PingDataSync supports redundant failover servers that automatically become active when the primary server is not available. Multiple servers can be present in the topology in a configurable prioritized order.
Before installing a failover server, have a primary server already installed and configured. When installing the redundant server, the installer will copy the first server’s configuration.
The primary and secondary server configuration remain identical. Both servers should be
registered to the allservers
group and all dsconfig
changes need to be applied to the server group allservers
.
If the primary server has extensions defined, they should also be installed on any cloned or redundant servers. If extensions are missing from a secondary server, the following message is displayed during the installation:
Extension class <com.server.directory.sync.MissingSyncExtension> was not
found. Run manage-extension --install to install your extensions. Re-run setup to continue.
To remove a failover server, use the uninstall
command.
