This procedure assumes that you installed the data service packages.
If you did not install the Sun Cluster HA for Apache Tomcat packages, go to Installing the Sun Cluster HA for Apache Tomcat Packages.
It is assumed that the file system of Apache Tomcat will be mounted as a failover file system.
Prepare the parameter file, which is required by the Sun Cluster HA for Apache Tomcat.
# cd /opt/SUNWsctomcat/bin # cp pfile desired place |
Edit the parameter file pfile and follow the comments within that file. For example:
#!/usr/bin/ksh # # Copyright 2006 Sun Microsystems, Inc. All rights reserved. # Use is subject to license terms. # #ident "@(#)pfile.ksh 1.2 06/03/08 SMI" # Set the Apache Tomcat specific environment variables which the start, stop # and check fuctions will use # # EnvScript Script to set runtime environment for tomcat # User Apache Tomcat User # Basepath Absolute path to Tomcat Home directory i.e. 4.x CATALINA_HOME # or TOMCAT_HOME for 3.x # Host Hostname to test Apache Tomcat # Port Port where Apache Tomcat is configured # TestCmd Apache Tomcat test command # Startwait Sleeping $Startwait seconds aftercompletion of the # start command EnvScript= User= Basepath= Host= Port=8080 TestCmd="get /index.jsp" ReturnString="CATALINA" Startwait=20 |
The following is an example for Apache Tomcat 4.1.24.
EnvScript=/global/mnt1/tomtest/env.ksh User=tomtest Basepath=/global/mnt1/tomtest/jakarta-tomcat-4.1.24 Host=tomcat-lh Port=8080 TestCmd="get /index.jsp" ReturnString="CATALINA" Startwait=20
This example is from an Apache Tomcat 4.1.24 configured as standalone web server with the default start page index.jsp. The start page contains the string CATALINA.
The parameter files need to be available on every node that can host the Apache Tomcat data service. For a failover configuration store them on the shared storage. The parameter files cannot differ for an instance of Apache Tomcat on the various nodes.
Repeat Step 1 for every Apache Tomcat instance you need.
Create and register each required Apache Tomcat component.
# cd /opt/SUNWsctomcat/util # cp sctomcat_config desired place |
Edit the sctomcat_config file and follow the comments within that file. For example:
# # Copyright 2006 Sun Microsystems, Inc. All rights reserved. # Use is subject to license terms. # #ident "@(#)sctomcat_config.ksh 1.2 06/03/08 SMI" # This file will be sourced in by sctomcat_register and the parameters # listed below will be used. # # These parameters can be customized in (key=value) form # # RS - name of the resource for the application # RG - name of the resource group containing RS # PORT - name of the port number # LH - name of the LogicalHostname SC resource # SCALABLE - true for a scalable resource or false for a failover resource # NETWORK - false or true, false for multiple master configurations without # shared address, in this case SCALABLE will be ignored # # PFILE - absolute path to the parameter file for the Tomcat resource # HAS_RS - name of the HAStoragePlus SC resource # (it can be a , separated list for the dependencies) # # The following variables need to be set only if the agent runs in a # local zone # ZONE - the zone name where the Apache Tomcat should run in # Optional # ZONEBT - The resource name which controls the zone. # Optional # PROJECT - A project in the zone, that will be used for this service # specify it if you have an su - in the start stop or probe, # or to define the smf credentials. If the variable is not set, # it will be translated as :default for the smf manifest # Optional RS= RG= PORT= LH= NETWORK=false SCALABLE=false PFILE= HAS_RS= # local zone specific options ZONE= ZONE_BT= PROJECT= |
The following is an example for Apache Tomcat.
RS=tomcat-res RG=tomcat-rg PORT=8080 LH=tomcat-lh SCALABLE=false PFILE=/global/mnt1/pfile NETWORK=true HAS_RS=tomcat-hastplus-res |
After editing sctomcat_config register the resource.
# ksh ./sctomcat_register -f desired place/sctomcat_config |
Repeat Step 9,10, and 11 for each Apache Tomcat instance you need.
Enable each Apache Tomcat resource.
Repeat this step for each Apache Tomcat resource created in the step 10.
# clresource status |
# clresource enable Apache-Tomcat-resource |
