About this task

The database server has various Database server operating modes.

You can use the onstat - command to determine the database server mode.
You can use the onmode utility to switch the database server from one mode to another.

Use the procedure for your operating system:

Stopping and starting the database server (UNIX, Linux, Mac OS X)

Stopping and starting the database server (UNIX™, Linux™, Mac OS X)

You run the onmode utility to stop the database server, and the oninit utility to start the database server.

Procedure

To stop the database server, run the onmode -ku command.
To start the database server, run the oninit command.
You can include options to the oninit command. For example, you suppress verification prompts by running the oninit -y command.
