Sql developer migration time

Hi,
One month back,I did migration of mysql to oracle using sql developer.It took around 2-3 hours to finish.But when I am again migrating the same database,the estimated time is around 150 hours.There were no big changes in the database in one month.Its taking a very long time to capture constraints.
Scenario is as follows
test(MySQL) --> test(Oracle schema) took 2-3 hours
test1(MySQL) --> hms(Oracle schema) ongoing from last 6 hours and expected finish time around 150 hoursPlease advise
Thanx

Hi,
I am unable to replicate the issues here.
I created a 500 table MySQL database with constraints on each table and it captured online quickly.
My only guess is there is some additional load on one of your machines which maybe slowing down the process?
As an alternative path, you could attempt the offline capture of your database.
* Tools > Migration > Create Database Capture Script
* Choose MySQL 5 windows or whatever suits
* Run these scripts on your MySQL machine (with MySQL client) to dump out the databases metadata
* Move all the files to your SQL Developer machine
* Capture Offline the mysql5.ocp
Sorry I couldn't have been more help

Dermot.

Unable Update SQL Developer with Times Ten in-Memory DB Extension 1.2.1.1.0

SQL Developer 1.2.1 Build MAIN 32.13 (Windows XP)
We can't Update SQL Developer with Times Ten in-Memory DB Extension 1.2.1.1.0 :-((
We did the same actions as described in tutorial
http://www.oracle.com/technology/products/timesten/viewlets/tt703_sqldev_install_ext_viewlet_swf.html
In addition to tutorial we have "Log In" window
"To download Oracle Times Ten in-Memory Database Extension
you must enter your Oracle Web Account user name and password"
This window was not displayed in tutorial...
We try to use three our OTN accounts and the result
was the same - we was asked with "User name" and "Password"
again, again, again and again,,, :-(
Is it a bug or a feature?
Mayby we didn't understand something or did something wrong?

Hi Simon,
I found cause of update failure! It was the HTTP proxy setting.
I turned off "Use HTTP proxy server" checkbox in SQL Developer -> Tools -> Preferences -> Web Browser and Proxy.
After this action SQL Developer was successfully updated with Times Ten Extension.

SQL Developer Migration Workbench - Migrate only one Database?

Hallo!
We want to use Oracle SQL Developer Migration Workbench Early Adopter for migrate some Databases from SQL 2000 to Oracle 10g R2 (on XP SP2 SQL Developer 1.1.2.25.79).
The first Database we can migrate to Oracle. The Loader files in OMW are better!
On next day the menu capture schema was not reachable ( gray) . What can we do?
Thanks.
Michael

Michael,
<p>Have you seen the Getting Started guide? It looks like you have just started and not taken the next step. Once you are connected to your repository, select the SQL Server connection and use the "Capture..." option in the context menu for that connection.
<p>Regards
Sue

Oracle SQL Developer vs Oracle SQL Developer Migration Workbench

Gurus,
Can anybody let me know what's the difference between Oracle SQL Developer vs Oracle SQL Developer Migration Workbench tools.
I am in the process of Migrating MS-Access Application to APEX. So the example says me to use Oracle SQL Developer Migration Workbench. Is this part of Oracle SQL Developer? If yes, I know SQL Developer is free.
If not is Oracle SQL Developer Migration Workbench if free?
Thanks and Regards

Thank Oracle ;)
(well, it's the least they can do after you paid big $$$ for the database)

How to convert CLOB to BLOB with SQL Developer migration wizard?

Hi,
According to our requirement, we need to only migrate data from SQL Server 2008 to Oracle 11. I use the SQL Developer 3.0.04 migration wizard to do it.
I do migration from SQL Server (database name: SCDS41P2) to Oracle (User name: HCDS41P2).
My migration steps are as below: (I need to modify the target schema, so I add the steps 2) and step 3) )
1) Do migration by SQL Developer migration wizard;
2) Remove the Converted Database Objects node from migration project;
3) Re-do convert by SQL Developer migration wizard (contains changing the target schema);
When do step 1), the DBO_SCDS41P2 user is created automatically. CLOBTOBLOB_SQLDEVELOPER procedure is also created in this user.
I continued to run step 2) and step 3) with online mode. And find the table data which contains BLOB column can be moved into the target table. But from the Logging Page, I can't see the other detailed error info, so that I can't check which tables don't move data successfully.
Could you please tell me where the detail log file (e.g. contains every table's migration status) is if I use the online mode?
Additional, If I use offline mode to do step 3), I found the CLOB data can't be converted into BLOB automatically. Because in the load script (that is oracle_ctl.bat), only copy the source data to the CLOB column. After copy, it don't deal with the converting from CLOB to BLOB.
So could you please tell me how to convert CLOB to BLOB with offline mode?
Thanks so much.

