Since Release 1 update 7 (24.1.0.7) patch you may get the error “<Server_name> redirected you too many times”.
This is a known bug of this release update due to certificate in browser. There is a bug opened at oracle for this issue.
As a workaround whil we wait for the patch, you can run
emctl set property -name oracle.sysman.core.security.auth.disableZDTUi -value trueNo need to restart the OMS. You’ll need to clear cookies and stuff from the browser.
