When you take the database server from offline to microkernel mode, the database server is available to perform a cold restore of all stored data from a level-0 backup. To take the database server from offline mode to microkernel mode for a cold restore, execute the following command:
xctl -C oninit -m
To verify that the database server is running, execute xctl onstat from the command line. The header on the onstat output displays the current operating mode.
