  Prakash,
  You can use the database for ODBC (DG4ODBC) 11g gateway to connect to MySQL from Oracle.
  See the following notes in My Oracle Support for more details and information-

  Note to master note.1083703.1 for the Oracle Gateway products

  Note.233876.1 Connection Options abroad of banks of data and databases non-Oracle

  Hello

  I realize that your problem is that 10.2 HSODBC was never focused on the Windows 64-bit platform and was only available on 32-bit Windows.  You can not install the 32-bit on WIndows 64-bit HSODBC.

  Your only option is to install 11.2 DG4ODBC on your platform Windows 64 - bit, or if you have a RDBMS 10.2 installed on another platform, then you could use HSODBC as part of this installation and connect from the RDBMS on Windows 64 - bit using the links in the database.  HSODBC 10.2 software could not be installed as a stand-alone product and was only available as part of an RDBMS install.

  Kind regards

  My database is Oracle 11 GR 2 Rac 2 knots and on 64-bit Linux operating system.
  Version of my MySQL database is 5.5.17 it's the Linux 32-bit operating system.

  (7) then in the tnsnames.ora file, I added the following entry:

  When I test tnsping, it works.
  
  (8) I change the file .bash_profile for Oracle
  ORACLE_HOME, ORACLE_BASE were already pointing to the right destination, I added:
  
  LD_LIBRARY_PATH=/usr/local/lib:/U01/app/Oracle/product/11.1.0/Db_1/lib:/U01/app/Oracle/product/11.2.0/dbhome_1/HS/lib:/usr/lib64:/usr/lib

  Export ODBCINI
  
  ODBCINSTINI=/etc/ODBC.ini
  export ODBCINSTINI
  
  ODBCSYSINI = / etc
  export ODBCSYSINI
  
  (9) then I configured $ORACLE_HOME/hs/admin/inithsodbc.ora
  And modified these lines:
  HS_FDS_CONNECT_INFO = test
  HS_FDS_TRACE_LEVEL = WE
  HS_FDS_TRACE_FILE_NAME = odbc_test.log

  HS_FDS_SUPPORT_STATISCTICS = FALSE
  HS_LANGUAGE = AMERICAN_AMERICA. WE8ISO8859P1
  Set = /etc/odbc.ini ODBCINI
  
  (10) then I created a link of database with the following command:
  Create a database connection test audience to connect to test identified by test using 'test '.
  
  Also I tried the username and password in the database link with double quotes.
  
  (11) now finally when I try to select records from a mysql table:
  Select count (*) from "table"@"test" -I tried with and without double quotes
  
  I get the following error:
  
  ERROR on line 1:
  ORA-28500: connection between ORACLE and a non-Oracle system has sent this message:
  ORA-02063: preceding the TEST line
  
  How to pass through this error and how do I check the logs for HS?
  
  Your help is needed.

  Hello
  You had your listener.ora for the DG4ODBC entry-

  (ENVS = LD_LIBRARY_PATH = usr/local/lib:/u01/app/oracle/product/11.2.0/dbhome_1/lib)

  but it should also include the path to the driver manager directory which in your case is/usr/lib64 might then you add this?
  The error:

  Unable to load the ODBC library symbol: usr/lib64/libmyodbc3.so(SQLSetDescRec)

  indicates the lib64 directory are not accessible.

  The entry should look like-

  (SID_DESC =
  (PROGRAM = dg4odbc)
  (ORACLE_HOME = u01/app/oracle/product/11.2.0/dbhome_1)
  (SID_NAME = test)
  (ENVS = LD_LIBRARY_PATH = usr/local/lib:/usr/lib64:/u01/app/oracle/product/11.2.0/dbhome_1/lib)
  )

  Spaces may have bene lost at the time of publication, but at least there should be a space in the file as indicated by the .
  After the change is made and then stop and start the listener.
  If you still have problems, please post again the current versions of the configuration files, the complete errors figure in SQLPLUS to a select statement and the output of a trace debugging with errors.

