Preparing to Use SMF
The installation of SMF, which includes support for location independent naming, can
have some remote access, operational, and performance impact on certain types of
applications.

TMF Usage
SMF requires the use of TMF to protect the SMF catalog files. Therefore, if SMF is to
be installed on a system where TMF is not running, that system must first be upgraded
to use TMF. HP recommends that at least file recovery, volume recovery, and
transaction protection be used for SMF catalog files.
Most applications and operational procedures related to TMF continue to work
unchanged after SMF is installed and in use.
TMF Audit Records
TMF audit records were enhanced in the D42 RVU to contain both logical and physical
file names to support SMF logically named files. Audit records generated by the disk
process (DP2) include both names in audit records for both logically named and direct
files. Note that the logical file name field adds 36 bytes to each audit record containing
a data file name.
The logical file name is used for file recovery purposes and for RDF and SQL physical
database reorganization operations, so that audit trail readers can determine the
logical file name for particular audit records.
If you use public audit reading routines, you do not need to change these routines after
conversion to SMF. The file name returned is the logical name; therefore, applications
Caution. To avoid recovery issues, do not place TMF audit trails on SMF logical volumes.
They can, however, be directly placed on a volume that is configured in an SMF pool.
