Oracle ODBC Connectivity with db2

I want to connect forms/reports with
IBM DB2 Database installed on the
same machine.But while connecting
through odbc driver it gives "Invalid
session id,access denied"and does not
get connected.Same message comes when
one gets connected to sql but it runs fine.
I have tried in two ways to configure ODBC.
1. Using Client Configuration Assistant
of DB2.
2. Usgin OCA and Intersolv odbc
driver coming along with the cd.
Forms and reports are 6i and
db2 version is 5.
Thanks in advance.

Dear Ajay,
I used heterogenous connectivity to connect to DB2 but it is very very slow. And checked about Oracle gateway to Db2 and came to know that it is also very slow. The next solution was using ODBC to db2 using Forms 6i Patch 13. The connectivity is very good otherwise u can use DB2 Information Integrator software (cost about $20-50 K). If you need any more information please let me know.

Howmany oracle user connect with oracle server.

hi all
howmany oracle user connect with oracle server.
i want query for above sentance.

Robert,
This query will show us the username who are connect to a particular database. If OP wants that how many overall users are connected to his/her oracle server (which is having more than one db) then please tell us. Suppose 10 users are connected with db1 and 20 users are connected with db2.. like that.

Oracle heterogeneous connectivity for DB2

Hi,
We want to connect DB2 database with Oracle 8i. We have read that it is possible with Generic connectivity and Transparent gateways.
Any one knows the differece between the two when connecting to DB2?
Which one is simpler if we have to use dblink concept
Thanks,
Ajay

Odbc-connection with ms-access

hello,
this is my problem
if I migrate an MS Access db to Oracle with the OMW than is the ODBC connection, from MS Access to Oracle, perfect.
Bud I have used the migration script witch is generated by OMW and by made a connection from MS Access to Oracle in some tables the ODBC connection Failed.
What is the problem????
Thanks

You don't need MS Access installed to use the JDBC-ODBC driver.

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 Connectivity with Crystal Reports 2009 and MySQL

Hi,
I'm hoping someone can help me. We are currently running Crystal Reports CR Developer version 9.2.2.693 with an ODBC connection (ODBC 3.51 driver) to a My SQL database, version 4.0.18.*
We want to upgrade to Crystal Reports 2008, CR Developer version 12.0.0.683, however when I try to run reports to the current database, I get the following error:
*Database Connector Error: 2300:[MySQL][ODBC 3.51 Driver][mysqld-4.0.18-nt]You have an error in your SQL syntax. Check the manual that corresponds to your MySQL server version for the right syntax to use near .client where 0=1 at line 1 [Database Vendor Code: 1064] *
Has anyone encoutered this before? Do I need to get a different rev. ODBC driver? Thanks in advance for your help.

Thanks for your suggestion, but since the same query works when I use Crytal Reports 9 to the same MySQL database, I don't think that's the issue. I wonder if it has to do with the driver.

Need help making odbc connection to db2

I'm tying to connect to an ODBC connection and am getting an error, while running on NT V4, and Oracle v8.0.3.
I cannot connect by issuing the following from the Command line
PLUS80W.EXE user/passwd@odbc:db2_dev
I get the following error message:
ORA-12154: TNS:could not resolve service name
Yet I can connect using Oracle's "Oracle ODBC Test", selecting the proper 'machine data source' and typing in the username and password.
Any ideas on how to proceed?
Do I need to add a service name to the tnsnames.ora file, if so, can someone provide a sample for an ODBC source?
Thanks

SQL*Plus is an Oracle tool. At one point, I believe there was a facility that let you connect SQL*Plus to other data sources via ODBC (the acronym for this was OCA, Open Client Adaptor, I believe). As I understand it, though, this has been desupported.
There may be some folks in the SQL*Plus group that know the proper incantation to get this to work.

Odbc connectivity with Data services 4.2

Hi guys
i have very general question to ask...
presently i have dataflow which has one source table connects to query transform and further query transform connects with target table.. query transform has no filter, no order, no group by ... it is simple select * from source table ......... company where the source tables resides have given us their odbc driver to connect and extract same data... but it takes very long time to copy at our end.. i admit that data is more than 100 million (takes more than 4 hrs) records.. but could you please help me to debug what can be done to increase the performance and how can i check why it takes very long time...
ODBC connection set up in administrative tools->ODBC application.. is there any other way to set up the odbc....
when i run same query on the tool provided by them to connect with LIVE system.. it takes half of the time taken by data services to copy..
I have tried changing the dataflow properties between in-memory/ pageable with degree of parallelism.
what can i check on my end if anything wrong going at my end... before i tell anything to source company to see...
I would be very greatful if anyone can help me to understand same.
regards

Hi,
If your database is SQL server, install a SQL native client on the DS machine to connect to the DB. You don't need a ODBC for connection of DS with DB.
Check this, assuming your DB is SQL.

