If AUDITDUMP is ON, use the ALTER AUDITDUMP command to modify other
parameters relating to audit dumping. These parameters are explained in the
ALTER AUDITDUMP command description. Their default values are as follows:
BLOCKSIZE, the tape data block length: 28 (x 1024 bytes)
COPIES, the number of copies to be made in series or in parallel of each
dump: 1 parallel
SYSTEM, the node (system) on which tape copies are made: the local node
VERIFYTAPE, the tape-verification selection: OFF
MEDIUM, the medium on which the dump is recorded: TAPE
FILESIZE integer
specifies the size of the audit-trail files, in megabytes (MB). The minimum value
for FILESIZE is 1 and the maximum depends on the format of the audit-trail files,
as follows:
•
For format 1 files: 2047 or the maximum disk size (if less than 2047 MB).
•
For format 2 files: 1048575 or the maximum disk size (if less than 1048575
MB). (Note that 1048575 equals 1 terabyte (TB) minus 1 megabyte (MB).)
The default is as follows:
•
For format 1 files, 100 (resulting in files of 100 MB each).
•
For format 2 files, 1024 (resulting in files of 1024 MB each).
At any point after the FILESIZE attribute value is set, you can change it by issuing
the ALTER AUDITTRAIL command.
Note. An auxiliary audit trail cannot be configured with AUDITDUMP ON unless the
master audit trail is also configured with AUDITDUMP ON. A master audit trail cannot be
configured with AUDITDUMP OFF unless the auxiliary audit trails are also configured with
AUDITDUMP OFF. However, a master audit trail can be configured with AUDITDUMP ON
regardless of whether AUDITDUMP is ON or OFF for the auxiliary audit trails. The
possible combinations are:
MAT AUX Allowed/Disallowed
------ ------ --------------------------
ON ON Allowed
OFF OFF Allowed
ON OFF Allowed
OFF ON Disallowed
Caution. FILESIZE values smaller than 300 MB are not recommended. A FILESIZE value of
1 MB should really never be used.
