Use this command to activate one or more Common Link Access to Workstation
(CLAW) workstations.
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).
Format
- WS-wsname
- activates the specified CLAW workstation, where wsname is the 1-
to 8-character alphanumeric name of the CLAW workstation.
- SDA-sda
- activates the specified CLAW workstation, 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'). The write channel unit is always the following
odd hexadecimal number (for example, X'21').
- ALL
- activates all of the CLAW workstations that are defined for this TPF host
processor.
Additional Information
- Online help information is available for this command. To display
the help information, enter one of the following:
ZCLAW HELP
ZCLAW ?
- Although you can activate a CLAW workstation in 1052 state, socket
applications are not activated until the TPF system is cycled to CRAS state or
higher.
- If you perform an initial program load (IPL), the TPF system will
automatically attempt to reactivate all of the active CLAW
workstations.
Examples
The following information is displayed in the examples:
- WS
- is the CLAW workstation name.
- HOSTA
- is the CLAW host application name.
- WSA
- is the CLAW workstation application name.
- SDA
- is the symbolic device address of the read channel unit for the CLAW
workstation.
The OS2TCP workstation is activated in the following example.
