Heterogeneous Connectivity to Mysql

Hi Fellows.
I need to connect to a Mysql Database online from Oracle 10G (Create a link) I read some article regarding Heterogeneous Connectivity to other non Oracle Databases without ODBC or DNS. Does anybody has deploy this Oracle feature???? Does Oracle 10G has another choice to connect to other relational databases............If somebody has information to connect to Mysql Database wil be great!!!!
Thanks a lot.!!!!

I'm still really confused by why you're talking about DNS. DNS is just a mechanism for resolving host names into IP addresses and that happens only at connection time and only if you have specified a host name.
Yes, normally ODBC is not the most efficient API in the world-- it was designed as a least common denominator API and designed with SQL Server in mind. That said, if you want to use Heterogeneous Services, you would either need ODBC, OLE DB, or a Transparent Gateway. If you are under time constraints, I'm going to wager that you don't have the time and budget to go out an purchase a Transparent Gateway. So you'd either have to use ODBC or OLE DB. I do not know if there is a MySQL OLE DB provider that runs on SUSE-- I would tend to doubt it. Which leaves just ODBC, assuming you've got a MySQL ODBC driver that runs on SUSE.
Personally, I've used Generic Connectivity to connect to DB2 and SQL Server databases from an AIX box (using commercial ODBC drivers) and to Excel files from a Windows box. I've never personally connected to a MySQL database, though if you're talking about ODBC connections, it doesn't really matter what database you are connecting to.

Heterogeneous Connectivity to MySQL with ODBC 5.1

Hi,
I have a setup with an oracle 10g XE version on an windows Server 2003 together with a MySQL 5.5
I setup a Heterogeneous Link using MySQL ODBC 5.1.
Every time I select something from a mysql table all varchar and text fields ignored in result set.
so the
select * from project@sugarcrm
returns only the non text/varchar fields (dates,numeric)
the select name from project@sugarcrm where name is char fiels
returns ORA-00904 'name invalid identifier '
Thanks

Has anyone encountered similar issue while configuring dg4odbc....I never had trouble with hsodbc. Since hsodbc is desupported , We are evaluating dg4odbc and openlink odbc
drivers to establish connectivity to mysql and stuck at this point.
Any suggestion from gateway gurus ?
Thanks in advance,
Bhaskar

HS connection to MySQL fails for large table

Hello,
I have set up an HS to a MySql 3.51 dabatabe using an ODBC DNS. My Oracle box has version 10.2.0.1 running in Windows 2003 R2. MySQL version is 4.1.22 running on a different machine with the same OS.
I completed the connection through a database link, which works fine in SQLPLUS when selecting small MySQL Tables. However, I keep getting an out of memory error when selecting certain large table from the MySQL database. Previously, I had tested the DNS and ran the same SELECT in Access and it doesn't give any error. This is the error thrown by SQLPLUS:
SQL> select * from progressnotes@mysql_rmg where "encounterID" = 224720;
select * from progressnotes@mysql_rmg where "encounterID" = 224720
ERROR at line 1:

I have read the MySQL documentation and apparently there's a "Don't Cache Result (forward only cursors)" parameter in the ODBC DNS that needs to be checked in order to cache the results in the MySQL server side instead of the Driver side, but checking that parameter doesn't work for the HS connection. Instead, the SQLPLUS session throws the following message when selecting the same large table:
SQL> select * from progressnotes@mysql_rmg where "encounterID" = 224720;
select * from progressnotes@mysql_rmg where "encounterID" = 224720
ERROR at line 1:
ORA-02068: following severe error from MYSQL_RMG
ORA-28511: lost RPC connection to heterogeneous remote agent using
SID=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=10.0.0.120)(PORT=1521))(CONNECT_DATA=(SID=MYSQL_RMG)))
Curiously enough, after checking the parameter, the Access connection through the DNS ODBS seems to improve!
Is there an aditional parameter that needs to be set up in the inithsodbc.ora perhaps? These are current HS paramters:
# HS init parameters
HS_FDS_CONNECT_INFO = MYSQL_RMG
HS_FDS_TRACE_LEVEL = ON
My SID_LIST_LISTENER entry is:
(SID_DESC =
(PROGRAM = HSODBC)
(SID_NAME = MYSQL_RMG)
(ORACLE_HOME = D:\oracle\product\10.2.0\db_1)
Finally, here is my TNSNAMES.ORA entry for the HS connection:
MYSQL_RMG =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.0.0.120)(PORT = 1521))
(CONNECT_DATA =
(SID = MYSQL_RMG)
(HS = OK)
Your advice will be greatly appeciated,
Thanks,
Luis

