Oracle7 ODBC Driver with an Oracle 8 database

Does anybody know if there are any issues with using an Oracle 7 ODBC driver to access information on an Oracle 8 database?

Assuming you have an Oracle 7.3.4 client with the Oracle 7 ODBC driver, you're probably fine connecting to any of the current database releases. Since Oracle7 was desupported a while ago, however, there's no guarantee that this will continue to be the case as time goes on. Additionally, you probably won't be able to get support if you run into problems with this configuration.

[Fwd: Creating an ODBC Driver with Forte]

Has anyone created an ODBC driver with Forte? The Microsoft ODBC
Software Development Kit (SDK) assumes that ODBC drivers will be
developed in C. I would like to write the driver in Forte TOOL. Even
though C++ code can be generated from TOOL code, I am not certain that
the generated C++ code will conform to the ODBC API, and be compatible
with other ODBC components, such as the ODBC Driver Manager, ODBC
Installer, and ODBC Test applications supplied by Microsoft with the
ODBC SDK. Any advice would be appreciated. (The purpose of my ODBC
driver is to enable data access by any ODBC client application, using
calls to Forte service objects to retrieve and process the data before
it is sent to the client application.)

The following is extracted from Oralce's Metalink: (sorry lost the link)
"This is an NLS related issue. The ODBC driver uses the values derived from the NLS_LANG setting from the Oracle Home where the driver is installed.
The application actually uses the number setting from the NT Regional Settings.
When these two settings differ, then the decimal character will be cut off. This behaviour is also described in Bug:694323.
Example:
You have set your NLS_LANG in the ORACLE_HOME of your ODBC driver to GERMAN_GERMANY.WE8ISO8859P1. This will result in a value for the NLS_NUMERIC_CHARACTERS of ",." (the first part of the NLS_NUMERIC_CHARACTERS being the decimal character and the second part being the group separator).
So the "." is used by the Application and the "," is used by the Oracle ODBC driver.
As a result numeric values in your Oracle Database with an integer and a decimal part will thus be displayed by the application without the decimal character, i.e. a value of 10,734 will be displayed as 10734 a value of 0,123 will be displayed as 123.
To fix this, you will either have to correct the character used for the Decimal Symbol of your NT Regional settings to match the value of your Oracle NLS_LANG setting or vice versa. To change the value for NLS_LANG, go to your registry and change the NLS_LANG parameter that is situated under HKEY_LOCAL_MACHINE/SOFTWARE/ORACLE/HOMEnnn/NLS_LANG where HOMEnnn is the home where your Oracle ODBC driver is installed."

ODBC Driver to connect to Ingres Database from OBIEE

{font:Verdana}Hi, I have a requirement to source data from an Ingres Database into OBIEE. I have checked and found that Openlink Software provides an ODBC Driver to connect to Ingres Database from windows OS. Has any one tried this or any alternate method to source data from Ingres DB to OBIEE?
Any pointers would be great.
Thanks,
Kiran{font}

Kiran,

Sorry for bad news, but my opinion is that whatever isn't in doc that it's not supported. Oracle engineers do thorough testing and the list of compatible DBs is created. Also, even if you manage to make it work - you're going to hit a roadblock with any support issues you might have. Also, you won't be able to take advantages of certain DB-related OBIEE features. So you are're potentially exposing yourself to too many risks if anything goes wrong at mid-development stage.
My advice would be building your DW around Oracle-supported DB.
Good luck

Does JDev/JHeadstart 11g work with an Oracle 8i database

Hi All:
We are trying to plan with respect to going to 11g in JDev & JHeadstart.
Could anyone tell me if JDev/Jheadstart 11g work with an Oracle 8i database. One of our Vendor's db's is still 8i.
Thanks very much.

