You're free to come to that conclusion, but you would be
totally wrong.

The error message "[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified {IM002}" is self explainind - DG4ODBC is not able to find the ODBC DSN you created.
In your gateway init file you configured the DSN: HS_FDS_CONNECT_INFO = testmysql
And according to the Windows ODBC Admin screenshot you created a DSN called testmysql - unfortunately you created it as a USER DSN. But DG4ODBC needs a SYSTEM DSN. The reasin why it needs a system DSN is that by default the Oracle listener is running in the local system account. So when you create an ODBC USER DSN it can be access by the user who created it, but nobody else can use it - also not the local system account which is serving the Oracle listener. So you need to create a system DSN that every user on this machine can use the DSN (including the local system account) .

The errors are cannot import this tables..
Also mostly are of Long tables..Any IMP-XXXXX or ORA-XXXXX messages?
Can you explain how long objects are exported and imported ?What type of objects?
What is the database version?
Are you doing a full database import?
Also sometimes import hangs for 2/3 days?Does it hang when importing a specific object?
Did you follow the steps outlined in the following notes when you did the Export/Import?

Differences in the characterset used by the database & Oracle Applications

Hi All,
I have encrypted one column in the database using Oracle DBMS_OBFUSCATION tool package.When the same field is viewed from the application the characters appear different from those that are there in the database and also sometimes the value is truncated from the applications.
Could anyone please help me understand why it is happening.
Is there any difference in the characterset used by the database & Oracle Applications ??
Please help me ASAP.
Thanks in Advance,
Aush

What I mean by the characters displayed on the form in the Oracle Applications is different from the database value is that suppose the value in the database is 8¿x¿"h the characters(part of the string) displayed in the form are different from what is present in the database.

Unable to connect to Oracle Applications database (afscpgcs) after clone

Hi,
I have just moved (clone using rapidclone) two of our 11.5.10.2 install from a solaris SPARC 8 to 10 . After the clone, while discoverer 10g works perfectly well in one environment, it is giving the error below in the another environment.
- Failed to connect to database - Unable to connect to Oracle Applications database (afscpgcs)
Notes:
1. For the 2 environments, nothing as changed apart from the hostnames.
2. The password has not changed on both - from source to targets.
3. This happens when launching discoverer 10g from Apps.... discoverer works well on it own if not launched from apps.
I raised a SR with oracle and the 2 things they said have not worked. they said
1. change signon password case parameter - but I cannot find that in the list of system parameters on our system.
2. The other note says apply patch 6430269 and I can confirm this patch has been on the system for sometime.
Please advise on this if you have come accross this before and you can help here.
Thanks

Thanks for your concern. I have used the notes you listed but no luck. One thing I have to point out here is that I have always cloned from solaris 8 to 8 for years without this problem. Now I am cloning from solaris 8 to 10 and the problems is on just one environment. The other is working well. The problem seems to be related to the apps password but the password has not changed at all. Also, I have tried to change the password to something else and ran autoconfig but no luck. Please help

Unable to connect to Oracle Applications database invalid username/password

Hi,
Ou Requirement is we want to connect to Oracle Applications using discoverer plus and discoverer viewer.
Application Server used : 10.1.2.0.2
Oracle Applications : R12 RUP4
We have installed application server 10g with OID and when we try to connect to oracle applications we are getting
A connection error has occurred.
- Failed to connect to database - Unable to connect to Oracle Applications database: invalid username/password.
Regards
Ketan

Hi,
I think better to check with your sysadmin or DBA on this, I had the same isuse before but Apps 11i with Discoverer, I talked to ERP sysadmin and worked fine.
Since applications userid cannot talk with Discoverer schema (eul10_us) and it should directly talk with APPS user and then APPS user can talk with Discoverer user.
To the best of my knowledge I provided.

