How to handle DATE type problems in migrating from mysql to oracle.?

Hi,
I'm migrating only the data from mysql to oracle with the help of sql loader.But with this type i cannot able to insert the date values from mysql to oracle.In mysql i have defined date as "DATETIME" type and in oracle it is in TimeStamp.Whenever i'm inserting the values thru CTL file ,i'm getting an error invalid date format entered.How to solve this problem?
Thanks in Advance
JAI

you need to supply a mask to the timestamp entry. see http://download-west.oracle.com/docs/cd/B19306_01/server.102/b14215/ldr_field_list.htm#i1006714 for details on datatypes within the ctl file

"Default " problem while migrating from mysql to oracle.

I'm migrating from mysql3.23 to oracle9i via the OMWB tool.While migrating i'm getting an error message "Failed to create default for the table <table>:ora00907 missing right parenthesis".This error is due to the difference in the syntax used for the keyword "default" in mysql and oracle.In mysql we have to give after the Not Null option whereas in oracle we have to give before Not Null.
The problem is i'm migrating via the OWMB tool.Is is possible to handle this error with the help of tool itself.
Thanks
Jai.M

Jai, I'm having Frank have a look at this for you to see if we can replicate it ans help solve this issue for you. are there any issues logged on the mysql site regarding saving blobs as file?
thanks

DB Migration from MYSQL to ORACLE Using Offline Capture

Hi
Am doing a database migration from MySQL to Oracle using SQL Developer (version 2.1.1.64). So far, I've successfully captured the MySQL database and converted it to the Oracle Model. However, when generating offline scripts to create the converted model schema into Oracle DDL scripts it managed to generate SQL to create: 1) User 2) Sequences 3) Tables 4) Triggers and 5) constraints.
It has created the SQL to add the primary key constraints and index constraints. Although it did the foreign key constraints in the SQL, the foreign key constraints seems to have missed the cascading options for the foreign key constraint. I.e. theres no reference of whether the foreign key constraint will restrict on delete or cascade etc.
We have a foreign keys in the MySql database that have different cascading options and these have not being ported over into the migration SQL. Therefore, all the foreign keys generated in the SQL by default are cascade to restrict on delete.
Does 'Generate Oracle DDL' not take into account a foreign key's on delete cascading option?
Any help or information would be greatly appreciated.
Thanks

Hello,
that reminded me for the following thread:
Migration Microsoft SQL Sever 2005 to Oracle 11g cascade on delete problem
That is a similar issue, isn't it?
I opened a bug for that, and it will be fixed in SQL Developer 3.1 (not in any 3.0 Early Adopter version). If you hit the same issue, there is no other way then using the workaround as used in the mentioned thread.

Wolfgang

Problem while migrating from Sybase to Oracle using Quick Migrate

Hi,
For SQL Developer version 2.1, while migrating from sybase to oracle, Using Quick migrate, during data move step, for the rows having ''(Blank) values in TEXT data type in SYBASE, which is convertd to CLOB in Oracle, the migration for that table terminates at that row.
However, NULL values in Sybase TEXT data type are successfully inserted in Oracle CLOB.
How can we overcome this?

reproduced and see exception in console, bug logged.

Problems while migrating from mySql DB to oracle DB

Hi All,
I'm using sql developer tool to migrate from MySql DB to oracle DB. I followed the below steps.
1) I've created oracle and mysql connections successfully.
2) I've captured Mysql data and I'm able to see the captured model in ' Captured Models ' window. After that right clicked on the captured model and selected ' Set Data Mapping'. Selected ' apply ' button without changing anything. After that I've right clicked on the captured model and selected ' Convert to Oracle Model ' . It has shown the converting process. After some time it has shown conversion completed successfully.
But converted model is not visible in ' Converted Models ' window.
Can anyone kindly assist on how to migrate from MySql Db to Oracle DB?
Thanks,
Saty.

Hi,
We did mysql to oracle migration some time back and played with workbench tool and many other softwares available.
However our experience was not so good with these tools, each tool had its own limitation and was not able to migrate 100% data. Even the speed of migration was too slow which would have violated our production SLAs.
So after spending a month with these tools we finally decided to create our own scripts for data migration. We used tools like TOAD and SQL Yok to create the DDL for the tables and other DB objects.
For the data migration we downloaded the mysql data in flat files and used sql loader to upload the same data in oracle. Even if this was a time consuming activity but this resulted in 100% data migration with no record getting failed and the time taken for this activity was around 6 Hrs in comparison to time of 24-28 Hrs that the workbench tool took.

