Ad Hoc Replication
Ad hoc replication means the copying of content from a master site to a Windchill File Server when the content is not available on a remote site and the user has set preferences to a Windchill File Server.
If a user attempts to download data that does not exist on the local File Server, the content is retrieved from the nearest proximity site that has the data and is also replicated to the local File Server. The next time another local user downloads the same document, it is retrieved directly from the local File Server.
When ad hoc replication occurs, predictive replication rules and schedules are created.
You can control ad hoc replication by setting the wt.fv.master.adhocCaching.flag property in the wt.properties file. This property can have the following values:
• 0—Ad hoc replication is disabled.
• 1—Ad hoc replication is enabled only if a rule exists for the content on a user’s preferred File Server.
• 2—Ad hoc replication is enabled for all conditions. This is the default value.
The wt.fv.master.adhocCaching.ThreadPoolSize property sets the number of concurrent threads that are available for ad hoc replication. The default value for this property is 3.

Ad hoc replication also works at a master site if it has replica vaults configured.
