DMAP: Homogenous Migration on Oracle Database for AWS EC2 as Target

DMAP Ora2Ora Application Usage Instructions

Step 1: Launch the AMI. Log in to AWS Management Console and navigate to EC2. Click Launch Instance and select this DMAP Ora2Ora AMI. Choose instance type t3.xlarge or higher for optimal performance.

Step 2: Configure Security Group. Create or select a security group with inbound rules allowing SSH on port 22, DMAP Application Service on port 5004, DMAP Database UI on port 9090, Database Port 5433, Application Database Port 5434, and Python Service port 7002 from your IP address or as needed.

Step 3: Select or create a key pair, download the PEM file, review configuration and launch the instance. Wait for Running state and note the Public IP address.

Step 4: Connect to Instance. Open terminal and run chmod 400 followed by path to your PEM file. Connect via SSH using ssh -i followed by PEM file path and ec2-user@ followed by instance public IP.

Step 5: Start Docker Service. Run sudo systemctl enable docker then sudo systemctl start docker to enable and start Docker service.

Step 6: Launch Database Container. Run sudo docker run -d -it -p 5433:5432 -p 9090:8080 -p 7002:5002 -e UI_PORT=9090 -e SERVICE_PORT=7002 -e DB_PORT=5433 --name=dmap_db_prod_ora2ora ngdmapo/dmap_db_prod_ora2ora:latest

Step 7: Launch Application Container. Run sudo docker run -d -it -p 5434:5432 -p 5004:5002 --name=dmap_app_prod_ora2ora ngdmapo/dmap_app_prod_ora2ora:latest

Step 8: Verify containers are running using sudo docker ps. You should see both dmap_db_prod_ora2ora and dmap_app_prod_ora2ora containers with Up status.

Step 9: Access Application. Open browser and navigate to http:// followed by your instance public IP :5004/DMAP/#/login

Troubleshooting: If unable to access, check Security Group rules ensure port 5004 is open. Verify containers using sudo docker ps -a. Check logs using sudo docker logs dmap_app_prod_ora2ora or sudo docker logs dmap_db_prod_ora2ora. Restart containers if needed using sudo docker restart dmap_app_prod_ora2ora dmap_db_prod_ora2ora.

Port Configuration: Default ports are 5433 for database, 9090 for database UI, 7002 for Python service, 5434 for application database, and 5004 for application service. Ports can be customized but update security group accordingly.

Important: Database container must start before application container. All commands require sudo privileges. Ensure chosen ports are available and not used by other processes.
