Configuration Parameters for SNAX/APC
COLLECTOR-2 [ collector-file-name-2 ]
specifies the identity of alternate EMS collector number 2. If this parameter is
omitted or used with no argument, output to this collector is suppressed.
The COLLECTOR-2 value may be changed by specifying the COLLECTOR-2
parameter on the SCF or SPI ALTER PROCESS command.
COLLECTOR-3 [ collector-file-name-3 ]
specifies the identity of alternate EMS collector number 3. If this parameter is
omitted or used with no argument, output to this collector is suppressed.
The COLLECTOR-3 value may be changed by specifying the COLLECTOR-3
parameter on the SCF or SPI ALTER PROCESS command.
CONFIG configuration-file-name
designates a permanent configuration database for the SNAX/APC process. If the
database file already exists, the SNAX/APC process will read the entire
configuration and perform a warm start. Otherwise, the SNAX/APC process will
come up without any configuration and create a database file ready for online
configuration.
If the CONFIG parameter is not specified, the SNAX/APC process will be started
without any configuration, and all of the objects added subsequently will not be
retained after SNAX/APC is stopped, although a temporary file is created.
Here is an example of how to specify the CONFIG parameter:
PARAM CONFIG $QA3.APCCONF.AL01
RUN APCOBJ/NAME $AL01, NOWAIT, CPU 1/2
or
RUN APCOBJ/NAME $AL01, NOWAIT, CPU 1/2, CONFIG &
$QA3.APCCONF.AL01
The CONFIG value may be changed by specifying the CONFIG parameter on the
SCF or SPI ALTER PROCESS command.
DATAPAGES number [ E | EXTENSIBLE ]
specifies the maximum number of 2048-byte pages that the SNAX/APC process can
have in its extended segment for external buffers. Allowable values are from 0
through 65280 (an even number is expected; odd values are incremented by 1). If
you specify the option E or EXTENSIBLE following the numeric value, the segment
will be extensible. This extensible mode of operation allows the subsystem to
allocate disk space on an as-needed basis. When operating in extensible mode, an
initial allocation depends upon many factors, including subsystem parameters
specified at startup time. If this initial allocation succeeds, storage will be extended
as needed until one or more of the following conditions exists: the upper limit
specified has been allocated, the virtual memory limit is reached or the underlying
disk file space is unavailable. The default value is 2040 EXTENSIBLE. A value of
0 also gives you the default value of 2040 EXTENSIBLE.
