Symptoms

When a session is inactive, the SQL_ID for this session is not null.

The issue can be reproduced by following these steps:

- connect from sqlplus as a test user

- connect from a second session as sys and run the following query:

SQL> select sid, username, status, sql_id, sql_exec_start from v$session;

Note: the first session should should be inactive and having SQL_ID NULL

- go back to the first session and run a query

SQL> select * from dual;

- go back to the SYS session and verify again the sessions

NOTE: the first session will show again as INACTIVE but this time the SQL_ID has an explicit value

-- First session

SQL> conn scott/tiger
Connected.
SQL> create table test1(id number);

Table created.

SQL> select * from dual;

X

-- Second session as sysdba

SQL> select sql_id,status from v$session where username='SCOTT';
