Disaster recovery deployment architecture (Oracle)

Primary and recovery BMC TrueSight Infrastructure Management Servers

The recovery BMC TrueSight Infrastructure Management Server is the backup server for the primary BMC TrueSight Infrastructure Management Server and must be up when the primary BMC TrueSight Infrastructure Management Server fails. Both the servers must have the following configuration with Infrastructure Management Performance Management installed:

• Identical operating system version
• Identical hardware configuration
• Located in the same domain
• Configured logical fully qualified domain names
• Identical time zone, location, and language settings

Primary and recovery database servers

The primary and recovery database servers must run on the same operating system. They must run Oracle Database in ARCHIVELOG mode. They must have the same hardware and software configurations. The database servers and their corresponding BMC TrueSight Infrastructure Management Servers must be on the same subnet.

Database replication solution

A database replication solution keeps the data in the recovery database in sync with the primary database.

If you do not have a database replication solution, you can also use a database replication tool to back up the database files and then transfer the files to the recovery database server. The database replication solution helps reduce system down time when compared to the manual backup process.

Storage replication solution

A storage replication solution automatically backs up the configuration files at frequent intervals even when the primary BMC TrueSight Infrastructure Management Server is up and running.

The backed-up files are critical to bring up the recovery BMC TrueSight Infrastructure Management Server at the time of a disaster.

If you do not have a storage replication solution, you can also manually back up these files. The storage replication solution helps reduce system down time when compared to the manual backup process.

DNS server

The DNS server resolves to the recovery BMC TrueSight Infrastructure Management Server at the time of a disaster so that the monitoring of the devices and data collection continue to function normally.
