Oracle 10g New
Features Overview
The overall
focus of the Oracle 10g new features is of course grid
computing, the idea of which is the introduction of computing power
available on demand much like electricity. Or as Giga Research put it: "In basic terms grids are clusters
of computers or servers that are linked together enabling the pooling
of computing resources" ("Defining Grid
Computing", Giga Research, August 2002).
The main
driver for this focus in Oracle 10g is the fact that
many if not most organisations have more computing resources
than they actually need most of the time, due to systems being sized to
handle the peak load which might occur just once per year. In fact
research by Forrester concluded "Globally,
firms spend more than $49 billion a year on servers and CIOs report
that server utilization is 60% or less". (Forrester Research, April 2002)
The specific Oracle 10g new features that take advantage of the grid
are Real Application Clusters (not entirely new but enhanced from
Oracle 9i), Automatic Storage Management (ASM) new in Oracle 10g,
Oracle Streams and Oracle Resource Manager (again, both of these have
been enhanced from Oracle 9i).
Underneath the grid computing umbrella, the Oracle 10g new features can
be organised into 5 broad categories:
- Manageability/automation - in other words
decreasing the amount of time spent on routine tasks to leave more time
for strategic tasks
- Common Manageability Infrastructure
- Storage Enhancements
- Space Management
- Other Manageability Enhancements
- Human Error Correction (including flashback
database)
- Availability
- Recovery through resetlogs
- Backup and recovery
- Data Guard
- Online redefinition
- LogMiner
- Performance
- Resource Manager
- Wait interface enhancements
- End to end application testing
- SQL tuning advisor
- Business Intelligence/Data Warehousing
- Materialized view refresh and query
rewrite
- Asynchronous change data capture
- Materialized view refresh and query
rewrite
- Application Development
Tying
everything together is Oracle Enterprise Manager (OEM) which has also
been enhanced for Oracle 10g.
OEM in Oracle 10g is installed at the same time as the database and now
has a web-based architecture. This eliminates the need to install a
separate application to access the OEM console and means the console
can also be accessed from a web-enabled PDA via EM2GO. OEM also
provides fully functional administration and monitoring after
database creation.
The main enhancements to Enterprise Manager for Oracle 10g are in terms
of improved ease of use, reduced implementation costs and management of
the whole Oracle environment including Oracle Application
Server, business applications, storage, network, operating system and
hardware.
