With Delft-FEWS systems getting larger and more data stored in the central database it is sometimes good to review the memory settings of your Operator Client and Forecasting Shell client components. Changing these settings to more realistic values can greatly improve the performance of your system. The default settings of the Delft-FEWS settings are tuned for medium size systems, these default settings can be changed in the root configuration files (this only applies to Delft-FEWS version 2018.02 and later). There are two files that are used for these settings:
- clientConfig.xml (for OC, FSS and SA)
- global.properties (for OC, FSS and SA)
Client config.xml (for Delft-FEWS version 2018.02 and later)
The clientConfig.xml file can be used for memory allocation (RAM) and disk space allocation for local cache files. The default memory setting is <jvmOption>-Xmx1024m</jvmOption>. Increased memory allocation settings need to be configured using <jvmOption></jvmOption> elements.
