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.
I 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.
When 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.
I'm trying to add edmx file in my project for first time. I want to choose the oracle provider ODP.net but cannot find Oracle in the data source list. I have oracle 11g installed , odp and odt installed and can access it from the solution as well. I saw the Oracle listed under data source when I tried to connect the solution to the database through server explorer. The solution is connected to Oracle database through ODP.
I have built a Menu Framework using the following instructions.

I am facing 2 problems.
1. If the user is in a child application and clicks logout. He is taken to the login screen of the master application (Correct), but once he enters login details, he is returned to the child application (False). I think he should be returned to the Home page of the Master application.
2. If I set Session Timeouts in the Edit Security Attributes of the applications. Then if the user is timed out, he is sent to the login screen of the Master application (Correct). If he then logs in, he is sent the the Home page of the Master application (Correct).
Now if he clicks a link to a child application he is then sent back to the Master application login screen. He then has to login again. He is sent to the Master Home page and everything is then ok.
How to configure Oracle EM with newly created Oracle Instance on Oracle 10g DB,which is Single Instance DB but not RAC ,when I start the Oracle EM it is starting the default DB which created during Oracle Server Installation.
But i do a lot of work-arounds to make sure the installation does not make corrupt my OracleAgent,OracleService and OracleDataGatherer. If i just let the installation do its thing i have problems with my libraries, and can't start anything.
The errors are : Procedure entry point 'BlaBla' could not be located in the Dynamic Link library 'AnyName'.
I notice that i have 2 versions of the libraries in OracleHomeBIN (one version 8, one version 11). The programs that start the OracleAgent,Service and DataGatherer call the old libraries but expect to find values that can be found only in new libraries.
I have a requirement to put together a Oracle SQL template to create re-usable DDL/DML Scripts for Oracle databases.Only the Oracle DBA will be running the scripts so permissions is not an issue.
The workflow for any DDL is as follows:-
1) New Table
a. Check if the table exists from the system/admin views.
b. If table exists then give message "Table Exists"
c. If table does not exist then execute DDL code
2) Add Column
a. Check if Column exists for a given table from system/admin views
b. If column exists in the specified table,
b1. backup table.
b2. alter table to make changes to the column
b3. verify data or execute dml script convert from backup to the new change.
c. If Column does not exist
c1. backup table
c2. alter table to add column
c3. execute dml to populate column with default value.
The DML scripts are for populating base tables with data required for business operations.
3) Add new row
a. check if row exists by comparing old values of each column with new values to be added for the new record.
b. If exists, give message row exists
c. If not exists, add new record.
4) Update existing record (We have createtime columns in these tables so changes can be tracked)
a. check if row exists using primary key.
b. If exists,
b1. deactivate the record using the "active" column of the table
b2. Add new record with the changes required.
c. If does not exist, add new record with the changes required.
We would be moving oracle 11g unix sun solaries to oracle 11g Linux readhat OS. what would be the disadvantage and what are the item needs to be verified. Basically advantage of oracle 11g Linux readhat OS.
I would like to update an XML element without using the function APPENDCHILDXML or INSERTCHILDXML because they are not available in Oracle 10GR1. In my database, Oracle XDB is not installed.
The following query fail with the following error : ORA-00904: "INSERTCHILDXML" : identificateur non valide
update scl_profile set profile_data = insertChildXML(profile_data,'/exportImportMarcheCriteria','colonnesExport', XMLType('<colonnesExport>ENTETE_GESTIONNAIRES_AUTORISES</colonnesExport>')) where profile_xmltype = 'fr.mipih.marches.marche.criteres.ExportImportMarcheCriteria' and profile_type = 'eMagh2.MRGS.AccesMarche.ListeMarche.Export.OptionsExportImport'; [code]........
If i try to use the package DBMS_XMLDOM, i have the following error :
ORA-06550: Ligne 3, colonne 11 : PLS-00201: l'identificateur 'DBMS_XMLDOM.DOMDOCUMENT' doit etre declare ORA-06550: Ligne 3, colonne 11 : PL/SQL: Item ignored
I think it's because ORACLE XDB component is not installed in my database.
This time i am downloading the Oracle 11g and then the Oracle APEX...(they are not in one package...right ? i mean they both have to download separately)i really new in oracle / PL/SQL. I'm not a programmer but i interest about database programming.For now i still use Ms. Access to develop an aplication and i really suprised i found this Oracle APEX because it an RAD tool too same as Access but more powerfull i think.
