maxssiz and maxssiz_64bit
maxssiz and maxssiz_64bit set the maximum
dynamic storage segment (DSS) size in bytes.
maxssiz for 32-bit processors:
0x4000 (16 Kbytes)
0x17F00000 (approx 200 Mbytes)
0x800000 (8 Mbytes)
maxssiz_64bit for 64-bit processors:
0x4000 (16 Kbytes)
1073741824
0x800000 (8 Mbytes)
Specify integer value. For more information, see Specifying Parameter Values.
Enter the value in bytes.
maxssiz and maxssiz_64bit define, for 32-bit
and 64-bit processors respectively, the maximum size of the dynamic
storage segment (DSS), also called the user-stack segment, or an
executing process's run-time stack. This segment contains stack and
register storage space, and such.
The default DSS size meets the needs of most processes. Increase the
value of maxssiz or maxssiz_64bit only if you
have one or more processes that need large amounts of dynamic
storage.
The stack grows dynamically. As it grows, the system checks the size of
the process' stack segment. If the stack size requirement exceeds
maxssiz or maxssiz_64bit, the system
terminates the process.
