Clustering WebSphere Commerce search
By completing this task, you can set up WebSphere Commerce search in a clustered environment. The WebSphere Commerce search cluster allows you to manage multiple WebSphere Commerce search instances from one WebSphere Application Server console.
Before you begin
If you plan on
replicating WebSphere Commerce search, ensure that you consider the
following replication recommendations:
- Setup one master search index server to hold the master index, which is then replicated to all the search servers that take search traffic. That is, there typically exists a dedicated index-building machine, which is known as the master, to build the index. There can only be one master; it cannot exist on multiple nodes in clustered environments. The master replicates the index to other search engine machines, which are known as targets. The runtime search performance is not affected during the index-building.
- Set up the master search index server and subordinate search index server (separately) on the same operating system. This set up ensures easier file copy operations between servers.
- Every deployment manager that has a copy of Solr federated to it, must also have a WebSphere Commerce environment federated to it. Otherwise, fixes and maintenance must be manually applied to each node.

Deploying the WebSphere Commerce search server:
Clustering the
federated environment:
After you federate your WebSphere Commerce environment, you can configure clustering. Clustering provides failover protection and workload balancing.
