Hello all, recently I Installed Oracle 10g XE on my Windows XP PC.
I tried ran this command (Charachter set was not OK):
ALTER SYSTEM SET NLS_LANGUAGE = 'AMERICAN_AMERICA.IW8PC1507' SCOPE=SPFILE;
and since then I cant connect to my DB, all i'm getting is:
ORA-12514: TNS:listener does not currently know of service requested in connectdescriptor
I tried to do everything the Oracle 10g libraries says, but they all reffer to the Net Services Administrator's Guide and more stuff that are not supported in the XE.
I cant even see the connect page of the Oracle XE Management!!
please try to help me if you can.
