This section explains how to start, terminate, and monitor Oracle instances or Oracle listeners on a system that uses HA Monitor Kit. Oracle instances and Oracle listeners are managed as monitor-mode servers. Therefore, you use HA Monitor commands to start, terminate, or monitor Oracle instances or Oracle listeners.
To start or terminate an Oracle instance or Oracle listener that is running as a HA Monitor server, you must use an HA Monitor command. If you use a command other than a HA Monitor command for starting or terminating an Oracle instance or Oracle listener in a hot-standby configuration that uses HA Monitor Kit, HA Monitor may report this as an error.
To start an Oracle instance or Oracle listener, execute the monitor-mode server start command (monbegin command). This command is an HA Monitor operation command.
For details about this command, see the description under monbegin (starts a server in the monitor mode) in the manual HA Monitor (for Linux(R)).
To terminate an Oracle instance or Oracle listener, execute the monitor-mode server termination command (monend command). This command is an HA Monitor operation command. If HA Monitor Kit fails to terminate an Oracle instance or Oracle listener during a server termination process, or if an Oracle instance or Oracle listener does not terminate within the user-specified time, HA Monitor Kit forcibly terminates the Oracle instance or Oracle listener.
For details about this command, see the description under monend (terminates a server in the monitor mode) in the manual HA Monitor (for Linux(R)).
Once an Oracle instance or Oracle listener has started, HA Monitor monitors servers by executing the server monitoring command.
The server monitoring command monitors servers using the following methods:
For an overview and the operational details of the server monitoring command, see the description under Monitoring servers in the monitor mode and Controlling the server monitoring command in the manual HA Monitor (for Linux(R)).
