Hi:

You can control the maximum file size on a process basis with 'ulimit'. See the man pages for 'ulimit(2)' and for 'sh-posix(1)' for more information.

Hello,

file_pad - - 10
maxfiles 1024 - 1024
maxfiles_lim 1024 Y 1024
nfile 4096 - 4096
sendfile_max 0 - 0

The size of the files or the number of files?

The number of files is controlled through the kernel paramters maxfiles (soft limit) and maxfiles_lim (hard limit).

I guess you are looking for this parameter:pa_maxssiz_32bit.

To verify please find the details of the parameter as below:

Tunable pa_maxssiz_32bit
Description Maximum size of the stack segment of a 32-bit PA-RISC pr
Dynamic no
Subsystem vm
Default Value 83648512
Current Value 83648512
Planned Value 83648512
Last Boot Value 83648512
Constraints pa_maxssiz_32bit >= 83648512
Constraints pa_maxssiz_32bit <= 468713472
Auto Tuning Not Supported
Current Usage Not Available

maxssiz (32 or 64 bit) has nothing to do with maximum file handles available to a process. pa_maxssiz_32bit has even less to do with it -- since that's stack size of a PA binary running on IPF using the Aries emulator. [Just trying to clarify before someone gets the wrong idea].

Pete has it right, look at maxfiles / maxfiles_lim for the system wide limits, then ulimit if you want to fine tune the "soft" limits.
