We share our skills to maximize your revenue!
One of the annoying things about our industry is the volume of acronyms and very specific terminology used on a day-to-day basis. If you know the lingo you are fine. If not, life can be quite problematic.
In some cases, this is just a smoke screen to hide a lack of true understanding, say enough buzzwords you read in a Gartner report and people will eventually stop asking you to define them, but in other cases it is necessary to be able to communicate *accurately* about complex issues at a reasonable pace.
Some people are completely anal about everything, demanding an incredibly high degree of precision and exact terminology. Deviate from their prescribed ideal and you are in a world of hurt. Others, like myself, allow a lot more slack, knowing that every person is on a different part of the spectrum where this is concerned.
The problem with letting people get away with loose terminology and a lack of accuracy is it can sometimes come back to bite you on the ass. It’s all too easy to let them walk away with an unrealistic view of the situation, that becomes the new office myth, and travels with them through every company they ever work in…
- Person: So Oracle does this right?
- Me: Not really. It’s a lot more complicated than that. It’s more accurate to say it does …
- Person: Yes, but it amounts to the same thing. It basically ends up doing this right?
- Me: No. It really doesn’t. I can see how it appears that way in this case, but that’s too simplistic a view.
- Person: Yeah, yeah. I know, but for the sake of argument, we will say it does this, which results in …
- Me: Fine. That’s wrong, but lets leave that aside and move on…
… One week later …
- Person: So I discussed this with Tim last week and he agreed that …
- Me: I will look for you, I *will* find you, and I will kill you!
I’m sure you’ve all been there at some point. It can be a really fine line between getting something across properly and being a total douche. Too far one side of the line and people are walking around believing rubbish. Too far the other way and you end up excluding people and sounding like an elitist prick.
It’s a journey babe!

We are going to go through the tutorial for installing EBS on IaaS for this blog. We are going to go down the multi-node install which first requires installing the provisioning tools to boot all of the other images into standalone instances. We will need at least four compute instances with 500 GB of disk storage to deploy our test. The individual requirements are shown in the diagram below.
Before we can start deploying we must first go to the Oracle Cloud Marketplace and download five EBS bootable images. We start by going to the marketplace and searching for "e-business" images. A list of the images that we need are shown in the diagram below.
Step 1:Download EBS 12.2.5 Fresh Install DB Tier Image. This is done by selecting the image that is returned from the search. When we get to the image page we click on "Get App". This brings up a usage terms screen that we need to click on and click OK. Once we have accepted the terms we are presented with a list of cloud instances that we can deploy into. If you don't see a list of servers you need to go into your preferences for your instance and click the checkbox that allows you to provision the marketplace apps into your instance. You will also need Compute_Admin roles to provision these boot images. You don't need to go to the compute instance after you download the image. You are mainly trying to copy the DB Tier Image into your private images.
Step 2:Download EBS 12.2.5 Demo DB Tier Image. Unfortunately there is no go back feature so you need to go to the marketplace page, search again for e-business, and select the Demo DB Tier Image.
Step 3:Download EBS 12.2.5 Application Tier Image.
Step 4:Download EBS OS-Only Image
Step 5:Download EBS Provisioning Tools Image
Step 6:Verify that all of the images are ready. You should get an email confirmation that the image is ready. You should also be able to create a new instance and see the images in the private images area. You should have five images available and we could create a bootable instance for all of them.
Step 7:Create a compute instance using the Provisioning Tool image. We are going to go with an OC3 instance and accept the default. We will create a new security list and rule that allows http access. We do have to select the boot image from the private image list.
You get to review this before it is provisioned.
This will create an Orchestration that will create the bootable disk and boot the instance. It will take a few minutes to do this and once it is done we should have all of the provisioning tools ready to execute and deploy our multi-node EBS instance.
Step 8:Connect to the server via ssh using opc. Get the ip address from the previous screen. When I first tried to connect I had to add default to the Security List otherwise the connection timed out. Once I added the ssh rule, everything worked as expected.
Step 9:change user to oracle and execute
knife oc image list
You will need the compute endpoint of the compute service because you will be prompted for it. To find this you need to go to the Compute Dashboard and look at the Compute Detail. The RESTapi Endpoint is shown but for our instance we need to change it a little bit. We have two zones associated with this domain. We want to connect to the z16 instead of the z17 zone. Once we enter the endpoint, identity domain, account id, and account password, we get a list of images that we can boot from. At the bottom of the list we see the EBS images and should be good to go. It is important to repeat that using the z17 zone will not show the images so we had to change over to the z16 zone. This is due to a Marketplace configuration that always deploys images into the lowest numbered zone for your instance.
Step 10:Edit /u01/install/APPS/apps-unlimited-ebs/ProvisionEBS.xml and replace the id-domain and user name with the output of the knife command. It is important to note that your substitute command will be a little different from the screen shot below. I also had to change the OS-Image to include the date otherwise the perl script that we are about to execute will fail as well. The file name should be /Computefirstname.lastname@example.org/Oracle-E-Business-Suite-OS-Image-12032015 but your instance and user will be different.
Step 11:Run perl /u01/install/APPS/apps-unlimited-ebs/ProvisionEBS.pl to start the install. This will ingest the xml file from the previous section and present you a menu system to install the other instances. The system will again ask for the restAPI Endpoint for the compute server, your restAPI Endpoint for storage (go to Dashboard and click on Storage to get this), your identity domain, account, and password again. For our test installation we selected option 3 for a multi-node single application server installation. The perl script then installs chef, pulls cookbooks, and installs the database, app server, and forms server instances into compute instances. This step will take a while. I recommend playing around with all of the options and configurations until you get comfortable with what you are installing. We were going for the demo installation rather than a dev/test installation. We went for a single app node and a single database node. We could have gone for multiple app nodes and gone with demo or dev deployments. Some of the screen shots from this process are below. We called our installation prsEBS so if you see references to this it relates to our installation. The process deploys orchestrations to the cloud services then starts these services in the Oracle Cloud.
We can confirm that this is doing what is expected by looking at the Orchestration page under the compute console.
When it is complete we will see four instances are running in compute.
In summary, we are able to provision multiple instances that comprise a single application, E-Business Suite. This process is well documented and well scripted. Hopefully these screen shots and steps help you follow the online tutorial mentioned earlier. What is needed next is to apply the security principles that we talked about in the past few days to secure the database and hide it from the public.
