Refer to the Readme files prior to proceeding with these PSU implementations for important information that includes the supported paths per component, along with a full list of the defects fixed, additional support information, prerequisites, details for applying patch and troubleshooting FAQ's. It is important to ensure that the requirements and support paths to this patch are met as outlined within the Readme file.
The Readme file is available from the Patches & Updates download screen for each of the Hyperion Essbase components.
Caution: Oracle recommends using the same version of all Essbase portfolio products (Essbase, Essbase Administration Services, Hyperion Provider Services, and Essbase Studio) and components (server, client, runtime client, API, and JAPI). When only some Essbase portfolio products are included in a patch release, the last released versions of the products that are not included in the patch are supported.
Essbase Administration Services 184.108.40.206.037, Provider Services 220.127.116.11.041, and Essbase Studio 18.104.22.168.031 are supported for use with Essbase 22.214.171.124.041. Furthermore, Essbase Runtime Client needs to be updated on systems that Essbase Administration Services is installed starting with this patch.
Recommendation: After you apply a patch within the same release codeline, Oracle recommends as a best practice that you export the data from your databases, clear the data from the databases, and then reload the data.
