you will need to change the following line if you use dual NIC’s (as in the case of our RAC systems) in /usr/etc/upsd.conf

LISTEN localhost

If the server crashes while there are active nxclient connections nxclient will continue to detect the stale connection and will not allow you to connect. The easy way to get around this is by stopping the statistics daemon for NX:

/usr/NX/bin/nxstat stop

It is a good idea to restart it after you successfully login:

/usr/NX/bin/nxstat start

install rlwrap (available from http://utopia.knoware.nl/~hlub/rlwrap/)

then add this to the bash_profile:

alias sqlplus=’rlwrap sqlplus’

change ‘default’ to ’size=Xg’ in /etc/fstab

Then remount the filesystem

mount -o remount /dev/shm
