Installing PTC FlexPLM on an Existing Windchill PDMLink Multi-Node Cluster
Install PTC FlexPLM according to documentation on one node in the cluster with all others shut down. Verify that Windchill PDMLink is fully accessible and configured before installing PTC FlexPLM.
To install PTC FlexPLM on all other nodes in the cluster, execute the PTC FlexPLM installer Windchill/src/com/lcs/build/installer/install.(sh)(bat) by passing the following additional parameter:
-Dinstaller.NoDB=true
For example:
install.sh -Dinstaller.NoDB=true
This ensures that PTC FlexPLM is configured on the other cluster nodes and does not attempt to execute any database-level calls such as schema setup, loadfiles, or DB configuration utilities.
