11 Application Scripts Description and Usage
This chapter describes how to customize sample scripts that let you start and stop the SAP Central
Instance (CI) and the SAP Database (DB) Instance. To use SAP application services in the Adaptive
Computing Controller (ACC), it is required to have a CI and a DB Instance installed. To be able to
start an SAP application service instance on a virtual hostname, it is necessary to use start and stop
scripts. These scripts are run from the SAP GUI, and SAP provides some of them. For starting and
stopping of application services with Windows, SAP documentation refers the user to
implementation partner information

. The purpose of this chapter is to provide such information for
HP SE SAP ACC Integration users.

• Overview, page 61
