dbconsole一直是我不怎么推荐的oracle工具,但是总有一些客户使用,这里对于dbconsole中sysman用户状态,密码修改做了一些基本的测试
sysman用户被锁
SQL> alter user sysman account lock; User altered.
重启dbconsole
[oracle@localhost ~]$ emctl stop dbconsole

部分错误日志提示（这里可以明显dbconsole无法正常使用是由于sysman被锁）
解锁sysman用户
SQL> alter user sysman account unlock; User altered.

sysman解锁之后重启dbconsole恢复正常
修改sysman密码

由于dbconsole的密码存储在配置文件中，修改sysman密码，而配置文件的没有修改，因此使用错误是syman密码登录，超过了profile里面设置的10次，导致用户被锁.
解决sysman密码不对导致异常问题
[oracle@localhost ~]$ emctl stop dbconsole

通过人工修改$ORACLE_HOME/localhost_sid/sysman/config/emoms.properties文件中的oracle.sysman.eml.mntr.emdRepPwd=密码，oracle.sysman.eml.mntr.emdRepPwdEncrypted=false实现修改密码
[oracle@localhost config]$ grep emdRepPwd emoms.properties|grep -v emdRepPwdSeed oracle.sysman.eml.mntr.emdRepPwd=aa537afcbab41e05 oracle.sysman.eml.mntr.emdRepPwdEncrypted=TRUE
dbconsole重启之后，密码又重新被修改为加密方式,在11.2之前修改sysman密码，注意要同步修改emoms.properties中相关密码信息
sysman修改密码( 11.2 and higher)
