Configuring default port for Communications Manager

The Communications Manager is configured to use port 20032 to open TCP sockets on a client. If this port is in use by any other application, the NetVault Service fails immediately after startup. When this error occurs, you must change the default port for Communications Manager.

Use the following procedure to change the default port on the NetVault Server and all clients.

To change the default port for Communications Manager:
1
Open the file configure.cfg in a text editor. You can find this file in the config directory under the NetVault installation directory.
2
In the [machine] section, append the following line:
[machine]
Comms TcpPort=<port number>
Verify that the port is not in use by any other application. In a firewall-protected environment, make sure that the port is open and specified in the firewall settings for the client.
3
Save the file.
4
Restart the NetVault Service to apply the new settings.

Configuring Process Manager settings

This section includes the following topics:

About Process Manager
•
Configuring shared memory settings

About Process Manager

The Process Manager (nvpmgr) runs on all NetVault machines.

This process manages all other NetVault processes. It creates and destroys the transient processes. The Process Manager also manages the allocation of the shared memory area for the process table and trace buffers.

You can modify the Process Manager settings from the Change Settings page.

 
* 
NOTE: You must restart the NetVault Service to apply any changes to the Process Manager settings.

Configuring shared memory settings

To configure shared memory settings for Process Manager:
1
In the Navigation pane, click Change Settings.
2
On the NetVault Server Settings page, complete one of the following actions:
•
To configure default settings for the NetVault Server, continue to Step 3.
•
To configure default settings for a NetVault Client, click Choose machine. In the Choose machine drawer, select the client, and click Go to settings.
•
Under Services, click Process Manager.
3
In the Process Manager dialog box, configure the following settings.
 
Table 131. Shared memory settings for Process Manager
Setting
Description

Shared Memory Allocated to the Trace Buffer of Each Process

This setting controls the amount of shared memory allocated to the individual trace buffers of each NetVault process.

•
The default value is 31KB on all platforms.
•
The minimum value is 1KB on all platforms.
•
The maximum value is 32KB on all platforms.

To increase the shared memory for individual trace buffers, type or select a new value. The shared memory is allocated in KB.

NOTE: Increasing the value of this setting could affect the performance and scalability of NetVault. For example, it could reduce the maximum number of concurrent data transfers.

Shared Memory Used for Process Table

This setting controls the amount of shared memory allocated to the Process Table that maintains the details of all current NetVault processes.

•
The default value for server and client is 16384KB and 3864KB respectively on all platforms.
•
The minimum value is 2000KB on Windows and 500KB on Linux and UNIX.
•
The maximum value is 128000KB on all platforms.

On NetVault machines running a number for concurrent processes, you can increase the amount of shared memory for the Process Table to get optimum performance. To increase the shared memory, type or select a new value. The shared memory is allocated in KB.

On Windows, the shared memory is allocated dynamically.

On Linux and UNIX, the shared memory for process table is allocated from the shared memory pool. To increase the shared memory for process table on these platforms, you must first increase the overall shared memory pool. You can increase the shared memory by configuring the shmmax variable in the system configuration file. For more information about increasing the shared memory pool, consult the relevant O/S documentation.
