Splunk DB Connect Cannot communicate with Task Error

[camper1]

I'm currently running Splunk 9.1.3 enterprise and Splunk DB Connect 3.16. When logging into Splunk I receive this error message in DB Connect that states, "Can not communicate with task server, check your settings."

I made sure it was in the correct path in dbx_settings.conf and customized.java.path as well.

Any suggestions would help.

I believe it was "https://jdk.java.net" 

Is there a certain package of OpenJDK or OracleJDK I should be using.

I tried that one. I have a debian test system, and downloaded the x64 Debian package from https://download.oracle.com/java/17/latest/jdk-17_linux-x64_bin.deb . Used dpkg to install, and it made a dir at /usr/lib/jvm/jdk-17-oracle-x64/ . However, providing this path to the DB-connect app still failed to reset the task server.

Then I tried using "apt install default-jre". It created the folder "/usr/lib/jvm/java-17-openjdk-amd64" along with links in the "/usr/lib/jvm/" directory. For some reason the splunk DB connect app would not accept "/usr/lib/jvm/java-17-openjdk-amd64" (failed to reset task server), but it did accept "/usr/lib/jvm/java-1.17.0-openjdk-amd64/" and successfully restarted the task server.

Unless you have a strong reason to use a specific JDK, I recommend trying different ones until you get one which works.

There is likely still something wrong with the Java installation. I remember installing JDK-17 myself and then it did not work but then I tried another package and it worked. Where are you getting your JDK from?
