The Streams Domain Manager cannot be opened.
A possible cause is that the installation owner is not authorized to use the X Window session. This problem can occur if the X Window session was started as user root when the user initially logged on to the system as root. Streams attempts to start the Domain Manager on behalf of the installation owner who is a non-root user.
For more information, see the messages in the following section of the installation log file: Show Domain Manager. You can open the Domain Manager from the command line by using the DomainManager.sh script in the product installation directory or streamtool launch --domainmgr command.
