* I think you might be missing an INSTANCE_HOME parameter here, something like
# what we'd like but won't recognize instance home
# exec /usr/bin/python $ZOPE_BASE/z2.py -z $ZOPE_BASE -u $USER \
# -w $HTTP_PORT -f $FTP_PORT -t $THREADS -Z $MANAGER \
# -l $INSTANCE_HOME$ZOPE_LOGFILE \
INSTANCE_HOME=$INSTANCE_HOME \
# -D "$@" $INSTANCE_HOME/var/startup.log &or export the INSTANCE_HOME
* Are you shure you want to start Zope in debug mode?
* You might want to check http://zope.org/Documentation/Books/ZopeBook/2_6Edition/MaintainingZope.stx , I put some (very much simpler) startup scripts there
* Finally, the upcoming Zope 2.7 should behave much better wrt this (if thats any help to you :-))

Hi,
These are probably more shell scripting issues, but I'm hoping that some scripter with an agile mind will show me the error of my ways, so here goes.
I have borrowed a script from the zope site and modified it for my purposes, and it 'sort of' works. The issues are:
Can't seem to get the Instance-Home stuff to work right without local
start scripts in each directory. Right below the $INSTANCE_HOME/start
is the line I'd like to use to simplify the management of the instances.
Can't get stop to work right. First 'stop' is not an instance, then the first instance does appear to get stopped, but it errors on the other two.
I get a 'start0' for the value of $WAIT in the starting text display. (should just be a big fat zero or one!)
And for some reason, the script dumps the entire local environment to the display before it does anything; any ideas why?
All constructive criticism welcome, and I'll take some flames (high of 22 today).
System is RedHat-9.0 Zope-2.6.2 Python-2.2.3
Zope is installed in /usr/local/zope Instances are /var/zope-sites/
Here's the script:
#!/bin/sh
# /etc/init.d/zope-instances
#
# Starts or stops multiple instances of zope one by one or all at ones.
# Configuration is done all through one configuration file # /etc/zope-instances.conf which defines the location of the data-files,
# the user to run the instance, FTP portnrs, number of threads and if
the # zdaemon should be used (to start a new instance should the one crash) # all configurable per instance.
#
# Steps for creating and running a new instance:
# - start with a normal working (fresh) distribution of Zope
# ... snip ...
# - edit /etc/zope-instances.conf to run the new instance as you
desire
# - start the new instance (/etc/init.d/zope-instances start
instance-name)
#
# Note: this script is only tested for Red Hat distributions. # Locations of scripts may vary from various distributions. # Use at own risk.
