The Assure UI server requires three consecutive ports for operation. When the server is installed, the default ports begin at 8410, so ports 8410, 8411, and 8412 will be used. If these port numbers are in use, you can use the Change Assure UI Server (CHGVSISVR) command to change the port number associated with the Assure UI server on the local system.
The starting port number is part of the URL used to access the Assure UI server.
Do the following to change the port number to be used by the Assure UI server on the local system:
Verify that the port triplet you want to use is available using the procedure in Port not available.
The Assure UI server must be ended using the procedure in Ending the Assure UI server - IBM i.
To change the port triplet you want to use, type
VSI001LIB/CHGVSISVR
and press F4 (Prompt).At the Port prompt, specify the starting port number to be used by the Assure UI server on the local system. Possible TCP port values range from 2001 through 65530.
Press Enter.
