Hi Friends,
I thought I will get some inputs on my following implementation. The
requirement is to audit some data changes with in the system.( Oracle 10.2
on RHEL 4.7 )
The audit is required in a sense that, the before images of data and
information of who changed the data is required. I have looked at options
like Oracle Auditing,FGA and so. But this cannot give me audit for the
data changes,when and who changed.
The first thing that comes into my mind are using triggers . Another
option is using log miner. I have successfully tested it out with both of
these approaches. The environment is like
1 ) For some critical tables for which audit is required triggers were
written ( ours is an OLTP application )
2 ) For some non critical tables, log miner which was called by a stored
procedure which runs at certain periods is used.
3 ) audit data is stored in a different schema , with same table names as
in base schema.
I would like to know your thoughts on this.
Thank You,
Kind Regards,
Sreejith Nair