Hi,
For your first question about logging - after the migration there will be an entry in the right hand panel for the migration project. If you open this there are various fields that give information about the status of each part of the migration. Does this give you the information you need ?
For the second problem about offline moving blob data have a look at the SQL*Developer documentation -
Oracle® SQL Developer User’s Guide Release 3.0
in the section -
2.2.8.1.4 Populating the Destination Database Using the Data Files
which describes the problem and how to get round it.

Mike

Did you perhaps do a custom install? The DB software includes a version of sql developer and, by default, installs it in the sqldeveloper folder of the DB_HOME. Does that folder have sql developer in it?
I suggest that you NOT use the version of sql developer that ships with the database. That version will NOT be the current version.
Download the current version of SQL Developer, unzip it into a new folder and create a desktop icon for it.
http://www.oracle.com/technetwork/developer-tools/sql-developer/downloads/index.html
The current version includes many, many bug fixes from that earlier DB version and you will have far fewer probems with it.

Error in Migration Repository using Sql*Developer Migration Workbench

To migrate a MS access mdb database to Oracle using Sql*Developer Migration Workbench, I try to create first the the Migration Repository in SQL*Developer.
The repository is created, but under PACKAGES I could see that package MD_META has been compiled with errors.
PACKAGE BODY AO_PERSONAL.MD_META@DMCAPX (AO_PERSONAL):
Error(27,2): PL/SQL: SQL Statement ignored
Error(30,23): PL/SQL: ORA-00904: : ungültiger Bezeichner
Well, when I ignore this and continue with the next step of the migration process "Capture Microsoft Access Exported XML file" to create the Captured Model, I get the following error message:
ORA-04063: package body "AO_PERSONAL.MD_META" enthält Fehler ORA-06508: PL/SQL: aufgerufene Programmeinheit : "AO_PERSONAL.MD_META" konnte nicht gefunden werden ORA-06512: in "AO_PERSONAL.MD_PROJECTS_TRG", Zeile 3 ORA-04088: Fehler bei der Ausführung von Trigger 'AO_PERSONAL.MD_PROJECTS_TRG'
Target database RDBMS is Oracle Database 10g Enterprise Edition Release 10.2.0.3.0. So the proposal of note 427916.1 to create the Repository in a 10.2 RDBMS does not solve the problem.
I even tried to use the Quick Migrate feature in SQL*Developer, but got the same error message.

"inserted value too large for column"
Is there a LOGON trigger on the database or user ?
I'd be surprised at SQL Developer trying to insert data into anything on connect.
I'd suspect code being executed by the database, maybe using a MODULE or PROGRAM from v$session or USERENV / SYS_CONTEXT.

Migration Verifier Tool for SQL Developer Migrations?

Hi all,
The old Migration Workbench has an optional add on verification tool to verify migrations to Oracle.
I am looking for a similar migration verifier tool for the SQL Developer migration process.
Does one currently exist for SQL Developer migration tools?
Regards,
Ben Prusinski

Hi Ben,
The old migration verifier seems to be at:
http://www.oracle.com/technology/tech/migration//dmv/index.html
Sue Harper (Product Manager) would be the person to comment further probably through SQLDeveloper statement of direction:
http://www.oracle.com/technology/products/database/sql_developer/files/sqldeveloperstatementofdirection.htm
I do not see anything there.
There is a tools->database diff wizard which I have not looked into in detail and I doubt that applies for migrations.

SQL DEVELOPER MIGRATION

I have downloaded Oracle SQL Developer 1.1 Patch 3 (1.1.3.27.66).
Its says Migration from third party database can be done using this software.
However the Migration menu or the Associate Migration Repository is not available.
Is this the right version of the software or should i use any other software.
(I am trying to Migration a SQL server database to ORACLE)
Thanks
Roop

Roop,
I see that you have successfully completed what you wanted to do. For future reference, please note that the SQL Developer Migration Workbench is now production.
There is a lot of supporting collateral for this new product on the SQL Developer Migration Workbench pages:

DB2 to Oracle conversion using SQL Developer Migration Wizard - different schemas

