UDT additional poller: improve the install wizard (dbUpdates)

UDT additional poller: improve the install wizard (dbUpdates)

The Configuration wizard appears to run on an additional poller engine updates the database, in particular the indexes. Support case# 834741

This means you cannot run multiple install wizards at once to upgrade several additional pollers at once.

With a small install the dbUpdate probably complete quickly, but with a large install this causes deadlock and [at least] one of them will fail, causing the configuration wizard to fail on that additional poller.

I feel that dbUpdates should only be performed on the application server install, and that the additional pollers should only check/require that they have been installed there before moving on -- updating the database schema from additional poller installs seems like an idea fraught with challenge best left un-met.

Version: 3.2.2

I agree, seems redundant to have additional poller run same updates to DB that main engine does.  This also adds time to a very lengthy process already if you have several APEs and AWEs...assuming they don't break up dbupdates by nodes assigned to poller due to data integrity for time differences in updating main/additional...I dunno...my head hurts now.

I guess this is not only for UDT but for the rest of the SolarWinds modules which integrated in the main server and additional pollers
