SAS® Integration Technologies: Administrator's Guide (LDAP Version)

Configuring COM/DCOM for Active Server Page Access
Note: You can also configure your Active Server Page (ASP) application to access SAS using the IOM Bridge for
COM. You might want to use IOM Bridge for COM if either of the following are true:
• SAS is running on z/OS or a UNIX machine
• you want to share a configured SAS server with Java applications.
If you are using the IOM Bridge for COM, the configuration in this section is not required. See Choosing a Server
Configuration for details.
COM/DCOM Configuration
To configure a Windows Active Server Page (ASP) client running in Microsoft Internet Information Services (IIS) for
access to a Windows server using DCOM, you must perform two different types of configuration:
1.
A basic configuration that is similar to a standard Windows client that accesses a Windows server using
DCOM.
To perform this basic configuration, follow the instructions in Enabling DCOM on the Server and the Client.
2. Additional configuration steps that will enable a Web client to access an IOM server. There are two ways that
you can access a Windows Server using COM/DCOM:
♦ To configure access to a local COM IOM server, see Accessing a Local COM IOM Server from an
Active Server Page.
♦ To configure access to a remote DCOM IOM server, see Accessing a Remote DCOM IOM Server
from an Active Server Page.
Permissions
Use dcomcnfg to configure the SAS.Workspace (SAS Version 9.1) application. To configure the DCOM or COM
when using ASP, you must change access and launch permissions for the SAS.Workspace (SAS Version 9.1)
application. Therefore, you should also familiarize yourself with Setting Permissions per Application on Windows
NT/2000 or Setting Permissions per Application on Windows XP.
If you are experienced with using IIS and DCOM and only need to know the permissions required for your setup, see
the following table for details about these permissions.

• IUSR_ • IUSR_
so it is launched as a different user;
• IWAM_ • IWAM_
however, this is not necessary. Refer to
