The Application Server has a few built-in programs that
instruct the server to perform special administrative tasks. Starting
with Release 8.2 of Application Dispatcher, you can use an administration
interface to perform these tasks. To access the interface, enter the
Application Broker URL in your Web browser. The Application Broker
URL depends on your Web server platform and the Application Broker
location. Typical URLs might be
http://yourserver/cgi-bin/broker (UNIX or z/OS)
http://yourserver/scripts/broker.exe (Windows)
When you access the
Application Broker URL using no parameters, a welcome page appears
in your Web browser. This page gives you access to an administration
interface,
SAS/IntrNet samples, and
SAS/IntrNet documentation. Click
on the Application Dispatcher Administration link to display information
about all defined Application Dispatcher services. Links are provided
to administrative and status programs for each service. The available
programs are described below. The administration interface can be
password protected using the BrokerPassword directive in the Application
Broker configuration file. To disable the administration interface,
use the DebugMask directive to disable _DEBUG=4.
Note: If there is a
customized Application Broker welcome
page, then it displays instead of
this default welcome page when you enter the Application Broker URL
in your Web browser. If this is the case, and if you want to view
the services that are available from the default welcome page, then
add _DEBUG=4 to the URL, as follows:
http://yourserver/cgi-bin/broker.exe?_debug=4
The following administrative
programs are available for Application Dispatcher services.

Stops the Application Server. All currently active requests
are allowed to complete. An optional _WAIT parameter can be used to
specify a maximum wait time (in seconds) for any sessions to expire.
An Application Server that has received a STOP command with a _WAIT
parameter accepts requests that access existing sessions, but do not
accept other new requests. The default value for _WAIT is zero. BREAK
and ENDSAS commands are also supported for compatibility with earlier
releases, although the STOP command is recommended.

Executes a simple program that verifies that the Application
Server is working correctly.
|
|
|
Displays a status page for the server that contains useful
information, such as when the server was started and how many jobs
it has processed.

In addition to using
the administration interface, you can execute an Application Server
administration program by supplying the name of the program in an
Application Dispatcher request. For example,
http://yourserver/cgi-bin/broker?_service=default&_program=ping
These special program
names are not case sensitive. If you start the Application Server
by using a password, you must supply the password to execute the STOP
program. For example,
http://yourserver/cgi-bin/broker?_service=default&_program=stop&_adminpw=foo
Note: If you do not start the Application
Server by using a password, any client can run the STOP program and
shut down your server.
