At the most potential acceleration: WISKI Calculation-Server.
WISKI WCS
Water Resources Management
Key Features
Relocation of calculation routines from the client computer onto an optimized server system
Reduction of network load, as only the results are transferred to the client computers
Automatic recalculation of dependant values from new or corrected source data. This depends on the specific WISKI calculation configurations (aggregated main values, W/Q conversion through rating curves, etc.)
Automatic plausibility checks of new data
Database independency
Scalability: multiple calculation servers can be installed on multiple servers
No additional load on the DB-server
Based on the WISKI kernel system
WCS uses the technical, specialist calculation methods in WISKI
Detailed online log
Detailed protocol files
Freely configurable processing times. Option to configure calculation times to take place at night when the system load is at a minimum
Prioritisation of data calculation possible. Thus, high priority data can be calculated first
The WISKI calculation server (WCS) if of particular importance when running in conjunction with SODA (remote call server) and the WSP (WISKI Service Provider) as it offers the possibility to automatically process the data as it enters the system. An example would be the conversion from W to Q; the WCS can then also carry out the plausibility checking of this new data. Con-sequently, the new data is made available within a very short time for export and reporting.
The WCS connects with the WISKI database and continuously monitors the contents of the database. This monitoring, however, does not cause any noticable network load. If new data enters the database or existing data is changed, the WCS immediately starts the update proce-dure of all high resolution time series and dependant parameters. The calculation of aggre-gated main values will be initialised as soon as all the required source values are present. In this way all daily values, for example can be calculated after the end of the day. Following the update of the time series, the plausibility checking of this data is automatically initiated.
Additionally, the WCS can be configured to prioritise the update of certain data. For example, certain high-priority time series can be defined such as the flows from important river gauges. These time series will always be calculated before other time series assigned with a lower pri-ority.
The WCS can be configured to deal with specific situations, such as running at times of low system load to reduce the strain on the database. For example, it is possible to only update the database between the times of 17:00 and 22:00 and from 00:00 to 08:00. If current data is required outside these times then the calculation would be carried out – as in a system with-out the WCS – automatically when data is accessed by the client.
In addition to calculations, the WCS also carries out the plausibility checks configured in WISKI and writes the results into the database. This means the WISKI user can directly view the sec-tions of data highlighted by the plausibility check in the graph.
An online protocol is available for all calculation and plausibility processes undertaken. There-fore the possibility always exists to recognise which time series the WCS is currently process-ing. Furthermore, the WCS calculation and plausibility results can also be written to protocol files. This allows all past actions to be traced.
