Supported UNIX Utilities
Smart Scripting supports the invocation of the following UNIX utilities in the scripts
you run:
datasize 131,072 KB Maximum size of the data segment for a process; this value defines
how far a program may extend its break with the sbrk(2) system call.
stacksize 2,048 KB Maximum size of the stack segment for a process; this value defines
how far a program's stack segment may be extended. Stack extension
is performed automatically by the system.
coredumpsize unlimited Largest size of a core file that may be created
memory use 233,244 KB Maximum size to which a process’s resident set size may grow. This
value imposes a limit on the amount of physical memory to be given to
a process; if memory is tight, the system will prefer to take memory
from processes that are exceeding their declared resident set size.
memorylocked 77,741 Maximum size (in bytes) which a process may lock into memory using
the mlock(2) function.
maxproc 160 Maximum number of simultaneous processes allowed for the user ID.
