Restoring RMAN Oracle 10g Backup in Oracle 11g

Question

I have the RMAN full database backup of oracle 10g (10.2.0.3) on Sun Solaris OS which I want to restore on oracle 11g (11.2.0.3) on Linux OS. The backup pieces were transferred to the oracle 11g server manually in binary mode. The Oracle 11g is installed on Linux OS. I have only the RMAN backup and no access to the primary database from where the backup has been taken.

the backup is taken in the above format. I know the ORACLE_SID and did of the database from which the backup has been taken.

whenever I tried the following command

mepc@tcstctmatson:/mepc_backup/May22fullbkp$ rman target /

the file is not corrupted as I checked the checksum on both the servers and it is the same.

Please help me how can I restore the RMAN oracle 10g backup in Oracle 11g and let me know where I am going wrong.

Thanks in advance.

Answer 1

You can not do this. AFAIK, Solaris - assuming sparc - and Linux - assuming Intel - have different endian formats and this is your problem. You could use the migrate cross platform tablespace scenario. see Oracle® Database Backup and Recovery Reference If your endian format does appear to be the same, you should convert the database using rman convert database. In that case you could restore cross platform and cross version.

Answer 2

Not applicable for 10g/11g, but this is different in 12c:

In 12c, rman offers the option following options with the backup command:

FOR TRANSPORT: This options creates a backupset which can be transported to any destination. If the destination database uses a different endian format than the source, the endian format conversion is performed on the destination database. TO PLATFORM: This option results in the endian format conversion to be performed on the source database and must be used by that supported platform only. DATAPUMP: This specifies that a data pump export dump file is created while performing a cross-platform backup. The dump file is created in s separate backup set.

Answer 3

Use below command to restore from autobackup, RMAN knows the path and it will restore.

restore controlfile from autobackup;

You need to know first Solaris to Linux are part of same endian or not. I see that Solaris 64 but and Linux 64 bit are same endian.

Even it has same endian you will see this error when " The source Production database, has a 32KB tablespace and an initialisation parameter defined for db_32k_cache_size, but the target pfile didn't have the parameter db_32k_cache_size defined"

Set in the pfile/spfile of the target db_32k_cache_size