Common Supplier master database for Custom Applications and Oracle Financia

Hi,
We would like to build a custom applications (Multiple) for our organization core business operations using .NET on the database which is being used by Oracle financials R12.1.1. These custom applications are going to have its own application servers. BUT the database is common for both custom applications and oracle financials. This database is going to house on the Oracle RAC.
We would like to have a common supplier master for both custom applications and Oracle payables. Could you please help me with below questions?
1. How to create/Update/Query the supplier records in the supplier master tables provided by Oracle financials using custom applications?
2. How can we store the additional data elements needed by each custom application? We can't use the DFF on the supplier tables as the data elements for each custom application is going to be different. even though they use same supplier.
3. We might have multiple supplier with same name but different FEIN/SSN numbers. As per the design Oracle financials doesn't allow the same supplier name entered multiple times even though FEIN/SSN number is different. How can we workaround this limitation?
Thanks,

Hi,
Please find my comments below:
1. How to create/Update/Query the supplier records in the supplier master tables provided by Oracle financials using custom applications?
A: You may use Supplier Open interface and Sites Interface to Create the Supplier Records. I don't think there is any API to update Supplier Info. Since both the applications exist on same database, I think you can query the Vendor tables from Custom applications also.
2. How can we store the additional data elements needed by each custom application? We can't use the DFF on the supplier tables as the data elements for each custom application is going to be different. even though they use same supplier.
A. Designing different tables depending on Custom Application ID and Vendor ID seems to be the only option.
3. We might have multiple supplier with same name but different FEIN/SSN numbers. As per the design Oracle financials doesn't allow the same supplier name entered multiple times even though FEIN/SSN number is different. How can we workaround this limitation?
A.One alternative is to create a single supplier with each FEIN/SSN number as site. Second one is to create Supplier Name concatenated with FEIN/SSN numbers as different suppliers and store the actual name in some DFF or other field. Standard functionality won't allow such duplication (Cannot Create Supplier/Employee With The Same Name Of Existing Supplier [ID 743430.1]).
Hope it helps.

Sridhar

Tnsping timed out using dg4odbc from Oracle to MYSQL through ODBC

Hi,
I encountered problem when trying to connect from Oracle to MYSQL using dg4odbc, hope you can shed some light
Oracle database is 11.1.0.7 on SUSE Linux 64-bit.
Since the application which runs on MYSQL DB only offers ODBC driver on Windows platform, so I installed the 32-bit ODBC driver (from ServiceNow) on a 32-bit windows server (driver download from http://wiki.service-now.com/index.php?title=ODBC_Driver) .
created system DSN: MYSQLDEV, The DSN connection works fine. I then installed Oracle 11.2.0.1 gateway for ODBC 32-bit on the same windows server, the following configurations were done:

if listener is not listening to the service, then the tnsping on the windows server should fail as well.
I don't know why only the tnsping from Linux failed, is it due to the 32-bit ODBC uncompatibility with 64-bit oracle server? or my configuration problem?
Of course, when I created the DB link from oracle, the connection failed with
create database link mysqldev connect to xxxx identified by "xxxxx" using 'jelly';
Database link created.

Database Link to Mysql Database.

Hi Guys.
I need to Create a Database Link a Mysql database that is running over a Red Hat server to my Oracle 10g Database that is running over SUSE. I Have an Application server where the user runs forms and Report. The user access the Application Server that allow them to connect to Oracle Database because is a web Environtment. I would like to access MYSQL database to pull our some data to create a couple of Views for my Users.
Thanks in Advance.
Emmanuel
PD: do I need to configure some ODBC or just modify my tnsname.ora file???

add a space to each line in the SID section of your listener - only GTW_LISTENER and SID_LIST_GTW_LISTENER are valid commands to start at the first position in the file.
In addition please remove that line from your gateway init file: HS_FDS_SHAREABLE_NAME=C:\Program Files\MySQL\Connector ODBC 5.2\myodbc5w.dll
HS_FDS_SHAREABLE_NAME is used on Unix to specify the ODBC Driver Manager - as you're on Windows where Windoes ships a valid ODBC Driver Manager you don't need to specify that parameter.manager. In addition please remove the set ODBCINI parameter as the Windows ODBC Driver Manager uses the registry. So make sure you have created a 64bit ODBC system DSN using the 64bit MySQL ODBC driver (it has to be the 64bit ODBC driver as you're on a 64bit Windows using a 64bit DG4ODBC)
