nect
Regardless of whether you are using network information or internal
tables, getting the raw data is just the first step. Once this data is accessible,
the following steps are required to support desired monitoring:
1.
Continuously collect this information through interception or
polling
2.
Save this information to some kind of repository
3.
Use reporting tools to create usable reports and monitors that can
support ad hoc queries, filters, and aggregation
4.
Create a baseline for what is allowed and what is normal
5.
Use alerting tools to warn you of divergence from the baseline
3.4
Remove unnecessary network libraries
Clients connecting to the database can use various networking protocols.
Because there are many networks and protocols, most databases can be
accessed using more than one client-server mechanism. While today's net-
works are almost always TCP/IP networks, 15 years ago the networking
world was far more fragmented, and databases had to support many more
