Repository Setup

You need to set up the repositories before CA SDM users can work with attachments.

The distributed architecture lets a site configure their repositories according to their needs. The servlet for a repository does not have to reside on the same server as the attached files. Sites can have a central servlet to access all their distributed repositories or have a dedicated servlet for each of their repository servers.

Consider the following setups when configuring repositories:

• Repository server on a protected CA SDM server—Sites that designate a repository server on a protected CA SDM server (typically a secondary server behind a firewall) do not need to expose the servlet on that computer. Rather, they can specify a servlet running on the primary server or other unrestricted CA SDM server and still upload and download successfully to that server. Depending on the network between the two CA SDM servers, some performance impact on upload and download can occur.

  Note: A good way to set up a remote repository is to install a secondary server with the repository on the remote server, and set the upload path to a local path.

• Servlet on the same server as the repository server—Sites that want optimal performance for attachment upload and download, and if network performance is an issue and if very large files are being attached, should consider this setup. This approach requires exposing the Tomcat port (typically 8080) on the server and should be noted if the computer is behind a firewall.
