**Hi,**  
**I was trying to install elasticsearch-6.3.0 on my Linux server (RHEL 6.8) using following command:**

> rpm -ivh /path/to/elasticsearch-oss-6.3.1.rpm

**Which threw this exception:**  
warning: /data/softwarePackages/GrayLog/elasticsearch-6.3.0.rpm: Header V4 RSA/SHA512 Signature, key ID d88e42b4: NOKEY  
Preparing... ########################################### [100%]

### NOT starting on installation, please execute the following statements to configure elasticsearch service to start automatically using chkconfig

sudo chkconfig --add elasticsearch

### You can start elasticsearch service by executing

sudo service elasticsearch start

**Java:**

OMR - 713f08e  
IBM - c041ee8)  
JCL - 20171113\_01 based on Oracle jdk8u151-b12

When I tried to install the same RPM Package on a different machine using OpenJDK, it worked properly.

Thanks for help in advance 🙂

As per the [support matrix](https://www.elastic.co/support/matrix#matrix_jvm) IBM Java is not supported.
