PeopleSoft MCF Cluster Architecture

In a PeopleSoft system, all application server processes, including MCF servers and REN servers, belong to an application server domain. Each domain can have only one REN server process (PSRENSRV), one queue server process (PSUQSRV), and one MCF log server process (PSMCFLOG). Domains can be redundantly clustered to provide failover. Logical queues can be serviced by multiple clusters for scalability. Support for scalability and failover is integrated into the configuration process.

The following diagram illustrates MCF cluster architecture.
