MySql to Oracle DB Migration, creating schema problem

Hello
Im a beginner, try to migrate a mysql database in oracle. The mysql db contains a few tables, if im trying to migrate everything manually.
When filling out the tables a problem im. It's as follows:

Table 1 has a Key (t1_col1, t1_col2, t1_col3) primary Composite.
Table2 contains a column (t2_col1), which is a reference to Table1 t1_col1 (to make t1_col1 a repository key in the other table must be UNIQUE or PRIMARY, but as we know table can have a unique primary key and the t1_col1 contains redundant data, so cant make UNIQUE either).
So I tried indexing of the t1_col1 column but it dint seem to work as well, creating table2 it gives "no unique match or primary key for this list of columns.
".

I think that MySql is not so strict a lot compared to Oracle, please guide me through this, any workaround (s)?
This is the MySql schema:

CREATE TABLE "temp". "table1")
't1_col1' varchar (50) NOT NULL,
't1_col2' varchar (50) NOT NULL,
't1_col3' varchar (50) NOT NULL,
"t1_col4" integer NOT NULL,
PRIMARY KEY ('t1_col1', 't1_col2', 't1_col3')
)
ENGINE type = InnoDB
CHARACTER SET utf8 COLLATE utf8_general_ci;

CREATE TABLE "temp". "table2")
't2_col1' varchar (50) NOT NULL,
't2_col2' varchar (50) NOT NULL,
FOREIGN KEY CONSTRAINT 'table2_fk1' 'table2_fk1' ('t2_col1')
REFERENCES, 'table1' ('t1_col1')
ON DELETE CASCADE
ON UPDATE CASCADE
)
ENGINE type = InnoDB
CHARACTER SET utf8 COLLATE utf8_general_ci;

Looking forward to the answer.

Kind regards
Peter

If I didn't know that MySQL allows you to declare FK constraints that are non-profit information only and does not apply, I would find this surprisiing really, since the essence of a FK relationship is that the child is identified by the parent.

In Oracle, you must create a primary key for the substitution on the table1 based on the unique combination of col1, col2 and col3. I would certainly use a sequence for it. Next, you create a unique constraint on col1, col2 and col3 to apply your natural primary key. FK in table2 would be the key to substitution from table1. Something like:

CREATE TABLE table1 (
   t1_surr_key NUMBER NOT NULL,
   t1_col1 Varchar2(50) NOT NULL,
   t1_col2 Varchar2(50) NOT NULL,
   t1_col3 Varchar2(50) NOT NULL,
   t1_col4 integer NOT NULL)

ALTER TABLE table1 ADD CONSTRAINT table1_pk
   PRIMARY KEY (t1_surr_key);

ALTER TABLE table1 ADD CONSTRAINT table1_uk
   UNIQUE (t1_col1, t1_col2, t1_col3);

CREATE TABLE table2 (
   t2_col1 varchar2(50) NOT NULL,
   t2_col2 varchar2(50) NOT NULL,
   t1_surr_key NUMBER NOT NULL,
CONSTRAINT table2_fk1 FOREIGN KEY (t1_surr_key)
   REFERENCES table1 (t1_surr_key)
   ON DELETE CASCADE
   ON UPDATE CASCADE)

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

Also the * 'Script' * output even * "name of the constraint *; Viz

+ Cdr5 ALTER TABLE ADD CONSTRAINT PRIMARY PRIMARY KEY (table_id) ENABLE; +

Constraint must have derived the name of the table. Otherwise, you will have repeated migrations:

Error report:*.
SQL error: ORA-02264: name already used by an existing constraint
+ 02264. 00000 - 'name already used by an existing constraint ' +.
* Cause: The specified constraint name must be unique. +
* Action: Specify a name for the constraint unique constraint. +

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?

Migration - MySQL to Oracle - do not generate data files
Hello

I have been using the SQL Developer migration Assistant to move data from a MySQL 5 database to an Oracle 11 g server.
I used it successfully a couple of times and its has all worked.

