Calculating optimal ulimit with RDA - Health Check

That's params from installation docs :

Open file descriptors	nofile	at least 1024	at least 65536
Number of processes available to a single user	nproc	at least 2047	at least 16384
Size of the stack segment of the process	stack	at least 10240 KB	at least 10240 KB, and at most 32768 KB

 We can confirm these parameters with RDA - Health Check utility. RDA - Health Check / Validation Engine Guide (Doc ID 250262.1)
