Hyperion Essbase Server 188.8.131.52.021
Patch 26835562: Essbase Server
Hyperion Essbase Client 184.108.40.206.021
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 220.127.116.11.020, Provider Services 18.104.22.168.020, and Essbase Studio 22.214.171.124.016 are supported for use with Essbase 126.96.36.199.021.
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.
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.
