- RDS 2.1 and above
- R-1 3.1 and above
- Using R-1, an R-1 Center equals to RDS Controller; an R-1 Edge equals to RDS Satellite.
What are the different "Components" and which ones do I need installed? Can I have more than one component installed on a given machine?
R-1 is composed of three components: Center / Edge / Console. Each of the components is part of the installation kit. In RDS, these components are referred to: Controller / Satellite / Console, respectively.
During the installation you can specify which components you wish to install. If all you need is to replicate a source server to a target server, you can install just the Edge component on the target server.
For evaluation purpose, it is recommended to do a complete installation on both servers and figure out later what exactly is needed on each server.
Each component is independent of the others. You can install any component on any machine, depending on your replication process' needs:
Center - The Center is the initiator of any R-1 distribution job and must therefore be installed on any system that will initiate a distribution. Once a job is submitted to the Center through the R-1 Console (through the Console GUI or the Console CLI), the background services on the Center take over. Whether the job is set to run immediately or on a predefined schedule, the Center will ensure that the jobs are initiated without any further user interaction.
Edge - The Edge component must be installed on any system that responds to distribution and replication requests initiated by a Center. It is a passive element that runs as a background process, and is awakened by a distribution request originating from a Center. It then allows R-1 to perform the distribution, again, regardless of whether a user is actively logged on or not.
Console - The Console is the main means for an end-user to interact with R-1. Whether using the R-1 Console command-line interface (CLI), the R-1 Console graphical user interface (GUI), or the R-1 Web UI, the Console is a “window” to the Center.
The Console connects the user to any system with the Center component installed and allows the user to perform all forms of administrative tasks with respect to replication jobs defined on the Center. This provides an ease-of-management layer in the enterprise environment.
The Console does not need to be installed on the system with the Center component installed. It can be installed on any system that can form a TCP/IP session with the Center (i.e. via LAN, WAN, VPN or a dial-up connection). This means that there can be multiple Consoles simultaneously administering R-1 jobs on a given Center.
