Oracle has issued a security bulletin this week, recommending customers consider workarounds to address a long-standing zero-day vulnerability in nearly all versions of its database management system.

 
The four-year-old Oracle database vulnerability became an issue last week when the researcher who discovered the flaw issued details and proof-of-concept code to carry out a “TNS listener poison attack.” Joxean Koret, a security researcher based in Spain, reported the vulnerability to Oracle in 2008. According to Oracle’s blog, last week Koret, “[had] mistakenly, assuming that the issue had been backported through the CPU… fully disclosed its details.”

# PCP (PID con Port)
# v1.10 08/10/2010 Sam Nelson sam @ unix.ms
#
# If you have a Solaris 8, 9 or 10 box and you can't
# install lsof, try this. It maps PIDS to ports and vice versa.
# It also shows you which peers are connected on which port.
# Wildcards are accepted for -p and -P options.

# Many thanks Daniel Trinkle trinkle @ cs.purdue.edu

1) Use your command prompt and type systeminfo | more

2) Press <enter> a few times until you see this information:-

Total Physical RAM
Available Physical RAM
PageFile In Use

Formula:
Total RAM usage = (Total Physical Memory – Available Physical Memory) + (Page File In Use – 250)
You should always be sure to have 80-100 MB of Physical RAM over your Total RAM usage or you will experience slow response from your computer
