Let's get understanding to calculate bandwidth between Database servers on Exadata. Exadata available for both 10Gig and 1Gig network configuration.
Here we have given example for 1Gig network configuration. Same methodology can be used for other network configuration.
There are multiple tools to calculate network bandwidth between two points.
Like, Iperf, NDT, NC, PCATTCP etc...
Here we will use NC utility to calculate bandwidth.
We have two database node on exadata
DB01
DB02
Step 1 Download nc-1.84-10.fc6.x86_64.rpm and copy on the nodes where you want to carry out the bandwidth test.
You can get this rpm from HERE
Step 2 Install RPM on both nodes.
[root@db01 ~]# rpm -ivh nc-1.84-10.fc6.x86_64.rpm

[root@db02 ~]# rpm -ivh nc-1.84-10.fc6.x86_64.rpm
Preparing... ################################## [100%]
1:nc ################################## [100%]
Step 3 Using NC utility start receiver on free port. Make sure port which you are using is not utilized. Here we have used 9999 port.
