The Jiwa Plugin Scheduler service by default can only be configured to connect and execute plugin code in a single database.
These instructions detail how to have multiple instances of the service running on the same machine, such that each instance can be configured to connect to different databases.
Copy the Jiwa folder
Locate the Jiwa 7 folder and copy it, naming it as desired.
Run sc.exe
Open a command prompt and type in the following:
sc.exe create "Jiwa Service 2" binPath= "C:\Program Files (x86)\Jiwa Financials\Service2\JiwaPluginSchedulerService.exe"
Note that the "Jiwa Service 2" is the name of the service, and the binPath is the location of the executable.
Edit the configuration file
Locate the JiwaPluginSchedulerService.exe.config in the folder copied in the first step (C:\Program Files (x86)\Jiwa Financials\Service2) and edit the contents to connect to the desired database.
Configure the service
Open service.msc and locate your new service and right-click, choose "Properties" from the context menu and ensure the Start up type and Log On information as as desired.
Start the service
Open service.msc and start the service in the usual fashion.
