Any user can then run the appropriate administration tool and view information, but SNAplus2 will still prevent

users not in the sna group from modifying, starting, or stopping resources.

3.2 Planning for SNAplus2 Conﬁguration

Before you make any conﬁguration changes it is very important to plan thoroughly. Changes that you make can

cause disruption, not only to the users of your local node but possibly to users all around the network.

You may ﬁnd it useful to draw a diagram of any changes that you are making to the topology of the network. If you

are adding or removing connections to other nodes, draw a picture showing your node and the other nodes. You

can use the Motif administration program to gather conﬁguration information about all of the existing connections

and add that information to your diagram.

When you add new resources to your diagram, it is easy to see whether they duplicate existing ones, or whether

any names clash. Similarly, your diagram can help you decide which resources you need to remove and help you

avoid deleting essential ones.

If you are conﬁguring a Client/Server SNAplus2 system with more than one node, ensure that you include all the

SNAplus2 nodes and their connectivity resources in your diagram.

Once you determine the changes you need to make, you can collect the conﬁguration information that you need.

You can use the task sheets in the online help ﬁles for the Motif administration program, or the planning worksheets

described in Section 3.2.1,

Planning Worksheets, to guide you in collecting conﬁguration information for speciﬁc

SNAplus2 functions.

3.2.1 Planning Worksheets

Before you begin to conﬁgure resources for SNAplus2, gather all of the conﬁguration data for the new resources.

To record all of the information for a particular function or application that you need to support, use the planning

worksheets in Appendix A, Conﬁguration Planning Worksheets.

You will probably need to gather conﬁguration information from several sources, such as network administrators,

host administrators, application programmers, and end users.

If you are trying to connect to another node, the administrator at that node is a key contact. The administrator for

a node can tell you names, addresses and characteristics of all the resources on that node. Often, you will need to

ensure that matching conﬁguration parameters are entered at the local node and the remote node.

3.2.2 Task Sheets

The online help screens in the Motif administration program contain task sheets that provide guidance for speciﬁc

conﬁguration tasks. The task sheets contain pointers to all of the help screens for the dialogs that you will use

to enter the conﬁguration information. You can use these to browse the help and see exactly what data you must

collect.

The task sheets also refer to more detailed help for each of the individual windows and dialogs that you must use

to enter conﬁguration information. Those help screens explain each ﬁeld that you must ﬁll in or select.
