Using the License Server Manager
The license server manager handles the initial contact with your PTC software that uses FlexNet licensing. It passes the connection to the appropriate vendor daemon. A license server manager serves the following purposes:
Starts and maintains vendor daemons for serving license rights from different software.
Transfers specific software requests to the correct vendor daemon.
There are two versions of the license server manager for license administration:
lmadmin—Uses a graphical user interface (GUI)
lmgrd—Uses a command-line interface
PTC currently ships with its products a license server manager based on lmadmin with the ptc_d vendor daemon at version 11.17.1.0. It is a replacement to the lmgrd−based license server manager shipped with the earlier releases of PTC products. If you are using an lmgrd−based license server manager with ptc_d vendor daemon of version 10.8.x, it is recommended that you migrate to lmadmin although it is not necessary.
