SOLUTION:

To implement the solution, please execute the following steps:

1. Locate the missing utilities. On most releases of unix, they are in /usr/ccs/bin
2. Include a reference to the utilities path in the $PATH environment variable for the applmgr user used to manage the instance. Remember to export the PATH for changes to take effect.
3. Rerun the command 'perl adcfgclone.pl appsTier'
