NODE Statement

NODE Statement

The NODE statement defines the TCP/IP host name and port that PowerExchange uses to contact a PowerExchange Listener process.
You can specify up to 128 NODE statements in a DBMOVER configuration file.
Optionally, specify SSL authentication and additional parameters that control TCP/IP buffer sizes and wait times. And optionally, specify the
service_name
parameter to identify a PowerExchange Listener Service.

node_name

node1
Required. Unique, user-defined name for this NODE statement. The name does not need to match the name of the PowerExchange Listener process. To contact the PowerExchange Listener process to which the statement points, enter this name in user interfaces that prompt for the location of the PowerExchange Listener, including the following interfaces:
  • The
    Location
    attribute in a connection definition in the Informatica Developer or PowerCenter Workflow Manager
  • The
    Location
    attribute in a source or target definition in the PowerCenter Designer
  • The
    Location
    field in the PowerExchange Navigator dialog boxes
Default is node1.
TCPIP
Required. Communications protocol. TCPIP is the only valid option.
host_name
Required. TCP/IP host name or IP address for the PowerExchange Listener process that listens on the port specified in the
port
parameter. If the
service_name
parameter is specified,
host_name
is ignored.
{
port
|
2480
}
Required. TCP/IP port on which the PowerExchange Listener process that runs on the system specified in
host_name
listens. Valid values are from 1 through 65535. Default is 2480.
{
send_bufsize
|
65536
}
Optional. Size, in bytes, of the data portion of the TCP/IP send buffer. Valid values are from 1024 through 1048576. Default is 65536.
{
receive_bufsize
|
65536
}
Optional. Size, in bytes, of the data portion of the TCP/IP receive buffer. Valid values are from 1024 through 1048576. Default is 65536.
{
send_size
|
4096
}
Optional. Maximum size, in bytes, of the block of data that PowerExchange sends to TCP/IP at one time. If the data exceeds this size, PowerExchange splits data into multiple blocks until it sends all the data. Valid values are from 512 through 1048576. Default is 4096.
Enter a value that is less than or equal to the TCP/IP send buffer size.
{
receive_size
|
4096
}
Optional. Maximum size, in bytes, of the block of data that PowerExchange processes from TCP/IP in one operation. If the data exceeds this size, PowerExchange splits data into multiple blocks until it receives all the data. Valid values are from 512 through 1048576. Default is 4096.
Enter a value that is greater than or equal to the TCP/IP receive buffer size.
receive_timeout
Optional. Number of seconds that PowerExchange uses as the receive timeout value when a long wait is required. PowerExchange uses this value for this request only. Valid values are from 1 through 14400.
{SSL|ZOSSSL}
Optional. Specifies that PowerExchange uses SSL authentication.
Specify the ZOSSSL option only on a Linux, UNIX, or Windows SSL client that is communicating with a z/OS system. Otherwise, specify the SSL option on the Linux, UNIX, or Windows SSL client.
service_name
Optional. To configure an Informatica client tool or integration service to locate a PowerExchange Listener Service in the Informatica domain, specify the name of the Listener Service in the
service_name
parameter.
A client tool is the Developer tool or PowerCenter Client. An integration service is the PowerCenter Integration Service or Data Integration Service.
If you include this parameter, the Informatica client tool or integration service ignores the
host_name
parameter on the NODE statement and uses the
service_name
and
port
parameters to locate the Listener Service in the Informatica domain.
For more information about the PowerExchange Listener Service, see the
Informatica Application Service Guide
