Oracle database migration tools

So it can be run on any computer that can access the Oracle Enterprise Repository server. It runs much faster if run on the same computer as the Oracle Enterprise Repository server.

Preview the results of a migration, without committing any changes to Oracle Enterprise Repository. This section describes the migration tool functionality for ALER 3. This section contains the following topics:. Section 3. An interface asset is created, and related to the service. The FileInfo is removed from the service and endpoint assets. The SFID fingerprint is removed from the service and endpoint assets. Any non-artifact asset that is migrated gets a new internal name, which is used for duplicate checking.

Pre-existing service, endpoint, and business process assets keep their original name. New assets are named according to the Harvester's naming rules. Manifest metadata entries are created on the migrated assets, as in Harvester, to support the new download functionality in Oracle Enterprise Repository. Assets that were imported into Oracle Enterprise Repository in an ad-hoc manner are migrated as described in Section 3.

But an asset of another type, for example, "TestCase", are not migrated. Recalculates and store the SFID for artifact assets from the original artifact files, using the 11gR1 fingerprinting code. Updates the internal. Artifacts that were harvested from remote URLs have the FileInfo updated to point to the remote location to match the Manifest. Artifacts that were harvested from local files have the Manifest updated to point to the repository download URL to match the FileInfo.

Deletes obsolete internal. Connects to the UDDI registry to get these. The registry-name and registry-url elements are set from the original internal. The service-key is read from the UDDI registry during migration. These are read from the UDDI registry during migration. This is read from the UDDI registry during migration.

Converts the internal. The migration tool is available in the Unzip this file to a directory on your computer. The migration tool can be run in the command line using the migrate.

Before running migrate. Table Comman Line Script. This must be Java version 5 or higher. In normal cases, there is no need to set this variable. However, a common exception when you need to set this variable is when your computer is inside a firewall, and you need to use an HTTP proxy to access external servers. You can preview the results of a migration in the Data Migration tool, without committing any changes to Oracle Enterprise Repository, by using the command-line options.

Table describes the command-line options for the Data Migration tool. If true, the data migration tool runs in the preview mode. A detailed information about successes and failures are logged. No changes are committed to Oracle Enterprise Repository. The following features introduced in Oracle Database 12 c Release 1, collectively enhance the migration process of non-Oracle database applications to Oracle Database:.

The conversion of the non-Oracle SQL statements of the applications is a manual and tedious process. To minimize the effort, or to eliminate the necessity for converting these statements, Oracle Database Release 12 c introduces a new feature called SQL Translation Framework using which these SQL statements can be accepted from client applications and then can be translated at run-time before execution.

The translated statements are then saved in the SQL Translation Profile, so that you can examine and edit at your discretion. This feature has two key benefits:. SQL statements are translated with the following restrictions:.

Therefore, these values are not converted to their index value if retrieved in a numeric context. No validation is performed for insertion. Migration from database systems that use identity columns is simplified and can take advantage of this new functionality.

Example creates a table with an identity column, which generated by default. When explicit null s are inserted into the identity column, the default behavior is to use the sequence generator. This feature eliminates the overhead of re-writing the client-side code. Implicit statement results enable you to write a stored procedure, where each intended query the statement after the FOR keyword is part of the OPEN cursor variable. Starting with Oracle Database 12 c Release 1, JDBC applications provide support for implicit results through the following new functions:.

It is called iteratively by C applications to retrieve each implicit result from stored procedures and anonymous blocks. Implicit results consume rows directly from a stored procedure without going through a RefCursor. ODBC support for implicit results enables the migration of Sybase and SQL Server applications that use multiple result sets bundled in the stored procedures.

Oracle achieves this by sending the statements or procedures to the server, where the non-Oracle SQL is translated to Oracle syntax. Example shows how to dynamically call a subprogram with a nested table formal parameter. Example Invoking a subprogram with a nested table formal parameter. Starting with this release, Oracle Database provides a row limiting clause that enables native SQL support for query row limits and row offsets.

If your application has queries that limit the number of rows returned or offset the starting row of the results, this feature significantly reduces SQL complexity for such queries. Many applications that you want to migrate to Oracle Database from other databases have Java applications that use JDBC to connect to the database. For every type of migration, a few of the SQL statements used in the application must change, and some indexes must be re-built.
