Conectando o Oracle XE DB / Oracle Database 10g Express

Question

Eu comecei com o Oracle DB. No Windows Server 2003, instalei o Oracle Database 10g Express Edition e também instalei o PL SQL Developer.

Eu tentei fazer logon via PL SQL Developer para o banco de dados XE.

Eu uso essas credenciais:

• Nome de usuário: sistema
• Senha: a senha está correta:)
• Banco de dados: XE

Eu recebi este erro: ORA-12528 . Então eu pesquisei e tentei esta solução: link :

SQL> conn system as sysdba
Enter password:
Connected.

SQL> $ lsnrctl


LSNRCTL> stop
Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC_FOR_XE)))
The command completed successfully

e novamente iniciar o ouvinte

LSNRCTL> start
Starting tnslsnr: please wait...

Depois tentei conectar-me novamente ao banco de dados XE via PL SQL Developer, mas recebi o erro ORA 12514 .

Eu verifiquei o arquivo de log do ouvinte ( listener.log ), aqui está a saída:

System parameter file is C:\oraclexe\app\oracle\product.2.0\server\network\admin\listener.ora

Aqui eu coloco as configurações.

tnsname.ora

XE =
 (DESCRIPTION =
   (ADDRESS = (PROTOCOL = TCP)(HOST = jan)(PORT = 1521))
   (CONNECT_DATA =
     (SERVER = DEDICATED)
     (SERVICE_NAME = XE)
   )
 )
EXTPROC_CONNECTION_DATA =
 (DESCRIPTION =
   (ADDRESS_LIST =
     (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC_FOR_XE))
   )
   (CONNECT_DATA =
     (SID = PLSExtProc)
     (PRESENTATION = RO)
   )
 )
ORACLR_CONNECTION_DATA =
 (DESCRIPTION =
   (ADDRESS_LIST =
     (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC_FOR_XE))
   )
   (CONNECT_DATA =
     (SID = CLRExtProc)
     (PRESENTATION = RO)
   )
 )

listener.ora

SID_LIST_LISTENER =
 (SID_LIST =
   (SID_DESC =
     (SID_NAME = PLSExtProc)
     (ORACLE_HOME = C:\oraclexe\app\oracle\product.2.0\server)
     (PROGRAM = extproc)
   )
   (SID_DESC =
     (SID_NAME = CLRExtProc)
     (ORACLE_HOME = C:\oraclexe\app\oracle\product.2.0\server)
     (PROGRAM = extproc)
   )
 )

LISTENER =
 (DESCRIPTION_LIST =
   (DESCRIPTION =
     (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC_FOR_XE))
     (ADDRESS = (PROTOCOL = TCP)(HOST = jan)(PORT = 1521))
   )
 )

DEFAULT_SERVICE_LISTENER = (XE)

Eu tentei fazer uma alteração no tsname.ora e mudar o SERVICE_NAME para o SID

XE =
 (DESCRIPTION =
   (ADDRESS = (PROTOCOL = TCP)(HOST = jan)(PORT = 1521))
   (CONNECT_DATA =
     (SERVER = DEDICATED)
     (SID = XE)
   )
 )

Mas recebi um erro:

**ORA-12505** TNS: listener does not currently know of SID given in connect descriptor

Eu removi change (SID = XE = > SERVICE_NAME = XE) em tsname.ora e finalmente verifiquei o status do listener com o comando.

LSNRCTL> stat

O resultado está aqui:

Tentei reiniciado o OracleServiceXE (Painel de controle > Toolls administrativos > Serviços >)

A última tentativa para resolver este problema foi conectar-se ao XE via cmd.

SQL> conn system/jano@XE
ERROR:
ORA-12528: TNS:listener: all appropriate instances are blocking new connections

Nada funciona. Eu não consigo me conectar ao XE.

Esta é a primeira vez que ligo com o Oracle DB. Qual é a raiz do problema e como pode resolver esse problema.

Obrigado pela cooperação.

uma vez, desative todas as suas conexões de rede, reinicie o PC / Server e tente efetuar login. se tiver êxito, ative todas as suas conexões de rede.
