I use following sql to create my trigger
CREATE OR REPLACE TRIGGER INSERT_LOG
AFTER INSERT
ON EXTERNAL_SCHEME.PAYMENT
FOR EACH ROW
BEGIN
INSERT INTO MY_SCHEMA.DM_LOGGER(ID, TECHNOLOGY, WORKFLOW, NAME_EVENT, TIME_EVENT)
VALUES (PAYMENT.id, 'Repository', 'UP', (select repo.name from
pay_repository repo join pay_pmt pay on repo.id = pay_pmt.repository_id
where repo.id = pay.repository_id),(select to_char(SYSDATE, 'hh24:mi:ss') from dual));
END;
When I execute this trigger I get following exception:
01031. 00000 - "insufficient privileges"
*Cause: An attempt was made to change the current username or password
without the appropriate privilege. This error also occurs if
attempting to install a database without the necessary operating
system privileges.
When Trusted Oracle is configure in DBMS MAC, this error may occur
if the user was granted the necessary privilege at a higher label
than the current login.
*Action: Ask the database administrator to perform the operation or grant
the required privileges.
For Trusted Oracle users getting this error although granted the
the appropriate privilege at a higher label, ask the database
administrator to regrant the privilege at the appropriate label
I don't get it. I have connection to both schemes and I never want to change something. What is wrong?
the privileges seems to be missing,please execute,
grant create trigger to schemaname;
if it still gives the error then the select privileges might be missing on the tables of other schemas, for that you can run this,
grant select on otherschema.table_name to <schema_name> ;

I am hunting down failed Oracle logins - ORA-01017 invalid username/password errors - and i cannot find them in the alert_SID.log file. I do see other ORA-* errors. Are ORA-01017 errors not logged by default? I am reading about configuring auditing, but would think that unsuccessful logins would be logged automatically. This is for an Oracle 11.2g database and an Oracle 19.0c database.
I had a similar issue. So many people using the same database users, sometimes someone was entering wrong the password so many times that it locked the user. ORA-1017 are not audited by default, neither logged. You either enable audit or you create your own logon trigger for this, which was what I did
To audit that operation, I designed this trigger
CREATE OR REPLACE TRIGGER SYS.logon_denied_audit AFTER SERVERERROR ON DATABASE
DECLARE
l_message varchar2(2000) := 'ORA-1017: Invalid username/password: logon denied';
BEGIN
-- ORA-1017: invalid username/password; logon denied
IF (IS_SERVERERROR(1017)) THEN
insert into my_audit_table
(
RAC_INSTANCE ,
SERVICE_NAME ,
SESSION_ID ,
ORACLE_USER ,
OS_USER ,
TERMINAL ,
PROGRAM ,
ACTION_TIME ,
ACTION ,
IP_ADDRESS ,
CLIENT_IDENTIFIER ,
ERROR ,
IS_LIMITED
)
values
(
SYS_CONTEXT ('USERENV', 'INSTANCE'),
nvl(UPPER(SYS_CONTEXT ('USERENV', 'SERVICE_NAME')),'Service Unknown') ,
9999 ,
SYS_CONTEXT('USERENV', 'AUTHENTICATED_IDENTITY'),
UPPER(SYS_CONTEXT('USERENV', 'OS_USER')),
nvl(SYS_CONTEXT ('USERENV', 'HOST'),'Unknown Host'),
nvl(SYS_CONTEXT('USERENV','MODULE'),'Module unknown'),
systimestamp,
'LOGON',
nvl(sys_context ('USERENV', 'IP_ADDRESS'),'Unknown IP'),
null,
l_message ,
'N'
);
end if;
end;

Thereby, I can log unsuccessful attempts to login in the database. By the way, it works the same in 11g than in 19c
In general, configuring auditing is the preferred way to go with this. You can create a custom trigger, but I believe they are less reliable and more likely to be compromised than Oracle's built-in method for tracking. Additionally, custom security objects should should always be placed in a dedicated schema. Never create custom objects in the SYS schema.
I wrote a blog recently on basic auditing configuration entitled "Auditing By The Numbers". You can also find resources here: https://oracle-base.com/articles/8i/auditing. The easiest way to enable auditing (assuming you're in Oracle 12c or later) for logins would be the following, executed as a user with DBA or SYSDBA privileges:
-- audit all user logon and logoff attempts:
create audit policy stig_user_logon_actions actions logon, logoff;
audit policy stig_user_logon_actions;
For Oracle 11g:
alter system set audit_trail=DB scope=spfile;
[restart database]
audit create session;
Then look at your audit trail in the DBA_AUDIT_TRAIL view, or DBA_AUDIT_SESSION (11g).
I have 2 schemas:
ARIEL
ARIEL_APEX
All the tables in ARIEL are accessible to ARIEL_APEX and the queries run OK from the ARIEL_APEX schema.
For example,
SELECT * FROM ARIEL.DIM_REGISTRATION_SET
works fine from the ARIEL_APEX schema.
When I try to create a view in ARIEL_APEX:
CREATE VIEW TEST_VIEW AS
SELECT * FROM ARIEL.DIM_REGISTRATION_SET
I get this:
Error at Command Line : 465 Column : 23
Error report -
SQL Error: ORA-01031: insufficient privileges

This works absolutely fine in the test and production environment, this is development. DBA saying all is well at their end.
ARIEL_APEX having below privileges.

