Operations
When managing OLTP applications, your most important concerns should be to:
•
Maintain a stable environment.
•
Monitor the application and system to detect potential problems. Detecting problems
early helps you maintain the high availability required by online transaction
processing. Operations staff should monitor the system whenever the application is
running. For example, if your application runs 24 hours a day, you need to establish
shifts to monitor the system 24 hours a day.
When the application is up and running (in production mode), you should not:
•
Bring down the system.
•
Change the environment.
•
Perform backups unless the application runs 24 hours a day. If the application runs
24 hours a day, perform backups during the slowest part of the day.
