In the previous blog, we saw Steps to create a Heterogeneous Dataguard between Windows and Linux Click here to read more. In this blog, we are going to perform a clone of Windows Oracle DB by taking RMAN backup and restoring it to Oracle Linux Server.
To view, the full log the below demo Click here.
Below are the high-level steps we will follow to configure Clone
1. Take Source DB backup from Window Server
2. Transfer backups to Linux Server
3. Prepare Oracle Instance in Linux
4. Initiate restore command in Linux server
5. Verify Clone DB
6. Re-create controlfile
7. Perform manual recovery
Below are setup details and the same will be used in this demonstration.
| OS | Hostname | Datafile Location | Logfile Location | Role | DB Name |
| 1 | test-machine01 | G:UCASNEWUCASNEW , H:UCASNEWORADATA_2 | G:UCASNEWORADATA_1 , H:UCASNEWORADATA_1 | Source | ucas |
| 2 | test-machine02 | /data01/oradata_2/ , /data02/oradata_2/ | /data01/oradata_1/ , /data02/oradata_1/ | Clone | ucas |
Step 1. Take Source DB backup from Window Server: Take RMAN Full backup of source windows database including datafiles, archivelog files, and controlfiles.

Step 2. Transfer backups to Linux Server: Once all backups are done. Transfer all backups to Linux Server. We are using here pscp.exe tool to transfer backup files from Windows to Linux Server. Please note we are transferring DB backups to the Linux Server location: /u01/db_pump.

Step 3. Prepare Oracle Instance in Linux: Create clone DB init parameter file, password file, and static listener configuration. When you are going to use RMAN duplicate command to perform a clone. RMAN duplicate command requires static listener configuration in a “listener.ora” file. Make sure you set proper log_file_name_convert & db_file_name_convert parameter.

RMAN command failed at recovery with ORA-00600. From the above output you will notice restore was successful but during the recovery, the process job failed. Below is Oracle Support Note.
Redo application is not supported between Linux and Windows except with a standby database. This means that the backup must be a cold (consistent) backup, which requires no redo application. If redo apply is required to recover the database on the new platform it will fail. Using consistent (cold) backup method should be used for duplicating cross-platform.
Step 5. Verify Clone DB: At this stage, we are unable to open DB with resetlogs option due to the error “ORA-19838: Cannot use this control file to open database” as controlfile type is BACKUP.

Step 7. Perform Manual Recovery: Even manual recovery is failing with same ORA-00600 error. Since there is no way to perform recovery we will use Oracle undocumented parameter “_allow_resetlogs_corruption” to open the database. To use this parameter we need to set undo_management parameter to manual.
