HP Serviceguard Enterprise Cluster Master Toolkit User Guide (5900-2145, April 2013)

6. Copy all files from "/opt/hpws22/tomcat/conf" to "/shared/tomcat_1/conf"
7. Create a directory "logs" under the "/shared/tomcat_1/".
8. Update the Tomcat configuration files present in "/shared/tomcat_1/conf" directory and
change the Tomcat instance configurations to suit your requirement.
Using VxVM
To configure a shared file system which is managed by VxVM, create disk groups and logical
volumes on the shared disks and construct a new file system for each logical volume for the Tomcat
Web applications (and CATALINA_BASE).
The following is an example of configuring Tomcat instance using VxVM:
1. Create a Disk Group "DG_00" on the shared storage.
2. Create Logical volume "LV_00" on the Disk Group "DG_00".
3. Construct a new file system on the Logical Volume "LV_00".
4. Create a directory "/shared/tomcat_1" on a local disk. Repeat this step on all nodes configured
to run the package.
5. Mount device "/dev/vx/dsk/DG_00/LV_00" on "/shared/tomcat_1".
Configure multiple Tomcat instances in the cluster using the same method. For more information
on creating volumes and logical volumes, see the latest Managing Serviceguard manual available
at http://www.hp.com/go/hpux-serviceguard-docs —>HP Serviceguard .
Methods to configure the Tomcat binaries in a shared file system
As discussed earlier, in a shared configuration, you can place the Tomcat binaries in a shared file
system. This can be configured using two methods:
To create a shared configuration for the Tomcat Server on the shared file system mounted at
/mnt/tomcat:
• Method 1
1. Create the shared storage to store the Tomcat files for all nodes configured to run the Tomcat
package. After the storage is configured, create the mount point for that shared storage on
these nodes. For this example, the mount point is "/mnt/tomcat".
2. Copy all files from /opt/hpws22/tomcat to /mnt/tomcat on any one node.
3. Remove or rename /opt/hpws22/tomcat on all nodes configured to run the Tomcat
package.
4. Create a symbolic link between /opt/hpws22/tomcat and /mnt/tomcat on all nodes
configured to run the package.
• Method 2
1. Create the shared storage to store the Tomcat files for all nodes configured to run the Tomcat
package. After the storage is configured, create the mount point for that shared storage on
these nodes. For this example, the mount point is "/mnt/tomcat".
2. On any one node in the cluster that is configured to run the package, activate the shared
storage and mount it at the mount point "/mnt/tomcat". Copy the Tomcat files to the shared
storage using the altroot.sh utility: $ /opt/hpws22/util/altroot.sh --tomcat /
mnt/tomcat
Besides moving the files in the /opt/hpws22/tomcat directory to the new directory
/mnt/tomcat, copy one additional Tomcat file to all the other nodes in the cluster that are
configured to run the package.
3. On the same node, copy the following file to the other nodes in the cluster that are configured
to run the package:/etc/rc.config.d/hpws22_tomcatconf .
