HOW TO DUPLICATE A 11gR2 INSTANCE USING RMAN AND ACTIVE DATABASE Platform: Oracle Version: Source server: Target server:

Windows/Linux 11.2.0.2.0 ap2-ora01.ap2.ap2.se rs-ora01.ap2.ap2.se

I start with a standard database created by dbca, i called the db MJ and I will create a copy on another server named VJ. We start on the server where the copy (VJ) should go: Create tns alias for both instances MJ and VJ, in 11g you cannot use connect / anymore. You have to connect both to target and auxiliary using a tns alias. I’m using net configuration assistant to create mine. When they are created edit the tnsnames.ora file and add (UR=A) for the VJ entry So it looks like this. VJ = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = rs-ora01.ap2.ap2.se)(PORT = 1521)) ) (CONNECT_DATA = (UR=A) (SERVICE_NAME = VJ) ) ) You can use tnsping to verify the names E:\app\oracle\product\11.2.0\dbhome_1\database>tnsping mj TNS Ping Utility for 64-bit Windows: Version 11.2.0.2.0 - Production on 05-JAN-2011 14:05:25 Copyright (c) 1997, 2010, Oracle.

Now we should create a static entry in the listener for instance VJ, use net manager to do that. You can do both the tns alias and static entry by manually edit the tnsnames.ora and listener.ora file. Be careful if you do that, it can easily become an invalid entry. I recommend using the tools.

After you have saved and exit net manager you have to reload the listener to register the instanses. Lsnrctl reload, verify it by issue lsnrctl status C:\Windows\system32>lsnrctl reload LSNRCTL for 64-bit Windows: Version 11.2.0.2.0 - Production on 07-JAN-2011 15:20:23 Copyright (c) 1991, 2010, Oracle.

create a init.ora file, name = initvj.ora it has one row only: db_name=vj Copy the password file PWDMJ.ora from the source db and rename it to PWDVJ.ora. You should be able to create a new password file using orapwd and using the same password creating the MJ instance. I had issues with ORA-01017, invalid password which was solved when copying the file from the source server. If you are on linux and wants to create a password file run: Orapwd filename=orapw password=kalle If you are on windows the password file is created when creating the service

This step is only needed if you run on Windows: Create a service using oradim, some examples have -intpwd this creates the passwordfile since we copy ours I omit -intpwd oradim -new -sid VJ [-intpwd kalle] -startmode AUTO Confirm that your service exists

Now let’s move to the source server If you perform all the duplicate actions from the target server you can omit these steps. Create tns alias for both instances MJ and VJ. I’m uisng net configuration assistant to create mine. When they are created edit the tnsnames.ora file and add (UR=A) for the VJ entry so it looks like this. VJ = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = rs-ora01.ap2.ap2.se)(PORT = 1521)) ) (CONNECT_DATA = (UR=A) (SERVICE_NAME = VJ) ) ) You can use tnsping to verify the names C:\Windows\system32>tnsping mj TNS Ping Utility for 64-bit Windows: Version 11.2.0.2.0 - Production on 05-JAN-2011 14:19:42 Copyright (c) 1997, 2010, Oracle.

Now let’s start the duplicate Go to the target server and start RMAN and connect to both instances, make sure you use the alias you created before. You are not allowed to connect using / as in previous releases. If you do that the duplicate will fail!!!! I tested to run the duplicate script from the source server, it ended up with a crash. I tested again and ran it from the target server and it worked. You should be able to run it from any server but if you have issues, try to run it from the target server and see if it works.

NOTE: I experienced ORA-12514 when I ran the duplicate script. This was seen because the instance VJ was not statically registered with the listener on the target server. Use lsnrctl status to verify that the instance is listed even if it is down. If you analyze the output from the duplicate you will find RMAN-07526: Reason: File is not an Oracle Managed File

It seems to be known why we see it, google the errorcode or look into oracle support. It isn’t an issue with the clone.
