（实践应用）Oracle 11g R2 测试schema生成

Oracle测试schema包含HR、SH等用户，在Oracle 11g R2下可以按照如下方式生成
1. 检查字符集，若不是US7ASCII，则要修改字符集，否则会在mkplug.sql restore的时候报错¹:

ERROR at line 1:
ORA-19583: conversation terminated due to error
ORA-19870: error while restoring backup piece
/opt/app/oracle/product/11.2.0/db_1/assistants/dbca/templates/example01.dfb
ORA-19615: some files not found in backup set
ORA-19613: datafile 6 not found in backup set
ORA-06512: at “SYS.DBMS_BACKUP_RESTORE”,line 5824
ORA-06512: at line 33

--检查字符集
SQL>select userenv('language') from dual;

若不是US7ASCII则修改字符集²

SQL>SHUTDOWN IMMEDIATE
SQL>STARTUP MOUNT;

SQL>ALTER SYSTEM ENABLE RESTRICTED SESSION;
SQL>ALTER SYSTEM SET JOB_QUEUE_PROCESSES=0;
SQL>ALTER SYSTEM SET AQ_TM_PROCESSES=0;
SQL>ALTER DATABASE OPEN;

SQL>ALTER DATABASE CHARACTER SET INTERNAL_USE US7ASCII;

SQL>SHUTDOWN IMMEDIATE;
SQL>STARTUP

2.运行mkplug.sql脚本，前7个参数是password，后4-5个参数(参数数量应该和具体版本有关），设置如下³

cd /u01/app/oracle/product/11.2.0/db_1/demo/schema

SQL>@?/demo/schema/mkplug.sql
·····
specify INPUT metadata import file as parameter 8:
       Enter value for 8: /u01/app/oracle/product/11.2.0/db_1/assistants/dbca/templates/example.dmp
specify INPUT database backup file for tablespace EXAMPLE as parameter 9:
        Enter value for 9: /u01/app/oracle/product/11.2.0/db_1/assistants/dbca/templates/example01.dfb
specify OUTPUT database file for tablespace EXAMPLE as parameter 10:
        Enter value for 10: /u01/app/oracle/oradata/skyHost/example01.dbf
specify OUTPUT log directory as parameter 11:
        Enter value for 11: /u01/app/oracle/product/11.2.0/db_1/demo/schema/log/
specify OUTPUT dump file directory as parameter 12:
        Enter value for 12: /u01/app/oracle/product/11.2.0/db_1/assistants/dbca/templates/
