When installing Splunk UF to Solaris OS, error message: couldn't set locale correctly

[1000315118]

First time seeing this issue.

Running:

l  locale -a
l  which whoami

The result for this command would be as below:

ns4.xxx% locale -a
C
POSIX
iso_8859_1
ja
ja_JP.PCK
ja_JP.UTF-8
ja_JP.eucJP
ns4.xxx%
ns4.xxx% which whoami
no whoami in /usr/bin /bin

This was due to inadequate libraries on the Solaris OS.
