OEM 13.5 RU 21 and WLS PATCH SET UPDATE 12.2.1.4.240325
We have had issues with OEM 13.5 after the combination of release update RU 21 and WLS PATCH SET UPDATE 12.2.1.4.240325.
It has broken the functionality of all metrics section in the OEM with ADF_FACES-60097 And ADF_FACES-60096 Errors . It was identified with the Oracle Support that the WLS Patch Patch 36440005: WLS PATCH SET UPDATE 12.2.1.4.240325 is not certified for OMS 13.5 RU 21.
Please use the earlier Patch 36155700;WLS PATCH SET UPDATE 12.2.1.4.240104 with RU 21.
Hope this helps anyone having similar issues.
Thanks
