Security in data base oracle

Hello!
Since I can do so that from a client (host) single oracle is connected to the data base from my applications, and not can connect from another programs to the data base the PC client

You can use 'proxy authentication' such that they must log in through the application, although if the app is on their machine they could get to that password.
You can create an after login trigger that will look at such things as their program name to prevent a user from logging in with SQLPlus / Excel and kick them out if they come in the wrong way.
You can prevent them from doing anything by having the application utilize a Secure Application Role, such that if they login outside of the application they cannot read/write the application tables.
If the application lives on a users host then they can (with effort) get around all of these. If the application lives on a host outside their control then you can completely stop them from accessing the database.

Data base oracle in SAP

Hi,
The combination of all dimension id's ideally make the primary(composite) key of the fact table.
it seems that there is a database restriction of 16 fields to be combined to make a joint primary key.
I heard that Oracle table join relation is the restriction of 16. I mean foregn key relations from a table ( fact table ) can not exceede 16. and thus we have 16 dimensions as the restriction..
It is ORacle limitation.. ( data base )
Any data base can not have more than 16 Fields as primary key in a table and hence 16 dimentions as MAX limit..for our facttable / cube.In database tables level we have only 16 primary keys, thats the reason why we hav 16 dimensions in infocube.
( remember oracle is the database we use for SAP ).

Yes, you understand the issue. Not sure about all the other DBs, I think they have 16 column index limits as well. Even if one of them would support more columns in the index, I doubt SAP would reengineer the BW to support them, until/unless that DB had a major portion of the BW installations.

Problem of security using ADO from Labview to connect to Access 2000 Data Base

I have a problem using ADO from Labview to connect to Access 2000 Data Base.
First I open a ADO_DB_Engine and create a Workspace as an ODBCDirect. After I execute the open_data_base using the workspace. Here you can specify the parameter connect with /type of connection / user / password.
The problem is the following:
Although you configure a password for the Administrator user in Access, you can read/writte to data base from Labview using ADO without any security and without putting the user and password in the parameter connect. I need to access with security to data base using users and permissions but it seems that the parameter connect does not operate.
I attach
you a example of the vis and database. Remember create a ODBC connect with BD3.mdb
Thanks a lot

Hi Kahn,
If you use ADODB_connection -> Connection.Open and set in connection string :
"Provider=Microsoft.Jet.OLEDB.4.0; Jet OLEDBystem Database=c:\.....\Protegida5.mdw; Password=pepe;user ID=jose; Data Source:c:\......\BD5.mdb";
and after connection.execute ->
INSERT INTO tabla1 VALUES (5,'XXX'
you will be able to access to the database with security using the provider=Microsoft.Jet.OLEDB.4.0. With this provider you have to use the path and the name of the database file c:\.....\mdb file. From this way the problem is solved. (SEE SAMPLE_ADO_W2_JET.VI).
BD5.mdb have the following administrator user: user:jose / passwordepe (Protegida5.mdw)
The problem is when you want to
use ODBC and DSN. The name of this ODBC Provider is MSDASQL;. If you use this type of connection you can not enter to the database I attach you.
This database has a new administrator owner. I deleted the default administrator. If you support the default administrator you can connect to database by ODBC / DSN but the security disappear because you can always enter to database with any password, user o PC.
FINALLY I HAVE 3 QUESTIONS FOR Application Engineers of National Instruments or someone who knows these subjects before deciding the best way to connect locally o remotely with security to Access from Labview:
1.- Is it possible to enter to Database BD5.mdb from ODBC and DSN with this owner?
2.- I want to connect remotely to Access database too. Is it possible to use Microsoft.Jet.OLEDB.4.0 using the path (.mdb file) without DSN?
3. Which is the optimal Provider for Microsoft Access?
I thank you beforehand for your technical support.
Peter Mst.

ORA-00900 when there is huge quantity access to Data Base

Hi
I have some Java programs which access to the same Data Base Oracle 11gR2 from diferent computers and diferent Operative System.
in a normal execution everything is working but when I want to test the 'stress' in the data base I execute many concurrent programs. The problem is that when I execute too many programs the data base answer me 'java.sql.SQLException: ORA-00900: sentencia SQL no valida' (I´m sorry the spanish expresion, I don´t know the english correspondence)
The SQL sentences are static.
Do you know why? and do you know the solution?
Thanks you for your answers
Pablo José Izquierdo

hi, thank for your answer
I enable a logging in my Java program and after the execution I write the sql sentence which causes the exception in my SQLplus and it´s correct. The programs execute the same 4 sentences about 50 time every second (more 200 access every second and every program) and it´s only return a problem when I have too many programs.
It´s only happens sometimes, no always, but the execution is very long and I find the problem at some point in the same
The database is Autocommit and the sentences are on the same table but on diferente values.

