Oracle Gateway for odbc to transfer CLOB to MySQL longtext type

Hi,
Does gateway supports transferring CLOB datatype to MySQL LONGTEXT. If so, How I can achieve this?
Please post an example.

It will work, but it is tricky as the longtext will be mapped to an Oracle long when using the gateway.
Sometimes a simple solution is to define a view that splits the data into chunks using substr. Also split the target column into chinks using a view an then use the view to transfer the data rather then the original table.
PL/SQL will also work but you need to pay attention to its limitations (64k). You also have to split the data into chunks. Other copy methods like SQL*Plus copy have its limitation. You really have to work out which solution fits for you best here.

Error fetching data from a foxpro db using Oracle Gateway for ODBC

Hi.
I have an 10.2.0.1 database an a 11.2.0 Oracle Gateway for ODBC installed and configured.
The dblink test works fine, I can connect with the foxpro database because if I execute desc centros I can see the
columns of table centros.
The problem comes when I try to execute Select * from centros@fox1;
A syntax error is returned ([Microsoft][ODBC Visual FoxPro Driver]Syntax error. {42000,NativeErr = 200})
I paste down the output of the trace file with HS_FDS_TRACE_LEVEL=255
If I run select codcen from centros@fox1; another error is shown. Tell me if you want the other trace file.
select codcen from centros@fox1

The first issue I see is that Oracle 10.2.0.1 was never certified with DG4ODBC 11. Only 10.2.0.4 or 10.2.0.5 can be used as the Oracle database HS kernel requires a gateway compatibility patch and this patch is included in 10.2.0.4 or 10.2.0.5 Oracle database patch set.
Then another error in the trace is that for each column description you have an error:
hgopoer, line 233: got native error 0 and sqlstate HY091; message follows...
[Microsoft][ODBC Visual FoxPro Driver]*Descriptor type out of range* {HY091}
Exiting hgopoer, rc=0 at 2012/05/31-13:11:28
hgodscr, line 615: calling SQLColAttribute got sqlstate HY091
It seems it is not critical as DG4ODBC continues, but a more detailed analysis would require an ODBC trace.
When looking at the table description it seems the column names are all in lower letters, for example: solar. So commonly Dg4ODBC needs to quote the names

and according to the trace the FoxPro ODBC driver doesn't like these quotes and reports a syntax error.
So this explains at least why select codcen from centros@fox1 will fail. In general the Oracle database is case insensitive and translates all object names to upper case and the select it will pass to the foreign database would be similar to:
select CODCEN from CENTROS => which will fail as FoxPro is case sensitive. So the error message ORA-00904 (missing column name) is correct and the statement you need to use is:
select "codcen" from centros@fox1;
But this might lead again to the Syntax error you got earlier => You need to check which sign (single quote, back tick, double quote) Foxpro uses to quote object names and then set the gateway parameter HS_FDS_QUOTE_IDENTIFIER accordingly.
To check which character can be used to quote column/table names you might use the Microsoft ODBc test utility which was distributed in the old MDAC 2.8:

Oracle optimizer and heterogeneous services (Transparent Gateway for ODBC)

