Hello Nishith,

The relevant file on NCR are mtune and stune files. This will be available in the /etc/conf/cf.d directory on the server.

Check the man pages of stune and mtune for more details.

Regards
Amith

Here is a link to configurable kernel parameters in HP-UX. Its hard to search on given your definitions, which I've pasted below. Perhaps another forum member will recognize their counter part.

MAXAIOS
Description
The MAXAIOS parameter indicates the total number of system daemons that
can be created to perform asynchronous I/O.
â ¢ï  ï  Range - 1 - 64
â ¢ï  ï  Default - 5


ARG_MAX
Description
The ARG_MAX parameter specifies the maximum number of characters
(including NULL characters) allowed in the argument and environment strings
passed to an exec system call.
â ¢ï  ï  Range - 1024 - 51200
â ¢ï  ï  Default - 5120

NUMTRW
Description
The NUMTRW parameter specifies the maximum number of transport
interface read/write STREAMS modules available if the STREAMS transport
interface read/write module (tirdwr) is included in the system.
â ¢ï  ï  Range - 1 - 8192
â ¢ï  ï  Default - 16

UFSNINODE
Description
The UFSNINODE parameter specifies the number of ufs inode table entries,
and thereby limits the number of files in ufs file systems that can be open at
one time.
If the root file system is ufs and many small files are used, you may need to
increase the value of UFSNINODE. If predominantly very large files and/or
raw partitions are used, you need fewer inodes and the default should be more
than adequate.
â ¢ï  ï  Range - 100 - 5000
â ¢ï  ï  Default - 500

NCDINODE
Description
The NCDINODE parameter specifies the number of cdfs inode table entries,
and thereby limits the number of files in cdfs file systems that can be open at
one time.
â ¢ï  ï  Range - 64 - 2048
â ¢ï  ï  Default - 256

NAUTOPUSH
Description
The NAUTOPUSH parameter specifies the number of devices that can be
configured to be auto-pushed onto a stream.
â ¢ï  ï  Range - 32 - 32
â ¢ï  ï  Default - 32


NAIOSYS
Description
The NAIOSYS parameter specifies the maximum number of outstanding
asynchronous I/O system calls that can be active at any given time.
â ¢ï  ï  Range - 0 - 4096
â ¢ï  ï  Default - 300
