Example Migration Process
Let’s walk through a simplified example of migrating a sample Oracle database to MySQL using Oracle SQL Developer and MySQL Workbench.
Export Data from Oracle
expdp system/password@orcl schemas=my_schema directory=export_dir dumpfile=my_schema.dmp logfile=export.log
Convert Schema:Use AWS Schema Conversion Tool (SCT) to convert Oracle schema to MySQL:
Load Data into MySQL
LOAD DATA INFILE '/path/to/data.csv' INTO TABLE my_table FIELDS TERMINATED BY ',' LINES TERMINATED BY '\n';
Test and Validate: Execute SQL queries to verify data integrity
SELECT * FROM my_table WHERE id = 1;
Performance Optimization: Optimize MySQL indexes and configuration parameters
CREATE INDEX idx_name ON my_table (name);
Deployment and Monitoring:Deploy the migrated application to production and monitor MySQL performance using MySQL Enterprise Monitor.
