ADD AUDITTRAIL
OVERFLOWTHRESHOLD integer
specifies the percentage of audit trail capacity that can be consumed before TMF
begins overflow copying. This is an optional parameter. The minimum value is 50
and the maximum is 100. The default is 80(%).
RESTOREVOL[S]
specifies the volumes used when restoring audit dumps during execution of a
RECOVER FILES command. If audit dumping is configured for the audit trail, you
must specify at least one volume for this purpose.
You can specify from 1 to 16 restore-audit volumes. These can be the same
volumes as the active-audit volumes; they can also be data volumes or any
volumes not configured for other TMF purposes. To change the restore-audit
volumes later, you can use the ALTER AUDITTRAIL command.
BEGINTRANSDISABLE integer
specifies the percentage of audit trail capacity that can be consumed before TMF
disables new transactions. When the consumed capacity falls below this
threshold, new transactions are no longer disabled by audit-trail usage. (However,
new transactions can be disabled for other reasons, as explained in the ALTER
BEGINTRANS command description.) The minimum value is 50 and the
maximum is 100. The default is 90(%).
Security Restrictions
You can issue the ADD AUDITTRAIL command only if you are a member of the super
user group.
TMF State Requirement
You can only issue ADD AUDITTRAIL commands under either of two conditions:
1. Before you start TMF for the first time with the START TMF command.
2. After you stop TMF with the STOP TMF command and purge the existing TMF
configuration with the DELETE TMF command but before you issue the next
START TMF command.
Under either of these conditions, you can issue multiple ADD AUDITTRAIL commands.
Usage Guidelines
There must be exactly one master audit trail in a TMF system. In addition, there can
be up to 15 optional auxiliary audit trails. Auxiliary audit trails receive the audit
information generated by a specified set of data volumes; they do not contain TMF
control information. Auxiliary audit trails can be added to a TMF configuration to
increase overall auditing capacity and bandwidth, or to logically separate operations
