When it moves to redolog2.log, it will initialize
that file with a sequence number of 5.
Remember that the operating system uses the redo log file to identify the physical
file, while Oracle uses the redo log file sequence number to determine the order in
which the logs were filled and cycled. Because Oracle automatically reuses redo log
files, the name of the redo log file is not necessarily indicative of its place in the redo
log file sequence.
Figure 2-6 illustrates the filling and cycling of redo logs.

that capture the purpose and some critical details about the nature of the file.

Figure 2-6:
redog1m1.log, redog1m2.log, .
