UPDATED! EM 13.5 Requires a Repository in a 19c RU11 Database, RU1 Requires More
For Enterprise Manager 13.5 Cloud Control, the only certified database version for the repository is 19c with RU 11.
If you have already installed and/or upgraded to EM 13.5 with a 19c repository database at an RU level below RU11, then apply the RU 11 patch.
If your reprository database is at a lower version than 19c, you are advised to upgrade that database to 19c RU11 before installing or upgrading to EM 13.5.
Addendum:
In preparation for application of RU1 to an EM 13.5 system, the user must additionally patch the required 19c RU11 repository database with Patch 17777718. This prerequisite repository database patch is necessary for successful application of RU1 on the EM 13.5 system for both non-ZDT and NZDT based patching.
