Connecting Oracle 11g with MySQL 5.1

Hey all,
I've been looking all over the web for this, and I can't find any information that applies to my case. I have an Oracle 11g DB setup on a Windows Server 2003 SP2, and have installed the Heterogeneous services ODBC driver. I want to connect this to another Windows 2003 SP2 machine that runs MySQL Community.
On the Oracle side, I have configured the ODBC Systems connection to MySQL, and it connects successfully. I have also configured tnsnames.ora as follows:
mysqlecommerce=
(DESCRIPTION=
(ADDRESS=
(PROTOCOL=TCP)
(HOST=dvlps11.cosine.com.cy)
(PORT=1521)
(CONNECT_DATA=
(SID=mysql_gateway))
(HS=OK))
I have initmysql_gateway.ora with the following two lines:
HS_FDS_CONNECT_INFO = mysqlecommerce
HS_FDS_TRACE_LEVEL = ODBC
and I have included the following into the listener.ora file:
SID_LIST_LISTENER=
(SID_LIST=
(SID_DESC=
(SID_NAME=mysql_gateway)
(ORACLE_HOME=C:\Oracle11g\product\11.1.0\db_1)
(PROGRAM=dg4odbc)
I have also created a dblink as follows:
create public database link "MYSQLECOMMERCE"
connect to MYSQLDB
identified by "<pwd>"
using 'mysqlecommerce';
Now when I try to run a simple SQL selection such as:
select "id_category" from "ps_category"@mysqlecommerce
I get the following reply:
ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
[MySQL][ODBC 5.1 Driver][mysqld-5.1.36-community-log]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 '"id_category" FROM "ps_category" A1' at line 1
ORA-02063: preceding 2 lines from DG4ODBC
Can anyone please help me understand what is going on?
Thank you in advance!

The syntax error is caused by your MySQL database not running in ANSI mode. By default DG4ODBC sends ansi compliant code to the foreign database and this means for case sensitive column and table names it surrounds them by double quotes. MySQL db not running in ANSI compliant mode rejects them and uses a back tick to preserver the case - thus it reports a syntax error in case of double qoutes.
To solve the issue please have a look at My Oracle Support note:
Problems Selecting Mysql Data Using 11.1.0.6 DG4ODBC - Error In Your SQL Syntax [ID 553030.1]

DB connection issue for Oracle 11g with jdk1.3

Hi Experts,
I have jdk1.3 installed. I need to connect to Oracle 11g, but there is no driver class for Oracle 11g with jdk1.3. I have Classes12.jar for Oracle 9i with jdk1.3. When I try to connect to Oracle 11g with jdk1.3 using Classes12.jar, I get the below error
Error:

Please help to solve this issue. This is urgent.
Thanks.

"connection refused" is quite a clear error message;
- either you configure a wrong host name or port number
- the database isn't even running
- a firewall is blocking you
In any case no connection can be made to the database, which is hardly a programming or driver problem. You'll have to figure out for whatever external reason you cannot create a connection to the database. Good luck.

DB2 8.1 to Oracle 11g with SQL Developer 3.0

Hi,
I started migrating my DB2 8.1 to Oracle 11g, with SQL Developer 3.0
Basically, I need to migrate TABLES.
I followed these steps:
1) I created a new Oracle database, tablespaces, users, etc.
2) Then, I created both (DB2 and Oracle) connections into SQL Developer 3.0. All works fine.
3) I start capturing one table with the "Copy to Oracle" feature. Done with no errors.
But when I compare the table structure, I see the following problems in Oracle:
a) All fields are NULLABLE = YES. SQL Developer show this field property correctly in DB2: NULLABLE = NO, but not migrated the same!
SOLUTION: All I want is that SQL Developer simply migrating the same value who I have in the DB2. But how?
b) In DB2 I have one field property called COLUM DEFAULT. In Oracle this property is called DATA_DEFAULT. The SQL Developer show this field property correctly for the DB2 tables (for example: 0.0, ' ', etc), but don't migrated the same value! All fields are configured to DATA_DEFAULT = NULL.
SOLUTION: I think this occurs because NULLABLE is migrated with the value YES. Well, all I need is the same above...
NOTE: I tested the SWISSQL DATA MIGRATION software, and it works fine. All tables, field properties and data are migrated sucessfull. But this program is trial version!
Well, I think all of this are BUGS into SQL Developer.
Please, anyone to help me?
Regards,
Ylram

You listed a bunch of things but you didn't say what steps you actually performed and what the result was.
Did you 'Compile'the procedure? until you compile the procedure you can't debug it.
I just created a new procedure and when I select the body it displays in the 'Code' window on the right. But the 'Debug' icon is not enabled because the procedure was not compiled for debug.
When I compile it for debug the 'Debug' icon is now enabled.

