When doing an install on a 2 node system with 4 -8 JVMs for Servicenow on each directory do I have other options for this install call line?

$ java -jar glide-<release version>.zip -m dist-upgrade -c sample_16000 -a

For example if an already backing up service with incremental and full backup and at the point of the upgrade doing VMsnapshots is there a flag or option the skips the local file backup process ( it wastes time)?

Also is there way to pass into the installer command java every dir on the host? like see below

java -jar glide-<release version>.zip -m dist-upgrade -c sample_16000 sample_16001 sample_16002 sample_16004 sample_16003 -a

Or do I have call each one individually? And can I call JVM on another host in the list in the same command line?

Is there a flag that skips checking if the service is off and stopping the service? I do I hard rolling stop of the services before upgrading; that check for the service being off seems to waste time also.

Any ways that I can call and run script faster?

Also see attached is it ok to run the script like this? Basically I am calling the installer in succession in a bash script?

I realized after a coworker told me make that script parallel not serial that will speed it up.

So I have this is way to run a dist install on a few nodes at least at the same time if I stop then all beforehand

--upgrade-war-only - Servicenow said is for them only

same as -x glide.installation.developer=true
