We installed CA Output Management Web Viewer 12.1 Not able to start Web Viewer.
Release:
Component: WBVLUW
Tomcat was not running. Reference the install Guide. Tomcat should be installed as a service (autostart) on the Windows Server, and then configured.
On a Windows Server especially, you want to be be running Tomcat as a service, and one that starts automatically. You can test Tomcat viability by running the startup.bat script and it will bring Tomcat up, but it will come right down again as the user who ran the script logs off the server.
. . So once Tomcat is running as a service and you've completed the configuration, there's one more thing you need to be sure you do. This is very important. Whatever UserID you specify as the administrator during the install and configuration... it must be that same user that signs into the Web Viewer for the first time to set up the users and repositories. It's also a very good idea to initially define a couple of other users as sysadmins in that initial session. This way should anything happen to the primary sysadmin, you'll have backups you can go to in order to continue maintaining the Web Viewer.
. . At that point, when you've gotten the base install running and configured, you should update to a newer Build so you have all of the available maintenance applied from the start of your usage. As all 12.1 Web Viewer Builds are cumulative, it's recommended you update using the latest Build available.
