Cache configuration

Since 2020.02 it is possible to use the localCacheSizeMB in the clientConfig.xml to tune the amount of in memory caching the PI service is allowed to do. This can be quite useful for performance tuning when using seamless integration with the archive.

This setting was already available to the Operator Client and Forecasting Shell Servers. If not configured a default cache size of 500MByte will be used.

Configure Database connection over Active Directory

When using MS Sql Server it is possible to connect to the database through Active Directory. This can be configured by updating the client configuration file (see example below). 

• remove user
• remove encryptedPassword
• extend URL by adding integratedSecurity=true
  

Furthermore it is necessary to copy sqljdbc_auth.dll from the Master Controller build/lib folder installation to the Tomcat/bin folder.

FewsPiService.properties

The FEWS Web Services have a custom property file that can be used to make service specific configurations available. This is a property file that is located in the FEWS configuration in the directory:

%REGION_HOME%/Config/PiClientConfigFiles/FewsPiService.properties

For more information about the possible properties, see FEWS Web Services configuration FewsPiService.properties. 

Global Properties

In case global properties are needed by the FEWS Web Services, a global.properties file can be put in the Region_Home directory as well. If the same global.properties is available in the RootConfigFile in the FEWS configuration, the properties will be overwritten by the one in the FEWS database

Index Files

Since 2018.02 the FEWS Web Services will not startup before an index file is available in the Database. Index files are created automatically by Forecasting Shells. This means that the FEWS Web Services will only start if a running Forecasting Shell is available on the live system.
