[oracle@db-sys~]$ source .bash_profile

• 修改口令文件和参数文件的名称

[oracle@dbs]$ ls

hc_DBUA0.dat  hc_orcl.dat  init.ora  lkBOOK  lkBOOKS  lkMYDB  lkORCL  orapworcl  spfileorcl.ora

[oracle@dbs]$ pwd

/usr/local/oracle/product/11.2.0/db_1/dbs

[oracle@dbs]$ mv orapworcl orapwbook

[oracle@dbs]$ mv spfileorcl.ora spfilebook.ora

[oracle@dbs]$ ls

hc_DBUA0.dat  hc_orcl.dat  init.ora  lkBOOK  lkBOOKS  lkMYDB  lkORCL  orapwbook  spfilebook.ora

• 修改完成后启动实例，查看实例名称即可：

SQL> show parameter name;
