When Oracle9i is installed under the
Windows operating system, it installs a number of services–some of
which are configured to start whenever Windows starts. While Oracle
is running under Windows, it consumes a lot of resources and may
not always be needed. You may find it useful to be able to shut
down the database completely and quickly, without going through the
Windows graphical interfaces.

As long as you have admin privileges, you can
control any of the following services using the command net start to start a service
and net stop to stop the
service. In Windows XP, you can change the Startup Type parameter
by going to the Services control panel, locating the service you
wish to disable (OracleOraHome…), double-clicking on it to view
the service properties, and changing the Startup Type property from
Automatic to Manual.

The only service that needs to be running to be
able to work with a database locally is the OracleServiceORCL
service (where ORCL is the SID). This service will also
automatically start up and shut down the database (using shutdown
abort). If you installed a database, the default startup type will
be Automatic. If you’re primarily accessing a remote database, you
can switch this to Manual startup type.

The OracleOraHome92HTTPServer service (where
OraHome92 is the name of the Oracle Home) is the Apache server that
you automatically install when you install Oracle. You generally
only need it to access Web pages in the Oracle Apache directories,
such as JSP and modplsql pages.

The OracleOraHome92TNSListener service is only
needed if the database will be accessed remotely (either from
another host or locally via a SQL*Net network protocol). You can
access local databases without this service.

The OracleOraHome92ClientCache service caches
Oracle Names data for connecting to remote databases. This service
is normally configured for Manual startup type. However, it isn’t
necessary to run this service unless you have an Oracle Names
server running somewhere.

There are four more services that are necessary
for the Oracle Enterprise Manager: OracleOraHome92Agent (the
Intelligent Agent), which monitors the database and Enterprise
Manager requests and defaults to an Automatic startup type.
OracleOraHome92SNMPPeerEncapsulator and
OracleOraHome92SNMPPeerMasterAgent, which handle the Secure Network
Management Protocol service. OracleOraHome92PagingServer, which
sends alerts out through an alphanumeric pager via a modem or

The OracleMTSRecoveryService, which is
optional, allows your database to be used as a resource manager for
the Microsoft Transaction Server, COM/COM+ objects, and
transactions in a distributed environment.

If you only use your database occasionally, you
can create simple batch jobs to start up and shut down your
database with a double-click, without going through the graphical

  1. Save a shortcut somewhere to launch these
    files automatically.
  2. Set all your Oracle services to manual to
    avoid starting up with Windows boot.
