Error While Querying DB Link from Oracle 10g to Postgres 8.2

Hi,
I have installed unixodbc 2.3.1, postgres odbc driver (psqlodbc-07.03) and dg4odbc 11.2
On querying : select sysdate from dual@dblink_postgresql, the following error occurs:
ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
[unixODBC][Driver Manager]Can't open lib '/oracle/psqlodbc/lib/libpsqlodbc.a' : file not found {01000}
ORA-02063: preceding 2 lines from DBLINK_POSTGRES
Similar error appears in the trace file as well.

$ isql -v postgresql postgres postgres@2012

Do I need to install postgres software also?
While installing postgres odbc driver in /oracle/psqlodbc only two folders were created viz. lib and share
In lib folder two files were created viz. psqlodbc.la and libpsqlodbc.a
And everybody on the net seems to refer psqlodbc.so in the "Driver = " parameter
Today, I extracted the libpsqlodbc.a by using ar -X 64 -xv libpsqlodbc.a again, still no file with .so has been created.

Thanks.This is an error from SQL Server being passed back to Oracle so you can see the problem.
What it is saying is that you are trying to insert (or update) data to a database view and that view contains a column that is either a constant (literal) value or is derived (a calculation, formula or string concatenation etc.).
As such, you can't insert or update data on that column because it has nowhere to go on the database table(s) that underly the view.

Error while creating datasource userdsn for oracle 10g Errorcode (998)

while creating datasource userdsn for oracle 10g i am getting error "The setup routines for the oracle in OraDb10g_home1 odbc driver could not be loaded due to system error code 998" please give reply soon

Thanks for your reply , Steve.
I noticed that there is a default datasouce on the EM with the following parameters:
<data-source
          class="com.evermind.sql.DriverManagerDataSource"
          name="OracleDS"
          location="jdbc/OracleCoreDS"

          inactivity-timeout="30"
     />
The location and xa-location attributes that I use for my "test" data source are the same as the default one. So, could this be the issue?
What should be the values for location and xa-location attributes from my "test" data source?
Any help will be greatly appreciated.

GetBlob Error During fetching of Images from Oracle 10g

Dear Sir,
By using getBlob Function ,i am getting following error:"Unsupportable action has performed".
I am using oracle 10g.I am using java code to retrieve image from Oracle 10g.
So plz help me by giving full code with explaination.
Thankyou.
Yours Obedient
Dipesh Kumar

I seriously doubt Oracle would write error messages with such atrocious English.
So it's almost certainly an error from either your own code or code you're calling in some library or part of the application you're not mentioning that noone here except you has knowledge of.
Ergo, we're not going to be able to help you unless you provide a lot more information.
And no, we're not going to write your code for you.

Reading BLOB from SQL Server 2005 using DB Link from Oracle 10g

Hi All,
I am trying to read a table's data from SQL Server 2005 using ODBC DB Link created in Oracle 10g (10.2.0.3/4) database. I am not using oracle gateway.
I am able read all data except for the BLOB data from SQL server 2005. It gives error given below when I try to execute query SELECT * from T_TRANSACTION_DATA@sdeslink inside a stored procedure:
ORA-22992: cannot use LOB locators selected from remote tables
Kindly help how to read BLOB from SQL server 2005 inside Oracle 10g.
Best Regards!
Irfan

Irfan,
If you can read the blob data using 10.2 HSODBC then there should be no problem using the 11g gateway.
I recommend you download the latest version which is 11.2.0.3 available from My oracle Support as -
Patch 10404530: 11.2.0.3.0 PATCH SET FOR ORACLE DATABASE SERVER
This is a full version and does not need a previous version to have bene installed. When installing it needs to be in a completlely separate ORACLE_HOME from the existing 11.2 install.
For the Ora-22992 problem have a look at this note in My Oracle Support -
Ora-22992 has a workaround in 10gR2 (Doc ID 436707.1)
Regards,
Mike

Urgent:db link from oracle 10g to sql server 2000

Hi
I have a db link 10g from oracle to sql server 2000. This was created a couple of years ago. This is working.
I have now created another db link from same oracle server to the same sql server but it is not working.
But I am getting ORA-28500 and IM002 error
.Please advise.
I am unable to understand what is wrong because I have followed the hs odbc set up on this db link in the same way as I had done 2 yrs ago.
Thanks
Shailaja

