EXADATA - Network traffic slow while rman backups are being run
We pull some heavy data using data database links (pulling data into the exadata from a non exadata system). Whenever these data pulls occur at the same time as our full database backups, data pulls are slow. When Oracle ACS configured the Exadata machines, we had requested a separate backup for backup traffic to flow. But obviously client traffic seems to be interfering with backup traffic in this case. How to validate the setup is indeed right? How to make sure that backup network traffic (RMAN) gets routed through the backup interface?
Re: EXADATA - Network traffic slow while rman backups are being run
You can check it on your OS ( Linux in your case , as your system is Exadata)
Check and note the ip adress that belongs to the backup machine that you send your backup data to.
Check the network interfaces that are configured on your Exadata compute nodes (using ifconfig)
Check their types optionally (using ethtool)
Use route command to display the routes.
You should see that the route of your backup destination is based on a seperate network interface/s.. I mean it should be based on the network interfaces, which are different from your admin and client network..
