Russell E Glaue commented on GERONIMO-6270:
-------------------------------------------
Here is a summary of the problems I am aware of in enabling multiple instances:
# SnapshotConfigXMLBuilder: (not reported) - Wants GERONIMO_HOME/var/monitoring
to exist, and will complain if it does not, however, the geronimo instance will
continue to start regardless. If it cannot create the directory, Geronimo will
fail to start with the following error when "Loading agent-car-jmx": ERROR
[SnapshotConfigXMLBuilder] Could not make the directory
/opt/geronimo-tomcat7-javaee6-3.0-SNAPSHOT-20111220/var/monitoring/
# ActiveMQ: GERONIMO-5987 (reported in comment) - ActiveMQ lock directory is
specified relative to the working directory the user starts up the geronimo
instance. Also, if ActiveMQ cannot create var/activemq Geronimo will fail to
start with the following error when "Loading activemq-broker-blueprint": ERROR
[BrokerService] Failed to start ActiveMQ JMS Message Broker. Reason:
java.io.IOException: Failed to create directory 'var/activemq'
# GERONIMO_TMPDIR: GERONIMO-5987 (reported in comment) - The start script sets
the temp directory relative to GERONIMO_HOME, but instead should be set
relative to the Geronimo Instance directory
# Karaf: GERONIMO-6174 - Karaf expects to use
{karaf.home}/etc/shell.init.script each time a shell session is started, but I
think ideally that should be {karaf.base}/etc/shell.init.script
# Repository: GERONIMO-6175 - The repository will use one in
{org.geronimo.server.dir}/repository if configured, but some Geronimo code
still expects a writable repository to exist at GERONIMO_HOME/repository. If it
does not exist, Geronimo will fail to start with the following errors when
"Loading rmi-naming": (1) WARN [RMIRegistryService] RMI Registry failed, (2)
ERROR [GBeanInstanceState] Error while starting; GBean is now in the FAILED
state:
abstractName="org.apache.geronimo.framework/rmi-naming/3.0-beta-1/car?ServiceModule=org.apache.geronimo.framework/rmi-naming/3.0-beta-1/car,j2eeType=GBean,name=RMIRegistry"
To see some of the complaints, the var directory must be removed from
GERONIMO_HOME, and in its place you must create a file named var. This will
prevent Geronimo from creating GERONIMO_HOME/var when it discovers it does not
exist.
Here is the procedure to create two geronimo instances:
# Follow steps in
https://cwiki.apache.org/confluence/display/GMOxDOC30/Running+multiple+Geronimo+instances
# Use the below start script
# create an empty file GERONIMO_HOME/var
# To expose some issues, comment out the work-arounds and restart.
Here is a start script I use to workaround some, but not all, of the issues as
we are able.
{noformat:borderStyle=solid}
#!/bin/bash
# Geronimo Named Instance start script
# instance: gserv1
# Uncomment this to explicitly set Geronimo's runtime Java
#JAVA_HOME=/usr/jdk1.6.0_25
#PATH=${JAVA_HOME}/bin:${PATH}
# Set the location of the Geronimo Installation, and Geronimo Instance
GHOME=/opt/geronimo3
GVIRT=gserv1
GSERV=${GHOME}/${GVIRT}
#
# The Next section works around some known issues
#
# GERONIMO-5987
# Must change to the server directory in order to work around ActiveMQ lock
# file conflict issue reported in GERONIMO-5987.
cd ${GSERV}
# GERONIMO-6174
# Uncomment for the Workaround of issues in GERONIMO-6174
GERONIMO_TMPDIR=${GSERV}/var/temp
GERONIMO_OPTS="${GERONIMO_OPTS} -Dkaraf.home=${GSERV}"
#
# This Section starts the Geronimo Instance
#
export GERONIMO_OPTS="${GERONIMO_OPTS}
-Dorg.apache.geronimo.server.dir=${GSERV}"
export GERONIMO_TMPDIR
export GERONIMO_HOME=${GHOME}
export GERONIMO_SERVER=${GSERV}
#
# Uncomment for Normal startup, and comment out the "Interactive startup"
#${GHOME}/bin/startup

# Interactive startup
