I started 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 database.
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:

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

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.

Last attempt to solve this problem was to 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.
