Deleting the Registration of a Variant of the Current Database Instance 

Use

You can register several variants of one database instance (Registering a Variant of the Current Database Instance). The difference between these variants is that they use different variants of the database kernel.

With this command, you remove the specified variant of the current database instance from the server. Once you have done this, you will not be able to start this variant of the database instance again. The deletion procedure has no effect on the current operation status of the database instance. A database instance in WARM or COLD mode remains active and is thus recognized by the system.

All parameters listed here apply to the Windows NT operating system only. This command is ignored under the UNIX operating system.

Prerequisites

The database instance is in OFFLINE mode.

You have the DBM operator authorization InstallMgm.

Syntax

db_unreg <option>

Options

You use the following options (<option>) to specify which database instance entry variant is to be deleted:

-f | -fast

-q | -quick

-s | -slow

The -q | -quick and -s | -slow options should only be used in case of error and in consultation with Support.

db_unreg MK1 -f

The registration of the fast variant of database instance MK1 is deleted.
