These steps are required after the TEST-EC2-all.sh script runs: 1) Create the necessary directory(ies) on the servers: ec2-54-82-3-111.compute-1.amazonaws.com: /home/oracle/TEST 2) Copy the DDC files to the server(s) where the processes will run: ec2-54-82-3-111.compute-1.amazonaws.com: /home/oracle/TESTC/TEST-EC2-APPLY.ddc sourceserver.com: /home/oracle/TEST/TEST-EC2-MINE.ddc 3) Review that path to dbvrep executable is correct in the run scripts: /home/oracle/TEST/TEST-EC2-run-sourceserver.sh /home/oracle/TEST/TEST-EC2-run-ec2-54-82-3-111.compute-1.amazonaws.com.sh 4) Copy the run script to the server(s) where the processes will run: sourceserver.com: /home/oracle/TEST/TEST-EC2-run-dbvrds01.sh ec2-54-82-3-111.compute-1.amazonaws.com: /home/oracle/TEST/TEST-EC2-run-ec2-54-82-3-111.compute-1.amazonaws.com.sh 5) Ensure firewall is open for listen interfaces 0.0.0.0:7902, 0.0.0.0:7901 used by the processes. 6) Make sure the data on apply are in sync as of time when setup was run. Scripts for Data Pump/export/DDL were created as requested: /home/oracle/TEST/APPLY.sh Create referenced database links (if any) before running the scripts. 7) Start the replication processes on all servers: sourceserver.com: /home/oracle/TEST/TEST-EC2-run-sourceserver.com.sh ec2-54-82-3-111.compute-1.amazonaws.com: /home/oracle/TEST/TEST-EC2-run-ec2-54-82-3-111.compute-1.amazonaws.com.sh 8) Start the console to monitor the progress: /home/oracle/TEST/start-console.sh The above list is stored in /home/oracle/TEST/Nextsteps.txt. |
