Making Web Server Settings (SAP Library - ITS Tuning and Troubleshooting Guide)

Making Web Server Settings

Use

You use this procedure to make Web server settings.

Web server settings depend on the type of Web server you are using to install the Internet Transaction Server (ITS).

Procedure

Here are some recommended Web server settings for:

Microsoft Internet Information Server (IIS)
Netscape Enterprise Server (NES)

Microsoft Internet Information Server (IIS)

If you are using the IIS, you can configure the Information Server API (ISAPI) extension of WGate by making the following settings in the Microsoft Management Console:

Define WGate as an ISAPI filter.

The location of the Web server extension file wgate.dll has changed:

Prior to Release 4.6D, there was a separate wgate.dll file for each Web server instance (that is, for each IIS virtual site) and ITS instance.

Starting from Release 4.6D, there is just one wgate.dll file installed on a server-wide basis for all ITS instances.

In Web Site Properties, make sure that Run in separate memory space (isolated process) is unchecked.

From Release 4.6D, Web server instances no longer have to run in their own memory space:

In all releases up to and including Release 4.6C, you had to attach each ITS instance to a separate Web server instance.

This is because each Web server instance had to run in its own memory space to enable WGate to communicate with the correct AGate.

From Release 4.6D, you can attach several ITS instances to a single Web server instance.

In the new WGate configuration, WGate knows which AGate it should talk to in multiple instance configurations, so there is no need to run each Web server instance in its own memory space. This improves performance considerably.

In the SCRIPTS folder, make sure that Run in separate memory space (isolated process) is unchecked.

Note

For further information about the new WGate configuration, see the SAP@Web Installation Guide or the ITS Administration Guide.

Netscape Enterprise Server (NES)

If you are using the NES, you can configure the Network Server API (NSAPI) extension of WGate by making the following settings in the Netscape administration tool:

Set the value Maximum Simultaneous Requests equal to or higher than the maximum number of active users.

Result

Taking any of these steps should help to improve ITS performance.
