Adding an Application
and Terminal to a
Second System
In this, the second part of the example, a Pathway application process and a terminal
LU, both residing on a second Tandem system, are added to the configuration. As
Figure 3-2 illustrates, this system, called \SYS2, communicates with \SYS1 through an
Expand link. The PATHMON process on \SYS2 is named $PATHY. Note that LUNS
will be running on both systems.
The new Pathway process residing on \SYS2 is called INVENTORY, and the new
terminal is designated LU5. This portion of the example is implemented through the
following operations:
1. SNAXUTL is used to create an ESS table on \SYS2.
2. An active SET table is created for \SYS2 through the following operations:
a. SNAXUTL is used to allocate space for the table and to place within it a record
for the new ESS table.
b. The SCF ALTER SUBSYS $SSCP command is used to designate it as the active
SET table for \SYS2.
3. SCF is used on \SYS2 to:
a. ADD LU5
b. ADD the Tandem Creator process as an APPL
c. ADD SNAXUTL as an APPL on \SYS2
4. SNAXUTL is used to update the ESS table on \SYS1.