I am performing a conversion between DB2 to Oracle 11 XE, using the SQL Developer Migration Wizard. Specifically I am trying to migrate the DB2User schema over to Oracle.
Using the migration wizard, when I pick the Oracle target connection to be the same schema ( DB2User schema ) the migration is successful and all data is converted.
However if I pick a different Oracle target connection ( say OracleUser ) , I run into issues.
Firstly , the table schema is not created. When I check the project output directory, the .out file has the following errors:
   CREATE USER DB2User IDENTIFIED BY DB2User DEFAULT TABLESPACE USERS TEMPORARY TABLESPACE TEMP
        SQL Error: ORA-01031: insufficient privileges
        01031. 00000 - "insufficient privileges"
    connect DB2User/DB2User
    Error report:
    Connection Failed
    Commit
    Connection created by CONNECT script command disconnected
I worked around this by manually executing the .sql in the project output directory using the OracleUser id in the new DB.
Then I continue with the migration wizard and perform the Move Data step.
Now - the message appears as succuessful, however, when I review the Migrationlog.xml file, i see errors as follows:
<level>SEVERE</level>
<class>oracle.dbtools.migration.workbench.core.logging.MigrationLogUtil</class>
<message>Failed to disable constraints: Data Move</message>
<key>DataMove.DISABLE_CONSTRAINTS_FAILED</key>
<catalog><null></catalog>
<param>Data Move</param>
<param>oracle.dbtools.migration.workbench.core.logging.LogInfo@753f827a</param>
<exception>
    <message>java.sql.SQLSyntaxErrorException: ORA-00942: table or view does not exist</message>
<level>WARNING</level>
<class>oracle.dbtools.migration.datamove.online.TriggerHandler</class>
<message>ORA-01031: insufficient privileges
</message>
I think what is happening is that the wizard is attempting to perform the 'move data' process using the DB2User id.
How do I tell the wizard that the target schema is different than my source schema.
My requirement is that I need to be able to migrate the DB2User schema to different schemas in the same Oracle database
( since we will have multiple test environments under the same database ) .
Thanks in advance .
K.

Perhaps the following from the SQL Developer documentation is helpful for you:
Command-Line Interface for Migration
As an alternative to using the SQL Developer graphical interface for migration operations, you can use the migration batch file (Windows) or shell script (Linux) on the operating system command line. These files are located in the sqldeveloper\sqldeveloper\bin folder or sqldeveloper/sqldeveloper/bin directory under the location where you installed SQL Developer.
migration.bat or migration.sh accepts these commands: capture, convert, datamove, delcaptured, delconn, delconverted, driver, generate, guide, help, idmap, info, init, lscaptured, lsconn, lsconverted, mkconn, qm, runsql, and scan. For information about the syntax and options, start by running migration without any parameters at the system command prompt. For example:
C:\Program Files\sqldeveloper\sqldeveloper\bin>migration
You can use the -help option for information about one or more actions. For the most detailed information, including some examples, use the -help=guide option. For example:
C:\Program Files\sqldeveloper\sqldeveloper\bin>migration -help=guide

Hello,
I get the same error after updating through Help->Check for Updates. I am at version 1.1.2.25 and the update does not change the version number of Oracle SQL Developer (Help->About), it remains at 1.1.2.25 (although if I look in extensions tab, it says: oracle.sqldeveloper 1.1.3.27.66 Loaded, possible bug in displaying version number?). These are the updates applied:
Upgraded Extensions
Oracle Microsoft Access Browser version 1.1.3.27.66
Oracle SQL Developer - Snippet version 10.1.3.27.66
Oracle SQL Developer version 1.1.3.27.66
Oracle SQL Developer - Reports version 10.1.3.27.66
Oracle SQL Server Browser version 1.1.3.27.66
Oracle MySQL Browser version 1.1.3.27.66
Oracle SQL Developer - Worksheet version 10.1.3.27.66
Oracle SQL Developer - Extras version 1.1.3.27.66
Oracle SQL Developer - SearchBar version 10.1.3.27.66
Oracle SQL Developer - Object Viewer version 10.1.3.27.66
I ran the update several times and was able to reproduce the error under a specific condition. If I am connected to a database at the time of the update I get the error. If I am not conneceted at the time of the update I do not get the error.
As stated, by Donal, sql developer seems to get over the problem after restarting itself twice.

