2 Doing an Initial Configuration
This section provides advice for doing your initial TMF configuration. It is assumed that
you are configuring only the master audit trail. Advice for later performance tuning of
audit trails and for tasks performed in special cases, such as configuring auxiliary audit
trails and changing the begin-transaction-disable threshold, is given in Section 3,
Reconfiguring Audit Trails.
This section contains the following topics:
The Major Steps
Unless a previous TMF configuration exists, a system cold load creates an empty TMF
configuration that includes no audit trails, no data volumes, an empty TMF catalog, and
default parameters for all TMF processes.
Therefore, the general steps you must perform to configure a typical TMF environment
after a cold load are as follows:
1. Add the master audit trail (MAT).
2. Start TMF.
3. Add the data volumes.
4. Alter the audit dump configuration to generate two parallel copies of each dump.
5. Add scratch tapes to the TMF catalog.
6. If you need the file recovery capability, make online dumps of all database tables
and files.
You use TMFCOM commands to perform these configuration tasks. For detailed
information about TMFCOM commands, refer to the TMF Reference Manual.
If there was a previous TMF configuration, a system cold load merely reestablishes it,
and there is no need to perform the listed steps.
