In an AIX box, 5300-05, I want to change pipe size, I tried from /etc/security/limits and rebooted, still older value.

bash-2.04# ulimit -a
core file size (blocks) unlimited
data seg size (kbytes) unlimited
file size (blocks) unlimited
max memory size (kbytes) unlimited
open files unlimited
pipe size (512 bytes) 64
stack size (kbytes) 2097151
cpu time (seconds) unlimited
max user processes 262144
virtual memory (kbytes) unlimited
Can anyone suggest how to change this value?

Thanks n Regards

The parameter is not listed in my output.
Could it be a bash-limit?

Thats weird how it would get printed in bash. Its a system wide limit .. so why exactly do you want to change it ?

$ grep -i pipe /usr/include/sys/limits.h

#define _POSIX_PIPE_BUF 512

Yes, it shows only in "bash". Its an application's requirement.
Can we change it in include library?