Oracle 10g ODBC driver with Windows 7 32 bit connecting to Excel

Hi Everyone,
I'm having an issue connecting to our oracle 10g database (64 bit system) from a 32 bit windows 7 installation running excel 2010/2007 using odbc drivers. Our excel spreadsheets worked without issue in windows xp.
In windows 7 I have been able to install the odbc driver via the following method:
1. Download the oracle 'basic' client and oracle 'odbc' client from www.oracle.com and extract the contents:
instantclient-basic-win32-10.2.0.3-20061115
instantclient-odbc-win32-10.2.0.3-20061115
2. Create a folder 'oracle' and place the instantclient_10_2 folder inside.
3. Ensure all the basic and odbc files reside in this folder.
4. Create a 'network' folder within instantclient_10_2
5. Create an 'admin' folder within 'network'
6. Create sqlnet.ora and tnsnames.ora files within the 'admin' folder:
7. Run 'obdc_install' within the instantclient_10_2 folder
8. Download and run the oracle odbc driver exe file from www.oracle.com (ORA10203.exe)
9. Go to Control Panel -> Administrative Tools -> Data Sources and create a new System DN
This allows excel spreadsheets connecting ONLY to oracle to function.
Unfortunately some of our spreadsheets connect to both a MySQL database as well as oracle. Spreadsheets connecting only to MySQL also function correctly, however, as soon as the vb associated with a spreadsheet includes a mysql call followed by an oracle call the spreadsheets fail. In Excel 2007 excel crashes completely everytime. In Excel 2010 the mysql data is generated, then when the script hits to oracle odbc connection there is a long pause, the oracle ODBC driver connect pops up requesting a username/password (this didn't happen in xp), then the data source selection pops up, then the username/password connect screen pops up again, and finally it fails with a runtime error '1004' General ODBC error.
If you look at the VB script it's failing at the Refresh BackgroundQuery statement in the ODBC connection block:
With Worksheets("Oracle1").QueryTables.Add(Connection:= _
"ODBC;DSN=Oracle_ODBC;UID=user;PWD=password;SERVER=ORACLE_LINUX;", _
Destination:=Worksheets("Oracle1").Range("A1"))
.CommandText = strSql
.Name = "Oracle1_data"
.FieldNames = True
.RowNumbers = False
.FillAdjacentFormulas = False
.PreserveFormatting = True
.RefreshOnFileOpen = False
.BackgroundQuery = True
.RefreshStyle = xlOverwriteCells
.SavePassword = True
.SaveData = True
.AdjustColumnWidth = True
.RefreshPeriod = 0
.PreserveColumnInfo = True
.Refresh BackgroundQuery:=False
End With
Does anyone know how to get around this? It's very important!!
Also if you try to edit the oracle ODBC connections in Control Panels -> Administrative Tools -> Data Sources, ODBC crashes 95% of the time.
Advice greatly appreciated!!

Well, here's what I'd check anyway..
1) get Process Explorer from http://sysinternals.com
2) make a mysql connection, get a list of dll's loaded (include the location and version columns in the lower pane output)
3) close that, then make an ora odbc connection, get a list of dlls.
4) close that, then make a mysql connection followed by an ora odbc connection, get a list of dlls
5) compare the lists of loaded dlls. In particular, the difference between #3 and #4, is there a dll dependency that gets loaded by oracle's odbc that comes from a different location when you've opened a mysql connection first?
May or may not help, but might turn up a difference to help point you in a direction.

Oracle ODBC driver with Access Application

I get a problem when using MS-Access 2007 DAO recordset built on table hosted by an Oracle database 10g and connected thru ODBC
The table scheme is :
idPartenaire : number(11)
libelle : varchar2(250)
code : varchar2(5)
actif : number(1)
idCollege :numner(11)
idPartenaire is generated by a sequence read in a trigger fired before insert on th table.
The code I use in Access is :
The query associated with the form is :
"select * from table1"
and the event procedure connected to a button on the form is :
Private Sub Commande0_Click()
Dim rs As DAO.Recordset
Me.Recordset.AddNew
Me.Recordset!libelle = CStr(Rnd) ' some value
Me.Recordset!code = “”
Me.Recordset!actif = -1
Me.Recordset!idCollege = 1
Me.Recordset.Update
Me.Recordset.Bookmark = Me.Recordset.LastModified
Dim idtemp As Long
idtemp = Me.Recordset.idPartenaire
Me.Requery
Me.Recordset.FindFirst "idPartenaire = " & idtemp
Set rs = Nothing
End Sub
When I run this code, I get an error 3167 (current record is deleted) on the line :
idtemp = Me.Recordset.idPartenaire
If I change the ligne :
Me.Recordset!code = “”
By :
Me.Recordset!code = “xxxx”
or if I comment this line, the error does not appear and I get the right value in idtemp variable.
I tried also with the same table in a SQL Server database table. In this case it works fine in all cases.
So, I seems that the problem is due to the Oracle ODBC driver. I tried with different versions of Oracle ODBC drivers (v10.0.2.4, v11.1.6)
I search on Internet but I have not found any explanation or solution.
Does anybody experiment the same problem (and find a solution)?
Gilles Roussel.

