Keeping Current System Information

You can easily keep track of your TMF system and other system components by

maintaining a command file that contains a copy of your present configuration, and by

printing copies of the output from TMF status and information commands and other

system reports you routinely run. Keeping this information organized by subject and

date in a notebook will provide easy access when you need information about a

specific part of your system:

•

To capture a fully runnable copy of your current configuration in a command file,

issue the INFO TMF, CNFGFORM command. This command file will contain all

TMFCOM commands needed to reconfigure and start TMF, producing a running

system that exactly matches your present configuration. (The INFO TMF,

CNFGFORM command, however, does not capture dump information from the

TMF catalog.)

•

When you want to reconfigure your TMF system and need audit-trail capacity

figures or typical transaction rates, you can refer to the output from previous

STATUS AUDITTRAIL, DETAIL commands.

•

If you have to rebuild your TMF catalog and need complete information about all

TMF dumps, you can refer to the output from previous INFO DUMPS, OBEYFORM

commands. (The output from the INFO DUMPS, OBEYFORM command augments

the configuration information captured by the INFO TMF, CNFGFORM command,

which together provide a total view of your overall TMF system.)

•

If there is a recurring problem on your system, you can keep the output from

DISPLAY OPERATIONS commands to compile a historical record of system

events.

•

To keep a historical account of disk space and file errors, you can generate various

DSAP reports (see the Guardian Disk and Tape Utilities Reference Manual for

information).

It is very important to protect your system by performing routine backups of the TMF

catalog and configuration files, and the EMS log. Whenever you change the TMF

configuration, note the changes in your system notebook and create a new backup of

the configuration files by using the INFO TMF, CNFGFORM command.
