What s New in Oracle Migration Workbench This section describes new features of Migration Workbench Release and provides pointers to additional information. Microsoft Access Plug-in and Exporter Enhancements The Microsoft Access plug-in now supports migrations from Microsoft Access XP (2002) and 2003, in addition to the other previously supported versions. The plug-in also now supports the migration of Microsoft Access queries to Oracle views. Several changes have been made to the Exporter tool, which generates XML files representing the database schema and table data for Microsoft Access databases. You can now simultaneously export multiple MDB files into a single schema or multiple schemas. The usability of the tool has also been enhanced. For information about how to use the Exporter tool, see the online help available within the tool. IBM Informix Dynamic Server Plug-in Updated The Informix Dynamic Server plug-in now supports migrations from Informix Dynamic Server 7.3, 9.1, 9.2, 9.3, and 9.4. It also supports the migration of collection data types and sequences. The procedural language parser has been updated to accommodate the migration of these additional objects. The following subsections describe additional changes in more detail. Row Data Support This release supports the migration of row data types (NAMED and UNNAMED) in Informix Dynamic Server tables, and it includes the following features: Row data types can be migrated to Oracle object data types. The name of a generated object data type can be changed. Nested row types are supported. Collection data types nested within a row type can be migrated, but you must use the online data migration capability. The following basic data types are supported as row field data types (including nested row types): CHAR DATE 3

4 DATETIME DECIMAL FLOAT INT8 INTEGER MONEY NCHAR NVARCHAR SMALLINT SMALLFLOAT VARCHAR The LVARCHAR (size less than 4000) opaque data type is supported as row data types (excluding nested row types). The following data types are not supported as row data type fields: Opaque data types (including built-in opaque data types such as BOOLEAN, BLOB, and CLOB) User-defined data types INTERVAL SERIAL, SERIAL8, BYTE, and TEXT. (In Informix, these data types are not supported as field types in unnamed row types or in named row types that are to be used as a column type in a table.) Sequence Support This release supports the migration of Informix Dynamic Server sequences to Oracle sequences. SQL Statement Support SQL statements: CASE SPL and CALL SPL statements This release supports the following additional support for CREATE FUNCTION support for the INTO keyword EXECUTE FUN CTION statement in an Informix SPL body TRUNCATE statement CREATE TABLE and CREATE VIEW support for the AS TYPE clause T-SQL Parser Enhancement The T-SQL parser has been improved to generate clearer, more concise PL/SQL code by default. This code is easier to read, maintain, and test. Advanced parse options can be specified in either the Source Model or Oracle Model. Using the Sybase Adaptive Server jconnect 5.5 for JDBC Driver Migration Workbench for Linux uses the jconnect 5.5 for JDBC driver to connect to Sybase Adaptive Server. For more information about downloading and using this driver, see the Oracle Migration Workbench User s Guide. 4

5 Usability and Performance Enhancements Several enhancements have been made to reduce the effort required to complete a migration and to improve the performance of the Migration Workbench.

8 Configuring Migration Workbench to Use the Default Browser To view Migration Workbench HTML files, such as the Quick Tour, Migration Workbench attempts to activate the default browser on a Windows system. However, Migration Workbench does not know the name or path of the default browser. It relies on the Windows or Linux x86 file associations to activate the browser, if one exists. To avoid any Web browser problems, Migration Workbench uses the state.properties file to specify the exact path of the system browser. The state.properties file is automatically generated the first time you launch Migration Workbench. If there is a problem executing the browser command on a Windows or Linux x86 system, you receive the following error message: Problem executing Browser command command executed. Please specify the browser path in the c:\omwb1010\omwb\state.properties initialization file for the BROWSER_PATH property, then restart the Migration Workbench. For more information please read the release notes. To ensure that Migration Workbench launches the correct browser, edit the state.properties file as follows: 1. Close Migration Workbench. 2. Navigate to the following directory: On Windows: OMWB_install_dir\Omwb\bin On UNIX: OMWB_install_dir/Omwb/bin 3. Open the state.properties file. 4. In the BROWSER_PATH section, enter the exact path of the browser Migration Workbench should use. For example: On Windows: c:\program Files\Netscape\Communicator\Program\Netscape.exe On UNIX: user/local/bin/mozilla 5. From the File menu, select Save, then close the file. 6. Restart Migration Workbench for the changes to take effect. Using a Workbench Repository Created by a Previous Release This release of Migration Workbench does not support Workbench repositories created by previous releases of Migration Workbench. If you log in to the current release of Migration Workbench with a Workbench repository user from an earlier release, you cannot continue unless you re-create the Workbench repository. Re-creating the Workbench repository deletes all information from the 8

9 earlier version. Oracle recommends that you create a specific Workbench repository user account, for example, REPUSER. For more information about creating the REPUSER account, see the Oracle Migration Workbench User s Guide. Removing the Migration Workbench To remove this release of Migration Workbench, delete the entire Migration Workbench installation directory OMWB_install_dir. No other action is required. Note: For Migration Workbench Release or earlier, use Oracle Universal Installer to remove the product. Documentation Updates The following Migration Workbench documentation is updated for this release: Online help for the Migration Workbench user interface, including information specific to the following plug-ins: Microsoft Access, Microsoft SQL Server and Sybase Adaptive Server, and Informix Dynamic Server Online help for the Exporter tool for Microsoft Access Oracle Migration Workbench User s Guide Oracle Migration Workbench Frequently Asked Questions (FAQ) Reference Guide for Microsoft Access Migrations Reference Guide for Microsoft SQL Server and Sybase Adaptive Server Migrations Reference Guide for Informix Dynamic Server Migrations Problems and Considerations To report a problem, see the instructions in the Oracle Migration Workbench Support Web site at: This section contains the following topics: Migrating a Microsoft Access Database to Oracle10g Lite Multi-level Linked Tables in Microsoft Access Informix Dynamic Server Migration Issues Open Bugs Migrating a Microsoft Access Database to Oracle10g Lite If you use the default repository (Oracle Lite) to migrate a Microsoft Access database, and if you later click Action > Modify Microsoft Access Database and try to link the Microsoft Access database with an Oracle10g Lite database, the following error will occur: Unable to connect to target database. java.sql.sqlexception: Specified driver could not be loaded due to system error 127 (Oracle Lite 40 ODBC Driver). 9