I am working on an application which is on Oracle forms and Reports 6i.It connects to a database which is Oracle 9i. My client wants to upgrade the Database to Oracle 10gR2 or Oracle 11g. I searched in many forums and also saw in Interoperability table which says it is not compatible. But some users are using it fine.
Can I directly upgrade Oracle 9.2.0.1.0 From RHEL-4 platform to Oracle 11g Rel 2 on RHEL -5 platform?I have the export dump and cold backup of Oracle 9.2.0.1.0 database.
I am getting "ORA-03114: not connected to ORACLE" while installing "Oracle Database 11GR2" on "Oracle RAC 11R2" cluster setup. I am getting this error at the time of "Oracle Database Configuration Assistant" configuration reaches till 39% on HP-UX 11.31 IA64 platform.
I want to manage database (create table ,insert data ,delete table etc ) by using tool in oracle 10 g similar to a OEM in oracle 9 i in order to manage the database simply and not using SQL command
I used to open OEM in browser but I don't know to manage my database method by using OEM . In a screen I find many function for example Host CPU Active session etc but I can't find function are about create database create table etc . And this is my question
How I did open OEM in order to manage database (create table ,insert data ,delete table etc )?
While installing oracle 9i on windows XP. Oracle database configuration agent fails.
And it throws following error message.

this is just a generic question. If a table has multiple Indexes on it say a table of 20 columns where 8 columns have indexes on it (each columns out of the 8 has an index on it and out of which three columns contain unique indexes on it).
If i run a query on this table where only two columns are specified in the where clause are the remaining 6 indexes on the table scanned during query execution.
I am facing problem with a select query in oracle 10g database from vb.net.It was working for oracle 9. The select statement I have written is as follows
I am trying to upgrade database from 9.2.0.7 to 10.2.0 in my test server. Here are the steps i am planning to do.
1. Export user data of production, Import in test db(ABC) using Destroy=Y Fromuser,touser parameter( this step just to refresh old test data) 2. Install 10g db, Use DBUA Utility of 10g to start upgrade>select 9i database which i want to upgrade 3. follow DBUA instruction ..create datafile paths, init.ora file, tnsnames,listener... same as the existing setup i have of 9i(so i can make replica of 9i in 10g)
question: I have another database(xyz) in test server its also in 9i, I don't want to upgrade that for now. so do i need to use one listener /tnasnames file of 10g and include setting of 9i in that 10g file ?
How to manage init,tnasnames,listener files setting in 2 db versions . Is there anything else i need to do to perform upgrade 9i-10g ? or its all ?
I will install just 10g database will import full export of 9i db. if i can do full import in 10g or should i just go for fromuser, tuser option to import? i believe for that i need to create datafiles, user,grant in new 10g db. I am not sure which option is best to perform 10g upgrade?
I've been told by management this weekend I will be required to perform a complete patch of our Oracle 11g database.
Problem is I really have never installed / patched Oracle. I'm able to access pretty much any database here and interact with it from a SQL stand point so since I'm the only person in my entire office who knows SQL, they decided I can become their full blow DBA.
Currently the database is running a unpatched version:
Connected to: Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production With the Partitioning, OLAP, Data Mining and Real Application Testing options
SQL>
Once I download the latest patch (11.2.0.2.0) files from Oracle & perform a complete backup using RMAN:
RMAN> backup full as compressed backupset database plus archivelog;
How exactly does one properly patch / update Oracle 11g to the latest version?
We plan to deploy oracle EBS R12. what are all the components needed to build this infrastructure. ex. Oracle 11g database, oracle 10g application server.
also which solution should be deployed to ensure the Enterprise single-Sign On (ESSO).
Our Application is on Oracle 10g and we are going to migrate to Oracle 11g.
1) As of now we are using ojdbc14.jar. So if we migrate can we use the same jar or is it mandatory with 11g to use either ojdbc5.jar or ojdbc6.jar. I guess these jar version depends on the version of jdk we are using. But we are using jdk1.5 and still we use ojdbc14.jar which is working fine. So is it like , Oracle 11g can support only jdk1.5 or jdk1.6 ?
2) Is there any effect on the coding part if we change ojdbc14.jar to ojdbc6.jar ?I have seen there are some extra classes used in ojdbc6.jar.
3) Also we are going to migrate the Oracle database from Solaris to AIX. Our application lies on Solaris.So is there any compatibility problem , if our application lies on Solaris and database on AIX ?
