Defining Attributes for Guardian and OSS Servers
•
The files that your server program recognizes by the names ORDERS and PARTS
are the files $DATA.REG1.ORDFILE and $DATA.REG2.PARTFILE, respectively.
(ASSIGN attribute.)
•
The PATHMON process starts the first server process in the server class in
processor 2, the second server process in processor 3, and the third in processor
0.
If processor 2 is down, the PATHMON process instead starts the first server
process in processor 4 as the backup processor for the first process. Similarly,
CPUs 5 and 6 are the backup CPUs for the second and third server processes,
respectively. If the PATHMON process starts more than three server processes, it
reuses the CPUs in the order specified: for example, a fourth server process would
start in processor 2 if that processor were available. (CPUS attribute.)
•
The total number of all server processes in the server class that the PATHMON
process can run simultaneously is five. (MAXSERVERS attribute.)
•
The total number of static server processes allowed is three. (NUMSTATIC
attribute.)
•
When the PATHMON process starts a server process, it transmits this PARAM
message:
SWITCH-1 “ON”
(PARAM attribute.)
•
The object code for the server class is stored in the file
\SYS.$DATA.SRVRS.ORDSRV. (PROGRAM attribute.)
Attributes That Apply Only to OSS Servers
These attributes are valid only for OSS servers:
•
ARGLIST specifies a set of process startup parameters.
•
CWD specifies the current working directory to be used to resolve relative OSS
filenames specified for server attributes such as PROGRAM, STDIN, STDERR,
and STDOUT. The current working directory pathname is combined with a relative
pathname to create an absolute OSS filename. (The OSS concept of an absolute
filename is similar to the Guardian concept of a fully qualified file name that
includes system, volume, and subvolume.)
An OSS absolute filename can be up to 1024 characters long.
If you have issued the CMDCWD command to establish a working directory, you
do not need to set the CWD attribute. However, if you have issued the CMDCWD
command, you can set the CWD attribute for a given server class to change the
working directory just for that server class.
•
ENV specifies environmental variables for the server processes in this server
class.