However, I am currently having a problem whereby there is no offline data file generated. Control files and all other scripts generated don't... just no data file.
It worked before, so I'm a bit puzzled as to why no logner work.

I looked at newspapers of migration information and there is no errors shown - datamove is marked as success.
I tried deleting and recreating rhe repository migration and checked all grants and privs.

Is there an error message then it would be something to continue but have tried several times and checked everything I can think.

I also tried the approach of migration command-line... same thing. Everything works fine... no errors... but only the table creation and control script files are generated.
The schema of the source is very simple and there is only the tables to migrate... no procedure or anything else.

Can anyone suggest anything?

Thank you very much
Mike
Hi Mike,.

I'm so clear.
You use SQL Developer 3.0?
You walked through the migration wizard and choose Move Offline mode data.
The generation of DDL files are created as are the scripts to move data.
But no data (DAT) file is created and no data has been entered in the Oracle target tables.

With offline data move, Developer SQL generates (saved in your project, under the DataMove dir directory) 2 sets of scripts.
(a) a set of scripts to unload data from MySQL to DAT files.
(b) a set of scripts to load data from the DAT files in the Oracle target tables.
These scripts must be run by hand, specifying the details for the source databases MySQL and Oracle target.

"no offline data file generated. Control files and all other scripts generated don't... just no data file. »
«.. . but only the creation and control file table scripts are generated. »

What you mean
(1) the DAT files are not generated automatically. This should, if we need to run the scripts yourself
(2) after manually running the scripts that the DAT are not present, or that the DAT files are present, but the data does not load in Oracle tables.
(3) the scripts to move data in offline mode does not get generated

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 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

MySQL to Oracle Migration offline: scripts incorrectly generated for tables
Hello

I used SQL Developer 3.0.4 to migrate Mysql to Oracle databases.

I have the following errors on the charger (oracle_ctl.sh) scripts to run:

SQL * Loader-2026: the charge was dropped because SQL Loader cannot continue.
SQL * Loader-500: could not open the file (data / framework_perdadepacotes_diari.txt)

The "framework_perdadepacotes_horario.txt" dump file is generated by mysqlsdump with the original mysql table name and ".txt" sufix:
-excerpt from unload_script.sh
mysqldump-u $username - p $server h $ t socket=/u01/mysqlmulti/mysql2/mysqld2.sock port password data = 3312 fields terminated by = "< EOFD >" fields escaped by = ""-lines terminated by = "< EORD >" "dxdb" "framework_perdadepacotes_horario" "

but sql loader controlfile makes reference to the file by using the new name of the oracle table (in this case, that the new name is truncated to 30 characters):
--
load data
INFILE ' data / framework_perdadepacotes_diari.txt ".
"str"< EORD >"
in the dxdb.framework_perdadepacotes_diari table

Another instance of the same problem, but in this case the table name starts wth "_":
-of unload_script.sh
mysqldump-h $server u $username - p$ password t data fields terminated by = "< EOFD >" fields escaped by = ""-lines terminated by = "< EORD >" "netdb" "_Clientes" "

file name generated by mysqldump: "_Clientes.txt."
CTL file:
load data
INFILE ' data / CLIENTES_1.txt ".
"str"< EORD >"
in the CLIENTES_1 table

Is this a bug, or are we supposed to manually fix the scripts for these cases?

Thank you

Edited by: user12099785 11/10/2011 06:11
Currently, you have to fix manually because there was no bug recorded for this question. I have now filed the bug and it will be if all goes well fixed in one of the next versions to come.

Choose between MySQL and Oracle - problem with MySQL text columns?
Hello.

New to this forum and Oracle please go easy on me.

I'm selecting data in a MySQL database.

This SQL works very well: -.
Select 'Device_Label' Device"@ed_link «»
where "Device_ID" = 6665;
Here, the MySQL Device_Label column is of type varchar (255).

