Consider listening to listener.ora

It is not necessary to specify the service name of the listening in the listening configuration file listener.ora (it is also not specified after installing Oracle10g). Normally, as long as the database is started, there is no problem for the client to connect to the database, but sometimes repeated startup and shutdown will also lead to ORA-12514 errors.

Since there is no listener specified in listener.ora, we can specify the instance name of the listener in the listener.ora file so that the problem should be able to connect.

The steps are as follows:

In the oracle server Oracle installation directory (mine in E:\ Oracle10g, everyone's different, according to their own situation to find) Network/admin directory to find listener.ora my figure below

# listener.ora Network Configuration File: e:\ Oracle10g\ network\ admin\ listener.ora

# Generated by Oracle configuration tools.

SID_LIST_LISTENER =

(SID_LIST =

(SID_DESC =

(SID_NAME = PLSExtProc)

(ORACLE_HOME = E:\ Oracle10g)

(PROGRAM = extproc)

)

(SID_DESC =

(GLOBAL_DBNAME = ORCL)

(ORACLE_HOME = E:\ Oracle10g)

(SID_NAME = ORCL)

)

)

LISTENER =

(DESCRIPTION_LIST =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = IPC) (KEY = EXTPROC1))

(ADDRESS = (PROTOCOL = TCP) (HOST = onest) (PORT = 1521))

)

)

The red one is the part I added, and ORCL is the instance name of the monitor.
