SQL developer online data move

Hi,
I am using SQL developer 2.1 to migrate tables from Sybase 12 database to oracle 11g.
I have used online data move option for moving sybase data into oracle tables, but even after data move is completed not all rows have been moved from sybase tables to corresponding oracle tables. Some rows are missing but still there is no error messege being displyed, how to find out what's going wrong.
Is there any log file that is being generated in case of oracle sql developer?
Please help me with this.

Hi Mandark,
This is a weakness of SQL Developers online datamove.
It doesn't have logging and you cannot tweak the data move itself.
It very basic SELECT * FROM -> INSERT INTO ... under the covers.
If some rows are failing to be inserted,but some rows are being inserted, in the same table.
Then my guess is that the data in some rows doesn't "fit" into the target row/column.
And the datatype mapping used to convert the tables/columns was not good enough.
Ex: Sybase column of VARCHAR(10000) mapped to Oracle VARCHAR2(4000).
Some data which is greater than 4000 chars.
Which causes the insert to fail for those rows with >4000 chars. But ok for other rows.
The solution (in this example) is to map Sybase VARCHAR(100000) to Oracle CLOB.
You can specify the data type mapping in the Convert page of the migration wizard.
Another workaround is to use Copy To Oracle.
http://dermotoneill.blogspot.com/2010/11/copy-to-oracle.html
This is a very simple data move feature again. But it works slightly differently than Online Data Move.
It has no logging or tweaking either, but may do the job "online" for you.
You should temporarily turn off any check constraints, triggers, keys on each table you want to move data with using this method.
If all those fail, then the only sure fire way would be to use Offline Data Move.

  • Sql Developer MSSql Migration, Online data move, image to long raw mapping

    Hello,
    my task is to migrate a MSSql Server Database to Oracle 10.2.0.4 with SQL Developer Version 2.1.1.64
    and JTDS JDBC Driver oracle.sqldeveloper.thirdparty.drivers.sqlserver 11.1.1.58.17.
    Capture, convert and online data move works except data mapping from MSSql image to Oracle long raw dataype.
    I need to map MsSql image to oracle blob, to achieve online data move!
    is Sql Developer online migration MsSql image to oracle long raw possible?
    I know that long raw is outdated, but i'm dba and not responsible for the software part.
    What options should i try? offline data move? can MS Bulk Copy Program export image data and SQL*Loader import into long raw?
    Any experience or tipp?
    Thanks

    Hi user12132314 ,
    I do not see any 'long raw' options on our current SQLServer 2005 data type mapping. (Raw is a separate 2000 byte data type).
    The usual route for SQLDeveloper is to go to Blob.
    Online - this is simple & automated.
    Offline - this actually goes via hex output in bcp to sqlldr, read in as CLOB which is then encoded to blob. (This is automated)
    (Online 'Copy to Oracle' option, right click on table, may be of use if advanced features not included in the select such as defaults are not required, it copies over a select * from table, including blobs)
    To move you from blob to long raw after migration can be done (easily enough if Oracle database >=10g so the stream does not have to be in smaller 'chunks')

    I can look into this if you want to go down this route.
    Note however that long raw has drawbacks and blob is preferred, see
    Oracle® Database SQL Language Reference
    11g Release 2 (11.2)

    for example one restriction is:
    A table can contain only one LONG column.

  • Same icons for objects in SQL Developer as Data Modeler

    Hello,
    would it be possible to display the same icons for objects in SQL Developer as Data Modeler?
    For example:
    - in SQLD a session temporary table has the icon of a table with an X symbol, in Data Modeler it is just a table icon.
    - in SQLD a materialized view has the icon of a table with 2 arrows, in data Modeler it is just a table icon.

    Hi Joop,
    I think you will find that in Data Modeler's Physical Model tree the same icons are used for temporary Tables and Materialized Views as in SQL Developer.

  • SQL Developer with Data Modeler, No Design Menu Option

    Using SQL Developer 3.0.04 Build MAIN-04.34 with Data Modeler. I have created a logical design and wish to forward engineer this to a relational model.
    I cannot seem to find the Design Menu option to use the >> Engineer to Relational Model option which is available under the Design Menu on the Stand Alone version of SQL Developer Data Modeler.
    Have checked the following locations:
    Tools -> Data Modeler
    View -> Data Modeler
    File -> Data Modeler
    Right Click on my Logical Design
    I have ensure that all my entities have the Engineer To property set to a valid Relational Model.
    Is this a bug or am I missing a menu option / configuration setting?
    Thanks in advance for any help

    Hi John,
    you can find ">> Engineer to Relational Mode" button among other buttons for logical diagram.

  • Using CVS in SQL Developer for Data Modeler changes.

