hms_ts_setup.sh v2.4.0:
* Adjusted so lack of any active SDP instances is no longer an error
condition, and results in an info message (not even a warning).
Previously, the typical scenario was to run this after installing a
live data p4d instance on the same host. Now it is becoming more
common to install HMS right after running the Helix Installer, with
no live data instances, on a Linux bastion host where the p4_hms
instance is the only one intended to be on the machine.
* Minor style consistency changes with usage of quotes.