Connecting Oracle 11g using Oracle 10g

Hi All,
I have installed Oracle 11g (11gR2) server on a Windows 2003 (win32) machine. It is very well connecting when I tried to login to that database using the below command
sqlplus test/test@oracle11g I tried to access the same server from a different machine where only Oracle 10g client is available. I get the following error.
ERROR:

Please advice if we can connect Oracle 11g server using a Oracle 10g client from a different machine??
If Yes, Please advice whay am I getting the above error.
Thanks in Advance!!

With respect to your suggestion, I have modified the Oracle 10g tnsnames.ora file as below, but it still throws the same error.

OBIEE 11G with MySql Issue Hierarchy is not working..

Hi,
i am using the OBIEE 11G with MySQL DB. i have sucessfully created the RPD. i created the Hierarchy in the RPD. this is the scerario i have created.
i have only one data column created_at. by using this column i create 3 more logical logical columns, which are Year,Month Name,Week and created Hierarchy by taking the these columns only.
when i am viewing the result by taking the hierarchy it throwing the error systax error"ou have an error in your SQL syntax; check the manual that corresponds to your MySQL server version".
but we selecting the year column it successfully nagvigating to the month level data but when selecting the Hierarchy directly it is unable to navigate from year to month.
please provide me the solution for this as soon as possbile i have an urgent requirement on this.
Thanks,

Hi,
Thanks for you post..
My Requriement is that we no need to create new columns we need to necessary columns in BMM layer only and we need to use them in Hierarchy.
Thanks,

11.2 is beta at the moment. There is no official release date so far.
As DG4ODBC is independant from the Oracle database (or the target database) you can use a 3 machine model:
On the first machine you have your Oracle database, on a second machine running 32bit Windows you can install DG4ODBC and on the 3rd machine you can run your foreign database.
If the SQL Server 2k is installed on a 32bit Windows machine, then you can also install DG4ODBC on this machine.
In general the connection from an Oracle database to the DG4ODBC machine is done using SDQL*Net. The listener responsible for DG4ODBC will then load the DG4ODBC executable which will connect to the SQL Server using SQL Server ODBC driver.

For starters, you make sure that there is even the possibility of a network connection between your client machine and the machine hosting the "remote system". What happens when, on the client machine, you issue a 'ping <ip address of remote system>'?

Connection pool issues with Mysql

Hi,
I have defined sufficient read connections (50) in the toplink configuration, I am finding toplink is not releasing the connections in Mysql, this is when run from Jboss App server.
Is anyone aware of toplink connection pool issues with MySql?
thanks

TopLink always closes connections, I cannot see how this could occur.
Please include your persistence.xml or sessions.xml. Also ensure you are closing your EntityManager or ClientSession, especially if using exclusive connections.
Also include the exception you are getting.

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

Is it Possible to connect oracle 10g with oracle forms 11g?

Hi,
I have installed Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 and Oracle 11g forms and reports....
My question is
Whether i can develop application using oracle forms 11g and using oracle 10g as backend connection......
If Possible then how to configure it......
Thanks.

That would depend on the exact version of Forms 11g you are referring to;
this document: http://www.oracle.com/technetwork/developer-tools/forms/oracle-forms-111210certmatrix-1886127.xls
is for forms 11.1.2.1 and indicates database 10.2.0.4 is certified with this version of forms. For other Forms versions this might be different (I don't know as I didn't look it up).
You whould do the SQL*Net config like you'd do it on any other oracle client:
Tnsnames.ora - Oracle FAQ
Sqlnet.ora - Oracle FAQ
except for reports where in the opmn.xml the TNS_ADMIN variable is set for the reports servers; so you'd have to place your config files under $INSTANCE_HOME/config as well.

Simple way to connect Oracle 11g XE with MS SQL Server 2000

Is there a simple way to access SQL server database/ Tables within from Oracle 11g XE (Windows-32bit) on same machine. I am a novice so kindly keep it simple. Thanks

To connect to a SQL Server you need to use an Oracle product called Database gateway for ODBC which uses a 3rd party ODBC driver to connect to the SQL Server.
The easiest set up is to install DG4ODBC release 11.2 on the SQL Server. How to configure the Database Gateway for ODBC is described in note:
How to Configure DG4ODBC (Oracle Database Gateway for ODBC) on Windows 32bit to Connect to Non-Oracle Databases Post Install [Document 466225.1]
when you install DG4ODBC on a 32bit Windows operating system and the instructions for a 64bit Widnows operating system can be found in this note:
How to Configure DG4ODBC (Oracle Database Gateway for ODBC) on 64bit Windows Operating Systems to Connect to Non-Oracle Databases Post Install [Document 1266572.1]
The database gateway for ODBC is available for free from here:
http://www.oracle.com/technetwork/database/enterprise-edition/downloads/index.html
Please make sure you select the 32bit or 64bit Windows operating system depending on the platform where you've installed the SQL Server and on which you now install the gateway and download the <win32/64>_11gR2_gateways.zip CD.
Once downloaded, unzip it and install it using the Oracle Universal installer. Make sure you select the product Database Gateway for ODBC (there's also a dedicated SQL server gateway called Database Gateway for MS SQL Server - this gateway is NOT for free and it requires a separate license).
