Issues using Oracle SQL server Developer migration work bench

Hi all,
We are trying to migrate the application databases from SQL server 2000 to Oracle 10g using Oracle SQL Developer 1.2.1.32.13:
Following is the list of issues that we faced while trying out this migration on dev environment.
1. The data migration was successful for only around 90 tables out of the total 166 tables present. No error message was logged for the rest of the tables but still it was completed.
2. Some of the tables which had got the data inserted did not have the full data. Only some of the rows were inserted for these tables. Error message was logged only for few of the rows and not all.
3. Few error messages were logged which said problems about “Inserting ' ' into column <tablename>.<columnname>”. There was no such constraint in the target database that the particular column can not be null or can not have only a space. Please check the logs for the same error messages.
4. The status box at the end of migration had shown only 3 errors.
5. The total data for migration was around 500MB. The time taken for migration was around 75 minutes. Are there any optimization techniques that will improve the performance?
Please note that there were no Foreign Key references for the source schema or target schema.
Any pointers/info/resolutions related to above mentioned issues will be much useful for us.
Thanks,

Hi Adam,
There are 2 sets of scripts created for you.
1) For SQL Servers BCP to dump out the data to dat files
2) For Oracles SQL*Loader to load the dat files
You run the SQL Server BCP scripts on the machine with SQL Server.
The dat files will be dumped out on that server.
You can then move the dat files to your Oracle server.
Then run the Oracle SQL*Loader scripts to load the dat files into Oracle.
Give it a go and follow the doc and viewlets.
Your Questions:
So the datadump from the source location would be saved on my local disk?it will be saved on the same machine you run the bcp scripts from. Usually the same machine SQL Server is on, because you require SQL Server BCP tool.
So once it is migrated to the destination database will that dump be created automatically? Or do I need to modify the script to take care of this?I dont know what you mean by this, hopefully above clears things up.
The only modifications you need to make to the scripts are adding in the databasename username password servername. These are outlined in the scripts themselves. I would want to do something fancy like dump the dat files to a different directory, then you can modify the scripts, but you should understand what they do first.
Most people would have 500MB of space on their discs , so I can see the problem creating these dat files . The same goes for your 30 GB database.
I hope this helps, but as always you wont get a good idea of how it works until you give it a go.
Regards,
Dermot.

  • Workspace Issue Using Oracle Application Server

    Dear All,
    I've configured my Workspace using Oracle Application Server and now I can login to my workspace through this url http://<servername>:7777/workspace/.
    But somehow, at my workspace home, I cannot find the folder or Explore inside, which is to see my Financial Reporting.
    I'm login using admin and the privileged is already for administrator.
    Is there anyone ever face this problem..??
    Thanks.

    1. Correct the following path
    extension_dir = "D:/php/ext"
    (if your php is installed in D:/php, the above path is correct.
    2. Find the line ;extension=php_oci8.dll
    delete comment sign (;) and it will be :
    extension=php_oci8.dll

  • SQL Server 2000 Migration to Oracl 10g

    Hi,
    We are plannig to migrate the SQL Server 2000 to Oracle 10g. I have following queries.
    1. Does the Oracle SQL Developer tool is the one that to be used? (Previously OWMB used to support SQL Server 2000, but it is no longer supporting.)
    2. When I tried to migrate using Oracle SQL Developer tool, there were some errors for @@spid and the tool did go further?
    3. In OMWB it used to provide the details like how many DB objects migrated successfully and how many failed, how to generate similar reports in Oracle SQL Developer?
    Please let me know.

  • Accessing MySQL InnoDB tables via JDBC using Oracle SQL Developer

    I had posted a problem in the Oracle SQL Developer forum with how that application (v1.1) accesses MySQL InnoDB tables and someone replied that the "[data migration] team created the integration with MySQL", so I am posting here in hopes of learning more about the problem.
    Here's a summary:
    When I use Oracle SQL Developer to query MySQL InnoDB tables, I need to issue a "commit" before I do each query to ensure that I am getting current results. Otherwise, it appears to be using a snapshot as-of the last commit. Is this a problem with SQL Developer, or a JDBC configuration, or MySQL problem even?
    The full details are here:

  • Getting the schema using Oracle SQL Developer 1.5.1

    I need to generate a report in CSV/XLS format using Oracle SQL Developer 1.5.1 to get the schema details
    in the below format.
    Table Name: XXXXXXXXX
    Table Space Name: XXXXXXXXXXXXXXX
    Structure :
    Field Name Data Type Size
    Xxxxxxxx xxxxxx xxxxx
    Xxxxxxxx xxxxxx xxxxx
    Xxxxxxxx xxxxxx xxxxx
    Xxxxxxxx xxxxxx xxxxx
    Field level constraint:
    Xxxxxxxxxxxxxxxxxx
    Table Level Constraint:
    Xxxxxxxxxxxxxxxxxx
    Indexes:
    Index Name Column Name(s) Table space name
    Xxxxxxxx xxxxxxxxx xxxxxxxxxxxx
    Xxxxxxxx xxxxxxxxx xxxxxxxxxxxx
    Xxxxxxxx xxxxxxxxx xxxxxxxxxxxx
    Sequence Number:
    Xxxxxxxxxxxxxxxx
    Triggers:
    Xxxxxxxxxxxxxxxxxx
    I am using a query to do that, but I cannot run more than one queries in the Create Report Dialog.
    I went to the Menu->View->Reports. In that, I chose User Defined Reports, created a new folder called Schema Detail and in that a report named Schema Detail. I right click on that report, choose Edit option, Create Report Dialog opens.
    In the Create Report Dialog, I chose the option Script for Value of Style.
    In the SQL column I enter a query "select * from table_names". But, if I enter another query after that, it does not run and reports an error "SQL Error: ORA-00933: SQL command not properly ended
    00933. 00000 - SQL command not properly ended" Cause:    Action: "
    I end the first query with a semi colon, but it does not work.
    The queries run fine in a SQL Worksheet. There, I can terminate the first query with a semi colon and enter the second query. Then, I run both of them together so that result-set of second query appears after the second.
    Am I doing something wrong? Can someone please advise on how to get the information I need?
    Thanks a lot.

