IBM Tivoli Composite Application Manager for Applications, Version 7.2.1

Installation and configuration considerations

The Oracle Database Extended agent supports local monitoring and remote monitoring.

Differences between local and remote monitoring

Table 1 contains a comparison of the two different ways of monitoring.

Table 1. Comparison of local and remote monitoring
Feature	Local	Remote
Installation on Oracle Server computer	Yes	No
Oracle physical disk usage monitoring	Yes	Not supported
Oracle alert log monitoring	Yes	Yes, requires mounting the log directory for the remote computer to a local computer, and requires specifying the mount path at agent configuration.
Other monitoring features	Yes	Yes
Maintenance effort	A large effort requires applying an agent patch on each Oracle server computer.	A small effort requires applying a patch on the computer on which the agent is installed one time.

Best practice: number of agent instances and database connections on one system

The best practice involves considering the number of agent instances and database connections on one system. 10 agent instances times five database connections (monitoring 50 databases on one system) is optimal. The performance of the agent depends on system performance, network performance, and most importantly the number of data requests, including situation and historical data collection. With fewer data requests for one database, more databases can be monitored on one system. As a best practice, first configure 10 agent instances times five database connections, and observe performance, such as the length of the response time for the data request. If the performance is acceptable, you can consider monitoring more databases on the system; if not acceptable, set up another system with the Oracle Database Extended agent installed.

Installation considerations on Windows systems

Launch installer setup.exe as Administrator role

To run the installer in the Administrator role, in the Documents library window, right-click the setup.exe file and select Run as administrator (Figure 1).
