- chetanTo changing database name you have to use create controlfile set database statement.Perform below steps.
Consider that we have database which name is "TEST"
1.Backup controlfile to trace
C:\Documents and Settings\chinar>set ORACLE_SID=TEST
C:\Documents and Settings\chinar>sqlplus "sys/sm as sysdba"
