Before the disaster recovery (DR) service configuration, you need to check the application environment and storage at the production and DR ends where the protected objects reside, to ensure the normal subsequent configuration.
Oracle
Before configuring DR services, check the database environments at the production end where Oracle databases reside, and the storage environment. If any environment does not meet requirements, modify its configurations.
IBM DB2
Before configuring DR services, check the database environments at the production end where DB2 databases reside, and the storage environment. If any environment does not meet requirements, modify its configurations.
Microsoft SQL Server
Before configuring DR services, check the database environments at the production end where SQL Server databases reside, and the storage environment. If any environment does not meet requirements, modify its configurations.
VMware VMs
Before configuring DR services, check the VMware VM environment at the production end and the storage environment. If any environment does not meet requirements, modify its configurations.
