Performance issue after upgrade to ORDS 21.1
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?

Recommend you downgrade ORDS to 20.4...that statement isn't the best, it's been corrected for ords 21.2
Also, your DB is out of support as of end of June (18c) - consider upgrading that to 19c, and your APEX is also old...

Hi,
I have the same problem, in Oracle Atonomous DB.
-
right, it's the same ORDS with the same problem - we'll be staging a fix via an ords 21.1.3 ASAP for both Cloud and for Download

Hi,
Oracle Apex is some slow responding? I have installed apex 21-1 on DB 12-1-0-2-0 with ORDS 21-1-3-r1531102
can anyone advise about its performance tuning?
-
Same issue with ORDS 21.1, Oracle 19c, and Tomcat 9. Can anyone confirm this issue is resolved by updating to ORDS 21.2?

Yes, issue is resolved in version 21.1.3 or newer
