Hi,

there can be 32767 databases (don=B4t no if including the system one,
but I assume that, let me know if you touch the magic number above :-)
per instance.

HTH, jens Suessmeyer.

hi,
[quoted text, click to view]
technically it should be 32767, the upper limit of a 16bit integer.. but
such a number I do think is not "usable" by a human being...
1gb of ram is not very much if the instance is heavy loaded, both in term of
database's size and traffic...
traffic will be of course be previously trapped by the built in Query
Governor Workload (only in MSDE 2000), that will kick in when more the 8
concurrent workloads (or batches) are running, slowing down all executing
runs...
if you add "differential" databases usage that will imply a lot of
contention for memory on SQL Server related memory ... every "query" will
try to load datapages into memory, obviously discarding older ones (it's not
that simple the algorithm used by SQL Server thought), as compiled query
plans use memory as well, and so do "connection objects" and so on...
of course, 1 gb of ram can be enought for "traditional" niches where MSDE
has been used since it's introduction... with "moderated" traffic and the
like...
what is you problem?

Hi Andrea,
I have 1 customer with 5 users, but they brings accounting General ledger to
companies crashes (until their extinction), are 600 companies, they operates
only 5 or 6 at same times, rest are waiting, actually they uses access
mdb's (600 mdb's), but too much corruptions. Its possible have 600 db's in
Sql Server (MSDE)?, i`ll have delay in loading the engine at first time?,
only 5 o 6 db's will be in use at same time
Thanks!
PD. Sorry for my english!

hi Alexander,

:D I can believe you :D

I do think some delay may be noticed at MSDE startup, even if MSDE defaults
setting its databases with "autoclose" property... after that you should be
ok, but each time a check for shrinking is performed (about each 30 minutes)
you could incur in some delay if lots of databases are open and if their
autoshrink option is set...
you'll run into troubles (of course) if using instance management tools
(like Enterprise Manager or mine too) based on SQL-DMO... you should "rest"
with query tools, both graphical or command text based...

[quoted text, click to view]

never had such a number of databases per instances... not granting about
results, but if only a bunch of them is open, you should be able to go...
try giving a try :)
