TIBCO EMS
The TIBCO EMS queues are secured via:
• A server administrator user account
• Client user accounts for both Windchill PDMLink and the ESI BusinessWorks application.
• Required authentication to access the queues
The user account credentials are not obfuscated. Refer to the Windchill Enterprise Systems Integration Installation and Configuration Guide - SAP for details on setting up EMS security measures. As the Windchill ESI administrator, you should be familiar with these measures and may wish to configure alerts or notifications in case there is a security breach.
