TMFCOM Commands

HP NonStop TMF Reference Manual—522418-002

3-111

DELETE TMF

The DELETE TMF command purges the entire TMF configuration, including volume

and file recovery information for the database. Only tape media names are retained in

the TMF catalog.

This command, entered only when TMF is stopped, produces an empty configuration

with no audit trails and with default values for other configuration information. DELETE

TMF is typically used to make major configuration changes.

Security Restrictions

You can enter the DELETE TMF command only if you are logged on under the super

ID; the super ID is the person with the user ID 255,255−in effect, the group manager of

the super user group.

TMF State Requirement

You cannot use the DELETE TMF command while TMF is running; if you have started

TMF, you must stop it with the STOP TMF command before entering DELETE TMF.

Usage Guidelines

The DELETE TMF command is not allowed in either command files or the parameter

line of the TMFCOM command that starts a noninteractive session. This command

must only be entered interactively−that is, in response to the TMFCOM interactive

prompt (TMF line-number>).

Caution. Contact the Global Customer Support Center (GCSC) or your service provider

before issuing this command.

Use extreme caution when entering the DELETE TMF command, because this command

removes TMF’s ability to recover database files. This command can leave the database in an

inconsistent or damaged state, potentially affecting both local and remote nodes on which

shared distributed transactions exist.

TMF is shipped from the factory with the $AUDIT disk volume configured as the active-audit

volume and the $DSMSCM disk volume configured as a TMF data volume. If you use the

DELETE TMF command, you must subsequently respecify an active-audit volume ($AUDIT or

some other volume, through the ADD AUDITTRAIL command), and a TMF data volume

($DSMSCM or another volume, through the ADD DATAVOLS command); if you do not do so,

you cannot restart TMF.
