kandi X-RAY | OracleTC Summary
OracleTC is a project created by Timothy High (and Eduardo Morelli, while working for Sakonnet Technology (For more background on this project, check out the blog post: The project is being released for public consumption based on popular demand with the official blessing of Sakonnet. I have done my best to "sanitize" the library here so as not to reveal any of the innards of Xenon itself, but hopefully have not hidden any information that would be useful for getting your own version up and running. Note that this project was never designed to work for the general case. It was written very specifically for the Xenon code base. However, the techniques used are applicable in general, and with a little elbow grease, it should be possible to measure test coverage of any PL/SQL library.

I am migrating data from an Oracle (12c non-pluggable) database to SQL server (2012) using T-SQL scripts in SSMS with the Oracle DB set up as a Linked server. The schemas are already synchronized so the only thing left is the data. The issues I face is with the time the migration takes and the amount of memory it consumes.
When running my script, it takes a very long time and initially I ran into memory issues on the SQL Server-server when migrating full tables, so I decided to split the migration of the tables into chunks of 1,000,000 rows at a time. However, it seems as if there is a "memory leak" in my code as the memory consumed by the query is increasing with every iteration, and the query is taking a very long time.
EDIT: I have dropped the indexes in the MS SQL Server database.
My script works, but when migrating the larger tables, the query will close in on the available memory and the migration is taking around 5 min per 1 mill rows in the start (and increasing slowly with every iteration). Of course the time is dependent on the amount of rows in the table etc. as well.
Data statistics: * Tables: ~1600 * Rows in total: ~1 Bill. (Largest table being 300 mill. rows)...

There are a number of approaches.
Remove indexes on SQL Server table you import the data to and create them again after the import.
Separate export, transfer and load. That means extract data on Oracle server to plain text files, then transfer them to SQL Server machine by ftp, then load them to SQL Server.
(Most effective way) Use MS SQL Server bulk load: https://docs.microsoft.com/en-us/sql/relational-databases/import-export/bulk-import-and-export-of-data-sql-server?view=sql-server-2017 In this case your 1m of records will not be processed through whole database but will be written directly to database files, it's much faster.

You can use OracleTC like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the OracleTC component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
