Cause

RMAN Duplicate command is trying to open the block change tracking file from Prod database which is of course not available and should not be available

Solution:

The bug is described in oracle note Doc ID 1098638.1. Although the note says that the bug is fixed in 12.1, I have issue even in version 12.1

Include SET NEWNAME FOR BLOCK CHANGE TRACKING FILE in your RMAN duplicate script as shown below and re-run the duplicate

run
{
SET NEWNAME FOR BLOCK CHANGE TRACKING FILE TO '/oracle/oradata/TESTDB/block_change.bct';
...

duplicate database PRODDB DBID 395734896 to TESTDB...;
}

OR if you are using ASM

run
{
SET NEWNAME FOR BLOCK CHANGE TRACKING FILE TO '+DATA';
...
duplicate database PRODDB DBID 395734896 to TESTDB...;

...........

}

If you are lucky the solution above may work for you but It really did not worked for me.

Solution That Worked For Me
Disable the Block Change Tracking in auxiliary database (ie in the duplicated database) as soon as it is mounted
Triggered the clean duplicate
Waited for the controlfile to be restored and Auxiliary database got mounted.
disabled the block change tracking in auxiliary database (ie in the duplicated database) as soon as it is mounted

SQL> alter database disable block change tracking;

Database altered.

SQL> select * from v$block_change_tracking;

STATUS FILENAME BYTES CON_ID
------------------------------ ---------- ---------- ----------
DISABLED

Please write in the comment if the solution worked for you as well

How to Switch Log File from All Instances in RAC

<<Back to Oracle RAC Main Page Switch The Log File of All Instances in Oracle RAC. In many cases you need to switch the logfile of the database. You can switch logfile using alter system switch logfile command but if you want to switch the logfile from all the instances you need to execute the command on all the instances individually and therefore you must login on all the instances. You can avoid this and switch logfile of all instances by just running the below command from any of the instance in RAC database SQL> ALTER SYSTEM SWITCH ALL LOGFILE; System altered.

Note: Oracle does not recommend deleting keystore file (ewallet.p12) that belongs to a database. If you have multiple keystores, you can choose to merge them rather than deleting either of them.