  According to the information you use the 3.51 MySQL ODBC driver so could you also try with the latest version of the 5.1 driver and see if you have the same problem?

  Kind regards

• Migration from MySQL to Oracle SQL does not

  Hello everyone,

  I am new to Oracle SQL, but since our MySQL database is more and get more slowly, I would like to test the performance of Oracle SQL.

  So, I downloaded the current Oracle Linux distro and installed Oracle Database 11 g Express Edition.

  I connected with Oracle SQL Developer and started to migrate the MySQL database by following each step of this tutorial.

  I had to abandon all the privileges of the user migration (otherwise the creation and the deleteion of the migration repository did not) and I have disabled the migration of constraints to make migration work.

  Then I proceeded through all of the steps of the tutorial and ended with a "successful migration.

  The last step of the tutorial, it was to connect to the db migrated (using a combination of username/password generated name), it was not possible.

  What do I already checked?

  • Logged on as user system, I see that there is no new user created for the migrated db
  • Looking at the overview in the migration repository I see 3 phases, not knowing if the third displays an error or if it is not necessary at all (I got 58 tables in the db of the source)
    • Capture of 58/58
    • Convert 58/58
    • Compile 0/58

  From here, I don't know where to look for additional errors.

  I still can't use the migrated db and so I can't go forward with my tests.

  I missed something?

  I would appreciate your help.

  Astaldo

  Astaldo salvation,

  First, you must use SQL Developer 4.0.2 If you aren't already. It is available for free on OTN

  http://www.Oracle.com/technetwork/developer-tools/SQL-Developer/downloads/index-098778.html

  There are two ways to convert tables from MySQL to Oracle.

  1) copy to Oracle

  (2) migration to Oracle.

  Copy to Oracle is the simplest method. It does not imply the creation of a repository of migration.  But it only migrates data without constraints or default values or indexes and tables. The set of data to move should be reasonably low as it is moved on JDBC.

  It may suit your purpose to try to Oracle.

  http://dermotoneill.blogspot.co.UK/2010/11/copy-to-Oracle.html

  Migrate Oracle requires the implementation of a migration repository. But he migrate the default settings, constraints, and indexes and can also provide scripts offline data move that can manage the circulation of large data sets.

  Here is a small script to create a new MIGRATIONREPO user, and grant the correct privileges.

  CREATE USER MIGRATIONREPO IDENTIFIED BY oracle.

  ALTER USER MIGRATIONREPO QUOTA UNLIMITED ON USERS;

  GRANT CONNECT, RESOURCE, CREATE VIEW, CREATE MATERIALIZED VIEW to MIGRATIONREPO;

  Then using SQL Developer, create a connection to MIGRATIONREPO, right-click on the connection and choose "associate the Migration repository.

  I hope you have success best creation of migration with the privileges of theses repository.

  Migration Wizard step 8: target database

  Choose Offline Mode.

  This will present you with a build script that you can inspect before the race.

  The build script must be run using the SQL Developer worksheet and choose free user sufficiently privileged in Oracle generally SYSTEM.

  Note that if you would rather work with the repository you must currently you can browse your browser of Migration.

  Access converted database objects, right-click and select "generate the target".

  This will again open the Migration Wizard in step 8. Allowing you to choose Offline Mode so that you can review the build script.

  Hope this helps,

  Kind regards

  Dermot.

• MySQL for Oracle Database Migration

  I'm migrating 75 Tables of MySQL (5.0.18) to Oracle (10.2.0.1.0) using SQL-Developer (2.1.1.64)
  
  Below are the steps to follow to a State where I'm stuck:
  
  1: opens a connection with MySQL (5.0.18) which has * 86 * databases.
  2: open another connection with Oracle (10.2.0.1.0); a new installation.
  3: just clicked one of the MySQL database and selected ' + * Capture schema * + ".
  After the capture, this particular database appeared on ' + * models Captured * + ".
  4: right-click on this model converted, that says "* [email protected]:3306 (MySQL), etc. * ' and selected ' + convert model Oracle +".
  5: nothing appeared on the "* Converted models."
  
