With more and more folks migrating Oracle EPM 22.214.171.124 / Hyperion from on-premises data centers to 3rd-party hosted environments, the topics of Secure Socket Layer (“SSL”) and support for TLS 1.2 are becoming much more common conversations.
The devil, of course, is in the details.
As a matter of policy, many 3rd-party hosting companies and/or IT departments are disabling SSL protocols 2.0, 3.0, TLS 1.0, and TLS 1.1 by default. Security vulnerabilities for those older protocols are to blame. This leaves us with TLS 1.2 as the preferred option for SSL.
The problem, though, is EPM 126.96.36.199 uses Oracle HTTP Server (“OHS”) 188.8.131.52 under the covers, and guess what? OHS 184.108.40.206 cannot support any TLS protocol higher than version TLS 1.0.
But wait! Isn’t EPM 220.127.116.11 certified by Oracle to use Microsoft IIS 8.5 as the web proxy, which supports TLS 1.2? Yes, indeed it is. But, the SSL configuration documentation for EPM 18.104.22.168 is OHS-centric; the IIS-related matters are incomplete and several important configuration details are missing in various blogs and Knowledge Base articles. Case in point: manual edits required for iisproxy.ini are completely missing in the EPM-centric documentation currently available as of this writing.
This brings us to the Oracle Knowledge Base article,“How To Update OHS 22.214.171.124 In EPM System To 126.96.36.199 (Doc ID 2406726.1).”
July 4, 2018 update: The Knowledge Base article mentioned above is no longer available to Oracle customers; the KB is now flagged as Oracle internal-only. I’ll write a new blog post that explains why I believe this is so, and what you can do if you’ve already upgraded from OHS 188.8.131.52 to 184.108.40.206, and one or more EPM modules are now non-functional.
This article provides steps on how to perform an in-place upgrade from OHS 220.127.116.11 to 18.104.22.168 for EPM 22.214.171.124. Oracle certifies that OHS 126.96.36.199 supports the TLS 1.2 SSL protocol. The procedure to upgrade OHS is easy to follow.
But, there’s a catch, and this is the point of today’s blog post.
OHS 188.8.131.52 and Hyperion Calculation Manager 184.108.40.206 do not play well together! After applying the OHS 220.127.116.11 in-place upgrade, attempting to login to Calculation Manager 18.104.22.168 results in a blank tab in EPM Workspace. There are no blog posts or Knowledge Base articles on how to fix this…. until now!
The fix is buried within the release notes for the EPM Shared Services patch 22.214.171.124.500.
July 4, 2018 update: The information below is obsolete. I’m keeping it online for historical reference purposes. Simply apply Calculation Manager patch 126.96.36.199.013 or higher. This fixes the regression bug, and you don’t need to execute the instructions listed below.
Open a command prompt and CD to your Oracle EPM Instance home’s \bin folder on any of your Hyperion servers. The default location for this is: D:\Oracle\Middleware\user_projects\epmsystem1\bin for most Microsoft-based systems. UNIX nerds like me, you know the drill! (Swap the direction of the slashes)
Paste this command:
epmsys_registry addProperty /CALC_MANAGER_PRODUCT/@BINDOWS_ENABLED true
Then restart the Calculation Manager service, and you’re good to go.
What you’ve just done is gone back in time to the 188.8.131.52.0 days and instructed Calculation Manager that it should not use the 184.108.40.206.500+ Application Development Framework (“ADF”) interface, with which apparently OHS 220.127.116.11 has an issue.
Hopefully, Oracle will issue a future patch to remediate this; until then, carry on and be safe out there!
