How to Specify Repository Ports
Go Up to Administrator Guide
To change the ports that the server listens to you will need to add the following registry keys on the machine that the Repository Application Server is running on.
On the client side, in ER/Studio Data Architect you can use the menu Repository > Repository Properties. Change to the Server tab page and specify the ports that the client communicates to. The register value RepoServer Port mentioned before corresponds to the Communication Port listed on the Server tab. The register value RepoProbe Port corresponds to the Identification Port listed on the Server tab.
The identification port uses a UDP broadcast to identify running Repository servers that can be connected to in order to provide a list to the user (for example, the list in the Repository > Options dialog). This is optional and should not cause any issues if it is unavailable.
The communication port provides all communication between the ER/Studio client and the Repository server services, such as login requests, get diagram requests, checkout/check-in requests, event updates, and any other operations requiring information from the Repository. All communication is initiated by the client via TCP/IP. This port is required for use of the Repository, although it can be changed to a different port number if necessary.
Note: The SSL port works like the Communications port, except all traffic is encrypted via SSL. The Repository listens on both the SSL port and the Communication port for connections. If a user chooses to use SSL in ER/Studio, then the connection will be made to the SSL port on the server rather than the Communication port for all repository operations. To enable SSL and configure the port you can use menu Repository > Repository Properties.
The registry key that stores this port number can be found on the client machine is RepoSSL Port and is under: HKEY_CURRENT_USER\Software\IDERA\ERStudio Data Architect 16.0\Repository
Where x.x is the version of ER/Studio Data Architect.
Enable SSL v3.0
On the client side (ER/Studio), you can enable SSL v3.0 in the Repository Properties dialog (under Server tab.)
Note: If you intend to enable SSL v3.0, then you should follow these steps: 1. Enable it in the registry on the server side and restart the services. 2. Run ER/Studio on the client side, go and enable the SSL v3.0 option in the Repository Properties dialog. 3. Log in.
