Performance issue after upgrade to ORDS 21.1

andy.vMay 26 2021

Hi.
We have performance issue after upgrade from 20.4 to 21.1 version. ORDS is only used for APEX applications.
RDBMS Version 18.5, RAC, 2 nodes. APEX version 19.2.
In version 21.1 ORDS executes on every request sql : "SELECT COUNT(1) FROM SYS.ALL_SYNONYMS WHERE OWNER = 'PUBLIC' AND SYNONYM_NAME = 'APEX_RELEASE' AND TABLE_NAME = 'APEX_RELEASE'"
In our environment, this request takes about 2-3 seconds, so if there are several hundred active users, everything hangs...
We have created SR regarding the performance of a query to the system dictionary, but there is no solution yet.
What recommendations can be in this case?
