LANSA Composer

Subsystems and Jobs

The LANSA system in which LANSA Composer runs is a complete application execution environment supporting client/server as well as web applications. As such, it has a number of components that must be active on the server to provide the necessary application support.

When the installation is completed into a new LANSA system, the necessary subsystems and jobs are started for you. If you stop these subsystems or restart your system, you will need to restart the subsystems that provide LANSA application support for LANSA Composer.

Starting the listener

The LANSA listener provides communications services necessary to support both the client/server and web parts of LANSA Composer. The LANSA listener must be active in order to start the LANSA Composer windows client or to open the LANSA Composer operations console in a web browser.

The LANSA listener is started by starting the subsystem in which the listener jobs run. By default this subsystem has the same name as the program library used for the LANSA installation. So if you installed LANSA Composer into a new LANSA system using the suggested defaults, you would start the listener with this command:

STRSBS SBSD(LICPGMLIB/LICPGMLIB)

 

Starting the HTTP server

The HTTP server instance associated with the LANSA installation must be started in order to open the LANSA Composer operations console in a web browser.

The HTTP server instance is started by using the STRTCPSVR (Start TCP/IP server) command. By default, the HTTP server instance has the same name as the program library used for the LANSA installation. So if you installed LANSA Composer into a new LANSA system using the suggested defaults, you would start the listener with this command:

STRTCPSVR SERVER(*HTTP) HTTPSVR(LICPGMLIB)

 

Starting the Java Service Manager (JSM)

The Java Service Manager associated with the LANSA installation must be started in order to use LANSA Integrator services with LANSA Composer. This is necessary for many of the activities shipped with LANSA Composer.

The Java Service Manager is started by starting the subsystem into which it was installed. If you installed LANSA Composer into a new LANSA system using the suggested defaults, you would start the Java Service Manager with this command:

STRSBS SBSD(LICJSMLIB/LICJSMLIB)
