Operating OnLine

Occasionally, administrators conceive of a shortcut that seems like a good
idea. Because of the complexity of OnLine, an idea that appears to be an
efficient time-saver can create problems elsewhere during operation. The last
section in this chapter,

 attempts to safeguard you from

bad ideas that sound good.

You start up and shut down OnLine by changing the mode. The first section,

describes each OnLine mode and how to move OnLine

from one mode to another.

Logical log administration is required even if none of your databases use
transaction logging. Half of logical log administration is configuration; the
other half is backing up the logical log files.

Instructions for modifying the logical log configuration, and for creating and
maintaining the logical log backup tapes, are provided in the second section,

At the heart of archive administration is the archive schedule. The third
section,

provides you with advice and guidelines

for scheduling and coordinating archive activity with other tasks. Archive
administration also includes your configuration decisions regarding the
archive tape device. Creating and maintaining the archive tapes is the third
major topic covered in this section.

OnLine design enables you to monitor every aspect of operation. The next
section,

 groups available information under 19

general topics listed on

. For each topic, you are provided with

descriptions of the available information, instructions for how to obtain it,
and suggestions for its use.
