COACH 14 Requirements

COACH has been successfully installed in various configurations within an enterprise environment. The most common scenario utilizes a dedicated database environment with a dedicated server for the COACH application. COACH will run on VM, however, it is strongly recommended that this environment be closely monitored to ensure that sharing of host resources does not impact performance. The following document provides recommendations for server hardware and software requirements for COACH installation.

Several factors will be involved in the actual size of your specific COACH installation:

- Number of concurrent users (impact: application server traffic and database concurrent connections)

- Volume of requests (impact: database connections, size of database)

- Size and complexity of individual transactions (impact: database size)

- Size of attachments attached to requests (impact: application server disk space)

The primary factors in sizing, however, will be the number of concurrent users/transactions and the size of the process (i.e. number of tasks/complexity). The larger the process, and the larger the number of requests for that process translates into more processing required on the application server as well as the database server.

Base System Requirements

Regardless of hardware sizing concerns, all installations of COACH have the following base requirements

Application Server Operating System

- Windows Server 2019 or higher (any edition)
