You must have a connector JAR file for your MySQL, Microsoft SQL Server or Oracle database.

When installing Zephyr on your nodes, keep in mind the following:

• Install Zephyr on any drive other than drive C: to avoid permission issues, as administrator permissions may be required to work with this drive.

• Use the same Zephyr version and build on all the nodes.

• Zephyr installed on all the nodes must have the same license.

Follow the installation steps for Windows described in the Installing Zephyr Server section.

Open Command Prompt as an Admin and run the following command:

zephyr_6.6_xxx_setup_iRev_xxx.exe  -VzSkipStartupData=true

Open the terminal and run the following command:

sh zephyr_6.6_xxx_setup_iRev_xxx.sh  -VzSkipStartupData=true

Write down the IP of each node – you will need them at step 7. 

In the file, find the following line:

<Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"/>

and replace it with the following:

<Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"channelSendOptions="8">
<Manager className="org.apache.catalina.ha.session.DeltaManager"
expireSessionsOnShutdown="false"
notifyListenersOnReplication="true"/>

<Membership className="org.apache.catalina.tribes.membership.McastService"
address="228.0.0.22"
port="45564"
frequency="500"
dropTime="3000"/>
<Receiver className="org.apache.catalina.tribes.transport.nio.NioReceiver"
address="auto"
port="4000"

<Interceptor className="org.apache.catalina.tribes.group.interceptors.TcpFailureDetector"/>
<Interceptor className="org.apache.catalina.tribes.group.interceptors.MessageDispatch15Interceptor"/>
</Channel>
<Valve className="org.apache.catalina.ha.tcp.ReplicationValve"

<Valve className="org.apache.catalina.ha.session.JvmRouteBinderValve"/>
<Deployer className="org.apache.catalina.ha.deploy.FarmWarDeployer"
tempDir="/tmp/war-temp/"
deployDir="/tmp/war-deploy/"
watchDir="/tmp/war-listen/"
watchEnabled="false"/>
<ClusterListener className="org.apache.catalina.ha.session.ClusterSessionListener"/>
</Cluster>

1. Find the line –

<member>127.0.0.1:5701</member>

– and add the IPs of all the nodes instead of 127.0.0.1. For example:

<member>172.17.18.141:5701</member>
<member>172.17.18.157:5701</member>
<member>172.17.18.223:5701</member>
<member>172.17.18.201:5701</member>

2. Find the line –

interface>127.0.0.1</interface>

– and replace it with an IP address that has an asterisk instead of the last component. For example:

<interface>172.17.18.*</interface>

<interface>172.17.18.*</interface>

Find the line –

<input type="hidden" id="notificationConType" value="websocket" />

– and replace websocket with sse:

<input type="hidden" id="notificationConType" value="sse" />

In the file, before the web-app tag, add the tag <distributable />:

#unique identifier for the cluster node
cluster.aws.enable=false
HAZELCAST_PASSWORD=huser

cluster.key=node1 (this should be a unique name of the node)

The cluster.key name must be unique in each file.

Share a folder by using NAS (network-attached storage) or a similar device:

1. Create a shared folder with read/write access in NAS.

2. On all the nodes, open the

Program Files\Zephyr\tomcat\webapps\flex\WEB-INF\classes\jdbc.properties file, find the line

ZEPHYR_DATA = C:/Program Files/Zephyr/zephyrdata

and replace the C:/Program Files/Zephyr part with the IP address of the NAS shared folder. For example:

ZEPHYR_DATA= //192.168.11.141/zephyrdata

Install the NFS (Network File System) server and client on CentOS 7. To do that:

On the server side:

1. Install the required NFS packages by running the following command:

 yum install nfs-utils

 2. Create the Zephyrdata directory and allow access to it:

chmod -R 777 /homeZephyrdata

3. Start the following services and add them to the Boot Menu:

systemctl enable rpcbind
systemctl enable nfs-server
systemctl enable nfs-lock
systemctl enable nfs-idmap
systemctl start rpcbind
systemctl start nfs-server
systemctl start nfs-lock
systemctl start nfs-idmap

4. Open exports for editing –

sudo gedit /etc/exports

– and type the following:

/home/zephyrdata 192.168.0.101(rw,sync,no_root_squash,no_all_squash)
/home/zephyrdata 192.168.0.102(rw,sync,no_root_squash,no_all_squash)

5. Start the NFS service by running the following command:

 systemctl restart nfs-server

 6. Add the NFS service override in the CentOS 7.0 firewall-cmd public zone service:

firewall-cmd --permanent --zone=public --add-service=nfs
firewall-cmd –reload

The NFS server is ready to work.

On the client side:

1. Install the required NFS packages by running the following command:

yum install nfs-utils

2. Start the following services and add them to the Boot Menu:

systemctl enable rpcbind
systemctl enable nfs-server
systemctl enable nfs-lock
systemctl enable nfs-idmap
systemctl start rpcbind
systemctl start nfs-server
systemctl start nfs-lock
systemctl start nfs-idmap

3. Mount the NFS share on the client machine by running the command below:

mount -t nfs 192.168.0.100:/home/zephyrdata  /home/node1/zephyrdata

4. Change the ZEPHYR_DATA path to the mounted path for all the nodes in the

opt\Zephyr\tomcat\webapps\flex\WEB-INF\classes\jdbc.propeties file.

For example:

ZEPHYR_DATA = /home/node1/zephyrdata

5. You are connected to the NFS share. Now you can crosscheck it by running the following command:

df -kh