First of all please be aware HSODBC V10 has been desupported and DG4ODBC should be used instead.
The root cause the problem you describe could be related to a timeout of the ODBC driver (especially while taking care of the comment: it happens only for larger tables):
(0) [MySQL][ODBC 3.51 Driver]MySQL server has gone away (SQL State: S1T00; SQL
(0) Code: 2006)
indicates the Driver or the DB abends the connection due to a timeout.
Check out the wait_timeout mysql variable on the server and increase it.

Connection to MySQL via ODBC not working

Hello all together,
I've got a problem with the ODBC connection to MySQL. The connection via ODBC is established and things like tnsping are working.
When I select some data within the SQL*Plus environment, I get no real result. For example "select table_name from all_tables@mysql;" returns nothing.
My entry in listener.ora:
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME=odbc_mysql)
(ORACLE_HOME=D:\oracle\product\11.0.1\db_1)
(PROGRAM=dg4odbc)
My entry in tnsnames.ora:
MYSQL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
(CONNECT_DATA = (SID=odbc_mysql))
(HS=OK)
The initodbc_mysql.ora in ORACLE_HOME/hs/admin/:
HS_FDS_CONNECT_INFO = odbc_mysql
HS_AUTOREGISTER = TRUE
HS_DB_NAME = hsodbc
I tried some modifications but I still get no data from mysql database. When I try "select * from customer@mysql;" I get the correct number of records, the correct column names, but the content is always "¬¬¬¬". The odbc driver works, because with MS Access I can fetch the data. I'm using Oracle 11g Release 1 EE and MySQL ODBC 5.1.5.
What could be the reason for this?
Greetings,
Joerg

created in my UTF-8 Mysql DB your table and inserted a record; the select shows:
SQL> select * from "movieclass"@mysql;
idClass
ClassName
123
H e l l o
As you can see the content is there, the "space" between the letters is related to unicode. Each character is interpreted by 2 bytes and SQL*Plus wrongly displays both. Using iSQLPLus or SQLDeveloper does not show the "space" between the letters.
Here the data type mapping:
SQL> desc "movieclass"@mysql;
Name Null? Type
idClass NUMBER(3)
ClassName NOT NULL NVARCHAR2(50)
What's the exact version of DG4ODBC you're using? 11.1.0.7?
According to the listener file you're using DG4ODBC on Windows. There was a high/low byte issue in DG4ODBC for Windows. This issue is fixed in 11.1.0.7 and a certain patch. So I recommend you to get first the 11.1.0.7 patchset (if you don't already have it installed):
6890831 Oracle Database Family: Patchset
11.1.0.7.0 PATCH SET FOR ORACLE DATABASE SERVER 11.1.0.7.0
and then please apply also the latest patch:
8689191 Oracle Database Family: Patch
ORACLE 11G 11.1.0.7 PATCH 16 BUG FOR WINDOWS 32 BIT 11.1.0.7.0
There was a high/low byte issue

