OVNPM 1.5.2 - Performance Agent for NonStop Server Management Guide

Managing Distributed Servers 67
9-3-2 DSV (Display Agent) Installation Requirements
1. Before installing DSV distributed server, each node to be monitored must have the OVNPM product
installed and be part of an EXPAND Network.
NOTE: OVNPM is operational after each single installation. A user can gain access to OVNPM by connecting
to a local node to retrieve associated OVNPM data.
2. The user needs to selects one of the EXPAND linked Nodes on which to install the DSV server. Only one
DSV server is required per EXPAND network.
3. Remote Passwords between DSV nodes and other nodes must be set.
4. Expand security must allow OVNPM processes to open each other over the EXPAND network.
9-3-3 DSV Installation and Management
The VCONF utility must be used to configure DSV.
VCONF Option 3, Configure Distributed Servers generates the following data:
• DSV environment, which includes the name, CPU and priority of DSV processes. This information is
saved in the file DSVENV in the OVPMTACL subvolume.
• DSV configuration, which consists of the list of nodes. This information is saved in the file DSVCFG in
the OVPMCFG subvolume.
There are two OVNPM TACL Macros available for Managing (Start/Stop) the DSV Server.
• SV_START DSV <OVNPM TACL Macro – Starts Distributed Server Environment
• SV_STOP DSV <OVNPM TACL Macro – Stop Distributed Server Environment
9-3-4 DSV Configuration file
The DSVCFG configuration file contains a description of the nodes to connect to the DSV server. DSVCFG is
located in the OVNPM configuration subvolume.
The VCONF utility prompts for a logical name for the distributed environment. The Display Agent uses this
name to refer to the group of nodes. You can enter any name, up to 10 characters, such as your company name.
The VCONF utility then scans for all EXPAND linked nodes to detect each remote Display Server. It uses the
local Display Server process name to detect all remote Display Servers with the same name and then includes
these detected nodes in the DSV configuration. If the Display Servers on the remote nodes do not all have the
same name, edit the DSVCFG file to configure the additional remote Display Servers with different names.
9-3-5 Generating the DSV Environment
The macro VCONF utility creates and save the DSV environment in file DSVENV that is located in OVNPM TACL
subvolume. This file is read by the macro VISLOAD that loads the DSV environment.
The DSV environment contains the following features of DSV processes:
• DSV server
• TCP/IP server
9-3-6 DSV Installation Procedure
Step 1: Start the DSV installation procedure using the following command.
TACL> VOLUME <$Install>.OVPMTACL
Step 2: Run the following command to load all the OVNM TACL macros.
TACL> RUN VISLOAD
Step 3: Run the VCONF utility and select option 3, Configure Distributed Server option to install the DSV server
and discover all the EXPAND nodes having OVNPM installed.
