Forecasting Shell Server
The forecasting shell server is the server for execution of forecast runs. It contains the modelling software and it's operation is controlled by the Master Controller
- advised internal memory and CPU: Minimum 2 GB RAM and 1 one CPU core per FSS instance, CPU typically Intel Xeon 2.33 GHz or equivalent.
- operating system: Windows 2000/XP/2003, Linux RedHat/CentOS/SUSE contains modelling software (incl. licenses), OS usually dependent on 3rd party modules and modelling software
- amount needed: Minimum 2, more depends on computational load
Master Controller Server
The master controller organises task traffic and scheduling
- advised internal memory and CPU: 1 GB RAM per MC instance. CPU typically Intel Xeon 2.33 GHz or equivalent.
- operating system: Linux RedHat/CentOS/SUSE, Windows 2000/2003. Other Unix-like operating systems possible (e.g. HP-UX, Solaris), as long as there is a Sun JDK 1.7 available for the OS. JBoss 4.0.2 may be on a separate server
- amount needed: 1 or 2
Central Database
This is the central data repository, linked to the master controller. We support Oracle 10g (back to Oracle 9 supported), PostgreSQL 8.2 / 9.2 / 9.3, MS SQLServer 2000/2005, MS SQLServer 2008. This list is not exhaustive, so contact us if you are thinking of using a different database or a different type.
- advised internal memory and CPU: See Database vendor requirements. Typically 1 GB RAM per DB instance and CPU Intel Xeon 2.33 GHz or equivalent.
- The database instance(s) can be a hosted on an existing database server or cluster.
- uses 1 instance for each Master controller
Operator clients
The operator client (Gui) is the user end - thick client, multiplied by copying. The operator client uses a local datastore, MsAccess, Derby or the open source Firebird db.
- advised internal memory and CPU: none, normal pc
- operating system: Windows 2000/XP/2003/Windows 7/Windows 8, Linux RedHat/CentOS/SUSE
- amount needed: as many as there are clients
- possibilities to use under CITRIX available
- using a mouse with scroll wheel is recommended
