Primavera 18.8 Configuration with Weblogic Server

Hi

I am woriking on windows 2016 server (Windows instance on oracle cloud), trying to install EPPM 18.8. To create this environment I need to JAVA SDK, Oracle Weblogic Server, SQL Server 2017 (database server) along with EPPM 18.8 modules. 

I am using weblogic server 12.2.1.3.0 which is causing a problem with Node Manager, whenever I start P6 services from the weblogic server admin portion, it shows errror 

"For server P6, the Node Manager associated with machine localhost is not reachable."

I have investigated this error on internet, another cause of this error is

"weblogic.nodemanager.common.ConfigException: Identity key store file not found:

_{C:\Oracle\Middleware\Oracle_Home\user_projects\domains\base_domain\nodemanager\security\DemoIdentity.jks"}

As per Oracle this is a bug, any idea how to resolve this error.

regards

Mansoor