And we know the grants are OK on the ARIEL objects to ARIEL_APEX as we can execute the query manually.
This is Oracle 12. Never had the issue before we upgraded, but suspect this is related to accessing objects from another schema within a view.
ARIEL_APEX is a member of the ANALYTICS_ROLE, the ANALYTICS_ROLE grants select on all tables in the ARIEL schema, which can be seen to working below.
Works in upper environments, only difference is grants provided by a role...in other environments SELECT grants provided directly on objects.
As noted in the documentation (emphasis added):
The owner of the schema containing the view must have the privileges necessary to either select (READ or SELECT privilege), insert, update, or delete rows from all the tables or views on which the view is based. The owner must be granted these privileges directly, rather than through a role.
If you only have the select privileged on the underlying table granted through a a role then you cannot create a view against it. Even if you move to role generally, you'll have to keep explicit grant on top for any views you want to create.
I imagine this is to do with how roles work. With a direct grant Oracle knows whether you can see the table in the other schema. If you grant select on your view to someone else then when they query the view Oracle knows that the chain of privileges is there. If your direct grant on the table is revoked then there are mechanisms to invalidate dependent objects. But what should happen the role's select privilege on the table is revoked; or your access to the role is revoked; or just within your own session, what should happen if you disable that role - can you still access the view? It's a bit more complicated that it seems at first glance.
Fortunately creating views should be relatively rare and controllable. Most people accessing the table via the role won't need to create a view on it (I assume!).
Another option here is create the view in the ARIEL schema, and then grant privileges to APEX_ARIEL and/or a role. Whether that is appropriate depends on your real view query and your motivation for creating the view.
I have two schemas, let's call them BOB and FRED. I need to call a table in schema FRED from schema BOB to use the primary key in that table as a foreign key. I've set up the appropriate grants for schema FRED to allow BOB access to it, but whenever I run the script, it complains that I do not have the correct permissions. Is there another setting that I need to change somewhere? Can this even be done?
My FK creation is as follows:
ALTER TABLE "BOB"."ITEMGROUP" WITH CHECK ADD CONSTRAINT FK_ITEMS_ITEM FOREIGN KEY (ItemID)
REFERENCES "FRED"."ITEMS"(ItemID)
And I'm doing the grant with:
GRANT ALTER ON "FRED"."ITEMS" TO "BOB"
I get this error message:
SQL Error: ORA-01031: insufficient privileges
01031. 00000 - "insufficient privileges"
*Cause: An attempt was made to change the current username or password
without the appropriate privilege. This error also occurs if

*Action: Ask the database administrator to perform the operation or grant
the required privileges.
For Trusted Oracle users getting this error although granted the
the appropriate privilege at a higher label, ask the database
administrator to regrant the privilege at the appropriate label.
You need to:
grant references on "FRED"."ITEMS" TO "BOB"
See this "AskTom"
To create a foreign key referencing a table in another schema you need the "REFERENCES" privilege:
GRANT REFERENCES ON FRED.ITEMS TO BOB;
One of our cutomer is running the scripts in oracle sql developer to upgrade his database table structure, procudere & triggers etc. But while running the script, he is getting ORA-00904: Invalid Identifier Error for DBMS_LOB.SUBSTR() and DBMS_LOB.GETLENGTH() in one procedure.
Can somebody tell why is happening so?
There are using Oracle Sql developer Version 3.1.07 Build MAIN-07.42 with Oracle 11g.
I imagine 3 possible reasons:
the user lacks execute privilege on sys.dbms_lob (although the
privilege is granted to PUBLIC by default)
there is no synonym dbms_lob for sys.dbms_lob in the database (although such public synonym should exist)
the schema, on which the customer works, contains some other package with the same name DBMS_LOB
Run this sql with sys to check whether your schema has privilege to execute DBMS_LOB.
select * from dba_tab_privs where table_name='DBMS_LOB';
By default, you should see PUBLIC in the grantees.
If not, you can run sql with sys.
grant execute on sys.DBMS_LOB to public;
or
grant execute on sys.DBMS_LOB to <your_schema_name>
i was running an insert query on a synonym i got ORA-01031 in sql developer, we are accessing almost all tables through synonym only, but only this one in the schema gave ORA-0103 error. Please guide.

did you execute something like:
GRANT select, insert, update, delete on Table to your_synonym_user;
and this line should be executed by the Table owner or the user with that permission.
It looks very much like the permissions you have to either the underlying table, or the synonym are insufficient, or possibly that your password has expired?
