Use this command to do the following:
- Delete a Common Link Access to Workstation (CLAW) workstation
definition.
- Delete a definition for a specific CLAW host application and CLAW
workstation application pair on a particular CLAW workstation.
Requirements and Restrictions
- You can enter this command only in 1052 state or higher.
- You can enter this command only from the basic subsystem (BSS).
- You cannot delete a definition for an active CLAW workstation. If
the CLAW workstation is active, enter the ZCLAW INACTIVATE command to
deactivate it before you enter this command.
- Do not use this command if your loosely coupled complex has processors
that are using a TPF image that includes 32-way loosely coupled processor
support and other processors that are using an image that does not include
32-way loosely coupled processor support. Any CLAW workstations that
are deleted on a processor with 32-way loosely coupled processor support will
have to be deleted again if that processor falls back to a previous level of
support.
Format
- WS-wsname
- deletes the definition for the specified CLAW workstation, where
wsname is the 1- to 8-character alphanumeric name of the CLAW
workstation.
- WSAppl-wapplname
- deletes the definition for the specified CLAW workstation application,
where wapplname is the 1- to 8-character alphanumeric name of the
CLAW workstation application.
- HOSTAppl-happlname
- deletes the definition for the specified CLAW host application, where
happlname is the 1- to 8-character alphanumeric name of the CLAW host
application.
- SDA-sda
- deletes the definition for the CLAW workstation that has the specified
symbolic device address, where sda is the 1- to 4-digit hexadecimal
symbolic device address of the read channel unit on the CLAW
workstation.
- Note:
- Symbolic device addresses are always assigned in read/write pairs. In
the TPF system, the symbolic device address assigned to the read channel unit
is always an even hexadecimal number (for example, X'20')
and the write channel unit is always the following odd hexadecimal
number (for example, X'21').
