FULL_DISK_INIT configuration parameter

Use the FULL_DISK_INIT configuration parameter to prevent an accidental disk reinitialization of an existing database server instance. This configuration parameter specifies whether or not the disk initialization command (oninit -i) can run on your HCL OneDB™ instance when a page zero exists at the root path location, which is at the first page of the first chunk location.

onconfig.std value
FULL_DISK_INIT 0
values
0 = The oninit -i command runs only if there is not a page zero at the root path location.

1 = The oninit -i command runs under all circumstances, but also resets the FULL_DISK_INIT configuration parameter to 0 after the disk initialization.

takes effect
After you edit your onconfig file and restart the database server.

Usage

When the FULL_DISK_INIT configuration parameter is set to 1, any instance startup command (for example, oninit as well as oninit -i) resets the configuration parameter to 0.

If you start to run the oninit -i command when the FULL_DISK_INIT configuration parameter is set to 0 and the database server finds a page zero, the oninit -i command does not run and the server reports an error in the online.log.

Page zero is the HCL OneDB system page that contains general information about the server instance. This page is created when the server instance is initialized.
