Different Behaviors When Querying Various V$ Views From Application Root

(Doc ID 2398776.1)

Last updated on MAY 15, 2018

Applies to:

Oracle Database - Enterprise Edition - Version 12.2.0.1 and later
Information in this document applies to any platform.

Symptoms

The symptom is seen when using 12.2 new feature "Application Container".

When querying views like v$lock or v$session from Application Root,
the query returns rows from con_id 0 and the Application Root's con_id.

However, when querying v$latch, rows from application root and
the application PDBs are queried. con_id=0 is not shown.

 

Changes

The issue is seen when querying v$latch from inside Application Root.
