please can any one resolve my issue please. even am unable to understand the links on this issue.

Thanks in advance,

JAVA_HOME : C:/Program Files/Java/jdk1.8.0_45/jre

Ensure you have set the correct JAVA_HOME environment variable. also install the driver, as mentioned the docs. restart the splunkd

Thanks @splunker12er .
I have uninstalled the app and java and again installed java 1.8 and splunk successively and gave path. then got it 🙂

The stack trace is saying that Splunk has insufficient permissions to create the folder C:\Program Files\Splunk\var\lib\splunk\persistentstorage\dbx\global. Check the user with which you've installed Splunk has permissions to create files in the folder C:\Program Files\Splunk\var\lib\splunk\persistentstorage and it's subfolders.

I've just gone through a similar situation. Splunk doesn't seem to set up permissions in a WIndows environment as well as it does in a Linux environment.
