Operating OnLine 3-5
In This Chapter
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, “Things to Avoid,” attempts to safeguard you from
bad ideas that sound good.
You start up and shut down OnLine by changing the mode. The first section,
“Changing Modes,” 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,
“Logical Log Administration.”
At the heart of archive administration is the archive schedule. The third
section, “Archive Administration,” 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, “Monitor OnLine Activity,” groups available information under 19
general topics listed on page 3-61. For each topic, you are provided with
descriptions of the available information, instructions for how to obtain it,
and suggestions for its use.