    Hi,
    I am fairly new to SQL Developer Data Modeler and associated version control mechanisms.
    I am prototyping the storage of database designs and version control for the same, using the Data Modeler within SQL Developer. I have SQL Developer version 3.1.07.42 and I have also installed the CVS extension.
    I can connect to our CVS server through sspi protocol and external CVS executable and am able to check out modules.
    Below is the scenario where I am facing some issue:
    I open the design from the checked out module and make changes and save it. In the File navigator, I look for the files that have been modified or added newly.
    This behaves rather inconsistently in the sense that even after clicking on refresh button, sometimes it does not get refreshed. Next I try to look for the changes in Pending Changes(CVS) window. According to the other posts, I am supposed to look at the View - Data Modeler - Pending Changes window for data modeler changes but that shows up empty always( I am not sure if it is only tied to Subversion). But I do see the modified files/ files to be added to CVS under Versioning - CVS - Pending Changes window. The issue is that when I click on the refresh button in the window, all the files just vanish and all the counts show 0. Strangely if I go to Tools - Preferences - Versioning - CVS and just click OK, the pending changes window gets populated again( the counts are inconsistent at times).
    I believe this issue is fixed and should work correctly in 3.1.07.42 but it does not seem to be case.
    Also, I m not sure if I can use this CVS functionality available in SQL Dev for data modeler or should I be using an external client such as Wincvs for check in/ check out.
    Please help.
    Thanks

    Hi Joop,
    I think you will find that in Data Modeler's Physical Model tree the same icons are used for temporary Tables and Materialized Views as in SQL Developer.

  • Integration of  SQL Developer and Data Modelling - concerns.

    In aanother thread about OSDM connections, I commented that the development team for OSDM and the core product seem to separate and Sue responded.
    Sue Harper wrote:
    A clarification of the Data Modeling feedback application and this forum. The developers are part of the SQL Developer development team, but as for all our features, each developer has a focus area, so the Data Modeling developers will tend to answer those questions. The reason I said that they seem to be separate as that ODSM seems to be put together completely differently. I hit another example today. I downloaded a fresh copy of osdm without JDK. On starting it up, it complained it couldn't find a jre and quit. There was no prompt to specify the location as there is with SQLDevloper and there are no configuration files to edit.
    SQLDeveloper already has issues with different components doing the same differently. The number of problems has been reduced but it has taken some time and I am concerned that the introduction of a large body of new code will cause things to revert to the bad old days in terms of quality.
    I may or may not end up using OSDM, but I want to have the choice. I don't want components I don't use becoming part of the application and adding bloat. The migration components are a case in point. The "migration workbench" ought to be a completely separate add-in rather than a core component and I hope this is down with OSDM.

    Jim,
    "I don't want components I don't use becoming part of the application and adding bloat." Absolutely. and we agree. SQL Developer Data Modeling will be a separate standalone product so that users who don't want to use SQL Developer, but who do want to model will have that option. The nice thing about an integrated solution is that if you are doing database work and then want to do some modeling, you are in one tool. Our current plans are to release the standalone product in the initial production release and then follow that with the extension to SQL Developer depending on the customer demand. We do plan to release a read only viewer as part of SQL Developer 2.0. This will be an extension, which like the Migration extension, you can switch off. and from your note, you'd prefer the reverse, that these new extensions are pieces you choose to include and not choose to exclude.
    I'm not certain we'll get agreement on this, but I'll be interested. Just this morning I was updating a thread were the request was for all the pieces to be there working out of the box.

  • Sql Developer and Data Guard enabled instance

    I have version 1.1.2.25 SQL Developer and when I try to connect to Oracle 10gR2 instance which is data guard enabled and its logical standby it spits few message, and then connects, but data is not visible from any table.
    Is there any way to see data and other code while in logical standby instance which only in read only mode?
    Thanks.

    This problem came when I tried to connect to Oracle
    instance which is a logical standby in data guard
    setup. Eventually connection is made and then you can
    not see any object.
    In logical standby database its suppose to be read
    only and should be available for query.
    In TOAD you can see every thing and when you want to
    make any change ,it spits an error and wouldn't allow
    you to make any change.
    My question was, why SQL Developer is not showing the
    objects in the list and its contains.Perhaps we could help you if you told us what the error was.

