If you are using 11g, then you want to use interval partitioning. Oracle will create a new partition every month for that months data. However, you might find that partitioning by day will work better, since you are working with audit data you might only look at the last day or last couple of days when querying the data. Having smaller level of granularity when used with partition pruning will likely lead to fewer io operator per query. Hence more efficient queries. You might also want to partition by month and sub partition by day. This will make it easier to drop a month at a time when you truncate old data, assuming that you do. You should be able to find plenty of examples for what you want on the web.

NAME

       holidays - prime/nonprime table for the accounting system

SYNOPSIS

       /etc/acct/holidays

DESCRIPTION

       The   /etc/acct/holidays file describes which hours are considered prime time and which days  are holidays.  Holidays and weekends are con-
       sidered non-prime time hours.  /etc/acct/holidays is used by the accounting system.

       All lines beginning with an "*" are comments.

       The  /etc/acct/holidays file consists of two sections.  The first non-comment line defines the current year and the start time of prime and
       non-prime time hours, in the form:

       current_year	 prime_start	  non_prime_start

       The remaining non-comment lines define the holidays in the  form:

       month/day     company_holiday

       Of these two fields, only the  month/day is actually used by  the accounting system programs.

       The  /etc/acct/holidays file must be updated each year.

EXAMPLES

       Example 1: Example of the /etc/acct/holidays file.
