Starting and stopping the BPU's To start and stop the Aanval background processing units ("BPU's"), a helper script is provided and its usage is recommended. This helper script ("idsBackground.pl") is located within the /apps/ directory relative to your Aanval installation. Help on usage for this helper script can be accessed by running idsBackground.pl with the -help parameter. Starting the BPU's To start the BPU's, run the following command from the /apps/ directory of your Aanval installation: perl idsBackground.pl -start or if you prefer and the script has execute permissions: ./idsBackground.pl -start Stopping the BPU's To stop the BPU's, run the following command from the /apps/ directory of your Aanval installation: perl idsBackground.pl -stop or if you prefer and the script has execute permissions: ./idsBackground.pl -stop Logos and trademarks are property of their respective owners. |
