Splunk DB Connect: How to resolve error "JRE Status: OSError: [Errno 2] No such file or directory"?

svercelli — Tue, 16 Aug 2016 04:42:15 GMT

I've just installed Splunk on a new Linux Redhat instance, I'm not particularly familiar with Linux, but I believe everything to be working fine. The one thing that has become problematic is with Splunk DB Connect.

While setting it up, I've put in the path for Java I got with pwd just to make sure /usr/java/jdk1.8.0_102/

I've tried putting this as /usr/java/jdk1.8.0_102/jre as well, but I keep getting an error saying

JRE Status: OSError: [Errno 2] No such file or directory

Anyone know where I should start looking for the problem?

Did you set up environment variable named JAVA_HOME ? If not try setting it to /usr/java/jdk1.8.0_102/

It is, echo $JAVA_HOME reads /usr/java/jdk1.8.0_102

Did you complete the setup of the DB Connect app? There also we need to define JAVA_HOME as shown in the docs

This is what I'm doing. This error I'm getting is when i'm trying to input the JRE Installation path in the setup.

In that case did you verify access rights for the JDK folder?

I did not. Ive been operating under the assumption that since splunk was installed as root, I wouldn't need to modify the rights. Like I said, I'm fairly new to Linux. Mind walking me through?

Assuming Splunk would have the same privileges as root in this case then yes all permissions are there.

I will try.

First check the owner of your splunk folder using following command:

ls -lh

Use same command to verify the ownership for JDK folder, if both are same then you don't have a problem else either update the ownership of JDK folder or grant 777 access to the JDK home using following command, if this machine is just for testing purpose.

chmod +R 777 /usr/java/jdk1.8.0_102

The users were different, so i used chown to change the java ownership to the splunk user. checked and it shows that the ownership is now with splunk. It hasn't fixed the issue though, still getting the same error.

Hope we are referring to correct jdk ..

Can you run following command and see if it points to same value as the value JAVA_HOME in DB connect app

which java

Re: Splunk DB Connect: How to resolve error "JRE Status: OSError: [Errno 2] No such file or directory"?

svercelli — Tue, 16 Aug 2016 09:52:08 GMT

which java

/usr/bin/java

whereis java

java: /usr/bin/java /etc/java /usr/lib/java /usr/share/java /usr/share/man/man1/java.1

[root@DC2VTS01 java]# alternatives --config java

There are 2 programs which provide 'java'.

  Selection    Command
-----------------------------------------------
   1           /usr/java/jre1.8.0_101/bin/java
*+ 2           /usr/java/jdk1.8.0_102/jre/bin/java

Hi svercelli - Did you ever figure this out? I am having a similar issue.
