I start with Oracle DB. On Windows Server 2003 I installed Oracle Database 10g Express Edition and then I also installed PL SQL Developer.
I tried log on via PL SQL Developer to XE databse.
I use this credentials:
- Username: system
- Password: password is correct :)
- Database: XE
I got this error: ORA-12528. So I google it and tried this solution: http://www.dba-oracle.com/sf_ora_12528_tns_listener_all_appropriate_instances_are_blocking_new_connection_tips_bc1.htm:
SQL> conn system as sysdba
Enter password:
Connected.

LSNRCTL> stop

The command completed successfully
and again start listener

Then I tried again connect to XE database via PL SQL Developer but I got error ORA 12514.
I checked the lister log file (listener.log), here is it output:

Here I put configs.

XE =

(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = XE)
)

(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC_FOR_XE))

(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
)
)
ORACLR_CONNECTION_DATA =

)

(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = C:\oraclexe\app\oracle\product\10.2.0\server)

)
(SID_DESC =
(SID_NAME = CLRExtProc)
(ORACLE_HOME = C:\oraclexe\app\oracle\product\10.2.0\server)

LISTENER =

(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC_FOR_XE))
(ADDRESS = (PROTOCOL = TCP)(HOST = jan)(PORT = 1521))
)
)
DEFAULT_SERVICE_LISTENER = (XE)
I tried made a change in tsname.ora and change SERVICE_NAME to SID
XE =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = jan)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SID = XE)
)
)
But I got error:
**ORA-12505** TNS: listener does not currently know of SID given in connect descriptor
I remove change (SID = XE => SERVICE_NAME=XE) in tsname.ora and finaly I checked status of listener with command.
LSNRCTL> stat
Result is here:
Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC_FOR_XE)))

I tried restarted OracleServiceXE (Control panel > Adminstrative Toolls > Services>)
Lastt attempt to solve this problem was connect to XE via cmd.
SQL> conn system/jano@XE
ERROR:
ORA-12528: TNS:listener: all appropriate instances are blocking new connections
Nothing works. I can not connect to XE.
This is my first time when I deal with Oracle DB. What is root of problem and how can solve this issue.
Thank you for cooperation.
