Is it possible to migrate a mediumblob from mysql to oracle.?

I'm having a medium blob type in mysql which contains an image name say "one.gif".But after executing the dump_extract.bat file and viewing the data in the txt file ,One.gif is appened with lot of special chracters.Due to this i'm getting" the column exceeds maximum length" error while executing thru the SQL_Loader.
Thanks in Advance,
Jai

Yes. Locate the file named Domain.sites that is located in your Home/Library/Application Support/iWeb folder and copy it to the same folder on the new drive. Launch iWeb and it will locate and open the file.
If there is not iWeb folder in the Applicaitons Support folder create one.
NOTE 1: In Lion and Mountain Lion the Home/Library folder is now invisible. To make it permanently visible enter the following in the Terminal application window: chflags nohidden ~/Library and press the Return key - 10.7: Un-hide the User Library folder.
Note 2: iWeb 08 is not compatible with Mt. Lion and will experiencing problems publishing to a folder and crashing. iWeb 3 (09) is compatible with Mt. Lion.

Problem in migrating huge data from mysql to oracle using OMWB.

I'm using OMWB to migrate my mysql db to oracle db.Mysql db contains some 43 tables and all of them were copied to oracle db except a table "as_db" which contains some 503 mb of data.The table contains 3 columns and two of them were integer type and one is of medium blob.While migrating i'm not getting any error.After migrating i opened the table in the oracle.The table alone created but there were no datas.But all other table contains data.
Then i generated the ctl file usiing SQL*loader for that particular table alone and tried to execute but it also fails by giving the Column size exceeds for blob.
How i handle this issue?
Thanks in Advance,
Jai.M

Looks like you may have to save you blobs out as files and load them individually thru the sqlldr process. I know this has normally been done thru raw to blob
What way is your blob data being saved out in the extract data file.

Best practice for loading from mysql into oracle?

Hi!
We're planning migrating our software from mysql to oracle. Therefore we need a migration path for moving the customer's data from mysql to oracle. The installation and the data migration/transfer have to run onto different customer's enviroments. So migration ways like installing the oracle gateway and connect for example via ODBC to mysql are no option because the installation process gets more complicated... Also the installation with preconfigured oracle database has to fit on a 4,6 GB dvd...
I would prefer the following:
- spool mysql table data into flat files
- create oracle external tables on the flat files
- load data with insert into from external tables
Are there other "easy" ways of doing migrations or what do you think about the prefered way above?
Thanks
Markus

Hi!
Didn't anyone have this requirement for migrations? I have tested with the mysql select into file clause. Seems to work for simple data types - we're now testing with blobs...

Is it possible to migrate the app from latest version to older version

Hi all,
I have a adf application in jdeveloper 11.1.1.4.0.Due to some issues i have to do it in jdeveloper 11g release 2 (11.1.1.2.0).Is it possible to migrate the application from latest version to older version of jdev.
Thanks.

It's not officially supported, but you can try a couple of things - first open the application in the old version and see if it works.
If it doesn't you can try creating a new application in the old version and then use the create project from existing source option to map to your existing code.
This all of course assumes that you didn't use features in the new version that are not available in the old version.

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.
I connected to MySQL and Oracle in SQL Developer and tried to MIgrate everything in MySQL to Oracle using Quick Migrate option.
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.

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 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

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.

Translating SQL from MYSQL to ORACLE with more than one outer join.

I will translate the following sqlquery from MYSQL to ORACLE:
SELECT ticket.ticket_no,ticket.ticket_dato,ticket.ticket_subject,ticket.customer_id,customer_name,ticket.ticket_own_read, ticket.department_id, department.department_name, priority_name, tickstat_name, tickettype_name
FROM customer, ticket left join department
on ticket.department_id = department.department_id left join priority on ticket.priority_id = priority.priority_id
left join ticketstatus on ticket.tickstat_id = ticketstatus.tickstat_id
left join tickettype on ticket.tickettype_id = tickettype.tickettype_id
where ticket.customer_id = customer.customer_id and customer.owner_id =
#session.owner_id#
I have tried in ORACLE with:
SELECT ticket.ticket_no,ticket.ticket_dato,ticket.ticket_subject,ticket.customer_id,customer_name,ticket.ticket_own_read, ticket.department_id, department.department_name, priority_name, tickstat_name, tickettype_name
FROM customer, ticket ,department, priority, ticketstatus, tickettype
where
ticket.department_id(+) = department.department_id and
ticket.priority_id(+) = priority.priority_id and
ticket.tickstat_id(+) = ticketstatus.tickstat_id and
ticket.tickettype_id(+) = tickettype.tickettype_id and
ticket.customer_id = customer.customer_id and customer.owner_id = #session.owner_id#
I get an error:
MERANT][ODBC Oracle driver][Oracle]ORA-01417: a table may be outer joined to at most one other table
How do I translate the code to ORACLE?

