Preparing for Exadata - Oracle Exadata Recipes: A Problem-Solution Approach - page 141

After you have entered your Exadata network names and IP addresses in your DNS server, simply run
checkip.sh from a location on your network that has connectivity to each network in your planned Exadata
environment. As stated, the checkip.sh script will read your dbm.dat file, as built by Oracle based on your database
machine configuration worksheet. checkip.sh logs its output to a file called dbm.out in the directory in which you ran
checkip.sh . Following is a sample, abbreviated output of a successful checkip.sh execution prior to an Exadata Quarter
Rack installation. In this output, we will number each line and explain what each section means after the output:
1. Running in mode pre_applyconfig
2. Using name server 11.11.1.250 found in dbm.dat for all DNS lookups
