There are two services for Adabas on Windows:
The Adabas Database Service is required to automatically start and stop databases at system start and shutdown.
The Adabas Shared Memory Service is required to create shared memory, since this requires additional privileges (not used on Windows operating systems before Windows Vista).
Notes:
If you start an Adabas nucleus session under Windows, the session will be terminated normally when you log off, however, in many cases, this behaviour is not desired.
In order to prevent this happening, you must start the database with the Adabas Database Service. The Adabas Database Service is also able to start databases automatically when Windows is booted. You can administrate the Adabas Database Service either via the DBA Workbench or via a command line interface.
Note:
Adabas Version 3.3 contains a different Adabas Database Service that
can be installed in parallel to the Version 6.1 Adabas Database Service. Please
use the Version 3.3 Adabas Database Service to process Version 3.3 databases
and the Version 6.1 Adabas Database Service to process Version 6.1
databases.
The DBA Workbench expects that the Adabas Database Service is always running - this is the case after the installation, provided that you don't stop the service. Whether a database can be started with the Adabas Database Service depends on the setting of in the menu of the Workbench.
Note:
If you have switched on Start As Service, the database can only be
started when the Adabas Database Service is running.
To install the Adabas Database Service
Enter ADASRV INSTALL at the Command
Prompt.
To start the Adabas Database Service
Enter ADASRV START at the Command
Prompt.
Or:
Choose Services (depending on the operating system, these may be
contained in either the Control Panel in the Main program group, or in
Administrative Tools in the Control Panel) and then choose the Adabas Database
Service from the Services list. Choose to start
the service.
To stop the Adabas Database Service
Enter ADASRV STOP at the Command
Prompt.
Or:
Choose Services (depending on the operating system, these may be
contained in either the Control Panel in the Main program group, or in
Administrative Tools in the Control Panel) and then choose the Adabas Database
Service from the Services list. Choose to stop the
service.
Note:
Stopping the Adabas Database Service also automatically stops any
Adabas databases that were started by the service.
To remove (uninstall) the Adabas Database Service
Enter ADASRV REMOVE at the Command
Prompt.
To set the startup mode of the Adabas Database Service
Choose Services (depending on the operating system, these may be contained in either the Control Panel in the Main program group, or in Administrative Tools in the Control Panel) and then choose the Adabas Database Service from the Services list.
Select the required startup type (automatic, manual or disabled) from the Startup type drop-down list box.
Choose OK to set the startup mode.
To set and show the startup mode of a database
If you want a database to be started automatically when the Adabas
Database Service starts, enter ADASRV Set <dbid>
AUTOSTART=Vnnn where nnn is the Adabas version, for
example for Version 6.1.1 you must specify AUTOSTART=V611.
If you want to display the value of AUTOSTART
for a single/each database, enter ADASRV SHOW
[<dbid>] at the Command Prompt.
Notes:
AUTOSTART parameter is
stored in the configuration file %ADADIR%\etc\ADABAS.INI
under the subtopic [DBID_<dbid>] in the section [DB_LIST].
To display the status of a database
If you want to display which databases are currently started by the
Adabas Database Service, enter ADASRV STATUS at the
Command Prompt.
To start and stop single databases
If the Adabas Database Service is already running, you can start a
single database by entering ADASRV START
<dbid> at the Command Prompt.
If you want to stop a single database that has been started by the
Adabas Database Service, enter ADASRV STOP
<dbid> at the Command Prompt.
Note:
You can use the Adabas Database Service to start and stop only
those databases for which the value of AUTOSTART has previously been
set.
On Windows Vista, a standard user should be able to start the Adabas nucleus or utilities, but a standard user is not allowed to create shared memories. For this reason, the Adabas Shared Memory Service has been introduced. The Adabas installation installs this service as an automatic service, and therefore the service should always have the status Started.
However, it is possible to stop, start, remove and install the service from the command line, for example when a fix for the service is provided:
To install the service, enter adashm install [auto] at
the command prompt. If you specify auto, the startup type is
automatic, otherwise it is manual.
To start the service, enter adashm start at the command
prompt.
To stop the service, enter adashm stop at the command
prompt.
To remove the service, enter adashm remove at the command
prompt.
Currently, the Adabas Shared Memory Service is only used under Windows Vista, but it is also installed on the other Windows platforms in order to have a unified installation for all Windows platforms.
