SNA Node Operations
SNA Node Operations enable you to display information and manage
the node for certain Personal Communications resources, which can be useful when operating
the SNA node. The following tasks are supported:
- Starting and stopping resources
- Deleting resources
- Displaying resource information
- Changing session limits
- Initiating path switches
The configuration information for an SNA Node is stored in an ASCII file, with the extension .ACG. You can edit the file by launching SNA Node Configuration. To ensure that your new configuration is correct, use the Verification tool.
You can display information or take action on resources if you start 3270, 5250, or any client/server sessions with one of the following attachment types:

SNA resources that can be displayed or managed include the following:
- Connection Networks
- Allows APPN nodes in a LAN to have direct links with each other without requiring logical link definitions at each node.
- Connections
- Link stations to the adjacent nodes.
- CPI-C Side Information
- Associate a set of parameters with a specified symbolic destination name.
- Data Link Controls
- How data is formatted for transmission on the physical connection.
- Devices
- Parts of the workstation hardware, such as adapters, that are used to transmit and receive data.
- DLUR PUs
- A dependent logical unit requester (DLUR) physical unit (PU) is a PU in an APPN end node that owns dependent LUs, but requests that a dependent LU server provide the SSCP services for those dependent LUs.
- Focal Points
- A system that provides centralized network management services.
- Local LU 0 to 3
- A local logical unit (LU) type 0, 1, 2, or 3 is a dependent LU on the workstation that provides services for 3270 terminal and printer emulation applications.
- Local LU 6.2
- A local logical unit (LU) type 6.2 is an independent or dependent LU that provides APPC services.
- LU 6.2 Sessions
- Transports data between two partner LU 6.2s. Conversations between transaction programs use LU 6.2 sessions.
- Mode
- The name used by the initiator of a session to designate the characteristics desired for the session, such as traffic pacing values, message-length limits, sync point and cryptography options, and the class of service (COS) within the transport network.
- Node
- The control point that manages the node and its associated resources. The local node provides APPN services.
- Partner LU 6.2
- A remote computer that communicates through an APPC session with local LU 6.2s.
- RTP Connections
- In high-performance routing (HPR), a rapid transport protocol (RTP) connection is the connection established between the endpoints of the route to transport session traffic.
- Transaction Programs
- A transaction program (TP) is a program that processes transactions in an SNA network. There are two kinds of TPs: application transaction programs and service transaction programs.