Issue with migration DB from SQL Server 2005 to Oracle 11.2 using SQL Developer Migration workbench

Hi,
We face an issue while migrating an SQL Server 2005 DB to Oracle 11.2. It fails during the process. I hope someone on the forum has seen this before and can give us some advice.
I use the latest version of SQL Developer with JRE included (3.2.20.09). The JDBC driver to connect to SQL Server 2005 is 1.2.0
Here are the steps we take in the Migration Workbench wizard:
I made an online extract of the SQL Server database.
Using the workbench in SQL Developer I created a migration repository in schema PDM_MIGRATION.
Next I start the migration, it captures the tables fine, but immediately after the start of the conversion I get a failed message without further explanations.
This is the content of the error xml:

Does anybody know what this error means and what steps we should take to continue the migration?
I see the PDM_MIGRATION.MIGR_FILTER is a type.
Many thanks in advance,
Kris

Hi Wolfgang,
Thanks for your reply.
This is how the type MIGR_FILTER looks like:
create or replace
TYPE MIGR_FILTER IS OBJECT (
FILTER_TYPE INTEGER, -- Filter Types are 0-> ALL, 1->NAMELIST, 2->WHERE CLAUSE, 3->OBJECTID LIST
OBJTYPE VARCHAR2(40),
OBJECTIDS OBJECTIDLIST,
NAMES NAMELIST,
WHERECLAUSE VARCHAR2(1000));
I think the repository user has the correct privileges. This is the overview of privileges it has:
SQL> select * from dba_sys_privs where GRANTEE in ('PDM_MIGRATION') order by GRANTEE;
GRANTEE PRIVILEGE ADM
PDM_MIGRATION ALTER SESSION NO
PDM_MIGRATION CREATE CLUSTER NO
PDM_MIGRATION CREATE DATABASE LINK NO
PDM_MIGRATION CREATE PROCEDURE NO
PDM_MIGRATION CREATE SEQUENCE NO
PDM_MIGRATION CREATE SESSION NO
PDM_MIGRATION CREATE SYNONYM NO
PDM_MIGRATION CREATE TABLE NO
PDM_MIGRATION CREATE TRIGGER NO
PDM_MIGRATION CREATE VIEW NO
PDM_MIGRATION UNLIMITED TABLESPACE NO
SQL> select * from dba_role_privs where GRANTEE in ('PDM_MIGRATION') order by GRANTEE;
GRANTEE GRANTED_ROLE ADM DEF

SQL Developer Migrate mySQL to 11g gets ORA-00972 due to 30 char name limit

I am running MySQL version 5.5.30 server, SQL Developer 3.0.04 Build MAIN-04.34, and Oracle Enterprise Server 11.2.0.1.0, and using Migrate option to move both data dictionary and data from mysql to Oracle
Most of the steps worked fine using OnLine option: used Capture just fine to generate the repositiory, and Convert generated DDL script just fine in the SQL Developer file folder.
It failed to create users due to privs, but I created them manually: emulation user and also the MYSQL data schema user, after which I took the generated DDL, connected to my Oracle data schema user, and ran the DDL to basically create all the objects. And found out that over 50 tables / column names from MYSQL are longer then 30 char, and thus the generated DDL fails to create objects..
Question - I can manually replace the names with shorter 30 char names, but if I do, my data migration step will not work.
i cannot find references to 'name too long' problem anywhere is SQL Server documentation..
here is the Oracle error example:
Error report:
SQL Error: ORA-00972: identifier is too long
00972. 00000 - "identifier is too long"
*Cause: An identifier with more than 30 characters was specified.
*Action: Specify at most 30 characters.
Creating Primary Key Constraint PRIMARY_1 on table bank_account ...

Hello,
have you tried the offline migration option? Then you can probably modify also the ctl file for the SQL*Loader to reflect your changes in the DDL script. I didn't yet try it out, it was just an idea that came to my mind.

SQL Developer Migration Workbench - Data Type Mappings

Hi,
Using SQL Developer 1.1.3.2766 to migrate a MySQL 4.1.22 database.
How do I change a system defined data type mapping? I would like to map "text" data type to "varchar2". This is something I could do in OMWB.
I can create a new rule but cannot delete the system defined "text" rule.
thanks,
Greg

Greg,
You cannot delete the system default rules, but if you create your own, these will take preference during the convert phase. Is this not the case?

SQL Developer migration tool

Does anyone have any experience migrating just one schema from MySQL to Oracle?
I've specified my database that I want the migration tool to use when I do the migration, but it goes ahead and tries to grab every single function, procedure, table for every single user in the database.
I'm basically trying to migrate a customers' mysql dataset to our oracle db.
Any thoughts?
Thanks in advance all!
---Patrick

Patrick,
did you already read the Oracle® Database SQL Developer Supplementary Information for MySQL Migrations manual, available at:
http://download.oracle.com/docs/cd/E12151_01/doc.150/e12155/toc.htm
The chapter 2.2 is dealing with schema migrations. Perhaps that is useful for you. If there is going something wrong for you and different as described in that manual then please let me know more details.
Best regards
Wolfgang
