How to create 2 OVSD application server instances?

Hi all,

could anyone help me to create 2 independent instances of OVSD 4.5 SP19 application servers on one machine? I'd like to use one for end users and second for integrations purposes only.

Thanks,

Milan K.

HI here it is

these info are available under chapter 7 in Administrator Guide:

Starting Multiple Servers
In a multiple server environment, when a client connects to an
application server, a list of all application servers that are currently
running is sent to the client and stored in the file srv.dat in the user
profile. When the application server that the client is connected to fails,
the next server on the list takes over.
However, if, at the moment the client connects to the application server,
there is only one server running, and afterwards more servers are
started, the client will not know about the other servers. Thus, if the
clientsâ server fails, no take-over will take place. This happen because
the list is only sent to the client when it first connects at the start of a
session. It is therefore recommended to start all your Service Desk
application servers in the multiple server environment before clients
start to connect.
When this happens, the client can be "manually" connected to another
application server by changing the hp OpenView service desk Server
name field in the account properties dialog box.
Service Desk Port Allocation
Communication between servers and client computers takes place via
TCP/IP ports.
The Service Desk application server listens by default on port 30999 for
incoming connections from Service Desk clients. The port number can be
changed by modifying the ITP port value in the server configuration file
server_settings.xml. If the port specified does not match the default
30999, then all clients will need to specify the correct port number when
they connect to the application server.
To change the port number used by clients:
1. From the Start menu on the client, select Program Files and then hp
OpenView service desk 4.5.
2. Select client and then client accounts. The hp OpenView service desk
Accounts dialog box is displayed.
3. Select the Service Desk account being used by the client and click
Modify. The account Properties dialog box is displayed.
4. In the hp OpenView Service Desk Server name field add the port
number after a colon. For example, myappserver:12345, where 12345
is the new port number.
The Service Desk application server listens by default on port 30980 for
incoming HTTP Post requests from the SD_event program. The port
number can be changed by modifying the HTTP port value in the server
configuration file server_settings.xml. If you change the default port
number, SD_event needs to be told to use the new value. SD_event can
use another port number by specifying the port number on the command
line with the -p flag or by specifying a port entry in the SD_event
configuration file.
The application server uses by default port 25 for SMTP connections.
The port number can be changed by modifying the value in the server
configuration file server_settings.xml.
The client listens by default on ports 30999-31019 for incoming requests
from the application server.
The Service Desk Agent listens by default on port number 50998 for
incoming requests from the Service Desk application server. The value of
this port number cannot be changed. Communication between Service
desk application servers and the database server also takes place via
TCP/IP ports. If an Oracle database is used then the protocol is Oracle
Net. Oracle Net uses port 1521. If a Microsoft SQL Server database is
used the protocol is Tabular Data Stream. Tabular Data Stream uses
port 1433. When running in a firewall environment, all network traffic
destined for port numbers listed above must be able to pass the firewall.
Stopping Servers not Allocated Default Port
If you have multiple servers running, or an application server running,
on a port other than the default port (30999), sd_servermanager should
be used to select and stop the server(s).
Multiple Server Instances
Multiple instances of the Service Desk application server can be run on
one machine, providing it has sufficient capacity. These server instances
can be started by creating copies of the server configuration file
server_settings.xml and starting separate instances of the
application server using the different settings files. This can be achieved
by running the start server batch file multiple times from the command
line.
NOTE The ITP default port number must also be changed when creating a
configuration profile for a new instance.
Like multiple servers on different machines, you may want to use
multiple instances for dedicated purposes.


Starting Multiple Instances on Windows NT or 2000
This procedure assumes you have installed and configured a Service
Desk application server on the computer where you want to run multiple
instances.
To run multiple instances:
1. Make a copy of the \server\server_settings.xml file of the
installed server and place it in a different folder.
2. Run the server settings editor, this will open the original
server_settings.xml for editing.
3. Use the editor to create a configuration profile for the new instance
that you want to run. Click OK to save the modifications.
NOTE Use a text editor to edit the xml file, if you want to add specific
modifications that are not available in the server settings editor.
4. Navigate to the server folder and rename the
server_settings.xml file to identify it.
5. Using the command prompt in the server\bin folder, run this
command: sd_server.bat start â /settings=â .
6. Repeat this process for any extra server instances you require.
7. Copy the unedited server_settings.xml back to its original
location.
