SDA: How to migrate from Derby to Oracle or Microsoft SQL Server

0 Likes

Some pilots will have installed the default Derby database. As part of going into production implementers may  want to migrate what has been implemented into the production database.

 

 

Note: Derby is to be used for prototyping/testing/evaluation purposes only.

 

To Java tool can be used to achieve this.

The attached document describes the steps required to achieve and is to be used with the Tool found in the file: SDA-DB-Migrator.zip

 

Note: The Migration tool is not officially supported by Serena and Serena would encourage you to make a secure backup of the Derby Database before proceeding.

The following steps are described within the PDF Document:

Step 1: Install the DB Migrator tool
Step 2: Install the Database JAR file in the Migration tool
Step 3: Stop SDA Server
Step 4: Backup the current SDA profile
Step 5: Create an empty schema
Step 6: Start the SDA server
Step 7: Run the Migration script
Step 8: Review the final output
Step 9: Restart the SDA server
Step 10: Test the new database

 

For more information download the PDF Document and the accompanying Java tool SDA-DB-Migrator.zip.

  • Hello Alfredo can you please confirm all the inputs you gave to the script, by copying and pasting all the options supplied when running the script. Can you also confirm the database you are importing into and the version. Also the OS that the script is being run on. Thanks Paul
