TitleInvalid Query issued by Oracle JDBC driver v5.1 causing Oracle Log pollution
URL Nameinvalid-query-issued-by-oracle-jdbc-driver-v5-1-causing-oracle-log-pollution
Article Number000171463
EnvironmentProduct: Connect for JDBC Oracle Driver
Version : 5.1.4.000466
OS: JAVA
Database : Oracle 12.1.0.2
Application: All supported applications
Question/Problem Description

Each time a connection to Oracle database is made using DataDirect Oracle JDBC driver, it was observed that , the driver is executing the following query:
SELECT SYS_CONTEXT ("USERENV", "CLOUD_SERVICE") FROM DUAL;  which results in the ORA-02003 error.

But this execution of the query and the resulting error does not show up in the Spy log.
But it shows up in the Oracle log file on the database side.
One client application makes around 600,000 new connections to the Oracle database per day.
And the Oracle log file gets filled with 600,000 ORA_02003 errors per day causing a huge logging overhead.
It does not break anything in the client application workflow. 

Is there anyway to stop this invalid query being executed by the driver each time you try to connect to the database?

Steps to Reproduce
Clarifying Information
Error MessageORA-02003: invalid USERENV parameter
Defect NumberEnhancement
Enhancement Number
Cause
The driver uses this query to determine if the Oracle server to which it's connected is an ADW/ADWC (autonomous data warehouse) server.
This query is a part of its connection establishment process. Based on the result of this query, the driver makes some internal adjustments which
have an effect on a few pieces of DatabaseMetaData and the way in which transaction isolation levels are changed by the driver.
