Oracle Database Discussions

Hello,



I have installed the oracle 10g standard edition, but during installation i have not modified the password management.



I am able to run the isqlplus tool in the browser,but when i type username as <strong>sys@orcl2 and password sysdba</strong>,i am getting the error as

<strong>ERROR - ORA-12154: TNS:could not resolve the connect identifier specified</strong> and



when i type <strong>username as scott and passwd tiger</strong> ,i am getting error as

<strong>ERROR - ORA-28000: the account is locked</strong>.

I am leaving the connect identifier column blank in both the cases.



I have set the default password as sysdba for all the 4 users ( sys,sysdba,syspoer...) during installation.



please help me.



Thanks,

khan
