Question
Which TCP/IP ports are used by IBM Engineering Requirements Management DOORS?
Answer
When setting up DOORS two default port numbers are provided for the configuration:
- One for the database server port
- One for the license server port
When DOORS is used in a client/server setup, where the license and database server are hosted across a WAN with a firewall in place, then the firewall must have three open bidirectional ports to allow a connection to be established for sending and receiving license or database information.
- During the database server installation a default port number of 36677 is used and must not be changed unless you have reason to do so. DOORS client setup prompts the user to specify the database server port number being used and therefore the user should be aware of the port number in use to access data.
On the database server machine responses to client requests admitted over an established connection will be handled over a dynamically assigned port. - Server licenses provided to clients are created with a default port number of 19353 or 27000 for connection to the "FlexLM License Manager" (also known as "Flexnet"). DOORS client machines need to be configured to the port number being used.
- By default the port for the license vendor daemon is randomly assigned by the operating system.
To allow license requests through a firewall the daemon must have a port be specifically assigned.
This is done by adding the port number to the vendor daemon line in the "license.dat" file.
The VENDOR line would look like this:
VENDOR ibmratl PORT=<port number>
For example:
VENDOR ibmratl PORT=19354
Note: If there are firewalls on each end of the WAN connection, the same port must be opened on both ends.
DOORS clients can be setup to send email notifications when there is a failed attempt to log in to DOORS or for notification about users change proposals in DOORS, using the Change Proposal System. Therefore port 25 must be open in the firewall for each client attempting to use DOORS; and must not be used for other purposes.
