Figure 2. Could Not Accept Changes: The currently displayed page contains invalid values.
Resolution
Complete the following steps to configure the session server to use a fixed port number for JMX communication:
- Locate the container.properties file located in the %VHI_ROOT%/sesssrvr/conf directory. Note: You are modifying the session server configuration, not the management server configuration.
- In a text editor, on the rmi.export.port.ssl line, set a desired port number for encrypted RMI communications. (The default value 0 indicates use of arbitrary ephermeral ports.)
- Important: After saving the modified file, restart the management server as described in KB 7021352.
- Configure your firewall to allow communications on the port you specified in step 2.
Note: When you upgrade your product installation in the future (major release, service pack, or hotfix), the container.properties file may revert to new defaults. After upgrading, the above steps may need to be repeated.
