Clustering is something that's already on the i and can
help you getting more from your i infrastructure.

You don't generally run into that kind of bottleneck when applications are running under the native virtual machine, using native task
dispatching, and workload management. But we tend to be an industry geared toward distributed architecture anyway. Added complexity. Increased TCO.

I'd rather deploy applications to IBM i libraries, and maybe to an additional mirrored server, and be done with it.

I am not definitive on this because I am only working on V5R3 .... at
that release for sure, the i is not easy to run 24/7. I am making a
lot of code changes to a legacy system, writing and deploying new
apps. There is a constant battle with system locks. SQL often retains
a lock on a file after the query is completed. I have to run the
ALCOBJ CONFLICT(*RQSRLS) command to free the locks up when replacing
the file. SQL VIEWS also stay locked for some reason, even after the
using job is ended. I use SQL VIEWs a lot to get a handle on legacy
databases. When I replace a view in PRD, the system eventually
releases the lock on the view being replaced, but it takes about 15
minutes. Then of course there are all those locks retained by legacy
code on data and device files ( and database records ). Would help a
lot to be able to tell the system to at least temporarily release
those locks. The system is way behind on PTFs because we cant afford
the down time ( and lack of knowledge on how to minimize the time
needed in restricted state to apply the PTFs ).