Just sorted the problem.
Basically I am using HSODBC to communicate from Oracle (on windows 2003 64 bit) to SQL Server.
To do this, I need to create a ODBC connection from Oracle to SQL Server.
HSODBC is a 32 bit application and hence we have to use the ODBC 32 bit driver when we create the ODBC connection.
When I created the ODBC connection from Oracle to SQL Server, I was using the ODBC 64 bit driver and hence the system was unable to find the data source name.
I have now created ODBC connection from Oracle to SQL Server using the ODBC 32 bit driver and everything works fine now.
No offence to anyone but as you all work using Oracle software , I was hoping a better response than some of the above responses. You can just say that you didnt understand the question or you dont know the reason why that happened.
I just listed how the problem was sorted so that any one in future having the same problem can benefit.

Error while calling web service from Forms 10g

Oracle 11g- Straing behaviour of query after importing from Oracle 10g

Hi,
I have a table in Oracle 10g as follows:
Create Table xyz (col1 varchar2(50), col2 varchar2(50));
With following Data
Col1     Col2
A     320
A     110
A     290
A     380
B     ABC
B     256
B     LMN
I am running following Query
select * from xyz
Where Col1='A' and Col2=110
It works fine. But when I export this table and import it in Oracle 11g. It says invlid identifier.
But if I enclose 110 in single quotes. It works fine.
Also If I recreate this table in Oracle 11g like
Create table xyz1
as select * from xyz;
Now alos I am able to run this query smoothly.
select * from xyz1
Where Col1='A' and Col2=110
What is wrong exporting this table from 10g to 11g.
Any comments/suggestion??
Aarbi

The check in your where clause
Col2=110Is comparing a string (Col2 is defined as a VARCHAR) with a numeric literal, so there will be an implicit conversion taking place from character to number. The query then fails due to the B LMN row when 'LMN' fails number conversion.
I'm guessing there was there an index on the table in your 10g installation which would allow the query to be satisfied without checking the B ABC or B LMN rows but is not present or not used in the 11g installation so a full table scan results in an attempt to convert 'ABC' and 'LMN' to a number. Check the explain plans.
Or it could even just be a difference in the order in which the two conditions in the where clause are evaulated between the two versions.
The solution, as you have already found is to do a string comparision

Hi Sekhar,
Make sure that you are setting the environment first by running Midtier_Home\ip\install\setenv.bat OR Midtier_Home\ip\install\setenv.sh (according to your OS). Run the resubmit command after executing this setenv file.

Error while calling BI Publisher from Forms 10g using Webservice - Urgent !

Hi,
I am calling a BI Publisher(10.1.3.4.1) webservice from the Forms 10g (10.1.2.0.2). I developed a jar file which works fine when I run from the Jdeveloper. I have successfully attached jar file to the Forms 10g but when I am calling from the when-button-pressed trigger I am getting beow error
Exception: java.lang.Exception: java.lang.NoSuchMethodError: oracle.j2ee.ws.saaj.client.p2p.HttpSOAPConnection.setPreemptiveBasicAuth(Z)V
Thanks in advance

What steps did you follow to successfully attached jar file to the Forms 10g? To me, it sounds like you don't have your .jar file configured with Forms Builder and/or your App Server. Your .jar file needs to be added to the FORMS_CLASS_PATH in the default.env and the FORMS_CLASS_PATH registry entry. You will likely need to modify the formsweb.cfg also to include your .jar in the archive= or archive_jini= variables (depending on your JRE [Jinitiator or Sun JRE respectively]).
It could also be a dependency on an additional Java library. Is "setPreemptiveBasicAuth" a method that you created or it is a dependent method from an additional library?
Let us know this; as well as which Java version you're using.
By the way, with respects to your "Urgent!" request. You have to understand that forum contributers are purely voluntary - this is not our full-time job. If your issue is truely urgent, it is always best to open a Service Request (SR) with Oracle Support than to rely on the forum for an urgent reply! ;-)
Hope this helps,

