Sun Microsystems 3 manual Restoring Database Tables

Managing an Engine Database

As in all iPlanet UDS command line specifications, if you use a name that includes a space, you should enclose the name in double quotation marks.

The following table describes the command line flags for the DrDump command:

Flag	Description
-eengine_name	The name of the iIS engine in the current environment. This
	flag is required.
-ddirectory_name	The directory in which to place the data files. The default
	value is the root directory.
-vdata_file_name	The name of the data file. The default value is dumprest.log.
-t	The category of tables to dump. Valid values are
registrationstate	REGISTRATION, STATE, HISTORY. The default is all
history	categories. To specify a combination of two categories, use a
	colon (:) between categories. For example:
	-t registration:state
	Alternatively, you can enter the -tflag for each category. For
	example:
	-e myEngine -t registration -t state

If you have set the environment variables described in “Dump/Restore Environment Variables” on page 136, then you do not need to supply values for the command line flags.

Restoring Database Tables

The following sections describe how to retrieve data which has been written to an ASCII file and restore it to an engine database. To restore data to an engine database, the engine must have been cold started. Cold starting an engine creates empty database tables that correspond to the engine database schema.

You can use either the Dump/Restore application or its command-line equivalent.

NOTE If you are upgrading to a new release and have customized your process engine database schema, be sure to read the following section, “Preserving Engine Database Schema Customizations.”
