修改oracle用户密码复杂度

全备数据库

create directory arcl_dir as '/bakdata';
grant read,write on directory orcl_dir to system;

expdp导出源库数据
su - oracle
#全库导出
expdp system/oracle directory=arcl_dir full=y dumpfile=expdpfull_arcl.%U.dmp logfile=expdpfull_arcl.log parallel=2 cluster=N

环境检查
sqlplus “/as sysdba”

select * from v$version;
select * from dba_profiles;

查看有无verify_function函数

select object_name from all_objects where object_type='FUNCTION' AND object_name='VERIFY_FUNTION';

没有verify_function函数要创建

SQL>@$ORACLE_HOME/rdbms/admin/utlpwdmg.sql
select * from dba_profiles;
alter system set resource_limit = true;
alter profile default limit password_verify_function verify_function; 
alter profile default limit password_lock_time 1/288;
alter profile default limit FAILED_LOGIN_ATTEMPTS 3;
alter profile default limit PASSWORD_LIFE_TIME 180;

检查

select * from dba_profiles;
SQL> select * from dba_profiles;
