Session never expired If i closed client prompt

Hi,

I need a solution. I am using Putty/CRT to login in a AIX server from my windows machine. When i closed my putty/CRT prompt from windows client, server session is expire.

Ex. I have run a script to take RMAN backup from PUTTY/CRT command window, After closing command window RMAN backup failed to complete.

  • Solution Other than nohup, VNC screen.
    & Suppose i have logged out from server, But my command will running in backgrournd, After log in i want to see my previous command execution screen.

Thank you very much