Suggestion to have a Test Data Base

We have a "Production" Data Base Oracle 9i Release 9.0.1. 4.0 and we want to set up a "Test" Data Base because we need to make many changes and we don't want to affect "Production Data".
We are thinking on using "Oracle Express" since we do not need a lot of data to do the test.
Is this a Good Solution?
Also we want to set up a process to transfer Data from Production database to this Test database.
Any suggestions on how to accomplish this?
Thanks a lot for your comments...!!!!

We are thinking on using "Oracle Express" since we do not need a lot of data to do the test.
Is this a Good Solution? Nope. You need to have a test environment (you haven't had one all this time?) that mirrors your production environment as closely as possible.
Having exact duplicate hardware can be difficult (i.e. expensive), but your Oracle installation should be exactly what you have in production.
The best way is to use one of the many methods of cloning your production environment to your test environment.

How to access two oracle data base with out DB link

The target database can implement PL/SQL web services. These can be called via HTTP.
The local database can use UTL_HTTP to make a call to the target database's web service for accessing target database data.
Both databases can use AQ (Advance Queues). This can be integrated with an application server's JMS queues.
This enable one database to enqueue a request to the other database, and for that database to respond by sending data.
There are numerous such type of interfaces that can be used. Some primitive. Some advanced. Some simple. Some complex.
The easiest and most flexible mechanism is however a database link. And it does not make sense to disallow database links for security and management reasons, but allow JMS for example. The network infrastructure is the same for both methods. The network protocol is the same. The security issues and concerns are the same - except that JMS for example is significantly more moving parts and make configuration and security a lot more complex than using a database link.

How do you import data base dmp file in oracle 10g

How do you run data base dmp file in oracle 10g

Examples..
Table Exports/Imports
The TABLES parameter is used to specify the tables that are to be exported. The following is an example of the table export and import syntax:
expdp scott/tiger@db10g tables=EMP,DEPT directory=TEST_DIR dumpfile=EMP_DEPT.dmp logfile=expdpEMP_DEPT.log
impdp scott/tiger@db10g tables=EMP,DEPT directory=TEST_DIR dumpfile=EMP_DEPT.dmp logfile=impdpEMP_DEPT.log
For example output files see expdpEMP_DEPT.log and impdpEMP_DEPT.log.
The TABLE_EXISTS_ACTION=APPEND parameter allows data to be imported into existing tables.
Schema Exports/Imports
The OWNER parameter of exp has been replaced by the SCHEMAS parameter which is used to specify the schemas to be exported. The following is an example of the schema export and import syntax:
expdp scott/tiger@db10g schemas=SCOTT directory=TEST_DIR dumpfile=SCOTT.dmp logfile=expdpSCOTT.log
impdp scott/tiger@db10g schemas=SCOTT directory=TEST_DIR dumpfile=SCOTT.dmp logfile=impdpSCOTT.log
For example output files see expdpSCOTT.log and impdpSCOTT.log.
Database Exports/Imports
The FULL parameter indicates that a complete database export is required. The following is an example of the full database export and import syntax:
expdp system/password@db10g full=Y directory=TEST_DIR dumpfile=DB10G.dmp logfile=expdpDB10G.log
impdp system/password@db10g full=Y directory=TEST_DIR dumpfile=DB10G.dmp logfile=impdpDB10G.log

How we create new data base in oracle 10g express edition

hello every body.. i student of B tech n new user of oracle so please help me how we creat new data base in oracle 10g express edition

Hello, Oracle XE can not create more than one instance, the other editions yes, but like other editions XE allows you to create database schemas, schemas logically grouped objects like tables, views, indexes created by a user. By creating an Oracle user is associated with a schema of the same name.
Using SYS or system accounts for creating user accounts.
Syntax to create a user:
create user Your_user
IDENTIFIED BY password
default tablespace users;
grant connect, resources to your_user;

Migrate existing data base to oracle 10g and cluster it

hi
we are currently using sql server 2000 and due to some servere dead locks in the application and due to some load issues we wanted to migrate it to oracle 10g.
At the same time we wanted to have clustered environment in the same server
That is windows server.
Can any one suggest how migration can be done..easily ie..by oracle migration work bench or what...
At the same time can any one suggest how to cluster data base in windows server
Thanks

This is re-engineering from one database platform to another.
You will have to take into consideration several aspects of your application, from SQL comptability to the application performance (SQL) in the Oracle environment.
There is no magic to this puzzle, the amount of task involved in moving from one database to another depends on complixity of the application and how many database operations will have to be changed. I would suggest /recommend that you should start with a POC on a specific module /area (probably the most complex) of your application and this should give you some idea in the efforts of doing so.
