Background documentationparam_directdel Locate this document in the navigation structure

 

You delete the specified parameter from the database parameter file.

This change only becomes effective the next time the database instance is restarted.

Be very careful when using this DBM command as it accesses the database instance parameter file directly.

The system does check that the changes made are in accordance with the rules, and it overwrites invalid values when the database instance is next restarted with the values from the default parameter file. However, this does not happen for the parameters RunDirectoryPath and KernelVersion, or for any volume parameters.

Caution Caution

If you delete these parameters, this can lead to severe inconsistencies during database operation.

End of the caution.

Prerequisites
