Hello All...

I had dooubt, How to change the ulimite value of an user;

Following is an current ulimit of a particular user:

zcmadm> ulimit -a
time(seconds)        unlimited
file(blocks)         unlimited
data(kbytes)         1048576
stack(kbytes)        8192
memory(kbytes)       unlimited
coredump(blocks)     4194303
nofiles(descriptors) 2048

I need to change it to;

Proposed Value
============
time(seconds) unlimited
file(blocks) unlimited
data(kbytes) unlimited
stack(kbytes) unlimited
coredump(blocks) unlimited
nofiles(descriptors) 8192

data(kbytes) unlimited
stack(kbytes) unlimited
coredump(blocks) unlimited
nofiles(descriptors) 8192

You can change coredump with the ulimit command.

The others need to use kctune(1m) to change the values of kernel parms:

maxdsiz(5) & maxdsiz_64bit(5), maxssiz(5) & maxssiz_64bit(5), maxfiles(5), maxfiles_lim(5)

Note: You can't make the sizes unlimited, you can only increase the kernel parms.

Note: Making maxssiz too large will decrease maxdsiz.

Note: The *_64bit forms must be bigger than the 32 bit limit.
