 v21 == Install the Janitor Service == There are some tasks on the server which have to be executed periodically. Previously this logic was executed with the heartbeats that the slaves sent. Because this lead to performance problems there is now an own windows service with an installer. Simply copy the  !HeuristicLab.Services.Hive.!JanitorServiceSetup-3.3.msi file to your server and install it. There are some tasks on the server that have to be executed periodically. Previously this logic was executed with the heartbeats that the slaves sent. Because this lead to performance problems there is now an own windows service with an installer. The installer is created with the NSIS (Nullsoft Scriptable Install System). Download and install NSIS from http://nsis.sourceforge.net/. The installer scripts are located in the Installers directory in the source tree. Right-click on the file HiveJanitorServiceInstaller.nsi and select ''Compile NSIS Script''. If everything works, you get, in the same directory, a file called ''HeuristicLab Hive Slave Installer.exe''. You can now copy and install this file on your server. Please note that you have to compile the HeuristicLab Services solution before as the installer just takes the binaries and creates the installer out of them. You can open *.nsi files with a text editor to see what's actually happening. You can also find there, at the beginning of the file, that BUILDCONFIGURATION is set to Debug. If you want to package Release binaries change this in the nsi file and rebuild the Services solution using Release mode.
