Troubleshooting Arbortext Publishing Engine Licensing
The Arbortext PE Request Manager itself does not need a license to run, but Arbortext Publishing Engine Interactive and the Arbortext PE sub-processes do require a license. A license error will report that the PTC_D_LICENSE_FILE Environment Variable is either missing or set to an incorrect value.
You can check the license information as long as the servlet container you are using has been configured for Arbortext Publishing Engine. Refer to Server Configuration for servlet configuration information.
The Arbortext Publishing Engine administrative web page has a License link that returns the License Information report. The report lists basic information about the installation, as well as the license source, the user under which Arbortext Publishing Engine is running, and the number of processor cores and packages on the Arbortext PE server. It also lists the optional software components installed and whether they are licensed.
A license error report will be returned with the information that PTC_D_LICENSE_FILE is either missing or set to an incorrect value (and the incorrect value will be provided).
The Arbortext Publishing Engine administrative web page has a Status link that includes the system Environment Variables in the report.
If PTC_D_LICENSE_FILE is set, it will be included in the Environment Variables report.
