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 Informix® 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 to0
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 Informix® system page that contains general information about the server instance. This page is created when the server instance is initialized.