10 Instead, to migrate a Microsoft Access database to Oracle10g Lite, follow these steps: 1. Use an Oracle9i or Oracle10g database as the Migration Workbench repository. (That is, do not use the default Oracle Lite repository.) 2. Migrate the schema and the table data to Oracle10g Lite. 3. Exit the Migration Workbench. 4. Start the Migration Workbench. 5. Click Action > Modify Microsoft Access Database and link the Microsoft Access database with an Oracle10g Lite database. Multi-level Linked Tables in Microsoft Access Migration Workbench only supports one level of linked tables. If you have a table with links to a second table, these links are preserved. However, links in the second table are not migrated to Oracle. Informix Dynamic Server Migration Issues The following issues and considerations apply to Informix Dynamic Server migrations: Opaque data types and user-defined types are not supported as the field of a row type. When you use offline scripts to move data, table data having a NULL value (atomic null) for any of its row type columns, or having any row data type columns with an atomically null nested row type, will not be migrated correctly. A row typed table is not supported. Such tables will be migrated to untyped tables. Migrated sequences in Oracle will have a starting value taken from the START WITH option (specified or default value) when the sequence was created in Informix Dynamic Server; they will not have their current value. To use the current values, you must obtain the current values from Informix Dynamic Server, and either specify these values as starting values for sequences or (after the migration) drop the sequences and re-create them with the desired starting values. Opaque, row type (named or unnamed), and UDT are not supported as collection elements. The maximum size for the VARRAY type is 100 by default; however, you can change this value during the migration. If you use an offline script to move complex data with date elements, date column formats other than MM/DD/YYYY are not supported. Either use the online Migration Workbench interface, or modify the SQL*Loader control (.ctl) file for the affected tables before performing the load operation. For offline capture of the Source Model from an Informix Dynamic Server database, use the appropriate script file. The file name and location depends on your Informix Dynamic Server release number, as explained in the 10

11 chapter on disconnected source model loading in Oracle Migration Workbench Reference Guide for Informix Dynamic Server Migrations. If you convert script files for offline capture to UNIX, you must create offline capture files in Linux x86, not Windows. Open Bugs The following are known issues with this release of Migration Workbench: Bug Database Names That Contain Special Characters Do Not Work If a database name in the source database contains special characters, such as a dash (-), Migration Workbench cannot extract that database. Workaround To migrate a database name that contains special characters: 1. Create a database with a name that does not contain special characters. 2. Copy the schema and data from the database containing special characters to the new database. Bug In Stored Procedures and Trigger T-SQL Code, DBO is Mapped to Unknown The user dbo is set to unknown in the T-SQL code of stored procedures and triggers. Workaround Before migrating, edit the PL/SQL text in the Oracle Model to reset the user dbo to the required value. Bug Two Instances of Migration Workbench Might Cause Uniqueness Problems Two instances of Migration Workbench running at the same time may create problems. For example, if you create a tablespace with the name TABSPC in one instance, you may have problems if you create the same tablespace in another instance of Migration Workbench. This causes two tablespaces of the same name to exist in the Workbench repository that results in unnecessary errors during migration. Workaround Oracle recommends that you run only a single instance of Migration Workbench. Bug Custom Tablespace: Constraints Need to be Given for the OM_TABLESPACE_ INFO Migration Workbench does not validate the directory path entered in the Data File Directory option on the General page of the Options dialog. You may have problems creating tablespaces if the directory path is incorrect or invalid. Workaround Ensure that the directory path is correct in the Data File Directory option of the Options dialog. You should also ensure that the directory path uses the correct format for your destination platform. To verify or change the directory path, from the Tools menu, select Options. If the directory path is incorrect, modify it or leave it blank. If this field is blank, Migration Workbench uses the default data file directory for the destination database. 11

12 Bug Updating Default Tablespace Under One Schema Filters Across All Schema If you make changes to the Indexes: Default Storage Options or Tables: Default Storage Options property sheet for one user, they apply to all users. Workaround Oracle recommends that after you migrate the database using Migration Workbench, you use Oracle Enterprise Manager to make changes to the index or table storage options. You can also use Migration Workbench to make changes to the default storage options that only apply to a specific user for that index or table. From the Oracle Model tree, make your changes by selecting the Override Default Storage Options tab from the specific index or table, not the Default Storage Options tab for all indexes or tables. Bug JAVA.SQL.EXCEPTION: [POL-4005] Null Class Object is Not Allowed When you are using the default Workbench repository, Migration Workbench raises this error when it attempts to create an index on an empty Source Model table column. Workaround Ignore this error, as it has no effect on the migration. Bug Filenames Greater Than 30 Characters Must Be Considered During Capture If you are migrating a Microsoft Access database, the database name (not including the.mdb extension) must be less than or equal to 30 bytes, because it is stored in a field of type VARCHAR2(30). If the name is too long, an exception is recorded in the Error.log file. Workaround Rename the Microsoft Access database file so that the name is less than or equal to 30 bytes.
