Configuration Parameters for SNAX/APC
The RMTATTACHTIMER value may be changed by specifying the
REMOTEATTACHTIMER parameter on the SCF or SPI ALTER TPN command.
SECURITYMANAGER { NONE | SAFEGUARD }
specifies whether or not the Safeguard subsystem will be employed as the security
manager. If SECURITYMANAGER is not specified, the default value is NONE.
TRACEFILE trace-file-name
designates the trace file and activates the trace collection. Here is an example of
usage:
PARAM TRACEFILE $QA3.APCCONF.TAPFILE1
RUN APCOBJ/NAME $AL01, NOWAIT, CPU 1/2
or
RUN APCOBJ/NAME $AL01, NOWAIT, CPU 1/2, TRACEFILE &
$QA3.CONF.TAPFILE
The SCF TRACE command may overwrite any setting established with this
parameter.
If TRACEFILE is not given as a PARAM, a default tracing option is turned on. A
trace file named <apc-process-name>TRC is created in the default subvolume and
minimal tracing is performed.
TRACEOPTION number
specifies the type of records that SNAX/APC is to capture when the trace facility is
on. Each trace option is represented by one of 16 bits in an integer. Allowable
values are from -32768 to 32767; the default value is -1 (all bits set), which specifies
that all types of data are to be traced. See the following list for the types of data that
can be captured and their corresponding values. To capture several types of data at
once, add their values together and specify the sum in this parameter.
-32768 Trace records obtained and returned to local or extended buffer pool.
16384 Trace enqueuing and dequeuing of internal buffers.
8192 Trace BIUs (basic information unit) sent to and received from SNAX
LUs.
4096 Trace data sent between TPs and SNAX/APC.
2048 Trace data handled by internal procedures of SNAX/APC.
1024 Trace the FSMs (finite state machines) for the LUNS (LU Network
Services) layer.
512 Trace the FSMs for the RM (resource manager) layer.
256 Trace the FSMs for the PS (presentation services) layer.
