| changes to the file in either domain while the LAN connection is broken. |
| Changes can still be made to the configuration of individual nodes. |
| SNAplus2 stores information about the master server and backup |
| |
| servers in the file sna.net, known as the SNA network data file. The |
| master copy of this file is stored on the master server; any changes made |
| to it are automatically copied to all other servers in the same way that |
| changes to the domain configuration file are copied to backup servers. |
| You cannot edit the contents of the SNA network data file directly; |
| instead, SNAplus2 provides administration facilities to access the file. |
| (You can edit node configuration files directly when SNAplus2 is not |
| running; but in general you should use SNAplus2 administration |
| facilities to ensure that all configuration information is valid and |
| internally consistent.) |

For UNIX | A client computer does not contain a configuration file or SNA network |
| data file. Instead, the client has a client network data file that holds the |
| information it needs to access servers on the SNAplus2 LAN. The client |
| relies on a server to provide the necessary configuration information. |
| Most of the details of using |
| those for a server, except that the client has no node resources to define |
| and manage. The following references provide more details about using a |
| client: |
| • To start and stop the SNAplus2 software, see Chapter 3, |
| |
| • To set up information required to support invokable TPs on the client, |
| see “Defining TPs”. |
| • To manage the SNA network information required to access servers |
| on the SNAplus2 LAN, see Chapter 11, “Managing SNAplus2 |
| Clients,” or refer to the |
| Reference. |

| “Diagnostic Tools”, or for more detailed information, refer to the |