This SQL fails with the error - ORA-00904: "Device_Tag": invalid identifier
Select 'Device_Tag' Device"@ed_link «»
where "Device_ID" = 6665;
Here, the MySQL Device_Tag column is of type text.
Column Device_Tag certainly exists and is populated.

Is the problem related to the MySQL type text column, and is there a solution?

Thank you.
Hello
The ora-997 because of the entry door is not a restriction of the Oracle. You cannot use a table defined as a long in the create table... as select statement..., you would see the problem even if it was a copy of Oracle for Oracle.
If one of the columns of MySQL are translated as a long in Oracle you will hit this problem.
The bypass alone is to avoid columns long or you can try to create a view in MySQL by using the cast function, which converts the columns that translate to long something and then use it in the create statement.

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.
DB objects migrate successfully except stored procedures.
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.

The documentation includes details of the difference between MySQL and Oracle stored procedures-

I know it is posible to create a dblink Oracle to MySQL, but the question is, is posible to create a link between MySQL to ORACLE Db?

I hope that this question as soon as posible.

And why do you think that the answer would come ASAP?

As far as I KNOW, mysql doesn't a link db support.

Why is conversion of procedures & functions due to lack of MySQL to Oracle?
Hi all

I'm trying to migrate a database from MySQL to Oracle using the Migration Workbench data in SQL Developer 1.5.4.
I ran both the quick Migration Wizard and the Manual Migration process as described in the documentation.

I get through the process very well, even if not everything is successfully migrated. Namely, stored procedures and functions of the database of third parties are not correctly migrated.
The following text is listed in the Migration log for each of the stored procedures and functions:

* "Limitation of the translation"procedure_audit requires a translation of the manual"met on the column of the stored procedure fse.procedure_audit line 0-0."

If I look at the 'converted' model the procedure has been created and is set to NULL. The procedure of 'captured the model' original is commented out in the body of the procedure in the "convert" template Does anyone have any ideas as to why it's a failure? And how do I fix it?

In addition, there seems to be a problem with the conversion of the index, particularly those that are 'MAJOR' indexes in MySQL not appear in models 'captured' or 'converted '.

In addition, the migration log provides the following:

* "Index 'customer_customer_id' on the 'customer' table ' has been ignored, because it is a duplicate of a constraint" * "

Looking at the index in the original third party database, it does appear that an index on that column on the respective table. The ides why this happens?

Here, any help would be immensely appreciated.

Thank you
Amedeo.

Hi all
I have Oracle 10.2.0.5 server and MySQL 5.3 on windows environment. all are 64-bit.
I want to connect to MySQL. I do the following
Configure Listner.ora

create file initodbc.ora in the folder hs

HS_FDS_CONNECT_INFO = mysql

HS_FDS_TRACE_LEVEL = OFF

Restart the listner

then try to select from a table inside the MySQL database

SQL > select * from appeal@mysql;

Select * from appeal@mysql

Cannot retrieve the text of the message NETWORK/NCR 65535

ORA-02063: preceding 2 lines of MYSQL

How could I solve this problem?
Thank you.

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

UNIX_TIMESTAMP and FROM_UNIXTIME from MySQL to ORACLE functions

Hi all
I'm migrating some functions and stored procedures in MySQL to ORACLE, and I the next instruction
Set valuedat = FROM_UNIXTIME (valor + UNIX_TIMESTAMP ('2000-1-01 00:00:00 '));
Since MySQL.
Look, I found that:
UNIX_TIMESTAMP ('2000-1-01 00:00:00 ')
can be equivalent to the following query:
SELECT (to_date (January 1, 2000 "," MON-DD-YYYY')-to_date('01-jan-1970','DD-MON-YYYY')) * (86400) as dt FROM dual;
but testing the numbers is not the same
Please can someone help me!
Specifically, I need to know how to build the equivalent in oracle for FROM_UNIXTIME and UNIX_TIMESTAMP functions
Thank you and best regards!
CRGM

Hello

These are functions that I built to solve the original requirement, thanks for all your comments.