Hi everyone!
We have the following configuration:
Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 - 64bit Production.
Oracle Database Gateway for ODBC 11.2.0.2.0 on the same machine as Oracle DB.
Non-Oracle DB installed on a different hardware accessed through Oracle Gateway for ODBC via dblink.
Now, we have to query the remote non-Oracle system and retrieve some data. For the sake of brevity let's suppose we have the following table in our non-Oracle DB:
create table test (
     ip_address varchar(15),
     start_time datetime,
     end_time datetime
And we run the following SQL query against the remote table on our Oracle DB:
SELECT start_time,end_time,ip_address
FROM remote_table@db_link
WHERE
end_time >= to_date('2011-10-11 00:00:00','rrrr-mm-dd hh24:mi:ss')
OR (
end_time IS NULL AND start_time >= to_date('2011-10-11 00:00:00','rrrr-mm-dd hh24:mi:ss')
AND start_time <= to_date('2011-10-12 00:00:00','rrrr-mm-dd hh24:mi:ss')
AND ip_address = '127.0.0.1';
But, having query monitoring on the remote DB enabled, we see that the actual query on the remote site looks like this:
SELECT "START_TIME","END_TIME","IP_ADDRESS"
FROM "REMOTE_TABLE"
WHERE "IP_ADDRESS"='127.0.0.1' AND "START_TIME"<=?
All references to END_TIME column are gone from WHERE clause for whatever reason.
However, Oracle execution plan shows us the following:
| Id | Operation | Name | Rows | Bytes | Cost (%CPU)| Time | Inst |IN-OUT|
| 0 | SELECT STATEMENT | | 1 | 27 | 200 (0)| 00:00:03 | | |
|* 1 | FILTER | | 1 | 27 | 200 (0)| 00:00:03 | | |
| 2 | REMOTE | REMOTE_TABLE | | | | | DB_LINK | R->S |
Predicate Information (identified by operation id):
1 - filter("END_TIME">=TO_DATE('2011-10-11 00:00:00','rrrr-mm-dd hh24:mi:ss') OR
"END_TIME" IS NULL AND "START_TIME">=TO_DATE('2011-10-11 00:00:00','rrrr-mm-dd hh24:mi:ss'))
Remote SQL Information (identified by operation id):
2 - SELECT "END_TIME","IP_ADDRESS","START_TIME" FROM "REMOTE_TABLE" WHERE
"IP_ADDRESS"='127.0.0.1' AND "START_TIME"<=:1 (accessing 'DB_LINK' )
This actually means that Oracle CBO decided that it will apply filter on END_TIME column after having retrieved the data from the remote site. We don't want this behaviour but have no idea how to affect execution plan in this case.
So, the question is: How can we force Oracle CBO to not change the initial query and pass it to the remote site "as is"? Is there any way we can achieve this goal?
Edited by: user12024904 on 28-Oct-2011 04:05

Hi,
Our Oracle DB and Gateway are running on the following system:
HP-UX B.11.31 U ia64
The following SQL code is executed in SQLPlus:
SELECT start_time,end_time,ip_address
FROM ip_acc_complete@gr_link
WHERE
END_TIME >= to_date('2010-10-21 00:00:00','rrrr-mm-dd hh24:mi:ss')
OR (
END_TIME is null AND START_TIME >= to_date('2010-10-21 00:00:00','rrrr-mm-dd hh24:mi:ss')
AND START_TIME <= to_date('2010-10-22 00:00:00','rrrr-mm-dd hh24:mi:ss')
AND IP_ADDRESS = '127.0.0.1';

The non-Oracle DB is CopperEye Retrieval Server with its own custom ODBC driver.
CopperEye query log shows that the following query is received from Oracle Gateway:
01/11/2011 14:26:31 - NEW QUERY :
SELECT "END_TIME","IP_ADDRESS","START_TIME" FROM "IP_ACC_COMPLETE" WHERE "IP_ADDRESS"='127.0.0.1' AND "START_TIME"<=?
which complies with the information in Oracle Gateway trace file.
So, it seems that it's Oracle DB decision to split the original WHERE clause into two parts, delegate one part to the remote site, retrieve the data and then apply the remaining filter locally.

How to configure distributed transaction in Oracle Database Gateway for ODBC? (ORA-02047)

I am connecting from Oracle to another database server (MS SQL Server, DB2 the error message is the same) through an ODBC connection using Oracle SQL Developer. (This is how I set up)
I want to query the schema of a non-Oracle database using the data dictionary mapping of the Oracle Database Gateway for ODBC.
This works well:
select * from all_tables@katimssql;
But this doesn't:
create table alltables_mssql as
select * from all_tables@katimssql;
Output:
Error report:
SQL Error: ORA-00604: error occurred at recursive SQL level 1
ORA-02047: cannot join the distributed transaction in progress
ORA-06512: at "SYS.HS$_DDTF_SQLTABLES", line 58
ORA-06512: at line 1
Does anyone know the solution of this?
Thanks in advance,
Kata

HS_TRANSACTION_MODEL = READ_ONLY

Hi Kata,
this won't work as the ALL_TABLES is not a table that exists in your SQl Server - instead it is a "mimicked" table. This means the gateway will check if you have on your SQL Server a table called all_tables and when there's no table it will start an internal mechanism to check out what sort of tables exist in your SQL Server database. So the gateway is starting internally another transaction to get details from the foreign database and DG4ODBC can't participate in distributed transactions at all. Instead of using all_tables you have to use a real SQL Server table like SQ Server sys.objects or sys.tables.

