Hi,

If speed/duplex settings are OK for NIC´s and switches and you can FTP some 
large files from/to Oracle and TSM servers with a reasonable speed. Then you 
have to monitor CPU, Disk I/O etc on both servers and switches...  To find a 
pattern and track down the problem.

Hi Akash
                We have found if you are using 100mb network for example you 
have to ensure that all interfaces are set to the same speed etc eg:

Host 100mb/Full switch port 100mb/Full and backup server 100mb/Full

Hope this helps
Cheers Mark

Subject: Backup

Hi all,

I am in very strange situation where my Oracle backup sometimes completes in
1 hour and sometimes it took only 16 minutes for same data.

On scrutinising the logs, it has been observed that it's the matter of network 
performance. Sometimes I am getting a speed of 1206kb/ps (data took
1 hour to backed up) and at 4506kb/ps completes in 16 minutes.

I am assuming this is the network issue and to be checked by networking guys.

Does anyone have faces this problem or any ideas about the same?

AIX - 4.3.3.11
Data - Oracle Files
Backup Software : TSM


Regards
Akash Jain
