This blog entry is the third and last part of the series „Create APEX in AWS“. Here I describe the installation and configuration of Apache Tomcat and the deployment of the ORDS application in Tomcat. Later I will explain the installation of the Webserver Nginx and configure it to access APEX via Apache Tomcat and ORDS.
Information about the installation of the APEX application in AWS can be found
here. The installation and configuration of Oracle Data rest service is described here. Installation Apache Tomcat on the EC2 Container
As root: Download and extract the software:

This is the second part of my blog series about the installation and configuration an APEX database in the Amazon Cloud. Refer to following posts for the explanation of the whole solution:
Create the Virtual Private Cloud (Network) in AWS
At first, I will create my customer network in AWS.
In the AWS Console navigate to VPC and click on „Create VPC“. Specify the IPv4 IP Range (CIDR Block) and try „Create“:

In this article I will describe the installation of APEX Environment in Amazon Web Service (AWS).
The whole environment includes following components:
AWS RDS: Oracle Database with activated APEX VM (EC2 Container) with:
Oracle Rest Data Service (ORDS)
Apache Tomcat for the Hosting of the ORDS
The major challenge is to install APEX without SYSDBA privilege, because the Oracle Database in the RDS is Vendor-Managed. Users cannot access the OS and do not have the database DBA role.
Blue Print of the APEX environment in the AWS:
In my next Posts I will cover the following topics:
Create the APEX Database in Amazon Relation Data Service (RDS)
Configure APEX with Oracle Rest Data Service (ORDS) in the new EC2 Container
Configuration APEX with ORDS, Apache-Tomcat und Nginx
In my previous blog posts, I have described how to create the customer Oracle Database in the RDS with APEX Component:
In this post, I will explain the configuration of Middleware components needed to present apex content in web. We will build the separate VM (EC2 Container) in AWS and configure following components: ORDS, Apache Tomcat und Nginx Server.
Installing and Configuring the VM for the APEX Listener
Create EC2 Container for the APEX:

The operating system statistics are collected in the Exadata environment using the tool ExaWatcher automatically. You can generate statistics reports over a certain time as user root:
The following example generates the report for the period from 09/24/2018 till 09/26/2018:
./GetExaWatcherResults.sh –from 09/24/2018_00:00:00 –to 09/26/2018_23:59:59
Results will be generated as the BZIP2 Archive in the directory /opt/oracle.ExaWatcher/archive/ExtractedResults.
The results can be analyzed very simple via Browser. You can unpack the archive, go to the directory and see separate directories for the different statistics:

Some time I have the problem with the vies of the Top Activity Page in the Cloud Control:
The Graf shrink to left and you can see only the part of the picture:

Kernel-based Virtual Machine (KVM) provides a possibility to use the Oracle (or Redhat/CentOS) Linux kernel as a hypervisor.
In my example, I will configure the KVM virtualization on top of the guest vm running OEL 7.4. The guest VM is running on top of the VMWare Workstation 12.
To enable the virtualization layer select VM settings and navigate to the Processor settings. Enable the setting „Virtualize Intel VT-x/EPT or AMD-V/RVI.“
The Guest VM is now enabled for the using of the nested virtualization (such kvm). Start the Guest VM.
Install and configure KVM virtualization on the OEL 7.4 Linux
