After successful installation of Oracle 11g, there are a total of 7 services,
The meaning of these seven services are:
1. Oracle ORCL VSS Writer Service：
Oracle Volume Shadow Copy Service, VSS (Volume Shadow Copy Service) enables storage infrastructure devices (such as disks, arrays, etc.) to create high-fidelity point-in-time images, that is, shadow copies. It can create mapped copies on multiple volumes or a single volume without affecting the system performance of the system. (not required to start)
2. OracleDBConsoleorcl: Oracle database console service, orcl is the instance identifier of Oracle, and the default instance is orcl. This service needs to be started when running Enterprise Manager (Enterprise Manager OEM). (not required to start)
3. OracleJobSchedulerORCL: Oracle job scheduling (timer) service, ORCL is the Oracle instance identifier. (not required to start)
4. OracleMTSRecoveryService: server control. This service allows the
database
act as a resource manager for
Microsoft
Transaction Server MTS, COM/COM+ objects and transactions in a distributed environment. (not required to start)
5. OracleOraDb11g_home1ClrAgent: Part of the Oracle Database .NET extension service. (not required to start)
6. OracleOraDb11g_home1TNSListener: Listener service, the service is only needed when the database needs remote access. (It is not necessary to start, and there will be a detailed explanation below).
7. OracleServiceORCL: database service (database instance), which is the core service of Oracle. This service is the basis for database startup. Only when this service is started, the Oracle database can be started normally. (must be activated)
For beginners, if you only use the sql*plus that comes with Oracle, you only need to start OracleServiceORCL. If you use third-party tools such as PL/SQL Developer, the OracleOraDb11g_home1TNSListener service should also be enabled. OracleDBConsoleorcl must be enabled to enter
web -based EM, and other services are rarely used.
Note:
ORCL is the database instance name, the default database is ORCL, you can create other, namely OracleService + database name.
