The PingDirectoryProxy server can prime the global indexes at startup from the backend directory server or from a peer proxy server, preferably one that resides on the same LAN or subnet.
When priming occurs locally, you can avoid WAN bandwidth consumption and reduce the
processing load on the directory servers in the topology. You can specify the data sources
for the index priming and the order in which priming occurs from these sources. Use the
prime-index-source property to specify the sources of data, either
file or some combination of the two.
The order you specify is the order in which priming is attempted from these sources. Priming is most efficient if the source server is on the same local network as the PingDirectoryProxy server.
For example, if you specify
prime-index-source:file,ds, priming is
performed from the
global-index data file created from the previous run of
the directory servers. If the entire global index has been primed previously from a startup
or reloaded-index directory server's source, the contents of the global index are written
to disk periodically with the
