dbca查看帮助：
[oracle@wen ~]$ dbca -help
1）、运行静默建库语句
[oracle@wen ~]$ dbca -silent -cloneTemplate -gdbName wen -sid wen -sysPassword oracle -systemPassword oracle -emConfiguration LOCAL -dbsnmpPassword oracle -sysmanPassword oracle -responseFile /home/oracle/dbca.rsp

将wen库运行的users改名：
SQL> select username,account_status from dba_users where account_status='OPEN';
USERNAME ACCOUNT_STATUS
------------------------------ --------------------------------
SYSTEM OPEN
SYS OPEN
SYSMAN OPEN
DBSNMP OPEN
MGMT_VIEW OPEN
2）使用模板建库
模板位置：
[oracle@wen ~]$ ls $ORACLE_HOME/assistants/dbca/templates/
Data_Warehouse.dbc example.dmp New_Database.dbt Seed_Database.dfb
example01.dfb General_Purpose.dbc Seed_Database.ctl
建库语句：
[oracle@wen ~]$ dbca -silent -createDatabase -templateName $ORACLE_HOME/assistants/dbca/templates/General_Purpose.dbc -gdbName wcw -sid wcw -responseFile NO_VALUE
或
[oracle@wen oradata]$ dbca -silent -createDatabase -templateName $ORACLE_HOME/assistants/dbca/templates/General_Purpose.dbc -gdbName wcw -sid wcw -emConfiguration LOCAL -dbsnmpPassword oracle -sysmanPassword oracle -responseFile NO_VALUE
静默删除数据库：
[oracle@wen oradata]$ dbca -silent -deleteDatabase -sourceDB wen

克隆数据库
1、通过已有的orcl库静默方式创建一个模板出来：
[oracle@wen ~]$ dbca -silent -createCloneTemplate -sourceSID orcl -templateName chavin
