Configuration of Property Files for Windchill PDMLink and PTC FlexPLM Clusters
Add the following properties to custom.lcs.properties on each node of the cluster:
flexPLM.multiple.ServletEngines=true

com.lcs.wc.util.Logging.MultiThreadedLogs=true
Change the following property to be a single save location, which is relative to single node local Windchill/logs:
com.lcs.wc.util.LCSAccessLog.filename=\\logs\\LCSAccess.log
For example, if you are saving to a local SANSDISK share from multiple nodes:
com.lcs.wc.util.LCSAccessLog.filename=\SANSDISK\PLMlogs\LCSAccess.log
