Determines
whether the host’s SSCP does all the gateway control functions
during LU-LU session setup. GWCTL determines the SSCP’s role
for only the gateway NCP being defined, and applies only if the SSCP
is on the session setup path.
- GWCTL=ONLY
- Specifies that only one SSCP controls the gateway NCP.
If the session setup path crosses three networks within a single gateway NCP, and if one or more gateway SSCPs are in session with the gateway NCP, the gateway SSCP in the center network must be designated to perform all of the gateway functions. Code GWCTL=ONLY on the PCCU statement for the gateway SSCP in the center network.
- GWCTL=SHR
- Indicates control of the gateway NCP is shared. If one gateway SSCP cannot perform the gateway control function, the other SSCP performs the function.
For an inactive NCP, the VARY ACT command processes all operands coded on the PCCU definition statement. The VARY ACQ command, however, processes only the GWCTL operand, regardless of what is coded on the PCCU definition statement.
