Procedure documentation Deleting the Registration of a Variant of the Current Database Instance Locate the document in its SAP Library structure

Use

You can register several variants of one Structure linkdatabase 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 Structure linkoperational state of the database instance. A database instance in ONLINE or ADMIN operational state remains active and is therefore recognized by the system.

Note

All parameters listed here apply only for the Microsoft Windows NT/Windows 2000 operating systems. The command is ignored under the UNIX operating system.

Prerequisites

The database instance is in the OFFLINE operational state.

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

You should only use the options -q | –quick and -s | –slow if errors occur and in consultation with Structure linkSAP DB Support.

Example

db_unreg myDB -f

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