User Schema

Question

Hi,
select schemaname into schema_id from V$session where audsid = userenv('sessionid');
Iam using the above query in the after logon on database trigger (in the sys schema), but it does not give the right schema name, who ever logins to any schema in the db, the above query in the trigger o/p's schema name as 'SYS'. Anyone help me in this.
Thanks & regards

Answer 1

what is your need exactly, are you auditing the logons? also "schemaname into schema_id" sense not good.
CREATE TABLE connection_audit (
login_date DATE,
username VARCHAR2(30));
-- trigger to trap successful logons
CREATE OR REPLACE TRIGGER logon_audit
AFTER LOGON
ON DATABASE
BEGIN
INSERT INTO connection_audit
(login_date, username)
VALUES
(SYSDATE, USER);
END logon_audit;
-- trigger to trap unsuccessful logons
CREATE OR REPLACE TRIGGER logon_failures
AFTER SERVERERROR
ON DATABASE
BEGIN
IF (IS_SERVERERROR(1017)) THEN
INSERT INTO connection_audit
(login_date, username)
VALUES
(SYSDATE, 'ORA-1017');
END IF;
END logon_failures;
other errors that could be trapped include:
ORA-01004 - default username feature not supported
ORA-01005 - null password given
ORA-01035 - Oracle only available to users with restricted session priv
ORA-01045 - create session privilege not granted
