With the imported
restore feature, you can transfer all the data from one instance
of the database server to the same instance on a foreign host. For
example, you can back up data to ISM on one computer and restore
it to ISM on a different computer. You can perform imported restores using
either whole system (serial) or storage-space (parallel) backups.
The parallel backup must include all storage spaces and logical
logs. You must also use compatible versions of XBSA libraries
and ISM for both operations.
Important:
You cannot use a backup from one database server version
to restore on a different version. You can, however, change the database
server name in an imported restore.
The imported restore is a subset of the following three processes:
- Disaster recovery
- Database server upgrade
- Initialization of High-Availability Data Replication (HDR)
As its name implies, you can also use the imported restore solely
to complete an imported restore.
An imported restore consists of these three steps:
- Backing up the source database server to ISM
- Porting ISM to a target computer that is a different physical
host
- Restoring the data from ISM to the target database server with
the same instance on the target computer
These procedures are discussed in detail in the following sections.
Important:
The imported restore procedure is the same for both UNIX and Windows.
However, when you set the environment variables, you must use the
appropriate UNIX or Windows syntax.
