Oracle MTS Recovery Service for 11g Is Removed by 12c Deinstallation (Doc ID 2659110.1)

Last updated on APRIL 17, 2023

Applies to:

Oracle Database - Enterprise Edition - Version and later
Microsoft Windows x64 (64-bit)


If an environment consists of two releases, one is 'Oracle Database 11g' (or previous release as well) and the other is 'Oracle Database 12c' (or following release as well), then deinstalling the latter (12c) will also remove 'Oracle MTS Recovery Service' for the former (11g).

This problem can reproduce by the following steps for example:

  1. Install Oracle Database and configure 'Oracle MTS Recovery Service'
  2. Install Oracle Database
  3. Deinstall Oracle Database


Do the deinstallation for 12c when 11g still has been installed.
