[Zope] Re: Stability probs on Solaris? (Was: [Zope] Trouble installing on Solaris (fwd)) Solaris (fwd))

[Paul Browning]

I thought I'd forward (with Tone's consent) an exchange
that happened off list. We've been having problems in Bristol
with Zope 2.1.6 dying under Solaris 7. (Sorry - no hard info
about this, no obvious pattern.)

The consensus seems to be that things appear to better with 
Zope 2.2 - does anyone else's experience support this?

It's weird - the python 'pystones' benchmark runs half as fast as my 
iMac, but Reportlab (an *excellent* PDF library in Python) runs like 
lightning on our Sun iron.

Our servers are all pretty stable here now. We've upgraded a box to 
Solaris 8 and I've compiled (from src) Zope 2.2.0 on it and it's 
working fine. In fact, I'm using the INSTANCE_HOME, PYTHON_HOME 
environment variables to point to *one* installation of 2.2.0 and 
have 5-6 servers running from that. Very nice.

What I do is
% python w_pcgi.py
and
% python wo_pcgi.py

and this does seem to work - of course, this implies a working Pyton 
setup from src.

I've never tried the ./install script (in fact, I don't think I've 
ever seen it!)

I do know that the LD_LIBRARY_PATH env variable is critical if you're 
using shared libraries (eg MySQL, LDAP etc). My variable is
% printenv  LD_LIBRARY_PATH
/usr/local/lib/:/usr/lib:/usr/local/ssl/lib:/usr/local/lib/mysql

(note the mysql library path too...)