Migrating from MySQL to Oracle 11g

can u tell me the steps to migrating database from MySQL to Oracle using SQL Developer?
I have installed Oracle 11g(11.1.0.6.0) in server and SQl Developer in my local system.

it took one and half day but didn't work at last...
is there any pre tasks that i need to do before migrating to oracle from MySQL?
and also when i export the MySQL data to Oracle using SQL Developer,it is giving data type mismatch errors like (date, boolean etc...).
please give a reply what i need to do and any refferences also very much appreciated.

hi Turloch ,
I followed the steps mentioned above.
When I right click my MySQL server db Connection and click "Capture MySQL server", it just shows a dialog with "Close" enabled.

the same error is coming no of times.
Kindly help me in this regard.

Out of memory error in migrating from mysql to oracle

Hi,
I'm trying migrate from mysql to oracle9i. The hardware and software requirements are matching or even much higher than mentioned in the documentation. I have installed OMWB is properly(hope so). When I try to migrate the desired database from mysql to oracle, the repository, the Oracle model are created successfully. But while migrating data, say for around 35000 rows insertion everything works pretty fine. But after sometime, the migration stops and no error or anything appears in the screen.And in the Errorlog I get "OutOfMemoryError".
I tried to migrate single table also. But I still get this problem after sometime. The tables may contain from 10 - 130000 rows...
I even tried to change the %JRE..% memory value to 64M or 128M in the omwb.bat file and the O/s is Microsoft Windows XP, RAM 256MB.
Any help is much appreciated.
Thanks in advance.

Hi Viji,
did the message in the error.log provide any extra information? For example, was the OutOfMemory error prefixed with a string
like "cannot create new native thread" ? My suggestion to workaround the problem would have been to increase the JVM heap size to 128
but this appears to have been unsuccessful for you. Can you send a mail to the Migration Workbench support services
([email protected]) explaining the problem, and attach the full error.log file please ? (please also copy me on the mail).
In the meantime, you can workaround this by migrating the schema only (there is a switch on step 3 of the migration wizard asking:
"Do you want to migrate the table data to Oracle?" - just select the "No" option). When the schema has migrated, you can then use the
offline data loading facility to migrate the data. This uses data extraction scripts and SDQL*Loader to migrate the data to the target
Oracle database.You can learn more about the offline data loading facility from the plugins referenceguide (from the Help menu in
the Migration Workbench).
I hope this helps,
Tom.

How to resolve the encoding problem while migration from informix9.4

When I migrate the informix9.4 database, there occur a error while migrate the data from informix to oracle.
Because the source tables has a column which type is "vchar", the some row's data length more the 4000, so migration workbench convert this column type from "vchar" to "clob" automaticly. But when the worbench has created the oracle model, and then migrate the data, there occured this error:
java.io.UnsupportedEncodingException: ISO2022CN_GB
java.sql.SQLException: index miss IN or OUT param:: 9
+     at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:125)+

+     at oracle.mtg.migrationServer.LoadTableData.run(LoadTableData.java:326)+
+     at oracle.mtg.migration.WorkerThread.run(Worker.java:268)+
The encode in the source informix database is "zh_CN.gbk", and the encode in the destination database is "zh_CN.gbk", why this prompt the convert error?
Another information is that excluding this table, other tables can migrated success.
So, I guess this problem must has association with the type conversation which from "vchar" to "clob", can anyone help me with this, Thanks.

Hello,
well, the limit of 4000 is clear. From the Oracle® Migration Workbench Reference Guide for Informix Dynamic Server Migrations:
VARCHAR(m,r)
The Informix Dynamic Server VARCHAR data type stores varying length single-byte and multibyte character strings of letters, numbers. and symbols. The maximum size of this column is m, that can range from 1 to 255. The minimum reserved space is r. This is optional and defaults to 0 if not specified. The minimum reserved space can range from 0 to 255.
The comparable Oracle data type is VARCHAR2(n) that also stores variable-length character strings. An Oracle VARCHAR2(n), however, can have a maximum string length of between 1 and 4000 specified for n.
Specifying a minimum reserved space is useful if the data in a row is initially small but is expected to grow at a later date. If this is the case then, when migrating Informix Dynamic Server tables that contain VARCHAR columns consider increasing the PCTFREE value in the storage clause for these tables in the Oracle database. If this column is used in an index, then the PCTFREE values for the corresponding index storage should also be considered. For indexes based on VARCHAR columns, Informix Dynamic Server allocates the maximum storage.
So it is not surprising that the workbench is converting a VARCHAR with a length of more than 4000 to a CLOB.
But that does not explain the encoding exception. This might be a problem of the Informix JDBC driver.
Is the Informix JDBC Driver Programmer's Guide helpful for you: http://publibfi.boulder.ibm.com/epubs/pdf/6435.pdf
Can you reproduce the problem with a Java program against your Informix database using your Informix JDBC driver?
Which version of Informix JDBC driver are you using?
Best regards
Wolfgang

