JDBC Application Generates DB Performance Problems Showing A Lot Of Executions of dbms_utility.get_tz_transitions() Package (Doc ID 1460112.1)

Last updated on AUGUST 03, 2016

Applies to:

JDBC - Version 11.1.0.6 and later
Information in this document applies to any platform.

Symptoms

A JDBC application experiences intermittent periods of severely reduced throughput, not necessarily associated with any external factors. Database profiles reveal that a large amount of time is spent servicing requests for execution of dbms_utility.get_tz_transitions(). The timezone setting in the client JVM is reasonable (that is, it is a timezone known to the Oracle database), so improper timezone setting is not the cause.

Changes

 In a security hardening exercise the package dbms_utility, which normally has public access, had its access restricted.
