Errors and Recovery for the Server Parameter File

If an error occurs while reading the server parameter file (during startup or an export
operation), or while writing the server parameter file during its creation, the operation
terminates with an error reported to the user.
If an error occurs while reading or writing the server parameter file during a
parameter update, the error is reported in the alert log and all subsequent parameter
updates to the server parameter file are ignored. At this point, you can take one of the
following actions:
■ Shut down the instance, recover the server parameter file, and then restart the
instance.
■ Continue to run the database if you do not care that subsequent parameter
updates will not be persistent.[@more@]
