to distribute the work of the standby servers. Figure 1–19
illustrates this use of standbys with distributed partitioning.
As shown in Figure 1–19, the Server application on backend A
is the primary server for accounts 1 to 19,999 and the Server
application on backend B is the standby for these same accounts,
shown as a dashed line. The Server application on backend B
is the primary for accounts 20,000 to 39,999 and the Server
application on backend A can be the standby for these same
accounts (not shown in the figure). For clarity, account numbers
are shown only for the primary servers and one standby server.
