SNAX/XF LU Network Services Manual

2 Using LUNS
097841 Tandem Computers Incorporated 2–1
Before LUNS can become fully operational, you must:
1. Plan the overall configuration.
2. Build the SET table, ESS tables, and BIND table with SNAXUTL.
3. Use SCF to START $SSCP.
4. Use the SCF ADD APPL command to identify the Tandem Creator process and the
TACL process to LUNS.
5. Use the SCF ADD APPL command to identify SNAXUTL to LUNS if you want the
ability to modify ESS tables dynamically.
6. ADD and START all lines, Physical Units (PUs), and Logical Units (LUs) in your
network.
7. Run the Tandem Creator process.
8. Start the Pathway environment if terminals will be logging on to Pathway
applications.
Each of the following subsections presents information you need to perform these
tasks. Together, they provide information about options, requirements, and
limitations that apply to any LUNS implementation.
Using This Section In the following discussion of LUNS configuration tables, note the following:
The object of the SNAXUTL ADD ESSCMD command is called the “command-
name field.”
The object of the SNAXUTL ADD ESSMSG command is called the “message-name
field.”
(In Section 1, “Introduction to LUNS,” the command-name field and the message-
name field were included in the generic term “record-name field,” since both types of
fields denote the name of a record within an ESS table.)
The various other fields in a given record are referred to by the SNAXUTL operand
names (keywords) used to create them. For example, the field that specifies a terminal
protocol is called the PROTOCOL field; the field that specifies a subdevice or SNA
name is called the PLUNAME field; the field that specifies concatenated data is called
the CONCDATA field, and so on.
