TimesTen Migration from on-premises to OCI
Oracle TimesTen is an in-memory relational database that provides extreme application performance of low latency and high throughput. TimesTen is being deployed in three configurations namely
- TimesTen Classic
- TimesTen Cache
- TimesTen Scaleout.
Through this blog, we illustrate how to migrate the single node stand-alone TimesTen Database from On-Premise to Oracle Cloud Infrastructure (OCI).
Pre-Requisites
Few pre-requisites are required before initiating the migration process to Oracle Cloud. Before performing the migration process of the database, we need to consider below details:
- On-premise host details
- Database name, size, version, and edition
- Network bandwidth
- Checking the data available like object related information, users etc.
Migration Process
Subsequently, the migration process starts and In OCI we need to perform a few tasks which are being mentioned below:
- Launching compute instance
- Adding the required storage to compute instance
- Creating required OS users and groups and their permissions
- Allowing required port numbers and need to enable ports using firewall rules
- Obtain network connectivity between on-premise and OCI.
- Building standby
Using active standby pair replication for creating standby database
- Cut-Over
- Announcing downtime for cut-over operation.
- Change the roles of primary and standby database by failover operation.
Post-Migration Checks
After the migration is being completed, we have to consider a few more steps to ensure the data is being migrated without any unprecedented errors.
- Verifying whether full data got replicated or not and making sure there is no data loss.
- Testing application connectivity.
- Routing all connections to OCI.
Benefits
Migration from On-premise infrastructure to Oracle has its own advantages. Key benefits to mention are are;
Better Storage:
Oracle Cloud provides better storage and you can expand or shrink storage based upon your requirement.
Scalability:
Oracle Cloud provides horizontal scaling and vertical scaling features so that you can increase or decrease resources based upon your requirement.
Provides great security, high availability features.
