Non-Lawson System Components

Your horizontally scaled system will contain the following components (and any prerequisites these components may have):

• Multiple machines, each set up with the identical version of the same operating system

• WebSphere Application Server on each machine, with WebSphere Application Server Network Deployment software on one machine

• A web server or, optionally, a load balancer linked to multiple web servers

• A relational database management system

• An LDAP server

• A shared file system (NFS is not supported)

All machines in the horizontally scaled system or cluster must point to the same instance of the RDBMS, LDAP, web server or load balancer, and the shared file system. For more information, see the Horizontal Scaling Installation Guide and the vendor documentation for each of the non-Lawson components.
