common mistake in OSB installation: Prerequisite

Prerequisites for Installing Oracle Secure Backup on Linux and UNIX
The prerequisites for installing Oracle Secure Backup on Linux and UNIX
operating
systems are:
¦ Each host must have a network connection with a static IP address and run
TCP/IP (Transmission Control Protocol/Internet Protocol).
¦ The uncompress utility must be installed on your system.

Note: If the uncompress utility is not installed on your system, then
you can create an uncompress symbolic link pointing to the gunzip
utility with the following command:
ln -s /bin/gunzip uncompress

¦ You must have the Small Computer System Interface (SCSI) parameters
for each
tape drive and tape library attached to your Linux or UNIX media server. You
can determine them using the procedures described in Appendix C,
"Determining
Linux and UNIX SCSI Parameters". You need this information when creating a
device special file for each tape device.
¦ You must be able to log in to each host with root privileges to
perform the
installation.
