Configuration Parameters for SNAX/APC
specifying an asterisk, output is sent to the default outfile, which is normally the
home terminal. You are advised to use the EMS collectors, rather than the log file,
to collect and examine event messages.
Specifying the log file as a disk file presumes that the file already exists. The
SNAX/APC process will not run if the specified disk file does not exist. One such
disk file could be created with the statement:
FUP CREATE file-name, TYPE E, REC 132, EXT (pri, sec)
where file-name identifies the file to be created, and pri, sec define the size of
the primary and secondary extents. LOGFILE * designates the standard OUT file as
the logging device. Omitting the LOGFILE parameter, or specifying the LOGFILE
parameter without arguments, will inhibit logging.
The LOGFILE value may be changed by specifying the LOGFILE parameter on the
SCF or SPI ALTER PROCESS command.
MAXAPPLIOSIZE bytes
specifies the maximum number of bytes the SNAX/APC application can send to or
receive from the SNAX/APC process (maximum size of an IPC message).
Allowable values are from 256 to 32,000. The default value is 5000. (COBOL
programmers should note that large IPC messages—of approximately 32,000
bytes—can consume the space for COBOL I/O buffers very quickly.)
MAXINRUSIZE bytes
specifies the maximum number of bytes in the incoming SNA data field
(Request/Response Unit) from the Tandem access method (if the value is not
specified in a BIND). Allowable values are in the range 16 through 16,000. The
default value is 256. This specifies the default value for the SNAX/APC process.
Individual PTNR-MODE objects may specify different values. If a
MAXINRUSIZE value is not specified for an individual PTNR-MODE object, it
gets this value.
If SNAX/APC is the primary LU, it sends this value in the BIND request.
If SNAX/APC is the secondary LU, its BIND response returns the lesser of
MAXINRUSIZE and the size specified in appropriate field of the BIND RU.
If the BIND RU size is less than 16, SNAX/APC returns 16.
MAXOPENS number
specifies the maximum number of application program OPENs that can be active
concurrently. Any integer in the range 1 through 1500 can be specified.
The default value is 512.
MAXOUTRUSIZE bytes
specifies the maximum number of bytes in the outgoing SNA data field
(Request/Response Unit) to the Tandem access method. Allowable values are in the
range 16 through 16,000; 256 is the default. This specifies the default value for the
SNAX/APC process. Individual PTNR-MODE objects may specify different
