2 Starting and Monitoring ACSLS

Once ACSLS has been installed and configured with the attached library, the application can be enabled with the command, acsss enable. The acsss macro manipulates the multiple services that are associated with ACSLS, bringing them up and shutting them down in the proper order, and providing a high-level view of the overall system status.

Depending on the installation, an ACSLS application is an aggregate consisting of up to seven services that are installed on the Solaris or Linux system:

• acsdb - maintains the ACSLS library database.

• acsls - library control software that executes library operations.

• weblogic - web server for the ACSLS GUI.

• surrogate - communication link between java services and acsls.

• rmi-registry - lookup service for named java objects and methods.

• smce - SCSI Media Changer Emulation of logical libraries.

• stmf - target mode framework for logical libraries.

The first two services are common to all installations. The weblogic, surrogate, and rmi-registry services are present where the ACSLS GUI has been installed. The smce and stmf service is seen on Solaris systems where logical library support has been configured. All of theses services are manipulated by the ACSLS user with the single macro, acsss.
