The bug fixing support for Oracle Database 18.104.22.168 will end soon.
From my visits in the past months seeing some really large customer environments with easily over 1000 production databases each I can tell you that there may be many Oracle 22.214.171.124 installations out there. So maybe not everybody is aware of this fact.
It’s hard to believe but the Error Correction Support for Oracle Database 126.96.36.199 will end shortly on August 27,2015.
See MOS Note:742060.1 for further details.
And does it need to be said?
Yes, you can – of course – upgrade directly to Oracle Database 188.8.131.52.
