Sending a Command Message
header-type
is the value of ZSPI-VAL-CMDHDR, which specifies the type of SPI buffer. This
value is always zero.
command
is the value of ZSPI-TKN-COMMAND.
object-type
is the value of ZSPI-TKN-OBJECT-TYPE.
max-resp
is the value of ZSPI-TKN-MAXRESP.
server-version
is the value of ZSPI-TKN-SERVER-VERSION.
checksum
is the value of ZSPI-TKN-CHECKSUM.
max-field-version
is the value of ZSPI-TKN-MAX-FIELD-VERSION.
4. Call the SSPUT or SSPUTTKN procedure to add a token to the buffer. The two
procedures are identical except that SSPUT passes a token ID by reference and
SSPUTTKN passes it by value. If the management application interacts with the
SCP, you must add a token named ZSPI-TKN-MANAGER, which identifies the
target subsystem. For the WAN manager, the token's value is always $ZZWAN.
5. Call the WRITEREAD procedure to send the command buffer to the WAN
manager.
Note. The management application includes a token ZSPI-TKN-ALLOW-TYPE in the
command buffer, based on the command at the SCF prompt, which can be ALLOW ALL,
ALLOW NO ERRORS, and ALLOW NO WARNINGS. The management application also
includes a token ZCOM-TKN-CMD-TIMEOUT in a command buffer, to specify the number of
microseconds an SCP process waits for a response from the subsystem to which SCP
forwarded the command. If this time is exceeded and the command has not been completed,
the command is canceled.
