Add the following settings to the end of the prconfig.xml file:

• Optimize XML output – Set to true by default to facilitate extracting a large number of class instances to XML: <env name= “compatibility/BIXUseOptimizedClipboardXML” value= “true” />

• Disable forward chaining – Enable or disable forward chaining calculations of properties when loading the clipboard for BIX extract: <env name= “compatibility/BIXdisableForwardChaining” value= “true”>

  The default setting is TRUE.

• Disable backward chaining – Enable or disable backward chaining calculations of properties when loading the clipboard for BIX extracts: <env name=”compatibility/BIXdisableBackwardChaining” value = “true” />

  The default setting is TRUE.

• Disable declarative processing – Enable or disable declarative processing: <env name=”declarative/enabled” value = “false” />

  Note: Only use this setting when you are running BIX from the command line. If you use this setting on a node to improve performance, you cannot open or create rules on that node.

• Include class instances added during a batch run – Enable or disable whether class instances added to the Pega Platform database after a batch run begins execution are included in the extract: <env name=”bix/useHistoryClasses” value=”true” />

  Note: bix/useHistoryClasses only works when using the Use Last Updated Time as Start filter option. If command-line parameters such as –u, -U, -d, and -D are passed while running the BIX script, bix/useHistoryClasses will not have any effect even if it is set to true. For details on command-line parameters, see BIX parameters and command-line arguments.