Can't connect PHP/MySQL 404 error

Wow, the learning curve is killing me. Yet another challenge. I'm using Dreamweaver CC and this tutorial http://www.adobe.com/devnet/dreamweaver/articles/setup_php.html
I'm at this step:
Open comments.php. You must have a PHP page open in the Document window to create a MySQL connection.
In the Databases panel (choose Window > Databases), click the Plus button on the panel and select MySQL Connection.The MySQL Connection dialog box appears.
Type connTest as the connection name.
For the MySQL Server, type localhost.If you are using the MAMP default ports on a Mac, use localhost:8889.
For the User Name, type phptestuser.
Type the password you chose for the phptestuser account in the Password field.
For the Database, type php_test.Note: You don't need to precede the underscore with a backslash here. It was inserted by phpMyAdmin in the previous section (see Figure 20) only because phpMyAdmin uses a query that permits wildcard characters.
Click Test.Dreamweaver attempts to connect to the database. If the connection fails, do the following:
Double-check the server name, user name, and password.
Check the settings for the folder Dreamweaver uses to process dynamic pages (see Specifying a Testing Server for Dreamweaver).
Verify that the web and MySQL servers are both running.
Temporarily disable any firewall or security program. If the connection works, you need to configure the security program to permit communication between Dreamweaver and MySQL.
Click OK. The new connection appears in the Databases panel.
Expand the connTest connection, and then expand the Tables branch. You'll see the comments table in the database, which you can expand to reveal the details of the table columns (see Figure 23).
As far as I can tell I have followed this tutorial to the letter.
As far as I can tell, XAMPP/php mySQL are all running fine, the files are in the correct place and everything should be working. However when I hit test I get a 404 error. (Same error when I hit the select button.)
The suggested problems on the 404 message are:
1. There is no testing server running on the server machine.
Pretty sure the testing server is running. Is there any way to test this, other than to note that xampp is definitely running right now and that I can log into phpMYadmin no problem?
2. The testing server specified for this site does not map to the http://localhost/php_test/_MMServerScripts/MMHTTPDB.php URL Verify that the URL Prefix maps to the root of the site.
Ummm...I'm pretty sure I put things where I was told to put them in the tutorial, but I'm lost at this point where I should verify what. A clue here? The files are where they are supposed to be, but maybe I entered something wrong? Except...I'm not sure what that could be or where to find it. Whatever IT is.
Everything in local files is looking good.
Thanks for your help!
PS: Extra points to anyone who figures out how to make copy/pasteable error messages! These buggers are the bane of my life!

Bgupta, you rock!
I hope you have copied the "mysql.php" and "MMHTTPDB.php" files from "C:\Users\username\AppData\Roaming\Adobe\Dreamweaver CC\locale\Configuration\Connections\Scripts\PHP_MySQL\_mmDBScripts" to "C:\xampp\htdocs\phptest\_mmServerScripts"
This was EXACTLY the problem. I checked the tutorial and I couldn't even find where the tutorial said to do this. (If I missed it, let me know where in the tutorial it was, please.)
Fixed!

There is idea how can resolve this problem

For all how have similar problem.
Decision instead of these ways

<%@ taglib prefix="sql" uri="http://java.sun.com/jstl/sql" %>
it is necessary to indicate these

How can I connect to MySQL external database

Hello.
I have a SAP system running in SQL Server 2003.
I need to connect to external MySQL DB., to operate with this information in ABAP program.
I have done the step necesary... I mean I go to DBCO transaction and configure the connection like this:
DB CONNECTION --> AFIS
DBMS --> MSS
user name --> xxxxxx
DBpass -->xxxxxx / xxxxxx
Conn Info -->MSSQL_SERVER=192.168.1.233 MSSQL_DBNAME=alliance OBJECT_SOURCE=alliance
I do a test program, when I do the statement CONNECT TO, sy-subrc 0 and connection = DEFAULT... I mean, with this form I cannot connect to MySQL Database...
Can you help me to do this?? I think the problem it's the connection string in DBCO... but I'm not sure...,
Would be possible to connect by MySQL ODBC??? I mean , installing the ODBC driver in my SAP server, and using this in ABAP Program??
Thks.
DATA: BEGIN OF wa,
cod_modelo(20),
END OF wa.
DATA: dbs TYPE dbcon-con_name.
DATA: con(20) TYPE c.
DATA : ls_wa LIKE wa.
con = 'AFIS'. "DB Connection in DBCO above
EXEC SQL.
CONNECT TO :con
ENDEXEC.
WRITE sy-subrc. ---> The result it's 4
EXEC SQL.
GET CONNECTION :con
ENDEXEC.
WRITE : con. --> The result it's DEFAULT
EXEC SQL.
SET CONNECTION DEFAULT
ENDEXEC.
write : con. --> The result it's DEFAULT

> It's for it, that when I go to DBCO... in DBMS ---... I can select Oracle, MSSQLServer, DB2... for this Databases..., exists the library (lib_dbsl)???
yes, for all those databases exists the database interface library.
> In resume:
> IT'S NOT POSSIBLE CONNECT TO MYSQL!!! ... I cannot believe it!!!...
Well - as far as I remember there were some times ago efforts to port SAP applications to MySQL. That would explain why there's also a file "DDLMYS.TPL" created if you execute R3ldctl during a system copy - amongst DDL files for all other databases. I believe this was at the time MySQL was promoting SAPDB/MaxDB.
MySQL is historically not a database engine for software, that requires transactional integrity; there were extensions to support that (InnoDB or others) and there was no customer demand in getting MySQL as engine for SAP applications. And only develop an interface to be able to connect to an external MySQL engine is not worth the effort.
However, there is hope Some BusinessObjects applications also run with and against MySQL engines, depending on how the strategy to integrate those into the SAP software stack there may (or may not) be an interface for that database in the future.

