Re: Disk Backup runs slow.
Hi Uday
The box is up for 77 days , so I was thinking whether you are talking of bouncing the application/database or the box. Also you might considering increasing dbc_max . What tis teh value of Maxdsiz.

Time name pid Data-VSS Shmem-VSS Other-VSS

Sample output running it at 1min interval on my machine. If you look at proc_mem_leak file it defined the threshold for VSS to 30MB by default, meaning it'll only list processes with more than 30MB of VSS. Obviously you can change this to capture a wider range of processes by editing proc_mem_leak and change "VSSthereshold". If you notice the above output the number doesn't change and realistically it should not change much, a significant growth over time will most likely be the suspect.

Re: Disk Backup runs slow.
Hi Uday,
Performance issue is the difficult points to resolve. So it could be any kind of bottlenecks : cpu, memory, disks and/or network.
1. Use the *time* command after a reboot and to measure the time variation for 2 days.
2. Is there any new applications or new releases on your system. Perhaps there is bad process consuming resources.
3. Check if any swap activities.
4. Are you using HP AutoRaid ? if yes, ensure that you are not on Raid 5. Some shutdown procedures are cleaning the system from huge log and temporary files. and after start up these files start growing ! Passing from Raid 0+1 to Raid 5 which is too slow.
5. If you have GlancePlus, Mesure Ware Agent and Perf View, this will allow you to know where you are wasting these plainty of time.
6. if not :
ipcs
iostat
vmstat
sar
netstat
and redirect them to logfiles and analyse them.
Good luck
Magdi
