Hello,

We are seeing the below error after our linux upgrade, Could someone please help us fix this issue?

Unable to initialize modular input "server" defined in the app "splunk_app_db_connect": Introspecting scheme=server: script running failed (exited with code 127).

When i saw this issue last time, i have set the JAVA_HOME path in splunk-launch.conf file, it worked then but we are seeing this error again

Please help me out.

Thanks

Just figured out the issue, Posting it here where it may help anyone with same situation.

Whenever linux patching is getting done, it is also updating our Java version,

So I went ahead and set the JAVA_HOME path again.

Steps followed:

1.found the java installation path on our linux box using the below command.

$(dirname $(dirname $(readlink -f $(which javac))))

2.Executed the below command after getting the path.

JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.312.b07-1.el7_9.x86_64

3. Updated the JAVA_HOME path in splunk-launch.conf file

/opt/splunk/etc/splunk-launch.conf Modify the following line to suit the location of your Splunk install. # If unset, Splunk will use the parent of the directory containing the splunk # CLI executable. # # SPLUNK_HOME=/opt/splunk-home JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.312.b07-1.el7_9.x86_64

4. Updated the same JAVA_HOME path in the UI of Splunk DB connect-Configuration-Settings-JRE Installation path

5. Did a Splunk restart and it worked.

Happy Splunking