  ~~~~~~~~~~~ Stuck ~~~~~~~~~~~
  
  Another thing:
  -If I select different tables of the database under "* models Captured *" and then convert them then ' * SQL Developer * "generate converted models.
  -If I repeat anyone else of tables "* Converted model *" are generated.
  
  Am I suppose to repeat this step for each Table, the trigger, view etc.?
  
  Thank you

  Which JDK version do you use?

  There is a problem with SQL Developer 2.1.1 with JDK1.6 less than 18 years of age and older, during the conversion of a migration phase, with exactly the symptoms you describe.

  If you use one of these JDK could you try to install JDK1.6 U17?

  can anyone help?
  
  Ikrischer

  Ikrischer,
  On which platform do you have installed the drivers 32 bit and HSODBC? He was on a Windows 32-bit platform? It is not supported to run the 32-bit software on a Windows 64-bit platform.
  There were some problems with versions 10.2.0.3 and earlier that are similar to those you typo - problems with bigint and select count. These are laid down in the 10.2.0.4 group of patches, so you should apply to your ORACLE_HOME 10.2 directories and see if the problem still occurs.
  However, as already said HSODBC 10.2 is now desupported you need to find to install 11.1.0.6 DG4ODBC and then apply the 11.1.0.7 patch group which also solves the problem.
  If you have access to My Oracle Support then see this note.

  Select columns MySQL Bigint use HSODBC returns an incorrect value when you use ODBC MySQL Connector (Doc ID 401086.1)

  Kind regards

• How to migrate from MySQL to Oracle stored procedure

  Hi all

  I've migrated mysql 5.1.42 - enterprise-gpl-advanced DB for oracle sqldeveloper 3.1.07 tool.

  I checked .sql and files... Capture process not captured SQL stored procedures.

  Could you please suggest where I can check correct error or how to fix this.

  Thanks in advance.

  Hello

  SQL * Developer version you use is an old and you must use the latest version available from this link.

  Oracle SQL Developer

  However, even the v4 version does not support the migration of procedures stored as stated in this link - MySQL

  http://www.Oracle.com/technetwork/developer-tools/SQL-Developer/supportedmigplatforms-086703.html

  You will need to manually convert the MySQL in Oracle format, stored procedures since even the "Scratch Editor" under "tools - migration '-doesn't have an option for MySQL conversion.

• MySQL to Oracle using LKM SQL to Oracle, poor performance

  Hello

  I'm on the underside of technology.

  I'm try to use ODI to import data from MySQL to Oracle using the LKM SQL to Oracle, it works well for small amounts of documents but once volumes go higher it performs very badly.

  I'm replacing an integration of existing HS dblink to 44 seconds and ODI is 9 minutes.

  The MySQL and Oracle DB are on the same host with an autonomous ODI agent on the same host.

  MySQL 5.6.21

  Oracle 11.2.0.4

  Oracle Data Integrator 12.1.3

  I may try a different approach to dumping the MySQL table to a flat file and import from external table or sqlldr but y at - it a way to make the LKM SQL for Oracle perform better?

  Hello

  This problem has been resolved.

  I was setting the table sizes in batches on the data source server, after you set the values on the target data server is it now works as expected.

  Using a value of 5,000 for the two tables has reduced the operating time of 9 minutes to about 40 seconds.

  With Oracle, you should be able to just write the same thing as usual, except for the include link database when you reference the table for example your SQL

  insert into tablename@mysqldblink...

  updating of the game tablename@mysqldblink...

  Services gateway through the database link (odbc drivers or anything else that is used) must make the most of the necessary conversions for you.

• Check the connection to a remote Oracle database

  
  Hello

  I have an application that runs on a server that connects to an Oracle database on another server.  The application uses Java and JNDI to connect, there is no Oracle client installed on the server hosting the application.  The application seems to have been to connect to the database on the other server.  How can I check that the connection to the database still work from the server hosting the application?  Is there a software tool that I use does not require Oracle client must be installed.

  Thanks in advance

  the connection request is saved in the file listener.log on the DB server
