High availability for free-text search with Apache zookeeper

In version 7.0, PolicyCenter supported high availability using a built-in clustering system.

In version 8.0, that system was replaced with a system that uses the Apache Zookeeper project. PolicyCenter does not include the software for Apache Zookeeper, but it is provided for free at the location:

https://zookeeper.apache.org/

For Zookeeper configuration, consult the Zookeeper documentation.

To configure PolicyCenter free-text search for use with Zookeeper requires modifications to the following files:

  • solrserver-config.xml – Configures PolicyCenter to connect with SolrCloud servers in a ZooKeeper ensemble
  • zoo.cfg – Configures each SolrCloud server for membership in a ZooKeeper ensemble
  • myID – Configures each SolrCloud server with its ordinal number in the ensemble