The two lines you quote aren't errors, they're warnings and they're pretty standard fare. If there isn't anything else in the ODBC log, then the driver isn't returning any errors. I'm not sure why Access is failing, so let's look at the client configuration first.
- I assume you've successfully installed the 8.1.6 client on the machine with Access. Were there any errors during the install?
- You say you're using the 8.1.6 version of the Oracle ODBC driver-- can you look to see what the last digit of the version is? If possible, I'd start by downloading the most recent 8.1.6.x ODBC driver from OTN.
- Check which version of the MDAC you have installed (new versions & a version checker are available from Microsoft at <http://www.microsoft.com/data>.
- The ODBC driver you download above will list which versions of the MDAC it is expected to work with. Make sure your version is one of the listed versions.

ODBC driver with Oracle 10G on 64bit Windows OS.

I m facing a issue with my peoplesoft application which is installed on Windows 2003 64bit OS.
Setup Details
Oracle 10G Server on AIX 5.3.
peoplesoft CRM tools 8.48,Oracle 10G client in on Windows 2003(64bit) installed.
When i open ODBC administrator from CRM its open showing all the drivers registred to 64bit registry. Whereas when i see ODBC admin from Control panel of OS , its showing driver register from 32bit. My observation is that oracle ODBC driver is getting registerd with 32bit and application is calling DDBCadmin of 64 bit. Hence driver is not getting registered with 64bit registry.

Hi kamlesh,
Thanks for your help, still i am not clear about installation on both nodes. once you install CI on one node you are giving the path of shared disk and if we go for other node then also we need to give the shared disk path : so will it or any other? if it is then alrady one usr and aracle folder exists after node A installation. Do you mean to say copy usr and oracle folder? please explain in detail, will be higly appreciable.

ODBC Driver with Access problem

I have problems with fields of the number(9.3) datatype. in my linked access tables numbers like 1555.33 are shown as 155533.
I'm using the oracle odbc driver version 9.2.0.54 with a 9i (9.2.0.1.0) Database.
I've reading at an old post called "number(9.3) DataType in MS Access". Where I've found someone with the same problem as me. I've done everythink which is explained on that message, but it still doesn't work.
Is there anything else to do?
Thank you in advance!

ODBC Driver with VC++ Application

Problem description.
For example if we are reading the EMP table with the following SQL,
select * from emp order by empno;
Step 1: We are reading the EMPNO = 7369 (1st Record)
Column COMM value read will be NULL
Step 2: After that when we read EMPNO = 7499 (2nd record)
Column COMM value read will be 300
Step 3: After that when we read EMPNO = 7521 (3rd record)
Column COMM value read will be 500
Step 4: After that when we read EMPNO = 7566 (4th record)
Column COMM value read will be 500 even though there is no value for COMM in the table.
Please note that we will not be able to change the Application code for this problem resolution.
We request you to give us some solution ASAP.
Should you have doubts in the information sent by us, please do revert back for clarifications.

Dear Justin,
Thanks for the reply and the information.
I am trying from Oracle support.
But any way I will answer your Questions.
Qus 1. What version of the Oracle ODBC driver are you using?
Ans 1. I can use both Oracle driver and Microsoft Driver.
Versions: Oracle ODBC Driver: 8.01.07.00
Microsoft Driver for Oracle: 2.575.1022.00
Qus 2.Did you try applying the latest patch set?
Ans 2.I have tried but it did not work. i.e. Problem continued.

