Model Repository Connectivity

Model Repository Connectivity

The Model Repository Service connects to the Model repository using JDBC drivers. Informatica Developer, Informatica Analyst, Informatica Administrator, and the Data Integration Service communicate with the Model Repository Service over TCP/IP. Informatica Developer, Informatica Analyst, and Data Integration Service are Model repository clients.
The following figure shows how a Model repository client connects to the Model repository database:
The figure contains sample Model repository clients, nodes A and B, and the Model repository database. The sample Model repository clients include Informatica Developer, Informatica Analyst, and Data Integration Service.
  1. A Model repository client sends a repository connection request to the master gateway node, which is the entry point to the domain.
  2. The Service Manager sends back the host name and port number of the node running the Model Repository Service. In the diagram, the Model Repository Service is running on node A.
  3. The repository client establishes a TCP/IP connection with the Model Repository Service process on node A.
  4. The Model Repository Service process communicates with the Model repository database over JDBC. The Model Repository Service process stores objects in or retrieves objects from the Model repository database based on requests from the Model repository client.
The Model repository tables have an open architecture. Although you can view the repository tables, never manually edit them through other utilities. Informatica is not responsible for corrupted data that is caused by customer alteration of the repository tables or data within those tables.
