Configuring and Starting
Application Processes by
Using Process Definitions
You can configure and start static and dynamic BK, EM, IS, MS, and NC processes by
using process definitions in a CONFIG file. Use process definitions in a CONFIG file if
you want to start BK, EM, IS, MS, or NC processes with other than the default values
for execution attributes or logical names.
The CONFIG file must include enough application process definitions to support at
least one occurrence of the BK, EM, IS, and MS function: otherwise, NonStop
NET/MASTER MS cannot start.
In basic mode, this requirement is fulfilled by the occurrence of the NC process, which
is created as the default process class. The NC process combines the functions
performed by the BK, EM, IS, and MS processes. In extended basic mode, this
requirement is also fulfilled by the occurrence of the NC process, which supplements
the other processes that are present, for example, IS and MS processes. In advanced
mode, this requirement is fulfilled by the presence of at least one BK, EM, IS, and MS
process.
The same program file can be used to start all application process classes. You would
usually specify the same program file name, with the PROCESSOBJECT operand, in
all application process definitions. There is no need to use a separate copy of the
program file for each process definition or process class; this uses up disk space
unnecessarily.
You can include or omit the PROCESSCLASS operand in an application process
definition. If you include the PROCESSCLASS operand, the NCP uses the value of the
operand, which must be BK, EM, IS, MS, or NC, to determine the class of the
application process. If you omit the PROCESSCLASS operand, the NCP uses the file
name specified by the PROCESSOBJECT operand to determine the class of the
application process, as follows:
If the file name has four or more characters, the third and fourth characters (if BK,
EM, IS, MS, or NC) determine the process class created from the file name: a BK,
EM, IS, MS, or NC process, respectively.
If the file name has less than four characters or the third and fourth characters are
not one of BK, EM, IS, MS, or NC, the process class is NC.
The following table summarizes the relationship between the file name specified by
the PROCESSOBJECT operand and the process class created from the file name:
PROCESSOBJECT File Name Process Class Created
xxBK∗ BK
xxEM∗ EM
xxIS∗ IS
xxMS∗ MS
xxNC∗ NC
∗ (∗ are any other characters) NC
