View 5 Replies View RelatedServer Administration :: Difference Between A User And Schema On Oracle?
Apr 26, 2010difference between a user and schema on Oracle.By difference, I do not mean what is a user and what is a schema.
I understand that if we create a user, the schema gets created by default for that user. Does that mean that we cannot create a user/schema alone.
What if I just want to create a user and grant him some read access on an existing schema or just want to create a schema.
ODP.NET :: Oracle XE 11g And Entity Framework 4.4
Dec 4, 2012I have Windows Server 2008 R2 32bit and Oracle 11g Release 2 Express Edition installed on my server machine.
I have Windows 7 Pro 64bit, Visual Studio 2010 SP1 32bit, .NET 4.0 and Oracle .NET Data Provider (ODTwithODAC1120320_32bit) installed on my development machine.
The data provider download mentioned Entity Framework support. Existing tutorials on how to use Oracle with the Entity Framework makes me believe that EF is indeed supported! But when I try to create a new ADO.NET Entity Model, the Oracle data provider nor data source isn't listed!

On the other hand, if I want to create a new database connection, via the Server Explorer view, there are no problems connection to Oracle's DB.

The reason I need Entity Framework support is because we're migrating from MSSQL to Oracle and are looking for the most painless route to do so.
OLE DB :: Oracle 8 With Entity Framework?
Dec 10, 2012 am starting a new project for a customer who is currently using Oracle 8x. My experience as a software developer has been using MS SQL Server and so most of our code uses Entity Framework 4 and 5 with ASP.Net 4.0 and 4.5. This is my first experience with Oracle.
After doing some research I found that it looks like their version of Oracle is EOL and no longer supported. Does using Oracle Data connection tool kits for Entity Framework and Oracle 8? The tutorial that Oracle has on there site requires Oracle 10.25 or later? I am wondering if I will need to drop my code back to inline sql or if I can still use Linq with EF.
ODP.NET :: Entity Framework Concurrency - UpdateException
Nov 28, 2012When running into what should be an OptimisticConcurrencyException in entity framework, i'm getting an update exception as follows:
"A null store-generated value was returned for a non-nullable member 'DateChanged' of type 'FDDT.Model.FeedArray'."
I'm using the DateChanged field as the concurrency tracking field. In entity framework DateChanged has the following properties:
StoreGeneratedPattern: Computed
Concurrency Mode: Fixed
I have a trigger set on this field as follows:
TRIGGER FEED_ARRAY_TRIG_DTCHG before update on FEED_ARRAY for each row
begin
:new.DATE_CHANGED := sysdate;
end;
I've tried setting this concurrency tracking field to "Identity" instead, however that causes another error when I run into a concurrency exception and refresh using the client wins option.

Security :: Schema Consolidation And User Schema Mapping Based On Service
Jul 24, 2011We have an application with many separate databases (one per customer). Given they share the same business requirements (service hours, change mgmt etc), we're interested in potentially consolidating the separate DBs (which are relatively small) into separate schemas within a fewer no of databases to reduce the overhead.
Our issue is that the application is hard-coded to use a specific administrator and application connection user name. Changing this is unfortunately not an option.
Given this limitation, is there any possibility to map a generic user into a customer-specific schema based on the database service that they connect to? Each customer connects to different database services but may use the same user name. We considered using private synonyms but this seems to acheive the opposite (i.e. many different users could connect and map to a single users schema). One thing to point out is that where there is a single user name, it is acceptable for a single password to be used across the different customer DBs as they will be a single admin/user.

How To Fire A Schema Trigger From Outside Schema
Sep 24, 2012A user is using an ad hoc tool similar to SQL Developer called PeopleSoft Application Designer.
He creates a connection to the db, then issues an alter session set current_schema = 'restricted_schema'. The connected user does not have direct privileges on the "restricted_schema" which they call SYSADM.
After changing the schema context in that manner he creates objects in SYSADM. A schema trigger is then fired and grants privileges on the new objects created in SYSADM. Doing the same in either SQL Plus or SQL Developer does not fire the schema trigger.
I think SQL Plus and SQL Dev are working as they should. Altering the session like that does not change your identity - just the schema context. But, when you examine v_$session, the connection with this other tool looks exactly the same as one from SQL Plus or SQL Dev when changing the schema context in the session.
Instead of trying to figure out what this other tool is doing, is there any way for that schema trigger to fire when using this process from one of our tools?

PL/SQL :: Difference Between Oracle DB 11.2.0.1.0 And 11.2.0.3.0?

But when I do the same thing in Oracle DB 11.2.0.3.0. I can't use this user login with any password. I tried welcome1, "welcome1 " but all failed.
Why there are this difference between 11.2.0.1.0 and 11.2.0.3.0, and since in 11.2.0.3.0 the create sql are success, what password is correct when login?
