Pega Compatibility with AWS RDS - Oracle
Hello Folks,
We are planning to setup Pega in AWS with the following stack - Tomcat &AWS RDS Oracle. I would like to know the Pega platform compatibility with AWS RDS - Oracle.
- Does Pega/PRPC support AWS RDS Oracle? Has any Clients went with this setup in PROD?
- Does Pega require "Java" to be enabled in the Database either in the current or future versions of Pega?
- I could see the below dependency for enabling Java in DB -
- UDF's require Java to be enabled. Pega uses UDF's only in the reports rules where unexposed properties are used. The work-around for this is to expose the property, and this should address the problem. Are there any other scenarios where Pega uses UDF's and we do not have a workaround?
- AWS RDS does not support Java and UDF's. From the above point, this shouldn't be a show-stopper in moving away from AWS RDS to EC2. Are any Clients using this Stack - Pega + Tomcat + AWS RDS (Oracle/DB2), and is this supported?

Hello,
AWS RDS has one major issue, which is that Pega requires Java in the database to work and AWS RDS does not support it (per https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/CHAP_Oracle.html). Because of this, AWS RDS won't work for Pega, as we use a lot of Java in the database and Pega won't work without it - I believe it won't even install.
What does work is using a full AWS VM, where you can access the underlying OS - this has drawbacks compared to AWS RDS, but it will work if that's what you want. Or PegaCloud, if you're looking at multiple Cloud solutions and not just at AWS.

Hello Adam
Thanks for your response.
- With respect to your statement "AWS RDS has one major issue, which is that Pega requires Java in the database to work and AWS RDS does support it " - Is it a typo? Do you mean AWS RDS does not support it?
- "we use a lot of Java in the database and Pega won't work without it - I believe it won't even install" - What's the dependency of Java for Pega to run? The only dependency as per multiple forums over here are that UDF's require Java to enabled. UDF is only required for report definitions which uses unexposed properties. If we expose all the properties, the dependency on Java, UDF is gone? So do you still think Pega wouldn't work? By the way, I have setup an instance and it works fine. But I would like to know from the experts if there are are unforeseen issues?
- "What does work is using a full AWS VM" - Do you mean setting up EC2 and Oracle on top of it?

Sorry, typo - AWS RDS does not support Java in the database for Oracle. I've fixed the original post.
Java in the database is bit different per database type. It's possible it will run, but you might run in to problems in the future (other than UDFs as you already mentioned). I'm not certain exactly what needs Java - it's a bit out of my area. I'll see if I can find the answer.
Yes, setting up EC2 and Oracle on top of a full VM. Pega will work in a VM in general just like it does on an OS running on a physical machine.

Hi Adam,
Does PEGA need UDFs support to extract data out of BLOBs via BIX? In this case how did they get around with this? please help clarifying.

Here's how we do it for the PegaCloud solution:
In Legacy Cloud we use Oracle running on EC2 instances. In the "on-premise" world it would be just like spinning up a VM or standing up a physical server and installing Oracle on it. The app nodes handle all the Java functionality and "talk" to the database via jdbc. As Adam points out this will work, but is not as robust as an RDS cluster. We use it for All-In-One DEV instances that have an app node and an Oracle DB node on the same AWS instance.
In PegaCloud 2x we use Postgres running on Amazon RDS clusters. This solution is more robust and more easily managed than standalone servers. This is the optimal solution for PROD environments. We also actively develop PegaCloud and PRPC using this model so it is constantly improving.
As Adam also points out - you should consider implementing a PegaCloud solution that has all this taken care of for you. After the purchasing and onboarding happens - just paste the URL we provide into your browser and start developing.

Thanks for the notes. We are looking at Oracle as the DB. So do you think Pega would support Oracle on AWS RDS? Refer my questions related the dependencies and workarounds.

Since you are using Postgres in AWS RDS, Is Java enabled over there? How are you supporting UDF's?

(asked around...)
Oracle on RDS will work but the UDF's won't work. The good news is that they are not a required part of the product. As you point out, there is a workaround you can use.
For Postgres clusters in PegaCloud 2x we do not use Java within the database. We do use a special version of the UDF's that is supported by Postgres.

Hi Penng,
Thanks for the details. Where do we get that special version of UDFs that is supported by Postgres.
Complete details about Operating system, java version installed, Application server, Postgres DB with version.
Operating System : RHEL 7 (Red Hat Enterprise Linux).
Java version : Oracle 8U162
Application Server : Jboss EAP 7.1.0
Postgres DB : Postgres 9.6.5
Attached the Server Logs(when we are trying to import one of the FSIS package) and PL/Java Installation errors for your reference.

In my 3 tier architecture planning to have Web, App and DB. Application server will have RHEL 6.6 with Pega 7.2.2 and I am going to install/use Oracle 11g on AWS RDS.
Will there be any challenges. Can you share your expertise please ?
