Oracle Service description and CMD start-up command

After successfully installing Oracle 11g, a total of 7 services
The meanings of these seven services are:
1. 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 (Shadow copy) of storage infrastructure devices such as disks, arrays, and so on. 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)
2. 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)
3. ORACLEJOBSCHEDULERORCL:
Oracle Job scheduling (timer) service, ORCL is an Oracle instance identity. (must not be started)
4. Oraclemtsrecoveryservice:

5. Oracleoradb11g_home1clragent:
Oracle Database
. NET extension services. (must not be started)
6. Oracleoradb11g_home1tnslistener:
Listener service, the service is only required if the database requires remote access. (not required to start, detailed below).
7. ORACLESERVICEORCL:
The database service (DB instance), which is the Oracle Core service, is the basis for database startup, and the Oracle database starts normally only if the service is started. (Must Start)
For beginners, if you only use Oracle's own sql*plus, just start ORACLESERVICEORCL, and if you use a third-party tool such as PL/SQL developer, Oracleoradb11g_ Home1tnslistener 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.
