Checklists

Purpose

The procedure depends on the following:

The type of data storage you use (centralized or decentralized)
The hardware you are using (individual hosts or blade system)

Below are the checklists for the different scenarios.

Individual hosts with central data storage

!	Action
	On the file server:
	Install a TREX global file system (see the TREX installation guide)
	Create a Central TREX Data Directory
	On all TREX hosts
	Install a TREX dialog instance (see the TREX installation guide)
	Only UNIX: Mount the Central TREX Data Directory
	Only Windows: Define a network drive for the central TREX data directory
	Start TREX
	On a future master name server
	Configure the Landscape
	With an RFC connection: On all TREX hosts and in the SAP system
	Configure the RFC Connection
	With an HTTP connection: On the J2EE Engine
	Configure the HTTP Connection

Individual hosts with decentralized data storage

!	Action
	On the file server:
	Install TREX (see the TREX installation guide Single Host)
	Activate the Configuration Clones
	On all server blades on which TREX is to run
	Start TREX
	On a future master name server
	Configure the Landscape
	With an RFC connection: On all TREX hosts and in the SAP system
	Configure the RFC Connection
	With an HTTP connection: On the J2EE Engine
	Configure the HTTP Connection

Individual hosts with decentralized data storage

!	Action
	On a future master name server
	Install a central TREX instance (see the TREX installation guide)
	On all other TREX hosts
	Install a TREX dialog instance (see the TREX installation guide)
	On all TREX hosts
	Start TREX
	On a future master name server
	Configure the Landscape
	With an RFC connection: On all TREX hosts and in the SAP system
	Configure the RFC Connection
	With an HTTP connection: On the J2EE Engine
	Configure the HTTP Connection