Connecting a MYSQL database in Dreamweaver

Hi All,
I'm tryting to connect a mysql database based locally and am getting the error:
HTTP Error Code 404 File Not Found. Here are some possible reasons for the problem:
1) There is no testing server running on the server machine.
2) The testing server specified for this site does not map to the http://localhost/_mmServerScripts/MMHTTPDB.php. Verify that
the URL Prefix maps to the root of the site.
What does this mean?
How do I start the testing server? I'm unable to locate the folder where the database files are stored as the database has been created locally on my machine. Everything hace been created locally so I know that point 2) could well be irrelavant.
Please can somebody help?
Many Thanks
Gordon

The functions for connecting to a database were mostly deprecated. But if you enable them in CS6 Cloud/CC then they will be the same.

Error when connecting to MySQL Database

I am trying to connect to MySQL and receive an error everytime. I have attempted to talk to Bluehost (who my site is hosted thru) and they said it is not on their end and not something they can help me with. I set up a new MySQL Database with Bluehost and then set up the site through DW and everything went fine. I secured an ftp connection and went on to connect to MySQL. When I enter in my credentials for SQL Database, it returns:
HTTP Error Code 404:
Reason 1. No testing server running on the server machine.
Reason 2. Testing server specified for this site deos not map to the http://my_domain.com/_mmServerScripts/MMHTPDB.php URL. Verify the URL Prefix maps to the site.
The testing server model I am using is set to PHP MySQL and URL Prefix I am using (my_domain.com) is my website URL. I watched a YouTube video someone suggested elsewhere on how to add MMHTTPDB.php and mysql.php files to _mmServerScripts folder since the folder is empty but unfortunately, those files are not found on my computer. I assume they were supposed to be installed when I installed DW, but they are not here. I have done a general search of the comp and looked in each folder that was installed with DW and sadly, no files that match those names. What can I do? How can I make an SQL connection? Please help. It is greatly appreciated.

Database error #2002 can not connect local mysql server to socket through '/var/run/mysqld/mysqld.sock'(2) on mac os x 10.9.2

Dear Fellas:
I received "database error #2002 can not connect local mysql server to socket through '/var/run/mysqld/mysqld.sock'(2)" on mac os x 10.9.2.

Please help!!

Fascinated and guessing:
Something related to sock(2) because that's not part of your copied info. I'm thinking you've doubled up on sockets and the second socket doesn't exist, meaning you should be connecting to the first socket "mysqld.sock" whether automatic or not.
I've only used GUI tools on purpose, so does this mean you've already got MySQL running and you tried to launch it again manually? Perhaps you already have one instance of a db and you're trying to launch a second instance, and the two can't coexist with a single user local db?
Assuming this is all local, I'd shut down the db service and restart it, out of hand. I've seen similar messages when I set the db to start up on boot, and it didn't finish shutting down when I tried to restart it manually. Usually the GUI won't let me turn it on because it reports it's already running, but in that case it hadn't finished performing what the GUI was reporting.
Just speculating.

Mysql_connect "Lost connection to MySQL..." error 61

A web developer is getting this error on a test web server of ours that is running 10.5.7 Server.
"Warning: mysql_connect() function.mysql-connect: Lost connection to MySQL server at 'reading initial communication packet', system error: 61 in..."
I've seen other postings online for this error suggesting that the line containing 'bind-address 127.0.0.1' be commented out within /etc/my.conf... but this line doesn't exists on my installation.
MySQL and php have been working well for other databases and developers. This is a newly created database.
Has anyone else seen this error and found a fix?
Thanks!

This is more than likely a firewall problem on your users end. I just ran into this when moving my servers to a colocation. Everything was fine until i tried to connect to an outside database from the machines behind the new firewall. was set to allow 3306 in, but not out. And would connect without issues to localhost:/var/mysql/mysql.sock .
from the machine trying to connect from try
shell> telnet <servername> 3306
should be able to login. if refused, then port is closed.
