The problem stemmed from the fact that I have several modes or operations that a script may run against several servers. Almost all of the different operations required some base set of config to be derived by executing various queries on the remote servers locally.
All of these jobs required a load of config to be passed into them, I wrapped invoke-command in a loop that read hosts and their unique attributes from a file then spawned the jobs. Some of these jobs required state information to be passed between them, but I could not execute the sequence all at once unless each stage was successful on each node. If a node had an issue, manual intervention would be required otherwise any node that proceeded would cause the nodes not passing checks to be invalid and the clusters would be destroyed. So each step has to be invoked manually. I also write state info the successive jobs need to an xml file... Burden came when developing the script, the script blocks for each stage reused code and every change required amending each script block. So I split them into separate files, set them to vars, and sourced them in one small script which then assembled them all including the params and state info into one large script block that is sent to to each node, the single arg passed in then invokes the required function. Thats how I arrived at the exact example I posted, vars changed as they were meaningless. If I use single quotes, how do I perform the substitution? I am also not sure what you mean by decorated variables, a small nudge would be very appreciated:) Thanks! jlc ________________________________________ From: Michael B.

And, by the way, scriptblocks are always serialized as strings - so you may not actually be helping yourself. ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to [email protected] with the body: unsubscribe ntsysadmin
