Let’s deep diveinto the EnterpriseDB Platform
A Feature Rich Platform – which offers offer a range of tools,
and the EDB Postgres Migration Portal
What applications tostart with?
Good to Start with Avoid
• Developed using open standards
• Open standard connections
• Not much dependent on server side
code – stored procedures etc
• Vendor already supports Postgres or
EDB Postgres
• No RAC scalability requirement
• No need of flashback
• Uses proprietary connection method
e.g. tnsnames
• Multiple DBlink dependencies or
dependents
• Has dependencies on other
applications/databases
Migration Assessment usingMigration Portal
• How easy will it be to perform the migration?
• What are the risks?
• Will all my server side code (Stored procedures) work fine?
• Is my application compatible?
• How much testing effort will be needed?
Telecom case study: Schema migration
• Application Platform and drivers : Java (JDBC)
• Reason for Migration :
1. Operational cost reduction
2. Oracle License Cost
• Challenges :
1. Interval Partitions
2. Views
3. DB links

Government Use Case: Schema Migration
• Application Platform and drivers : application on Java (JDBC)
• Reason for Migration :
1. Oracle License Cost
2. Microservices
• Challenges :
1. Oracle RAC
2. Schema with more than 700 objects and Approx. 3TB size schema for migration
3. Oracle security features
4. Oracle unlogged tables
Training and operationalsupport
