The role of various Oracle services under WIN7

Previously learned Oracle, the computer has been installed, but also did not uninstall, but the service is set to manually close the incident, this time again with Oracle found a lot of things have forgotten, see so many services, the start of that do not know .....

Oracle ORCL VSS Writer service:oracle Volume Mapping copy write service, VSS (Volume Shadow Copy service) enables the creation of high-fidelity point-in-time images of storage infrastructure (such as disks, arrays, etc.), i.e. mapped copies ( Shadow copy). It can create a mapped copy on multiple volumes or on a single volume without affecting the system's system performance. (must not be started)

Oracledbconsoleorcl:oracle Database Console service, ORCL is the instance identity of Oracle, and the default instance is ORCL. You need to start this service when you run Enterprise Manager (Enterprise Management Manager OEM). (must not be started)

Oraclejobschedulerorcl:oracle Job scheduling (timer) service, ORCL is the Oracle instance identity. (must not be started)

Oraclemtsrecoveryservice: Service-side control. The service allows the database to act as a resource manager for transactions in a Microsoft Transaction Server MTS, com/com+ object, and distributed environment. (must not be started)

Oracleoradb11g_home1clragent:oracle part of the database. Net Extension Service. (must not be started)

Oracleoradb11g_home1tnslistener: Listener service, the service is only needed when the database requires remote access. (must not be started)

ORACLESERVICEORCL: The database service (DB instance), which is the Oracle Core service, is the basis for database startup, and only if the service is started, the Oracle database can start normally. (Must Start)

If you are using only Oracle's sql*plus in development, you can only start ORACLESERVICEORCL, and if you use a third-party tool such as PL/SQL developer, Oracleoradb11g_home1tnslis Tener service is also to be opened. ORACLEDBCONSOLEORCL is a web-based EM must be turned on, and the rest of the service is seldom used.

Note: ORCL is the database instance name, the default database is ORCL, you can create other, that is, the oracleservice+ database name.
