Veritas Storage Foundation™ for Oracle 5.0.1 Administrator's Guide

which you plan to create Storage Checkpoints, and how many Storage Checkpoints
you want to retain on your system at any given time.
You can use Storage Checkpoint Capacity Planning to simulate various Storage
Checkpoint creation and retention models in your production environment, collect
the associated file system space usage information based on these models, and
use this information to proactively determine how much additional storage space
is needed for Storage Checkpoints.
Storage Checkpoint Capacity Planning uses the cron command as the underlying
mechanism to run the Capacity Planning schedules you create. You must have
the proper access and permissions to create a cron job, or the Capacity Planning
schedule will fail to run.
All Storage Checkpoint Capacity Planning activity, including the file-level block
change information, is logged into the /etc/vx/vxdba/logs/ckptplan.log log
file.
Starting the Storage Checkpoint Capacity Planning
utility
The Storage Checkpoint Capacity Planning utility operations can be run by the
Oracle Database Administrator (typically, the user ID oracle) of the database
instance.
Before starting the Capacity Planning utility, the following conditions must be
met:
■ You can only use the Storage Checkpoint Capacity Planning utility
in an environment that contains no Storage Checkpoints created
by other tools or products, including VERITAS NetBackup and the
Command line interface using the dbed_ckptcreate command
■ Each time cron attempts to create a Storage Checkpoint at the
time designated in the schedule you create, the Storage Checkpoint
Capacity Planning utility checks for the presence of Storage
Checkpoints created by other tools or products and fails if it detects
any of these other Storage Checkpoints.
