[resolved] Talend MDM 621 workflow console not returning in distributed install

[Anonymous]

Environment
RHEL 7.1
Tomcat 8.0
Talend MDM 6.2.1
Distribution
/opt/apache-tomcat-8.0 (external tomcat instance)
/opt/bonita
/opt/talendmdm
I have used the Talend-Installer-20160704_1411-V6.2.1-linux64-installer.run installer to install a custom installation of MDM to Linux
*Note: I left the default database as H2  
In the installation I selected to
Install to an external tomcat instance - Port 8080
Installed MDM to /opt/talendmdm
Installed Bonita to /opt/bonita - Port 8280
I've done as much configuration as I thought was required and tomcat starts and I can logon to Talend MDM.  Everything runs except the Workflow Console.
When I click on Workflow Console I see the following error
12-Jan-2017 12:50:50.975 INFO org.apache.catalina.core.StandardWrapperValve.invoke 12:50:50,967 ERROR

Has anyone else completed such an installation and if so what would be the first point of failure to check?
Cheers

Hi all,
I thought that I should get back to you all and let you know that I have now resolved this issue.  I ran a windows installation the same way I needed to on Linux and then made changes to the RHEL configuration to match.
I now have MDM and workflow running on RHEL 7 using a postgres 9.5 db.
Case closed.
Cheers
