为了学习,把数据库的verify_function功能打开,,自动将default概要文件的密码过期时间设置成60天,密码重用的天数为18000天,密码满足复杂性要求等等,关闭verify_function功能后,没有及时修改default概要文件,导致sysman和dbsnmp用户密码过期后,打开OEM界面直接报错如下图,其他部件均正常!

查看sysman和dbsnmp用户的状态均为密码过期,修改密码后重新登录OEM,依然报错如下图!

Oracle教程:OEM错误之ORA-28001

SQL> select username,account_status from dba_users where username='SYSMAN';
USERNAME                       ACCOUNT_STATUS
SYSMAN                         EXPIRED

SQL> alter user sysman identified by "123456";
User altered.

SQL> alter user dbsnmp identified by "123456";
User altered.


再次查询sysman和dbsnmp用户的状态,这次的状态为LOCKED(TIMED)
SQL> select username,account_status from dba_users where username='SYSMAN';
USERNAME                       ACCOUNT_STATUS
SYSMAN                         LOCKED(TIMED)

原因:
dbsnmp和sysman这两个用户和oem紧密相关,dbsnmp用户启动Oracle智能代理,用于收集oracle系统运行状态的相关数据,sysman是oem的超级管理员。如果配置了oem后,又使用alter user identified by ;修改了这两用户的口令,就会出现dbsnmp 和sysman  "LOCKED(TIMED)". 的情况。

解决方法:
还必须同步修改oem中记录的dbsnmp和sysman用户的口令。

$emca  -config  dbcontrol db

根据提示修改sysman和dbsnmp的口令即可。

When might a full table scan be faster than using an index in MySQL? When might a full table scan be faster than using an index in MySQL? Apr 09, 2025 am 12:05 AM

Full table scanning may be faster in MySQL than using indexes. Specific cases include: 1) the data volume is small; 2) when the query returns a large amount of data; 3) when the index column is not highly selective; 4) when the complex query. By analyzing query plans, optimizing indexes, avoiding over-index and regularly maintaining tables, you can make the best choices in practical applications.

Difference between clustered index and non-clustered index (secondary index) in InnoDB. Difference between clustered index and non-clustered index (secondary index) in InnoDB. Apr 02, 2025 pm 06:25 PM

The difference between clustered index and non-clustered index is: 1. Clustered index stores data rows in the index structure, which is suitable for querying by primary key and range. 2. The non-clustered index stores index key values ​​and pointers to data rows, and is suitable for non-primary key column queries.

The relationship between mysql user and database The relationship between mysql user and database Apr 08, 2025 pm 07:15 PM

Can mysql and mariadb coexist Can mysql and mariadb coexist Apr 08, 2025 pm 02:27 PM

MySQL and MariaDB can coexist, but need to be configured with caution. The key is to allocate different port numbers and data directories to each database, and adjust parameters such as memory allocation and cache size. Connection pooling, application configuration, and version differences also need to be considered and need to be carefully tested and planned to avoid pitfalls. Running two databases simultaneously can cause performance problems in situations where resources are limited.

Explain different types of MySQL indexes (B-Tree, Hash, Full-text, Spatial). Explain different types of MySQL indexes (B-Tree, Hash, Full-text, Spatial). Apr 02, 2025 pm 07:05 PM

MySQL supports four index types: B-Tree, Hash, Full-text, and Spatial. 1.B-Tree index is suitable for equal value search, range query and sorting. 2. Hash index is suitable for equal value searches, but does not support range query and sorting. 3. Full-text index is used for full-text search and is suitable for processing large amounts of text data. 4. Spatial index is used for geospatial data query and is suitable for GIS applications.