  • Will SQL Developer support data type anydata

    Will SQL Developer support datatype sys.anydata in future releases?
    Currently SQL Developer will not show any data for columns of type anydata.
    Example:
    create table t1 (id number, col1 sys.anydata);
    insert into t1 values(1,sys.anydata.convertvarchar2('TEST'));
    IF I export data from this table something like
    Insert into T1 (ID,COL1) values (1,'SYS.ANYDATA'); will be generated.
    The grid will display 'sys.anydata' for this column

  • Online Migration using SQL developer

    Hi All,
    We are planning to migrate our production SQL server.2005 database to oracle 10g. If I use online migration using Oracle SQL Developer Tool to migrate data from SQL server 2005 to Oracle 10g, then will it migrate all those records that are inserted into SQL server 2005 LIVE database after the time when online migration process started?
    For example let say the migration process started at 10:00 PM in the night and it found 200,00,000 records in transaction table, it will take 3-4 hours to migrate all of them to oracle, now during this migration time the LIVE SQL server database will still be getting new records, so will 200,00,000 plus newly inserted records will get migrated to Oracle 10g or only those which were initially counted when migration started?
    Kindly advise!
    Best Regards!
    Irfan

    Hi Irfan,
    It sounds easy to find that out by a little test. I would expect that only those records will be transferred that are in the remote table at the moment when the migration started. Online data move uses COPY via the JDBC connection, as far as I know.
    200,000,000 records and an online data move is a contradiction. From the manual:
    Mode: Online causes the table data to be moved by SQL Developer when you have completed the necessary information in the wizard; Offline causes SQL Developer to generate scripts after you have completed the necessary information in the wizard, and you must later run those scripts if you want to move the data. (Online moves are convenient for moving small data sets; offline moves are useful for moving large volumes of data.)
    If you are using offline data move, then you are using BCP to unload the data from the SQL Server database, and then the rules of BCP apply how the records are unloaded.
    What are you trying to achieve? Do you want to keep the two databases in synch? Then a migration does not seem to me the best way. There are other products, like the Database Gateway for MS SQL Server, or the Golden Gate product.
    Best regards

  • Using DEBUG Mode in Oracle SQL Developer Data Modeler to Log SQL

    Hello,
    I am looking for the possibilty to enable the logging of SQL in Data Modeler.
    Jeff Smith wrote an article how to do this for SQL Developer, for Data Modeler there are other configuration files. Does anyone have an idea?
    Best regards,
    Joop

    Hello Philip,
    the URL to the article of Jeff is: http://www.thatjeffsmith.com/archive/2012/10/using-debug-mode-in-oracle-sql-developer-to-log-sql/
    in the install directory of Data Modeler 3.3.0.734 exists a file datamodeler\datamodeler\bin\datamodeler.conf. This analogue the situation for sql Developer.
    However in this file there is no reference to a (non)debug file.
    In ide/bin directory there is a ide-logging-debug.conf and ide-logging.conf file. But they are not referenced. Should one of them be included?

  • File with pls extension opens with data modeler instead of sql developer

    Hello,
    I have both SQL Developer and Data Modeler installed as separate installations. If I  click in  the Windows File navigator on a file with the extension pls, the SQL Developer should open since the pls extension has been connected to SQL Developer.
    If I have neither SQLD nor DM open, SQLD opens -> ok
    If I have only SQLD open, the file is opened in SQLD -> ok
    If I have only DM open, the file is opened in DM -> not ok
    If I have both SQLD and DM open, the last started application opens the file -> sometimes ok
    Is it possible to manage the opening of a pls to open always in SQL Developer?
    Joop

    This is quite an old problem which I have seen with JDeveloper and SQLDeveloper so it may be framework related. I don't currently have both installed to check it out, but as it has been around a long time I doubt it has gone away.
    SQL files would open in either JDeveloper or SQL Developer following the pattern Joop described. Java files would only ever open in JDeveloper.    IIRC there was never a SQL file association for JDeveloper and SQLDeveloper was always the default.

  • SQL Developer problem. Rows without columns on data tab

    Hello,
    I have a strange behavior in Oracle SQL Developer Version 2.1.0.63. When I'm trying to open the "Data tab" for some tables, SQL Developer shows data rows but without columns! It seems that I can select different rows but I can't see neither any data nor column names.
    Under the filter setting there are no available columns either.
    At the same time, when I'm trying to open sys tables they are displayed normally.
    From the other side, those tables which are not displayed correctly in 2.1.0.63, could be opened in Version 1.5.5 without any problems.
    Do you have any ideas?
    Thanks in advance.

    blease give me asolution urgentley.....thanks

    Hi,
    SQL Developer 3.0 EA4 contains a the new Data Miner Workflow based interface.
    The old Data Miner (10.2/11.1) is in maintenance mode going forward.
    This will also mean that we will not porting the old Data Miner PL/SQL Package extension forward to new SQL Developer releases.
    However, you can always generate the pl/sql package directly from Data Miner 10.2/11.2 which will generate a file on your client which you can then edit/run using SQL Developer.
    Data Miner 11.2 offers sql and sql script generation as well, but it is currently limited to the transformation nodes.
    Thanks, Mark