Oracle Database Gateway for ODBC with Oracle XE

Dear Colleague,
Is it possible to use the Oracle Database Gateway for ODBC in conjunction with the Oracle Express Edition (or does one have to use the Standard or Enterprise Editions)? If yes, are there any restrictions when using the Oracle Database Gateway for ODBC in the context of Oracle XE?
Best regards,
Randy

Hi,
As it says, as long as you have an RDBMS license then you do not need a separate license for DG4ODBC. If the confusion is where it says "Oracle Database Gateway for ODBC can be installed and used on a machine different" then that is just to clarify that you can run the gateway on a completely separate machine from where the licensed RDBMS is running, but you can also run DG4ODBC on the same machine where the RDBMS is installed.
If you install 11g DG4ODBC on the same machine where you have a 10g RDBMS then it must be installed into a separate ORACLE_HOME.
If this is still not clear then please get back and let us know exactly what you need clarifying.
Regards,
Mike

Oracle Gateway for MS SQL Server

I have a oracle 10g database installed on Linux platform. I have installed oracle 11g gateways in the same system in a different location other than that of ORACLE_HOME.
I have configured the initdg4msql.ora and configured the listener in the ORACLE_HOMEs listener.ora
When I try to query the SQL Server table with the db link then I am getting the following error
Error starting at line 1 in command:
select * from dbo.jobs@testlink
Error at Command Line:1 Column:23
Error report:
SQL Error: ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
[Oracle][ODBC SQL Server Driver][libssclient22]ConnectionOpen.[Oracle][ODBC SQL Server Driver]Invalid connection string attribute
ORA-02063: preceding 2 lines from TESTLINK
the following is my initdg4msql.ora configuration:
# This is a customized agent init file that contains the HS parameters
# that are needed for the Database Gateway for Microsoft SQL Server
# HS init parameters
HS_FDS_CONNECT_INFO=sqlserv:1433//pubs
# alternate connect format is hostname/serverinstance/databasename
HS_FDS_TRACE_LEVEL=DEBUG
HS_FDS_RECOVERY_ACCOUNT=RECOVER
HS_FDS_RECOVERY_PWD=RECOVER
can anyone tell me where am I going wrong?

the patch is not applied to 10g db. Here is the last few lines of the dg4msql trace file

Oracle gateway for Oracle 10g DB on Windows 64 bit server

Is there any place that I can find Oracle dateway for Oracle 10g DB on Windows 64 bit server? I can only find Gateway for Oracle 11g on Windows 32 bit server. Please help me to identify this. Thanks.

yingkuan:
Thanks a lot. The link tells the details. It seems that Oracle has not release Gateway for Oracle database 10.2.0.x on Windows 64 bit server. Probably they don't do it.
So under this circumstance, if I want to install Gateway (32 bit) on Oracle 10.2.0.3 DB on Windows 64 bit server for Teradata, I probably have to install Gateway software in another Oracle Home, then configure it right. Please give more advice on this. 32 bit Gateway will work for 64 bit database?

Oracle gateway for MS sql server 2005

Is Oracle 9i Gateway for MS SQL Server compatible with SQL 2005? If not what are the other options?

Check the support matrix at metalink.
But be advised that Oracle 9i is in desupport mode.

11g gateway for ODBC returns SYNTAX ERROR on query

Hi,
I have made a database link to an odbc link on a 11g gateway. The odbc driver for the database in question is called connx, a third party driver to connect to RMS files on an old vax. The odbc driver works fine as I tested it independently of the gateway.
The database link connection is fine. I do desc tablename and it returns the correct columns
I do for example select * from SICF090MLT@melt and it returns :
meltdb>select * from SICF090MLT@melt;
select * from SICF090MLT@melt
ERROR at line 1:
ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
Illegal identifier
A1."CHARGE_NO" , A1."MIX_ID" , A1."BUCKET_ID" , A1."AIM_ST" , A1."SCRAP_MIX_NAME" FROM << Syntax Error >> 'SICF090MLT' A1
ORA-02063: preceding 3 lines from MELT
As you can see all of the columns have been discovered by the query,
I am not sure what can be the issue. Maybe a character translation issue? Some configuration settings for the gateway? Any ideas?
On a side note: all other database links to other databases (sqlserver) work fine with this 11g gateway.
The Best to all of you!

