Setting Up a COM/DCOM Server: Introduction
SAS can be configured to enable client access through Component Object Model (COM) interfaces. A COM connection can be established either locally (on the same machine) or remotely (on a different machine). For remote connections, the Distributed Component Object Model (DCOM) interface is used.
Since COM launches the SAS object server, spawners are not used in the COM/DCOM server environment. However, you can (and should) use the Version 9 Object Manager (or Version 8 Workspace Manager) to obtain a DCOM server. The server definitions can be administered through LDAP or provided in a configuration file. Alternatively, you can imbed the server information in your application program.
DCOM must be enabled on both the client machine and on the machine where the IOM server runs. The server machine requires additional configuration for DCOM object access and launch permissions.
When to Use a COM/DCOM Server ConfigurationYou can configure an object server as a COM/DCOM server if:
If you use a Java client, you must use an IOM Bridge server configuration instead.
Note: If your server or client machines run Windows XP Service Pack 2 or later, or Windows Server 2003 Service Pack 1 or later, you must change settings to enable DCOM functionality. See Configuring DCOM on Windows XP Service Pack 2 and Windows Server 2003 Service Pack 1 for more information.
