os.ulimit
os.umask
os.userLimits
os.versionNumber
Platform Description
UNIX Checks whether an unlimited number
of processes can be run based on the
following qualification attributes:
v type attribute, to determine which
additional limit to check, for
example, the filedescriptorlimit
checks the limit for the number of
file descriptors that processes can
open
Alternatively it checks whether the
following limits have been set for the
specified domains in the
/etc/security/limits.conf file:
root - stack
ctginst1 - stack
root - nofile
tioadmin - nofile
UNIX Checks the permissions for the file
mode creation mask
UNIX Checks whether the maximum stack
size is unlimited; returns Available if
it is unlimited
Windows Checks the current version of the
operating system that is installed on
the machine
Valid values
The value can be any of the
following types:
v String with the following
qualifier format:
[type:limit_name]
limit_value,
limited|unlimited
For example, to check
whether the file descriptor
limit is greater than 8192,
with unlimited number of
processes:
os.ulimit=[type:
filedescriptorlimit]
unlimited
8192+,
unlimited
unlimited
8192
32767
Valid types of limits to
check, where limit_name
represents the type of limit
are as follows:
– ALL, checks all limits
– corefilesizelimit
– datasegmentlimit
– filedescriptorlimit
– filesizelimit
– hardlimit
– processlimit
– maxmemorysizelimit
– maxprocesseslimit
– stacksizelimit
– threadlimit
v Available|Unavailable to
specify whether the relevant
domains have limit sets in
the /etc/security/
limits.conf file.
Number to represent the
octal_digits octal digits for
the access permissions. For
example, to check that new
files are only writeable for the
owner, set the octal digit to be
0022
Available|Unavailable
Numeric format, for example,
5.0+
Note: The values can use the
special characters as outlined
