Metadata interchange servers

Metadata interchange servers are computers that are used by InfoSphere® Metadata Asset Manager to run imports with bridges and connectors. When you import metadata, you choose a metadata interchange server where bridges or connectors are installed, and you select a bridge or connector.

During the installation of InfoSphere Information Server, client tier computers where bridges are installed and engine tier computers where connectors are installed are usually automatically designated as metadata interchange servers. However, when you are installing only the client tier you have the option to manually designate the metadata interchange server after installation.

The Common Metadata Administrator can manually designate metadata interchange servers on the Administration tab of InfoSphere Metadata Asset Manager or by using the command line. The Common Metadata Administrator uses the Administration tab to enable metadata interchange servers that are manually designated, and to disable metadata interchange servers.

You can specify a single metadata interchange server for both bridges and connectors if the metadata interchange agent, bridges, and connectors are installed on the same computer. Specify the HTTPS port for this server.

To enable bridge imports for most bridges, specify a computer where the metadata interchange agent is installed and specify the HTTPS port for the computer. Use the port number that was specified when the metadata interchange agent was installed. The default HTTPS port is 19443.

To enable connector imports and imports with the HDFS bridge, specify a computer where connectors are installed on the engine tier with InfoSphere DataStage® and QualityStage®. Do not specify an HTTPS port if only connectors are installed on the metadata interchange server.

The IBM InfoSphere Streams bridge and the IBM InfoSphere Master Data Management bridge. which are installed on the services tier automatically, are available to use with any metadata interchange server.

When you enable a metadata interchange server, users with the Common Metadata Importer role can select it on the New Import Area screen on the Import tab when they start an import. They can then use a bridge or connector that is installed on that computer to run an import.

Note: If bridges and connectors are both are installed on a designated metadata interchange server, but the connectors do not appear on the New Import Area screen, ensure that the host name that you specified for the metadata interchange server is the same name that was registered with the metadata repository when InfoSphere DataStage was installed on the computer. In some cases the registered name might include the domain name. See this technote for more information: http://www.ibm.com/support/docview.wss?uid=swg22014921.

Metadata interchange servers are listed as in use if one or more import areas have been created by using that server. You cannot delete a metadata interchange server if it is listed as in use.

If you disable a metadata interchange server, users cannot reimport staged imports that were created by using that server.
