Universal Data Mover Server: Network Options - Data Transfer

Field

Description

Compression Options

Compress Data
When this option is selected, the IP address or alias of a local interface may be specified that will be used for all outbound TCP/IP connections established by UDM Server.
If this option is not selected, any available local interface will be used.
 
Enable maximum compression
Select this option to use the zlib compression algorithm, which usually results in a very high compression rate. When this option is not selected, the hasp compression algorithm will be used. This algorithm is not as CPU-intensive as the zlib algorithm, but the resulting data is a little less compressed.

Send Receive Buffer Sizes

Set Default send buffer size to
When this option is selected, a value may be specified that overrides the default size of the application buffer used to send data across a network connection.
A buffer size of 0 (zero) is saved when this option is left un-selected. UDM will then manage the size of the buffers itself based on internal limits.
Exercise caution when changing this option, as it could have a significant performance impact. See the send_buffer_size configuration option in the UDM Reference Manual for more information.
 
Set Default receive buffer size to
When this option is selected, a value may be specified that overrides the default size of the application buffer used to retreive data from a network connection.
A buffer size of 0 (zero) is saved when this option is left un-selected. UDM will then manage the size of the buffers itself based on internal limits.
Exercise caution when changing this option, as it could have a significant performance impact. See the recv_buffer_size configuration option in the UDM Reference Manual for more information.

Universal Data Mover Server: Network Options - Fault Tolerance

Field

Description

Network Fault Tolerance

Network delay
The number of seconds that can be attributed to network latency for any transmission of data among Universal components. This value is automatically added to any network operation where a time out condition is possible and needs to be handled.
 
Retry count
The maximum number of reconnects that will be attempted if a network connection is lost.
 
Retry Interval
The number of seconds between each reconnect attempt.
 
Frame interval
The frame interval is the number of transmission blocks between synchronization points.

Universal Data Mover Server: Network Options - Advanced TCP/IP Options

Field

Description

Override the default TCP receive buffer and set to:

Specifies the TCP receive buffer size for TCP socket connections established from the UDM primary server to the UDM secondary server. The option has no effect for UDM two party transfers. The UDM manager and Universal Broker configuration affects UDM two party transfers.
 
Refer to the Universal Broker tcp_recv_buffer option to set the TCP receive buffer for the other end of the socket connection. The socket TCP buffer is used by TCP to determine the size of the TCP window it advertises to the sending TCP. If both TCP implemenations support window scaling (as defined in RFC 1323), buffer sizes greater then 65535 will be used for the TCP window size. Note that both the sending and receiving TCP implemenations must support window scaling for it to be used in the TCP connection.
 
Adjusting the TCP receive buffer size may improve bulk data transfer performance for certain types of transmission links when transfering data from the UDM secondary server to the UDM primary server. The format of the value is nnnnb, where 'nnnn' is a numeric value and 'b' is one of the following optional unit specifiers:

  • b - bytes (the default, used if no unit is specified)
  • k - kilobytes, where 1 kb = 1024 bytes
  • m - megabytes, where 1 mb = 1048576 bytes
  • g - gigabytes, where 1 gb = 1076761824 bytes

Note that the maximum allowable value for this option is 1076725440 bytes, which can be requested using a value of 1g.

Override the default TCP send buffer and set to

Specifies the TCP send buffer size for TCP socket connections established from the UDM primary server to the UDM secondary server. The option has no effect for UDM two party transfers. The UDM manager and Universal Broker configuration affects UDM two party transfers.
 
Refer to the Universal Broker tcp_send_buffer option to set the TCP send buffer for the other end of the socket connection.

  • m - megabytes, where 1 mb = 1048576 bytes
  • g - gigabytes, where 1 gb = 1076761824 bytes

Note that the maximum allowable value for this option is 1076725440 bytes, which can be requested using a value of 1g.

Disable TCP packet coalescing

Select this option to disable the TCP packet coalescing algorithm (that is, Nagle algorithm). When this option is unchecked, the default TCP implementation is used, which may or may not disable the algorithm.
 
Exercise caution when changing this option, as it could have a significant performance impact. See the tcp_no_delay configuration option in the UDM Reference Manual for more information.
 
This option is checked by default.

Universal Data Mover Server: SSL/TLS Protocol Options

Field

Description

Data Session SSL cipher List

Universal Data Mover Server uses the SSL/TLS protocol for transmission of data across the network. A data session is established within the application that provides the connections necessary for the transfer of data to take place. The SSL/TLS cipher suites available for communication across the data session are listed here.
 
The Server will compare the Manager's cipher list to its own list of ciphers. The result of the comparison will be an agreed-upon cipher used for communication over the data session. Use the up/down arrows on the right to sort the list and establish a priority for the selected ciphers. The first one in the list that is accepted by the Server will be the one used.
 
The following cipher suites are available:

  • RC4-SHA -- 128-bit RC4 encryption, SHA-1 message digest
  • RC4-MD5 -- 128-bit RC4 encryption, MD5 message digest
  • AES256-SHA -- 256-bit AES encryption, SHA-1 message digest
  • AES128-SHA -- 128-bit AES encryption, SHA-1 message digest
  • DES-CBC3-SHA -- 128-bit Triple-DES encryption, SHA-1 message digest
  • DES-CBC-SHA -- 128-bit DES encryption, SHA-1 message digest
  • NULL-SHA -- No encryption, SHA-1 message digest
  • NULL-MD5 -- No encryption, MD5 message digest
  • NULL-NULL -- Disables the SSL/TLS protocol

Require and encrypted control session

Select this option to require encryption over the control session between the UDM Manager and Server. When this option is selected, the UDM Server will not accept a control session SSL/TLS cipher of NULL-NULL from the remote UDM Manager.
When this option is not selected, the UDM Server will accept any control session cipher from the UDM Manager, even one that disables SSL/TLS encryption.
This option is checked by default.

Universal Data Mover Server: Event Subsystem Options

Field

Description

Event Generation Options

Generate activity monitoring events
When this option is selected, the Universal Data Mover Serve will generate events that monitor product activity. This option is selected by default.
 
Persistent event list
Specifies which events are to be generated and processed as persistent events. A persistent event is saved in a Universal Enterprise Controller (UEC) event database for long-term storage.
 
Enter a list and/or range of numeric event types, separated by a comma. To exclude an event or range of events, precede the entry with an upper- or lower-case 'X'. Use an asterisk * to specify all event types.
 
For example:

  • x*
    Do not generate any events (this is the default)
  • *
    Generate all event types
  • 100
    Generate all event types except 100
  • 100,200-205
    Generate event type 100 and 200 through 205
  • 100,200-205,x202
    Generate event types 100 and 200 thru 205, excluding event type 202

Entries are processed from left to right, and the list is order dependent. For example, an entry of x*,100 prevents generation of all event types except 100, while an entry of 100,x* prevents generation of all event types (the right-most entry takes precedence).