Mireille,
I am using a win32 driver.
HS_FDS_SUPPORT_STATISTICS is false for all my database links. I have had issues with that in the past and have already learned my lesson :)
I will check the quoted identifier setting for my odbc link and change it if I can.
As a side note: for now I am using the DBMS_HS_PASSTHROUGH package to get around the problem, but it is better if I solve my original problem obviously. I will let you know.
Merci et bonne journée.

Oracle gateway for DRDA 12c for clusterware installation

Hi, We tried to install DRDA 12c on our RAC clusterware environment, but the 12c software install wont give us a screen like 11.2 which will ask us to select all the clusternodes. Can anybody help explain how we can do it?
I checked download pages, and only one available download.
Thanks.

Hi,
As Matt said you just need separate instance files in the gateway install directories, you don't need to install the gateway software more than once.
Have a look at this note -
How To Add A New Database or Destination To An Existing Gateway Configuration (Doc ID 1304573.1)
I'll follow up on why the install didn't copy the gateway binaries to the other node.
Regards,
Mike

Oracle gateways 11g

Hi
we have a oracle database version 11.2.0.1
now we have instlled database gateways 11g in sql server machine and created db link in oracle and working fine
Now my question is:
Windows 2003 server having sql server and 11g Gateways installed
But oracle database is 10g............if i create link in Oracle it will work?
because 11gR2 gateway will synch with Oracle 10g database.
Thanks
Shaik

Hi Joe,
yes it is possible. All you need is a suitable ODBC driver and the Database Gateway for ODBC.
There are documents available within the Oracle Support knowledge base (htp://support.oracle.com). As you didn't specify your preferred platform here a list of possible notes:

About Oracle Heterogeneous Services and Oracle Gateway

Hi All,
I am very new at this topic, I want to know:
1)Oracle Heterogeneous Services and Oracle Gateway same or not?Need license or not?
2)If want Creating Database Link from Oracle 11g to Sybase AS 15.5 Using Oracle Heterogeneous Services what drivers should I install from my pc(windows 7) and from my server(Linux red hat 5)?please give me link for this
3)Is there any link Step by step to configure odbc until creating dblink?
4)what more convenient, connect sybase from Oracle Heterogeneous Services or Oracle Gateway?
Thank you so much for your help
Regards
JOE

