SET AUDITTRAIL
FILESIZE integer
specifies the size of the audit-trail files, in megabytes (MB). The minimum value is 
1 and the maximum value is either 2047 or the maximum disk size (if less than 
2047 megabytes.) The default value is 100, resulting in files of 100 MB (100 x 
1,048,576 bytes) each. 
ACTIVEVOL[S]
specifies the disk volumes that hold the audit-trail files. At least one volume must 
be specified for this purpose, either in a SET AUDITTRAIL command or a 
subsequent ADD AUDITTRAIL command. Up to 16 volumes can be specified as 
active-audit volumes. 
A single volume cannot be configured as an active volume for more than one audit 
trail. A volume configured as an active-audit volume cannot be configured as a 
data volume. To add more volumes to the configuration later, you can use the 
ALTER AUDITTRAIL command.
Volumes of the same size should be used for a specific audit trail. TMF allocates 
the same number of files on each volume, and all volumes must be able to hold all 
of those files. If a mixture of large and small disks is used for an audit trail, some 
portion of the large disks will be underused because the active-audit trail will not 
use them and they cannot be used for audited files; such large volumes, however, 
could be configured as overflow space or audit restore space.
FILESPERVOLUME integer
specifies the number of files in the audit trail that reside on each active-audit 
volume configured. The audit trail’s capacity is determined by the number of audit- 
trail files per volume, the number of active-audit volumes configured for the trail, 
and the size of those files. 
TMF preallocates the configured number of files when a subsequent ADD 
AUDITTRAIL command is executed. If TMF cannot allocate all the files, the ADD 
AUDITTRAIL command fails.
The minimum value for FILESPERVOLUME is 1 and the maximum value is 100. 
The default is 5. 
The FILESPERVOLUME value can be altered later, even while TMF is running, by 
using the ALTER AUDITTRAIL command.
OVERFLOWVOL[S]
specifies the volumes to be used as overflow space for the audit trail, if required  
(this attribute is not required by TMF, but if you omit it, TMF issues a warning event 
message at TMF startup, indicating that an overflow-audit volume should be 
configured). You can specify from 1 to 16 overflow volumes. These can be the 
same volumes as the active-audit volumes; they can also be data volumes or any 
volumes not configured for any other TMF purposes. To change the overflow-audit 
volumes later, you can use the ALTER AUDITTRAIL command.
