CHAPTER 10 Adding Optional Functionality to Adaptive Server
Configuration Guide 115
Pre-installation tasks for auditing devices
Determine the location of the raw devices for the sybsecurity, syslogs, and
sysaudits table devices. You will need to provide this information later.
Sybase recommends that you:
• Configure your system with the minimum number of auditing devices you
require—you must configure at least three devices. You can add more
auditing devices later with
sp_addaudittable. For information, see the
Reference Manual.
• Install auditing tables and devices in a one-to-one ratio. Tables that share
the same device will share the same upper threshold limit. These tables
cannot be used sequentially when a device fills up, because they both
reside on the same device.
• Install each auditing table on its own device. This enables you to set up a
smoothly running auditing system with no loss of auditing records. With
two auditing tables, when one fills up, you can switch to the other. With a
third auditing table, if one device fails, the System Security Officer can
install a new threshold procedure that changes the device rotation to skip
the broken device until the device is repaired.
• Make the device larger than the table. When you use only three auditing
tables and devices, the size of the table and the size of the device can be
similar, because you can obtain more auditing capacity by adding more
auditing tables and devices (up to eight). When you are working toward
the upper table and device limit (six to eight), you may want to make the
device considerably larger than the table. Then, you can expand the table
size later towards the upper size of the device when a larger auditing
capacity is desired, and few or no device additions are available.