Deserialization Error while invoking web service from JDeveloper 10g

When we tried to invoke a web service from JDeveloper version 10.1.3.4.0.4270, we got deserialization error.Here are the steps that we did to invoke the web service.
1. Using WSDL URL, downloaded WSDL file and associated XSD files into local machine using wsa.jar utility.
2. Using JDeveloper, created web service proxy project by referring the local WSDL file.Proxy got generated successfully.
3. Secured the proxy using "secure proxy" option.
4. Assigned all required values for parameters for web method.
5. When tried to invoke the web service, got deserialization error.
Exception in thread "main" deserialization error: java.lang.NumberFormatException

Process exited with exit code 1.
We think that the exact cause for the problem is as follows.
1. If we check the XSD file corresponds to response object, for one of the element, the type is decimal
<xsd:element minOccurs="0" name="ParentValueSetId" nillable="true" type="xsd:decimal"/>
2. In the SOAP response, this element is empty so during deserialization, the numer format exception occurred in LiteralSimpleTypeSerializer class.
Any help is greatly appreciated.

Hi Suresh & Mukesh,

If this does not work, then Oracle HSO will also not work.
Once you have confirmed that this is working, then configure the HSO service for Oracle.
If that fails, enables ODBC client tracing for that HSO service (in the init file for that service) to see exactly what ODBC calls Oracle is making and which of these are failing.

DB Link from Oracle to SQL Server error

Dear buddies,
I need to perfome some select on the tables which reside in SQL Server 2005 from Oracle 10g.
I followed the steps given in :
http://www.dba-oracle.com/t_heterogeneous_database_connections_sql_server.htm
I could perform a TNS ping which is successful but only when I perform a select I receive this error.
ERROR at line 1:
ORA-28545: error diagnosed by Net8 when connecting to an agent
Unable to retrieve text of NETWORK/NCR message 65535
ORA-02063: preceding 2 lines from SQLS
I have checked that my dsn name is in small caps all the way wherever it is used(Since its suggested in many sites).
Please guide me.
I am really looking ahead for a solution.
Regards,
Nith

use the like to setup ODBC and datasource

Retrieve data from a large table from ORACLE 10g

I am working with a Microsoft Visual Studio Project that requires to retrieve data from a large table from Oracle 10g database and export the data into the hard drive.
The problem here is that I am not able to connect to the database directly because of license issue but I can use a third party API to retrieve data from the database. This API has sufficient previllege/license permission on to the database to perform retrieval of data. So, I am not able to use DTS/SSIS or other tool to import data from the database directly connecting to it.
Here my approach is...first retrieve the data using the API into a .net DataTable and then dump the records from it into the hard drive in a specific format (might be in Excel file/ another SQL server database).
When I try to retrieve the data from a large table having over 13 lacs records (3-4 GB) in a data table using the visual studio project, I get an Out of memory exception.
But is there any better way to retrieve the records chunk by chunk and do the export without loosing the state of the data in the table?
Any help on this problem will be highly appriciated.
Thanks in advance...

Girish...Thanks for your reply...But I am sorry for the confusions. Let me explain that...
1."export the data into another media into the hard drive."
What does it mean by this line i.e. another media into hard drive???
ANS: Sorry...I just want to write the data in a file or in a table in SQL server database.
2."I am not able to connect to the database directly because of license issue"
huh?? I never heard this question that a user is not able to connect the db because of license. What error / message you are getting?
ANS: My company uses a 3rd party application that uses ORACLE 10g. And my compnay is licensed to use the 3rd party application (APP+Database is a package) and did not purchased ORACLE license to use directly. So I will not connect to the database directly.
3.I am not sure which API is you are talking about, but i am running an application of the visual studio data grid or similar kind of controls; in which i can select (select query) as many rows as i needed; no issue.
ANS: This API is provided by the 3rd party application vendor. I can pass a query to it and it returns a datatable.
4."better way to retrieve the records chunk by chunk and do the export without loosing the state of the data in the table?"
ANS: As I get a system error (out of memory) when I select all rows in a datatable at a time, I wanted to retrieve the data in multiple phases.
E.g: 1 to 20,000 records in 1st phase
20,001 to 40,000 records in 2nd phase
40,001 to ...... records in 3nd phase
and so on...
Please let me know if this does not clarify your confusions... :)
Thanks...