I think that your syntax is wrong. The (+) operator should be on the right hand table column, not the left hand table column if you want all rows on the left hand table column. If this syntax is really what you want, you can create underlying views for each join condiction.

Copy data from mysql to oracle database help?

Im an sql newb and trying to understand how I can automatically copy data from one dtabase to another systems database on the same server.
We have two differnt applications, but both share customer information, but one is on a win server, while the other is on oracle.
Each time a customer contacts us via online chat (win server, mysql), we want to copy their entire chat transcript into our CRM's (oracle) customer account. So the folks that use the CRM can see the past chat histories. I hope this makes sense.
Where can i look to get started on this?
Thanks

You could look at Heterogeneous Services (see the forum here Heterogeneous Connectivity but if you want to push data from mysql to oracle you might be better looking at it from the mssql side. I don't know what they offer.
It might be simpler to do it at the client end. ie cut and paste from the online chat application into a new utility which inserts into the oracle database.
Incidentally, this forum is specifically for the SQLDeveloper tool. You might get more general help in the "database - general" or "sql and pl/sql" forums

Is it possible to Migrate Live VMs from a Windows 2012 Hyper-V Cluster to a different 2012 R2 Cluster?

At the moment I'm in a bit of dilemma because I know that Windows 2012 supports "Shared Nothing Live Migration" but recently I got to know that this feature is available for stand alone Hyper-V Servers. My Setup is that I have
3 Servers running Windows Server 2012 Hyper-v Failover Cluster and I need to migrate everything to a new cluster running on Windows Server 2012 R2 and offcourse some VMs can't be turned off during migration so I need to do this live during production hours.
Another note is that both clusters will be running on the different LUNs since each cluster has its own CSVs. I need to know if it is possible to migrate such VMs/Roles Live without have any downtime of the VMs/Roles?

Yes, but one exception - live migration works only on "compatible cpu's". There actually is a setting in CPU for forcing compatibility
mode. If that is not set, and you mvoe for example from AMD to Intel, then - this is not possible in live migration, cluster or not.

"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

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

Data transfer from MySQL to Oracle Urgent!

Hi All,
We have a table in MySQL database and we need to transfer a subset of its data over to Oracle table. The table in MySQL is big, so we created a temp table trying to do it several times. The question is, we set the the primary key column in both MySQL temp table and Oracle table ( a varchar column), when we transfered the data over using "insert into table_name select * from table_name@hsdobc", Oracle always gave the "Null value for not Null column" error, and it's only existed for one row no matter how many rows we want to transfer, but MySQL temp table has no such null value for the primary key column, it's very strange. Anyone knows what the problem might be? Thanks very much in advance.

Hi, thanks for your answer. I checked the MySQL table again, and found that in both the original table and the temp table, there is a row with the primary key column value "null". Don't know what happened? Probably it's a MySQL bug.
It's not Primary Key NULL value. If your new Oracle Table has ANY column defined
NOT NULL and while inserting you have at least one value in one row of coming data is NULL - It will fail. You need either to drop NOT NULL constraint for that
column(s), or provide value for it.
Also you can drop that NOT NULL constraint, Insert your data as is,
Update your data to get rid off all NULLs and put NOT NULL constraint back on.
ALTER TABLE MY_NEW_TABLE MODIFY MY_NEW_COLUMN NULL;
UPDATE MY_NEW_TABLE SET MY_NEW_COLUMN = 'Some_Value';
ALTER TABLE MY_NEW_TABLE MODIFY MY_NEW_COLUMN NOT NULL;
