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

Setting up an IOM Bridge Server and Spawner
An IOM Bridge server configuration enables client access using the IOM Bridge for COM or IOM Bridge for Java.
The IOM Bridge for COM is a software component of Integration Technologies that is used (transparently) to enable
native COM/DCOM applications to access server data on either Windows platforms or on non−Windows platforms
such as a UNIX or z/OS. The IOM Bridge for Java is used (transparently) when a Java client accesses an IOM Server.
This bridge allows developers to write Java applications that access server data.
For more information about the IOM Bridge for COM and the IOM Bridge for Java, refer to Connecting Clients to
IOM Servers in the SAS Integration Technologies Technical Overview.
When to Use an IOM Bridge Server Configuration
You must use an IOM Bridge server configuration if:
• The object server will run on a non−Windows machine (for example, a UNIX−based machine); or if
• The object server will be accessed by Java client applications
You can also use an IOM Bridge server configuration if the object server will run on a Windows machine and will be
accessed by Windows clients. In this situation, clients will connect to the server using the IOM Bridge instead of
COM/DCOM.
Components of an IOM Bridge server configuration
An IOM Bridge Server configuration consists of:
• A server machine which hosts Version 9 of the SAS base software and the SAS Integration Technologies
software. The spawner program, which is part of Integration Technologies, must be running on the server
machine in order for clients to obtain access.
• A client application, which can run on the same machine as the server or on a remote machine. To connect to
the object server via TCP/IP, client applications must use the IOM Bridge for COM or IOM Bridge for Java
utilities provided with Integration Technologies. To request specific services from the object server, client
applications use Application Program Interfaces (APIs), also known as distributed objects, that are provided
with Integration Technologies.
• An LDAP server, which is a central repository that client and server software can access to obtain metadata
(or configuration information) about the object server. For IOM Bridge server configurations, the metadata
includes definitions for server objects and spawner objects. Optionally, the metadata can also include
definitions for login objects and logical name objects (which define groupings of servers, spawners, and other
associated objects.)
Note: If your configuration is very simple (that is, consisting of only one or two servers and clients) and does
not require strict security, you can use configuration files instead of an LDAP server to store the metadata for
servers and spawners.
Note: You can also supply the server parameters for the configuration directly in the application program.
