Each Resident installed will include a synchronization program called Sync that will be used by the Resident to
join/leave a Neighborhood as well as synchronize the entire Neighborhood that the Resident is part of.
Also, during installation, the main Central Router database called IPLIST will be created in the Resident’s home
volume. Once the Resident has been initiated into the Neighborhood, this database will store records for all
Residents of the neighborhood which include the System name, Volume-Subvolume, IP address and Port number
for the Resident.

2.8.2 CONFIGURATION CONSIDERATIONS
 The tool needed to configure your NRs is called SYNC. This program is installed in the NonStop subvol you
defined for a particular instance of Web ViewPoint. Functions of the SYNC program are:
A. Create Neighborhood
B. Join a Neighborhood
C. Leave a Neighborhood
D. Synchronize
 You can create a new Neighborhood on any Resident that you want in that Neighborhood.
 When you join a Neighborhood when prompted for “Enter the System Name of an existing Resident”, make
sure you input an existing Resident, not the Node Name you are on. Example:
A. On \PROD1 node, I create Neighborhood “WEST”; when this is done PROD1 is automatically a
Resident in Neighborhood “WEST”.
B. If I want the \LA Node to join Neighborhood “WEST”, then I would logon to \LA, run the SYNC
program and input \PROD1 when prompted for an existing System Name.
 File used for storing the NR configuration is:
NonStop – IPLIST
 If you ever change the IP address of a Resident (i.e. NonStop Node) you will need to use the SYNC program to
“Leave Neighborhood” and then use the “Join a Neighborhood” to establish the new IP address in the NR
configuration files. The same goes for changes to the Port number in the Web ViewPoint installation
WVPCONF file.
Consider the following example:
A. Neighborhood TEST1 has NSPROD and YOSPRD defined as Residents.
 NSPROD WVP Instance is running from \NSPROD.$DATA1.WVPTEST1 with unique process names. (Note: IPLIST
in subvol WVPTEST1 has the Neighborhood details.)
 YOSPRD WVP Instance is running from \YOSPRD.$DATA4.WVPTEST1 with unique process names
B. Neighborhood QATST on NSPROD has only NSPROD defined as a Resident.
 NSPROD WVP Instance is running from \NSPROD.$DATA2.WVPQATST with unique process names
