APPC Subsystem on MPE/XL Node Manager's Guide (30294-90007)

Chapter 3 63
Control Operator Intrinsics
APPCStart
APPCStart
Activates the APPC subsystem and all APPC sessions configured for
automatic activation.
Syntax
I32 I16V CA I16V
APPCStart ( ReturnCode [, TraceOn ] [, TFileName ] [, TFileSize ]
I16V I16V
[, PerformanceOn ] [, Erropt ])
Parameters
ReturnCode
Required. 32-bit signed integer; output. Indicates the
result of the intrinsic execution. The
ReturnCode
consists of two 16-bit fields: an information field,
containing the number of an APPC warning or error
message, and a subsystem field, containing the number
of the subsystem that generated the message. If both
fields contain zeros, the intrinsic executed successfully,
and there are no messages. For more information, see
“Return Codes” at the beginning of this chapter.
Appendix A , “Messages,” contains a list of all return
codes returned by the APPC subsystem, their causes,
and the actions you should take to resolve any
problems.
TraceOn
Optional. 16-bit signed integer; input. Specifies
whether or not internal state tracing will be performed.
Internal tracing records significant state changes,
events and data to a disk file. Possible values are as
follows:
1 Internal state tracing is enabled.
Tracing will remain on until the
APPCCONTROL TRACEOFF command is
issued or until the APPC subsystem is
stopped.
0 Internal state tracing is disabled.
Tracing will remain off until the
APPCCONTROL TRACEON command is
issued.
