We are trying to implement the following security to our database.
As of now, the access rights are same for all the windows users logging into the Oracle application with the same Oracle user Id.
But now, we want to improve our security by granting different levels of rights to the users based on their Network Id even though they use the same Oracle User Id to log into the application.
We are not looking for the users to be identified externally.
(CREATE USER "OPS$ORACLE-BASE.COMTIM_HALL" IDENTIFIED EXTERNALLY;
GRANT CONNECT TO "OPS$ORACLE-BASE.COMTIM_HALL";
)

ORACLE was working perfectly on Windows 7 since Jan 2010. A couple of days ago I ran a procedure which was to update a table with 1000 columns. The procedure worked fine till it created a few thousand records and then it slowed down terribly. I closed the SQL Plus command line tool (CTRL C) and tried to restart and then tried to logon to get the following errors-
ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
Then I used the Start Database tool (net start OracleTNSListener), but it showed "System 5 error". So after researching online I created Admin profile for WINDOWS 7 and logged in as an administrator. In the INIT.ORA file I increasd the SGA_TARGET to 5G and PGA to 3G. After doing that the above service is running but I'm still getting the ORA-01034 and ORA-27101.
Using cmd prompt in Windows and entering commands sqlplus -> Username: " / as sysdba" gives an insufficient privileges error.

according to article "Installing Netbackup for Oracle agent on Unix". URL.... Shut Down all oracle instances on this client. The reason: sometimes Oracle will take a shared library (such as ours) and place it into its shared memory spaceMy question is how I can control existence shared library in memory space to define the real need of Shuting down of all oracle instances ? I'm usung 11.2.0.3

There is a requirement in my database that I want to restrict the user from directly running queries on database from third party tools such as pl/sql developer and toad.
There is a utility in SQL product_user_profile through which this can be done but it is only restricted if you run the query through sql plus. If I want to restrict and (give suppose select,insert) to a user for directly running queries through PL/SQL.

I created an externally authenticated user in database. And can login without password with below syntax.
SQL> connect / @TESTDB
Connected.
SQL> show user;
USER is "SCOTT"
This scott user has a proxy permission to another DBuser PROXY_USER. Previously I used to login using below syntax.
connect scott[proxy_user]/password_for_scott@TESTDB
So now, what syntax should be used for this "ExternallY Authenticated" user to login as a proxy user?

- we have user id parameter.can we update the parameter(:parameter.p_userid) before firing "WHEN NEW FORM INSTANCE TRIGGER"(when new form instance trigger contain code for tree node), for login another canvas as per user rights?
- i have created a login form in one canvas.
- also tree node Hierarchy form created on another canvas. now we want to login through login screen, after login only those forms should show in tree Hierarchy which users have rights. for this purpose we want to pass the parameter of userid before connecting to tree node form through the following query
SELECT COUNT (*)
INTO v_count
FROM usersinfo
WHERE usersname = :USERBLOCK.usernames AND passwords = :USERBLOCK.passwords ;
[code]...
Every thing is working but when we click on button in login form at that time parameter.p_userid will return null. because above code is define on button click in login screen, i cannot understand where i need to define the above code .

When investigating memory usage on HP-UX V3 for my oracle database 11.2.0.3.4 which use AMM, it seems to me that system is not shifting shared SGA memory to private PGA memory when needed but it allocate other memory.The shared memory don't shrink all the memory_target id allocated. VSZ = RSZ
To test i have used this script which will allocate memory in process PGA.
create or replace package demo_pkg
as
type array is table of char(2000) index by binary_integer;
g_data array;
end;
[code]...
I have done the same test on a linux machine (Red Hat Enterprise Linux Server release 6.3) and the size of the POSIX shared memory switched (/dev/shm) to the PGA like demonstrated by Tanel Poder in his blog [URL]...

User A contains tables, views, LOB's, types, procedures, triggers, sequences, indexes, synonyms. User B wants to have read-only privilege on the objects of User A.
I can provide select on privilege on tables and views. How about providing read-only privileges to other objects?
