hi,everybody
now ,I install the app "splunk connect db v2" on splunk ,but when create connections the error occured "
Validating connection with URL [jdbc:oracle:thin:@BWPRDDB:1521:XE] failed, please verify that the connection is configured correctly."
in log dbx2.log ,I find the following error
"root@BWPRDCI:/opt/splunk_install/splunk/var/log/splunk>more more dbx2.log
more: A file or directory in the path name does not exist.

I have set java_home=/usr/java8_64/jre ,but the error still occured

to get mine working I had to use the directory /usr/java/jre1.8.0_74/. once I added this in the setup everything started to work.

that looks like you haven't configured the java environment properly. Is the RPC Service running (this is the red or green light in the center of the navigation bar)?

Post your inputs.conf from the DBX2 app.

Thanks
