1. I really REALLY hope you do not have number of data buffers set to
3072; that's ludicrously high. A reasonable number for LTO3 drives would
be 32 with size data buffers of 262144. Don't forget that the amount of
shared memory required by NBU is size data buffers * num data buffers *
mpx * number of drives. With your settings your looking at 400Mb of
shared memory before you take into account mpx and 

2. With solaris 10 you should not be changing the /etc/system file - a
lot of settings that you'd put in there for Sol9 and earlier are now
deprecated or obsolete (as per SUN's documentation in system tuning);
IPC tuning is now done by using solaris 10 projects (/etc/projects
file).

Friends,

Fine tunning has been done in /etc/system also but no luck.

Following is systems setting:

We have set Net_BUFFER SIZE and
/usr/openv/netbackup/db/config/SIZE_DATA_BUFFERS = 131072
/usr/openv/netbackup/db/config/NUMBER_DATA_BUFFERS= 3072

Following is the kernel parameter of Solaris 10 OS
root@P075XMED01 # prtctl $$
-bash: prtctl: command not found
root@P075XMED01 # prctl $$
process: 15640: -bash
