Dick - have you profiled the amount of memory that JRUN is
consuming when
you're in "crippled" mode. Have you tried
installing seefusion or
fusionreactor to inspect the performance?

Subject: [Commonspot] Dual-server Shared-database
Configuration Advice
Needed
This is probably not something to try to thrash out on the
list, so do feel
free to respond directly.
If you are, or can identify someone who is likely to be, a
good source of
advice, or if you have experienced a similar situation, we
would be
delighted to hear from you.
Our situation is summarized below:
We are running CommonSpot 4.6 SP 1, serving perhaps 87
million hits a month.
We are using VMware for both Windows CommonSpot servers, the
authoring and
the read-only server, with Oracle on a separate, shared
database server.
We have 302 content contributors who maintain 20,770
templates, pages, and
documents (13,000 of them public), on a single site, in 316
top-level
subsites and another 1,588 sub-subsites at various depths.
We are trying to diagnose and cure an intermittent problem:
when we
re-start our read-only server (being on Windows, this should
happen at least
once a month) we observe highly variable performance. If we
measure the
number of pages per second that can be achieved accessing
our standard page,
fetching only the HTML, none of the referenced images, the
results range
from 4 to 30, or more. When it is in the crippled mode, it
is not capable
of serving the actual workload on the site. If we re-start
it, repeatedly,
then usually after a few tries it will come up working
properly. We have
not observed any such variability in performance for our
authoring server.
We do not understand why the read-only server exhibits such
variability, nor
what we should do to make it more predictable.