    You can do it in SQL Worksheet because you are running a script. You could run the script in SQL*Plus, and even start it from a bat/cmd file.
    Or if you want this as a User Defined Report, you might make it a PL/SQL style report. Here, all output is done through DBMS_OUTPUT.PUT or DBMS_OUTPUT.PUT_LINE. You can output HTML tags or plain text. I have an example in my paper for ODTUG Kaleidoscope 2009.

  • Can I use Oracle SQL Developer to "Move" data?

    Hi,
    The name of tables are different ?
    If I understood then try this below:
    e.g:
    C:\> exp user/[email protected] file=maytable.dmp tables=SAFETYADMIN_TBL_0022_43
    C:\> imp user/[email protected] file=mytable.dmp full=y
    After this import, then you can:
    [pre]
    C:\>sqlplus user/[email protected]
    SQL> insert into SAFETYUSER_TBL_0022_44
         select * from SAFETYADMIN_TBL_0022_43;
    SQL> drop table SAFETYADMIN_TBL_0022_43;Feedback if this is not that you want.

  • Can we use different Databases (Oracle & SQL Server) in one report?

    Post Author: venki5star
    CA Forum: .NET
    Hi there.
    Can we use different databases (Oracle & SQL Server) in a same report?
    If possible how?
    Another question,
    Can we change the Provider Name at runtime of the given report. If so the above question is useless...
    Thanks in Advance.

    I tried this using Oracle Provider for OLEDB (the one that supplied by Oracle Client) and Crystal Reports 9. you can drag the column into designer but the image does not appear in preview.
    I guess it's because CR does not recognized it as image, and there are no information that the blob data is an image at all.

  • How to use Oracle SQL Developer 4.0 to connect to Ms Access file with .accdb extension

    Hi all,
    I am using Oracle SQL Developer 4.0 and Ms Access 2013 under Windows 7 (64 bits)
    After browsing and selecting MS Access file with accdb extention, I got  an error message  :[Microsoft] " Data source name not found and no default driver specified".
    On Administravitve Tools=> ODBC Data Source Administrator=>Drivers I have                                                File                                date

    Would you please advise?
    Thank you very much in advance

    That MS Access driver is 64-bit, I think.  If SQL Developer, or JDK is 32-bit you need to use the 32-bit driver.   You can see if you have a 32-bit driver installed using  c:\windows\system32\odbcadm32.exe

    Hi,
    One prior post discussing the use of Java 7 is:
    SQL Developer 3.0  and Java SE 7?
    There is no need to uninstall any Java version (except if you have disk space constraints) and no problem switching between Java versions. This may be controlled in the sqldeveloper.conf file in your ...\sqldeveloper\sqldeveloper\bin directory via the SetJavaHome line. For example:
    #SetJavaHome ../../jdk
    SetJavaHome C:/Program Files/Java/jdk1.6.0_26
    #SetJavaHome C:/Program Files/Java/jdk1.7.0Regards,

  • Optimizing an SQL Query using Oracle SQL Developer

    Hi ,
    Currently i am using Oracle SQL Developer as my Database IDE .
    Is it possible to use Orqcles SQLDeveloper for the purpose of Optimizing an SQL Query ??
    For example assume i am having a query as :
    Select from Tranac_Master where CUST_STATAUS='Y' and JCC_REPORT='N'*
    Could anybody please tell me how can i use Oracle SQL Developer to optimize this query or any other SQL queries ??
    Please share your ideas , thanks in advance .

    1. Your query looks very simplistic as it is, so I fail to see how you can better optimise it (unless 'Tranac_Master' is a view, in which case I'd need to see the view details).
    2. No tool can automagically optimise your SQL to any degree of practical use. Very minor adjustments may be possible automatically, but really it is a question of you knowing your data & database design accurately, and then you applying your expert knowledge to tune it.

  • Migrate from Access 97 to Oracle using Migration Work Bench to mi

    When I try to use Migration work bench to migrate an Access 97 database to Oracle using OWB I get "failed to truncate Source Model ORA-00942 tables or view does not exist" error message and I could not go further.
    This happens during clearing the Source Model. Doe any one know what is this error means or any one had this problem before.
    Thanks
    Myl

    Hi Njha,
    Did you create the Source Model using OMWB and then delete the tables in the OMWB repository manually ? Or is there a chance that the tables in your repository could have been corrupted in some way ? The OMWB is simply trying to truncate the tables it filled when a previous attempt was made to capture the source model before it re-populates the tables with data from your subsequent attempt at a capture. If the tables it is trying to truncate have been deleted or are corrupt, this error will be displayed.
    A workaround to your problem would be to drop the schema you are using for the OMWB repository and create a new one.
    I hope this helps,
    Tom.
