Oracle字符集转换

由ZHS16GBK转换成AL32UTF8

shutdown immediate;
STARTUP MOUNT;
ALTER SESSION SET SQL_TRACE=TRUE;
ALTER SYSTEM ENABLE RESTRICTED SESSION;
ALTER SYSTEM SET JOB_QUEUE_PROCESSES=0;
ALTER SYSTEM SET AQ_TM_PROCESSES=0;
ALTER DATAB ASE  OPEN;

alter database character set INTERNAL_CONVERT AL32UTF8;

不会出现超集错误。
