Hi,
There is no script to run in order to create catalog in Oracle 8i.The thing u have to do is to execute rman and at the rman prompt enter the following command:

c:\rman target=system/system rcvcat=rman/rman

rman> create catalog; --- the create catalog command will create the rman tables and the catalog .

rman> register database --- the database of which u have to take the backup.

rman> report schema; --- check whether the information from the database whose backup is to be taken is stored in rman catalog

In case of any help please be free to ask me at [email protected]

Regards,
