What Operating System and version do you have?
What version of Oracle are you using?
Because Oracle makes extensive use of Shared Memory segments and most modern versions of unix use paged memory it is remarkably difficult to find out how much memory Oracle is using. The Oracle installation manuals are very good on the subject of configuring unix and Oracle for a given memory size. It is very important to know your Oracle Database Block Size because many Oracle startup parameters are in units of Blocks.
You can find out a lot from Oracle itself.

Convert::NLS_DATE_FORMAT(3pm) User Contributed Perl Documentation Convert::NLS_DATE_FORMAT(3pm)NAME
Convert::NLS_DATE_FORMAT - Convert Oracle NLS_DATE_FORMAT <-> strftime Format Strings
SYNOPSIS
use Convert::NLS_DATE_FORMAT qw(oracle2posix posix2oracle);
my $strptime = oracle2posix($NLS_DATE_FORMAT);
$NLS_DATE_FORMAT = posix2oracle($strftime);
DESCRIPTION
Convert Oracle's NLS_DATE_FORMAT string into a strptime format string, or the reverse.
Functions
oracle2posix
Takes an Oracle NLS_DATE_FORMAT string and converts it into formatting string compatible with "strftime" or "strptime".
my $format = oracle2posix('YYYY-MM-DD HH24:MI:SS'); # '%Y-%m-%d %H:%M:%S'
Character sequences that should not be translated may be enclosed within double quotes, as specified in the Oracle documentation.
my $format = oracle2posix('YYYY-MM-DD"T"HH24:MI:SS'); # '%Y-%m-%dT%H:%M:%S'
posix2oracle
Takes a "strftime" or "strptime" formatting string and converts it into an Oracle NLS_DATE_FORMAT string. It is possible to create
strings which Oracle will not accept as valid NLS_DATE_FORMAT strings.
my $format = posix2oracle('%Y-%m-%d %H:%M:%S'); # 'YYYY-MM-DD HH24:MI:SS'
EXPORT
None by default. "oracle2posix" and "posix2oracle" when asked.