Joe,
let copy/paste your questions and comment inline:
1)Oracle Heterogeneous Services and Oracle Gateway same or not?Need license or not?
Let me first clarify one thing, heterogeneous services is the generic mechanism in the Oracle database used by all gateways. The product you are talking about is the Database Gateway for ODBC or the Database Gateway for Sybase.
The Database Gateway for ODBC is available for Linux and Windows. It is the free product which does not require an Oracle license. The license is included in your database license. It is a generic gateway which allows you to connect with any suitable 3rd party ODBC driver to a matching foreign database. As it is a generic connectivity which aloows you to connect to real databases but also to MS Excel or even Text files as long as you have a suitable ODBC driver, its capability is very limited.
The more powerful gateway is the Database Gateway for Sybase. It covers the same functionality as DG4ODBC but it allows you also to work with distributed transactions, it allows you to call remote Sybase stored procedures etc. This gateway is design for Sybase ASE connections, so it is also able to map certain Oracle functions to Sybase equivalents. This Database Gateway for Sybase is NOT for free, it requires an additional license.
2)If want Creating Database Link from Oracle 11g to Sybase AS 15.5 Using Oracle Heterogeneous Services what drivers should I install from my pc(windows 7) and from my server(Linux red hat 5)?please give me link for this
That depends on your preferences. Both gateways are available for Linux and for Windows. When using DG4ODBC you only need to pay attention that you get a suitable 3rd party ODBC driver for this platform with the matching word size (64bit for 64bit DG4ODBC and 32bit ODBC driver for installations of DG4ODBC on 32bit platforms).
The latest software release is currently 11.2.0.3 and it can be downloaded (and installed from scratch) from "My Oracle Support". Just open the Patches & Updates section, look for Patch 10404530: 11.2.0.3.0 PATCH SET FOR ORACLE DATABASE SERVER and make sure to choose the platform you want to use. Then check out the readme as it lists which of these download CD's contains the gateway software.
BTW, the CD contains DG4ODBC and DG4SYBS and it is up to you to decide during the installation which product you want to use.
3)Is there any link Step by step to configure odbc until creating dblink?
The ODBC driver installation differs from vendor to vendor and platform to platform - so we don't have a specific note how to configure the ODBC driver. This kind of question is better handled by the ODBC driver vendor.
Regarding the set up of DG4ODBC on Windows you find suitable information in the knowledge base on My Oracle Support. Just look for:
How to Configure DG4ODBC (Oracle Database Gateway for ODBC) on Windows 32bit to Connect to Non-Oracle Databases Post Install          [Document 466225.1]
and for DG4SYBS:
How to Configure DG4SYBS (Oracle Database Gateway for Sybase) on 64bit Unix (Linux, AIX, HP-UX Itanium and Solaris) Post Install          [Document 437696.1]
How to Setup DG4SYBS (Database Gateway for Sybase) on a 64bit Windows          [Document 1319852.1]
4)what more convenient, connect sybase from Oracle Heterogeneous Services or Oracle Gateway?
It really depends on your needs. DG4SYBS is surly easier to install as this gateway comes with everything you need and you do not have to find a suitable ODBC driver nor get the ODBC driver working. It is also more powerful as you can for example use triggers that replicate data changes in an Oracle database to the Sybase database within the same transaction. When you want to call Sybase stored procedures you can also do that with DG4SYBS. So it really depends on your needs.

Opening a secure web page from oracle forms for credit card validation

Hi All,
I searched for the topic in the forms forum but couldn't find a solution.
Requirement: As per some compliance, our application cannot do a credit card validation from our forms application, instead we need to use a java code which a third party will provide ,it's an iframe (they say, i am layman when it comes to Java, don't know what is it), but they say that, within your forms application you call our iframe do the credit card validation over there get a token of response back from us and use this token as a confirmation in your application.
Problem: I could not find a solution anywhere wherein i can call a web page from forms. Now, this web page should be modal, i.e. unless i close this page i cannot access my forms application. Please guide me if anyone has done that.
Secondly if i could make it work, how will i communicate with this external web page, like getting back some token value and use it back in my forms application. I am completely clueless.
As we are using Oracle designer for generating forms, we cannot use a bean type thing as designer does not have the bean-item type defined!
Appreciate if anyone could provide me pointers for a solution to this problem statement.
We are on forms 9i -- Version 9.0.2.11.0
Edited by: the_wing_rider on Jul 8, 2011 5:10 AM

The simple way to do it is to use a PJC (java bean) + apache httpclient library..
If you have a webservice than you can use Axis library and wsdl2java to create java classes from wsdl.
also you can use httpclient library to simulate http protocol (request/response actions)..
(for example.. you have a credit card number.. you post this number to specified URL and then you parse the response from credit card validation server)..
Post here some documentation (specification) on how to call the credit card validation .. (maybe it's a secure webservice?)
Here you have a httpclient library documentation:
http://hc.apache.org/httpcomponents-client-ga/tutorial/html/index.html
Also you can implement bean area in designer.. If you need help I can post here how we do it in our project..
also look here: Call webservice from PJC over https protocol

Oracle 9i on LINUX Transparent Gateway for SQL Server

Does anybody know if there is a Transparent Gateway available for Oracle 9i on LINUX to connect to SQL Server? I have run the installer and cannot seem to find the install options for any Transparent Gateways. I am familiar with their location in the universal installer as I have installed the Oracle/SQL Server Transparent Gateway with Oracle in WinNT. Perhaps Transparent Gateways for Oracle/LINUX are not available?
Thanks in advance.

I have the same issue - we want to upgrade our 9.2 to 10g Linux, and need to maintain connectivity to some legacy sqlserver databases. I can't find any mention of tg4msql for linux. What gives? Anyone know the answer to this? thanks, michael