What should i do with an Oracle 11g Database, MySQL database and a dump file.

I just joining to a new work field, almost about a database and i know "NOTHING" about this field.
My company has a system that running by Oracle Database, the problem is that Oracle Database will cost a lot of money when my company expands.
So the quest is converting Oracle Database to MySQL database.
Of course i cant try to convert it in the main Database, so i create one Oracle 11g Database on my LocalHost, and it already actived in " Localhost:1158 " etc.
I have another Sever test that already set up MySQL database, and a dump file from the system.
So I want to ask these 2 questions :
1. How to create an new Oracle Database from that dump file ?
2. Is it alright if i use tool to convert Oracle Database into MySql, or i should do it manually ?
Thanks alot.

I predict that converting to MySQL will cost your company more as it expands. As you expand managing contention becomes more important - Oracle does this for you. I do not think MySQL does, so you'll have to write more code to deal with this, costing the company money. A big part of making application scalable and reliable is to use stored procedures, how good are MySQL's compared to PL/SQL's. What other features are there that MySQL has that will benefit your company that Oracle doesn't. What do you need to think about as your company expands that need to be taken care of in the database. I would have thought a migration from MySQL to Oracle would be more common to deal with expansion.
As you know "NOTHING" you need to think about what each database can give you for the next 10 years to cope with you businesses potential requirements, and extimate how much it will cost to implement these requirements, then make the decision

ODBC driver hangs for two table joining

Hi,
I was trying to access two tables with the following statements. I used Oracle 8 ODBC driver to access Oracle 9 database. Statement 1 and 2 are working fine but executing Statement 3 will hangs the program.
Statement1: SELECT (fields from two table) from (table1 and table 2) where table1.key=123
Statement2: SELECT (fields from two table) from (table1 and table 2) where table2.key=345
Statement3: SELECT (fields from two table) from (table1 and table 2) where table1.key=table2.key
In the tables 1 and 2 there was no match key, but it should return NULL or nothing.. instead it hangs...
Anyone encounter this problem before? Thanks a lot for replying me...
Keith

Hi,
I have updated driver to the latest 8.1.7.8.10 which is availiable at the oracle-> download... but the problem still exit... execute sql statment 3 still hangs... :(...
Thanks for your advice..

Not able to connect to database using Oracle ODBC Driver

Hi,
I have installed Oracle client on a system. there are 2 homes installed. When I check the ODBC administrator, I see that only one ODBC driver is present. There are Net 8 services configured in both the homes.
When I try to connect to a database with the services configured in the second home using the ODBC driver, I am getting an error that the TNS name could not be resolved.
How can I use the ODBC driver to connect to the databases using services defined in the second home?
The name of the ODBC driver is 'Oracle in <firsthomename>
Thanks & Regards

Hi,
Thanks for the help.
I tried this, but it doesn't work. I'm still getting the error.
Now I am not able to create a DSN when I set the ORACLE_PATH to the second home. It says 'the setup routines for the Oracle in ora1 ODBC Driver could not be loaded due to system error code 998.'
Any other solution?
Thanks in advance & Regards

Oracle 10g Express Edition Beta 3 ODBC Driver Always Crashes

I find that if you set up an ODBC Data Source for Oracle 10g Express Edition on Windows XP SP2 using the "Oracle in XE" driver, anything that tries to access it will crash, even the Windows ODBC Data Source Administratior if you click the "Test Connection" button.
Having clicked the button, you get a window coming up entitled "Oracle ODBC Driver" with a yellow exclamation mark in it, with no other text in the window except for an OK button.
If you press OK, then it crashes and goes through the "Please tell Microsoft about this problem" process....

