RTR Terminology

Figure 1–4 Facility Symbol

VM-0822A-AI

A facility name is mapped to specific physical nodes and their

roles using the CREATE FACILITY command.
Figure 1–5 shows the logical relationship between client

application, server application, frontends (FEs), routers (TRs),

and backends (BEs) in the RTR environment at a specific

location. The database is represented by the cylinder. Two

facilities are shown (indicated by the large double-headed

arrows), the User Accounts Facility and the General Ledger

Facility. The User Accounts Facility uses three nodes, FE, TR,

and BE, while the General Ledger Facility uses only two, TR and

BE in the configuration shown. Its FEs are on nodes not shown

in the figure, at another location.
