1.sqlplus / as sysdba后使用select instance_name,status from v$instance后出錯：

ERROR:
ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
進程 ID: 0
會話 ID: 0 序列號: 0

解決辦法：先關閉，然后重新啟動

      $ export ORACLE_SID=
      
        YOUR_TARGET_ORACLE_INSTANCE

$ sqlplus 
      
      /
      
         as sysdba


      
      >
      
        shutdown immediate;


      
      >startup;
    

?
