Background documentationparam_directdel Locate this document in the navigation structure

 

With this command you can delete the specified parameter from the database parameter file.

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

The system does check that the changes made are in accordance with the rules, and it overwrites invalid values when the database is 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

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

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

End of the caution.
