This section is only relevant if an application communicates with TREX using HTTP.
The TREX setup program normally creates the Web site SAP_TREX_<instance_number> on the Web server. If an error occurred during this process, you have to create the Web site manually.
Open the Internet Information Services (Microsoft IIS 5.0) or the Internet Information Services (IIS) Manager (Microsoft IIS 6.0).
Windows 2000: Navigate to

Description |
SAP_TREX_<instance_number>, for example SAP_TREX_48 |
TCP Port |
<free_port> Recommendation
We recommend that you calculate the port as follows: 30000 + 100 * <instance_number> + 5 SAPinst calculates the ports of the TREX servers using this method. The method ensures that the ports do not clash with another TREX instance on the same host. Example
If the instance number is 48, the port is 34805. |
Path |
<disk_drive>:\usr\sap\trex_<instance_number> |
Permissions ( Read, Run scripts, and so on) |
None. Make sure that no field is checked. |
When you have created the Web site, you have to create a virtual directory. Use the secondary mouse button to click on the Web site SAP_TREX_<instance_number>, and choose
