*Action: Supply the correct file belonging to this database.

Note: It this was a cold backup, do not use the RMAN RECOVER command!

Simply issue the ALTER DATABASE OPEN RESETLOGS command;

If the error "ORA-19698: %s is from different database" is seen during an Oracle disaster recovery operation, perform the following:

1. Bring the database to nomount state (Steps mentioned below):

At a command prompt, type the following command: SQLplus / as SYSDBA

type shutdown immediate;

type startup nomount;

2. Empty the contents of the directory (under the oradata directory) containing the data files and online redo logs of the newly created database.

3. Re-try the control file restore operation.
