Re-order patching across tiers? #1

Closed cmgrote closed 5 years ago

cmgrote commented 6 years ago

Currently patching is applied tier-by-tier, but all at once within a given tier. This could theoretically lead to a situation where the domain tier is patched ahead of the engine tier; ie. on an environment where all tiers are on the same system, the engine-specific patches may be applied after large service packs.

Not clear yet that this would be strictly necessary, but logging to track in case it eventually seems to be problematic.

May need to rotate amongst tiers installing patches to keep the tiers in-sync in terms of their patch-level during the patching process (?)

Would also be worthwhile doing some re-factoring of patching in general, to be able to more easily selectively include (or not) particular patches that are available for a given release -- ideally also having the system determine for itself (maybe from patch metadata?) whether a patch is broadly applicable on a given environment or not (?)
