1.How can you tell how much space is left on a given file system and how much space each of the file system's subdirectories take-up in UNIX and WIN NT ?
2.How do you tell what your machine name is and what is its IP address in UNIX and NT ?
3.You have 4 instances running on the same UNIX box. How can you determine which shared memory and semaphores are associated with which instance?
4.Illustrate how to determine the amount of physical CPUs a Unix Box possesses (LINUX and/or Solaris)
5. How do you increase the OS limitation for open files (LINUX and/or Solaris)?
I need answers to any or all of these above questions ASAP !!

I'll try to answer the Unix/Linux questions. Windows is not one of the platforms I would like to waste time on:
1. Use the df and du commands
2. uname -n and ifconfig -a
3. ipcs and SQL> oradebug SETMYPID followed by SQL> oradebug IPC
4. Solaris - prtdiag, Linux - cat /proc/cpuinfo
5. Solaris - set rlim_fd_max/rlim_fd_cur in /etc/system,
Linux - echo "16384" >> /proc/sys/kernel/file-max
Best regards.
Frank