ODBC Connection with one to many results

Hi there - I have followed Stefan Cameron's excellent blogs on linking livecycle forms to data from an odbc connection however I have now become stuck.
Effectively I have a form that populates part of the form with matching data for a specific id, however I then need to populate a different part of the form from another database connection that holds multiple records for that id.
I have successfully completed the first part (YEAY!) however the second bit I cannot do - I have tried using the xfa.sourceSet.dataconnection.next() however this repeats the same data and doesn't seem to want to get the next record.
What I seem to need is a mix of Stefan's "selecting specific records" (which works great for the first bit) then the retrieving ALL records bit from here
http://forms.stefcameron.com/2006/10/12/displaying-all-records-from-an-odbc-data-connectio n/
but only where the relation matches the first section.
Does anyone have any ideas - I'm sorry if I am not being very clear - I can post more detail if needed.
Regards,
Bev.

Thanks Paul - I already have two data connections as there are two different result sets I am working on
To clairfy - the first data connection retrieves grant id, title name and address of all grants
The second data connection then retrieves financial data for all projects related to those grants
There are several records of financial data per grant.
So the first bit of code retireves all relevant data for the grant selected.
xfa.sourceSet.claimdata.#command.query.select = concat("SELECT grt_title, grt_contact, grt_org, grt_addr, grt_post FROM gs_user_claim_pdf_table WHERE grt_id = ",sGrtId, ";")
xfa.sourceSet.claimdata.open()
xfa.sourceSet.claimdata.first()
This bit works fine
The second bit is only working for the first record it finds - what I need to do is to loop through all the results and populate a repeating subform with the relevant results but I just don't know how!
xfa.sourceSet.subproject.#command.query.commandType = "text"
xfa.sourceSet.subproject.#command.query.select = concat("SELECT sub_prj_title,claim_amt,tot_est_cost,unit_type,total_units,funded_by,exp_type,grt_id,prj_ id FROM gs_user_sub_proj_table WHERE grt_id = ", sGrtId, ";")
xfa.sourceSet.subproject.open()
xfa.sourceSet.subproject.first()
_subprojects.addInstance(1)
xfa.sourceSet.subproject.next()
Any pointers gratefully received!

Oracle ODBC Connection: TNS Problem?

Hello!
I'm trying to connect to a Oracle Database from a 64bit Linux machine.
I'm using instantclient 10.2.0.4 64bit and oracle odbc driver.
Here are all files and env variables, i created:
ODBCINST.INI
[Oracle]
Description = Oracle Driver
Driver = /usr/lib/libsqora.so.10.1
UsageCount = 2
ODBC.INI
[DS1]
Description = DS1
Driver = Oracle
Trace = Yes
TraceFile = sql.log
Database = //111.11.11.111:1111/db1
User = user
Password = pass
LD_LIBRARY_PATH = :/usr/lib/oracle/10.2.0.4/client64/lib
SQLPATH = /usr/lib/oracle/10.2.0.4/client64/bin
I also had edited the SQLConnect.c and isql.c: http://sourceforge.net/tracker/?func=detail&aid=2260937&group_id=1544&atid=351544
If i'm tring to connect to the database ( isql -v DS1 user pass ), i'm getting this error message:
[S1000][unixODBC][Oracle][ODBC][Ora]ORA-12162: TNS:net service name is incorrectly specified
I found a nice work-around for this problem:
export TWO_TASK=//111.11.11.111:1111/db1
After this change, i can connect to the database...
But this means, all oracle connections are trying to connect to THIS server, right? But i need more then one server possibility...
Any ideas?
Thanks, mdo.

Hello
I have found the resolution to the problem , and below is the details if required by any one .
Thanks

1. Using MS Access, follow the process to link tables from the Oracle
database using the user account you wish to restrict, until the list of
attachable objects is shown.
2. Note the tables that appear in the list. You should see a long list of
tables owned by multiple schema owners.
3. Without linking any tables, close the Link Tables dialog box.
4. Create an ALL_OBJECTS view and ALL_SYNONYMS view in the user's schema in
which you used to log into the database.
For example:
CREATE OR REPLACE VIEW SCOTT.ALL_OBJECTS AS
SELECT * FROM SYS.ALL_OBJECTS
WHERE OWNER IN ('SCOTT');
CREATE OR REPLACE VIEW SCOTT.ALL_SYNONYMS AS
SELECT * FROM SYS.ALL_SYNONYMS
WHERE OWNER IN ('SCOTT');
5. Using MS Access, again follow the process to link tables from the Oracle
database using the user account from above to log in.
6. Note the tables that show up in the list. The only tables listed should
be those owned by the schema owner specified by the views, if the example
statement above is used.
--NOTE that this technique has the limitation that only objects actually
owned by the view user will be viewable. For example, if the user has
a synonym that points to an object in another user's schema, it will not
be visible

Memory leak using Oracle ODBC connection. Works perfect with MSSQL.

Hello,
what could cause memory leaks which is not persistent. Sometimes in different OS and sometimes in different hardware. the common player to my issue is only with oracle.

A memory leak that is not persistent is not a memory leak.
You'll have to be way more specific for a more meaningful answer.
Have you tried memory profiling tools for your operating system to locate the "leak"?
Yours,
