Starting and Stopping TREX on Windows 

Purpose

The following sections explain how to start and stop TREX on Windows:

On Windows, you can use the following methods to start and stop TREX:

·        SAP Management console

·        Executable files startsap.exe and stopsap.exe

SAP Management Console

You use the SAP Management console, a snap-in in the Microsoft Management Console (MMC), to start and stop SAP systems and TREX instances. The snap-in consists of a root node of the SAP system, below which the various SAP systems and their TREX instances appear as subnodes. The system displays detailed information about the processes, the current status, and open alerts for the instances.

A newly-installed MMC allows you only to start a locally-installed SAP instance on the host that you are logged on to. If the MMC is configured for central system administration, you can start and stop the entire SAP system from a single host.

For more information about the SAP Management console and the snap-in for the MMC, see the online application help and the SAP Library on SAP Help Portal help.sap.com ® SAP NetWeaver ® .Solution Lifecycle Management ® Solution Monitoring ® Monitoring in CCMS ® Microsoft Management Console

As part of the installation of the global file system, the SAP service for the corresponding TREX instance (SAP<sapsid>_TRX<instance_number>) is registered as a Windows service. The service is configured so that it starts automatically when the host is started up, and stops automatically when the host is shut down. You can start and stop the service manually if necessary. You can also start the TREX servers individually for test purposes or troubleshooting.

Prerequisites

During the installation of the global file system, a SAP Management console has been installed on your host machine.

Executable Files startsap.exe and stopsap.exe

You use the executable files startsap.exe and stopsap.exe to start and stop TREX. After installation of the TREX instance, these files are located in the directory <TREX_DIR>\exeand are executed from that directory.
