$cd $ORACLE_HOME
$cd bin
$./sqlplus /nolog
SQL> conn / as sysdba;
SQL> shutdown immediate;
SQL> startup mount
SQL> ALTER SYSTEM ENABLE RESTRICTED SESSION;
SQL> ALTER SYSTEM SET JOB_QUEUE_PROCESSES=;
SQL> ALTER SYSTEM SET AQ_TM_PROCESSES=;
SQL>ALTER DATABASE OPEN;

SQL> ALTER DATABASE character set INTERNAL_USE ZHS16GBK;