Hi,
Thanks for your comment, but I can't get onto the XE forum.
I found http://www.oracle.com/technology/products/database/xe/forum.html which says:
Forum registration is possible only by downloading and installing Oracle Database XE. After installation, click on the "Registration" link from the Database homepage.
However I find that the "Database Homepage" does not exist.
Choosing the Oracle XE "Go To Database Home Page" takes my browser to http://127.0.0.1:8080/apex which is not available even though my oracle server is running and sqlplus can talk to it.
There's definitely nothing serving on tcp port 8080, as follows:
[dcampbel@clevo]~> telnet localhost 8080
Trying 127.0.0.1...
telnet: Unable to connect to remote host: Connection refused

Oracle ODBC Driver adds bind variable when browsing whole table in Access

Hi, we are looking for some reasons why we may see this behavior in the Oracle ODBC driver (10gR2 and 11g) when using Microsoft Access (2003 or 2007)...
1) Link a table from the Oracle database.
2) Double-click the newly linked table to "browse" it.
Oracle sends the following statement to the server:
{color:#0000ff}select * from linked_table where primary_key = :b1{color}
It then proceeds to read the entire table.
If I tell Microsoft Access that there is no primary key, the query gets sent as:
{color:#0000ff}select * from linked_table{color}
And the query comes back as soon as the first 100 or so rows are fetched which is quite quickly.
ADDITIONAL NOTES:
1) If the table has a primary key or unique constraint, Microsoft Access automatically assigns that as the primary key.
2) We can stop the behavior in #1 if we wrap a view around it which prevents Access from discovering that information and then it prompts for a primary key definition.
3) If we use the Microsoft ODBC driver, the bind variable is not added no matter what the primary key defintiion is.
We're stumped and are looking for solutions and/or workarounds without having to wrap all of our tables in views to hide the fact that there is a primary key.
Thanks,
Steve

Thanks for the response, Greg.
The specific question I am seeking an answer for (sorry it was not clear on my first message) is this:
Why does the Oracle driver add the bind variable to the query only when the primary key is defined?
The Microsoft ODBC driver does not add the bind variable with or without a primary key defined.
You asked how I traced this statement and what I am doing is launching the query in Access and then using TOAD to view the V$SESSION and V$SQL_TEXT_WITH_NEWLINES views. All I do is change the driver. This is just for a simple browse table (double-click on the table) which should send
select * from table
However, whenever I use the Oracle ODBC driver (with a primary key defined) it sends
select * from table where primary_key = :1
If I remove the primary key on the table definition, the Oracle driver sends
select * from table
What is it about the primary key that could cause that behavior?
I don't think it is the MDAC/Jet level because this is the conversion to the native SQL statement not the Jet version. I know the Oracle driver has to do that part because you have those workaround options like don't add the RULE hint, etc. That's not part of the Jet engine.
Hope that helps. I'm just baffled over this one and wish I knew where to go next.

ASP pages and Oracle ODBC Driver

I have a number of ASP pages that need to be updated to connect to Oracle using the ORACLE ODBC driver. Currently, these pages connect using the Microsoft ODBC driver for Oracle. I do not know of all the details yet as I havent seen the pages or network for which they reside on and I havent been supplied with details on version information. I would assume I am working with recent versions of all software.
What Im curious about is if anyone has done this sort of driver change before and if you have any suggestions on how I would go about doing this, or if there are things that I need to be aware of that arent evident at first glance.
Again, I am switching from the odbc driver provided by Microsoft to a version of the odbc driver provided by Oracle.
Thanks for any and all information.

I'll assume that there is some reason that necessitates switching drivers. If there's not going to be a benefit, I'd suggest not changing.
That said, changing drivers should be relatively painless. If your ASP makes database connections using DSN's, simply go to the ODBC Data Source Administrator, rename the old Microsoft DSN, and create a new DSN using the Oracle driver with the name your ASP is looking for. If your ASP specifies the ODBC driver in its connect string, you'll have to modify all the ASP connect strings to use the Oracle driver. If all goes well, your ASP will now be up & running using the Oracle driver.
As we all know, however, reality and theory are often at odds with each other. While your ASP should be connecting to the database correctly when you make these changes, please do some thorough testing to verify that everything works like you expect. The ODBC specification permits drivers to have a variety of behaviors in certain conditions. Applications written with one ODBC driver often end up relying on one of these behaviors, and may break when the ODBC driver changes.
