Disaster recovery deployment architecture (Oracle)
The architecture of the disaster recovery system varies according to the database you use. If you are using SAP SQL Anywhere, see Disaster recovery deployment architecture (SAP SQL Anywhere).
This overview presents the following topics:
Disaster recovery system architecture for TrueSight Infrastructure Management
The disaster recovery system consists of two TrueSight Infrastructure Management Servers, a primary server and a recovery server. They are connected to separate database servers that run Oracle Database. During a disaster, the DNS alias name resolves to the recovery TrueSight Infrastructure Management Server so that data and service availability are continued.
Components of TrueSight Infrastructure Management disaster recovery system
| Component | Description |
|---|---|
Primary and recovery TrueSight Infrastructure Management Servers | The recovery TrueSight Infrastructure Management Server is the backup server for the primary TrueSight Infrastructure Management Server and must be up when the primary TrueSight Infrastructure Management Server fails. Both the servers must have the following configuration with Infrastructure Management Performance Management installed:
|
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 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. Note Check with your Oracle Database administrator for the appropriate database replication solution or tool. You must use an Oracle-certified database replication solution or tool. |
Storage replication solution | A storage replication solution automatically backs up the configuration files at frequent intervals even when the primary TrueSight Infrastructure Management Server is up and running. The backed-up files are critical to bring up the recovery 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. Note Check with your IT administrator for the appropriate storage replication solution. |
DNS server | The DNS server resolves to the recovery TrueSight Infrastructure Management Server at the time of a disaster so that the monitoring of the devices and data collection continue to function normally. |
