Services in ORACLE

[learn]

Hello,
I have two questions and I will be glad if somebody can answer them accordingly and if possible with some explanations.

1.In oracle what is a SERVICE NAME? Is it supposed to be the name of the database or it's different?

2. On NT, the service name can be found in SERVICES in the control panel. At times it's specified in the init.ora file. How can I find the service name in UNIX if it's not specified in the init.ora file?

thanks.

a service name is devided into 2:
1) the unique identifier of a service provider on a client machine. i.e service
DB1( ADDRESS = ....
CONNECT_DATA = (SID = ...))

this service is your connection to the remote database from a client.

2) on windows nt a service is the component responsible for the Oracle Instance (OracleServiceXXXX)
and for the database (OracleStartXXXX)
