How to Set V$SESSION Properties Using the JDBC Thin Driver (Doc ID 147413.1)

Last updated on MARCH 12, 2024

Applies to:

JDBC - Version 9.2.0.1 and later
Information in this document applies to any platform.

Goal

This sample illustrates how to set V$SESSION properties upon connection using the JDBC Thin driver.
The sample queries the table to confirm that the property has been set.

Note: The JDBC Thin driver cannot correctly retrieve the values of some V$SESSION properties on its own. Specifically, the driver exhibits the following behavior:

  • When querying the TERMINAL field of the V$SESSION table using the JDBC Thin driver, the value returned is "unknown".
  • When querying the PROCESS field of the V$SESSION table using the JDBC Thin driver, the value returned is "1234". The driver returns the process ID as "1234" by default, since obtaining a process ID is not possible using the JDBC Thin driver.

Therefore, for an appropriate terminal name or process ID to be returned to the JDBC Thin driver, these properties may be populated using the method described below.

This specified example sets and queries the PROGRAM field of the V$SESSION table; the TERMINAL or PROCESS fields of this table can be set from this example by uncommenting the appropriate lines of code.

This same syntax can be used to set any field in the V$SESSION table.

The following method apply to the JDBC Thin driver; the JDBC OCI driver calculates some fields, such as PROGRAM and OSUSER, differently from the JDBC Thin driver.

Note: This method setting the values of properties such as V$SESSION.OSUSER, and other V$SESSION properties, involves no validation or authentication. This approach should not be used as part of any security framework, since it can be used to set these properties to arbitrary values.
