Patch Today! Don’t Delay! Best Reasons to Upgrade Your EPM System

Putting off that upgrade to 11.1.2.4? Cloud not whetting your appetite for patches? Patch today. Don’t delay!

“But we’re going to the Oracle EPM Cloud soon!” you say. You should maintain your patches anyway. With the recurring maintenance, updates, and patches available to the EPM Cloud products, expect the on-premise patches to contain similar updates. An upcoming conversion to Oracle EPM Cloud products may benefit from running the latest on-premise codelines.

If you have an existing on-premise installation of Oracle EPM System, be sure to maintain the latest EPM System Patch Set Updates every 3 to 6 months. Here are a few great reasons why:

New Features

Patches often contain reactive bug resolutions to known issues; however, we have also been seeing new functionality released in patches for 11.1.2.4.

You Own It

You already pay for it! As long as your Oracle Maintenance contract is current (very likely if you are reading this article), you’re already paying for access to patches. Why leave them unapplied? You are running legacy code when the latest version costs you nothing additional. Windows XP was a great OS, but we’ve got to keep up with the times.

Supportability

Maximize your success by reducing time to resolution on your issues. Should you submit a support request to the vendor, the first line of response to a ticket is often about current patch levels. Once provided, the subsequent reply frequently contains a recommendation to apply the latest Patch Set Updates (PSUs) to see if that fixes the issue. Annoying? Perhaps you’re a pessimist. Or have just been remiss with your patching. I’ve certainly changed my mind on the matter and can better side with them. The reason? Supporting the latest codeline is more efficient and effective for the vendor. Your problem may have already been addressed in a code fix. They can better and more quickly support you if they are troubleshooting the current release instead of legacy code.

Stability

In older versions, patches seem to come out on a haphazard schedule. Over the last few years, Oracle has regularly streamlined EPM System patch releases – typically releasing Patch Set Updates quarterly, which are different from Patch Set Exceptions. PSUs are a grouping of PSEs or fewer, more significant PSEs that get regression tested collectively by the vendor and are released under a singular patch. We’ve gained a much higher degree of confidence with this bulk model of PSUs. The organization of release schedule and bug fixes is more dependable and greatly appreciated. The PSU model provides less ambiguity on which patches to apply and brings greater stability to all customers.

Upgrade

Maybe it’s bigger than patching. Are you not on version 11.1.2.4 of your EPM System? Compliance with Enterprise IT requirements around browser version and operating systems is often impetus for an upgrade. But there are also plenty of compelling new software features, functions, conventions, and improvements in 11.1.2.4.

Operating System (OS) support for current platforms maximizes your investment and supportability. When 2.4 came out, many customers were forced to upgrade their older systems for compliance with the latest enterprise standards for server operating systems and/or client browser versions. Instead of being faced with an IT mandated technology upgrade, an upgrade on the business’ schedule is preferred.

What Kind of Effort is Involved?

The comprehensive effort to bring a simple deployment (3-4 servers, no High Availability) up to the latest PSUs is typically less than a day per environment. That includes an analysis of existing patches, the patching itself as well as any prerequisites, and a post-check verification to confirm all patches applied are properly indicated in the corresponding inventories.

An initial patch application may take a little bit longer because there are often common prerequisites to address that don’t have to be handled with subsequent patching. There are also considerations like bringing WebLogic up to the latest patch level, as well as one-offs like the fixes for the Equifax-discovered vulnerabilities, that don’t happen frequently. Once you’ve got a solid base of primary critical patching, additional patching events are typically shorter.

Patching can be tricky. Documentation can often be ambiguous, whether it be an unintended omission or even assumed knowledge based on an implied experience or understanding of the product. Sometimes post-install instructions get skipped or SQL statements do not get executed properly as part of the patch. Less experienced resources typically only patch the EPMSystem11R1 Oracle Home; however, did you know that Oracle’s ADF framework also has an Opatch directory under oracle_common? Possibly because those are often prereqs. But what about Oracle Data Integrator (ODI) and Oracle HTTP Server (OHS)? They also may have applicable OPatches. Who knows what you’re missing? We do!
