In Response To: Re: oninit: Not enough room in ROOT DBspace. (Martin Fuerderer )

I believe Anna said that the documentation says that you cannot adjust
"LOGFILES" without a re-init.... which is also incorrect, but very different
than just adding more logical logs.

Anna, the LOGFILES parameter can be adjusted without a re-init. It only needs
an engine bounce to take effect. Same goes for the LOGSIZE parameter. However
only new logs will be created with the new size... exisiting logs will not be
adjusted.

If you wish to add new logs of a *different* size than LOGSIZE, you must use
"onparams".

If you wish to change your existing logs to a new size, you can add new logs
of the new size, bounce the engine (making the new logs available for use),
"onmode -l" until one of the new logs is selected, "onmode -f" to force a
checkpoint and move the current log to the one selected, and the "onparams"
to drop the old logs.

(Caveat: This was the process under IDS 7*. It may have been streamlined under
IDS 9*)

That said, and with Martin's notes below, a general practice is to set a low
value for PHYSFILE and LOGSIZE, LOGFILES = 3, and a small ROOTSIZE (also,
obviously, a small disk slice for RootDB... saving you a ton of space!). After
the initialization (oninit -iv), you add your LOG and PHYS spaces, adjust the
LOG and PHYS values, and you are on your way.

Remember: Bounce the engine = "onmode -ky" and "oninit". Reinitialize and
wipe out everyting = "oninit -iv".

Hope this helps!
