Database Reference
In-Depth Information
A large amount of the time required to complete the migration will be
spent writing files, with RMAN converting files and transferring files from
the source to the destination. If you have a time constraint, consider manu-
ally copying files across a LAN instead; utilize your storage area network
(SAN)-attached storage, network attached storage (NAS), or network file
system (NFS)-mounted file systems to speed the process. Allowing source
and destination to share the staging area will reduce your transfer time.
Also consider running the RMAN CONVERT process on the system that has
the better throughput.
Step 1: Check the Prerequisites
Before you begin TDB, you'll need to verify that your source and destination database plat-
forms are supported. From your source database, query the V$DB_TRANSPORTABLE_PLATFORM
view. If you don't see the destination platform, you'll need to skip TDB and choose another
migration method.