Migrating from MySQL to Oracle 11gR2 containing accented characters

Hello Gurus,
I am going to migrate a MySQL database that contains accented characters. The collation of the tables holding these data is utf8_unicode_ci.
I used SQLDeveloper to generate data migration scripts. After a test migration run, the web pages displays "?" instead of the accented character.
I am currently tracing where the problem is.
From what I have read, mysqldump uses utf8 as the default character set, so I assume the accented characters in <tablename>.txt files are in tact.
Could the problem be on sqlldr? Has anyone come across this problem?
I really would appreciate any help.
Thanks

Migrating from MySql to Oracle

Hi,
I have installed latest version of SQL Developer with new Extensions (added mysql-connector-java-3.1.14-bin.jar under third-party database extension tab) , also installed latest updates from Help Menu. I have created a database in Mysql and now migrating it to Oracle, while I click on Capture MySQL / Quick MySql migrate... i get error "Error ocurred during capture: ORA-01400: cannot insert NULL into ("ASHISH"."MD_PROJECTS"."ID") ".
Thanks,
Ashish Sohane.
OracleDirect.

I am having the same problem. I have deleted and recreated the repository many times. I'm getting:
"SQL Error on Script Execution. Try deleting repository before Creating Repository."
then
"The Repository installtaion has failed. Please check the user you are registering and make sure that objects of the same name do not already exist"
I have closed the connection and reopened, closed SQL Developer and reopened. When I expand Tables, there are NO md_ tables. So it seems the repository deletion is working. But when I try to recreate it, oracle somehow thinks the repository I deleted is still there.... even tho it doesn't show it in the ui.
Although this thread began w/ someone converting from MySQL i think that is probably irrelevant. We are getting the same errors with the oracle repository. I am converting from MSAccess2003 using SqlDeveloper 1.2.1. I have successfully created the XML and SQL exports from MSAccess using SqlDeveloper\Migration\MicrosoftAccess Exporter\2003

Problems with migrating from access to oracle

OMWB has a few problems with upper and lower case letters, when i try to modify my old access DB OMWB cant find the new table in Oracle:
(3011 The Microsoft Jet database engine could not find the object <name>. Make sure the object exists and that you spell its name and the path name correctly. )
the problem is that it searching for AP_BILD.A990BILDER but the correct name is AP_BILD.a990Bilder
when i recreate the table as AP_BILD.A990BILDER it worked.
but i cant do that for almost 400 tables!
any suggestion how to fix this?
also have a problem when creating the trigger:
OMWB puts the tablename into 2 double quotation marks each side (""name"") and of course it tells me something of a tablenamelength of NULL and it doesnt work
working with release 9.2.0.1.0 of OMWB

update: if i try to link the table from access directly it also cant find the table, but can find other tables (the others are in upper case).
could it be a problem with the odbc driver? does it automatically look for upper case names?
anyone know how to fix this?
thanks in advance

Hi Vladimir,
I send you a message from the Migration Workbench team that solved my problem. I hope this will resolve yours too.
Bye,
Pierfrancesco
Hi Pierfrancesco
MySQL 3.22, 3.23 Requirements
In order to migrate from MySQL to Oracle, you must install the MM MySQL JDBC
driver release 1.2a on the same system as the Migration Workbench. You can
obtain this by downloading the MM MySQL JDBC driver from the WorldServer Web
site at:
http://www.worldserver.com/mm.mysql
Copy and unzip the mm.mysql.jdbc-1.2a.zip file to your
%ORACLE_HOME%\Omwb\drivers directory. This automatically creates a new
directory called
mm.mysql.jdbc-1.2a within the drivers directory.
Can you please verify that you have this driver extracted to the above
specified directory. Another check you can do is see whether all the files in
the zip
have extracted.
Please refer to the Release notes which you have access to by selection the Help
drop down menu in the Workbench.
I hope this helps
Best regards

is anyone had same problem like me?
how to fixed it(if passable)?
and, how to change data type?
thanks.

Hi Sruthi,
all you need to do on this is open the report go to the parameters, select the parameter that you wish to change and click "Edit". This will allow you to change thefield to a date rather than a date time.
