dbconsole和sysman用户

发表于 2017 年 11 月 27 日 由 惜分飞

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）

sysman解锁之后重启dbconsole恢复正常
修改sysman密码

SQL> alter user sysman identified by xifenfei;

User altered.

SQL> select account_status from dba_users where username='SYSMAN';

ACCOUNT_STATUS
--------------------------------
OPEN

ACCOUNT_STATUS

LOCKED(TIMED)

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)

Oracle dbconsole 引起ORA-00020

发表于 2017 年 11 月 1 日 由 惜分飞

以前遇到一个客户是win环境,突然发现dbconsole发起大量会话进程，导致数据库的process不足.这次在一个客户的adg环境中,也发现了类似情况
ora-00020

这个是刚刚部署的adg库,没有任何业务,不应该出现这类情况,分析是哪些进程连接了数据库
java
这里可以确定是由于java进程创建了大量的oracle连接,进一步分析java进程是什么
dbconsole
这里比较明显,是由于em的java发起的数据库大量连接,停止掉dbconsole
stop_em
em停止掉之后,进一步观察oracle恢复,发现已经恢复正常
ok
这个问题应该是一个bug,没有具体去查询mos,使用dbconsole还是需要慎重
