Patch 26559378: Essbase Analytic Provider Services
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 22.214.171.124.020, Provider Services 126.96.36.199.020, and Essbase Studio 188.8.131.52.016 are supported for use with Essbase 184.108.40.206.020.
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.
