Use this command to do the following:
- Define a Common Link Access to Workstation (CLAW) workstation for this TPF
host processor.
- Define the CLAW host name for this TPF host processor.
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).
- 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 defined on a processor with 32-way loosely coupled processor support will
be lost if that processor falls back to a previous level of support.
Format
- HOSTAppl-happlname
- is the 1- to 8-character alphanumeric name of the CLAW host
application.
- Note:
- If you are using a IBM 3172 Model 3 Interconnect Controller for your TCP/IP
offload device, you must specify TCPIP for this parameter.
- WSAppl-wapplname
- is the 1- to 8-character alphanumeric name of the CLAW workstation
application.
- Note:
- If you are using a IBM 3172 Model 3 Interconnect Controller for your TCP/IP
offload device, you must specify API for this parameter.
- WS-wsname
- is the 1- to 8-character alphanumeric name of the CLAW workstation.
- Note:
- If you are using a IBM 3172 Model 3 Interconnect Controller for your TCP/IP
offload device, you must specify OS2TCP or OS3172xx for this
parameter, where xx is 2 unique alphanumeric characters.
- SDA-sda
- is the 1- to 4-digit hexadecimal symbolic device address of the read
channel unit for 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').
- HOSTName-hostname
- is the 1- to 8-character alphanumeric CLAW host name for this TPF host
processor.
- Note:
- If you are using a IBM 3172 Model 3 Interconnect Controller for your TCP/IP
offload device, you must specify TCPIP for this parameter.
