在Oracle数据库操纵中,登录Oracle账号时提示失败,并且Oracle账号频繁被锁定,本文将介绍如何解决此问题
在Oracle数据库操纵中,登录Oracle账号时提示失败,并且Oracle账号频繁被锁定。造成此故障的原因是什么呢?本文就介绍了这一过程,经由过程慢慢排查我们就能找到该故障的原因了。下面记录下查找这个题目的步调。
1. 找到账号被锁按时候
哄骗sqlplus或者sqldeveloper,查询账号被锁定的时候,相干语句如下:
--批改当前会话的日期显示格局
alter session set nls_date_format = ""yyyy-MM-dd hh24:mi:ss"";
--查询被锁定账号的锁按时候
username,lock_date dba_users where username like ""TRSEKPV65_DEMO"";
比如这里的查询到的锁按时候为:20:03:03
2. 找到oracle的安装目次
项目组常识库的oracle安装路径为:C:\devsoftware\oracle11g
3. 找到监听日记
找到
C:\devsoftware\oracle11g\diag\tnslsnr\DEV2-216\listener\trace\listener.log文件,该文件会记录oracle的一些跟踪信息
4. 查看监听日记
找到该文件后,发明很大,无法用editplus打开。把该文件上传到linux机械或者在windows机械高低载一个tail.exe法度,履行tail -20 listener.log号令,查看该文件的最后20行内容。
5. 定位题目
按照上方查询到的时候,在日记中找到对应的时候地位,可以定位到当前时候Oracle所履行的操纵。
01-8月 -2011 20:03:35 * (CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=portalteam)(CID=(PROGRAM=D:\TRS\TRSGateway4.6\gwserver_x64\TrsAgent.exe)(HOST=DEV2-216)(USER=Administrator))) * (ADDRESS=(PROTOCOL=tcp)(HOST=fe80::e816:9e03:60ac:fdaa%11)(PORT=13678)) * establish * portalteam * 0
6. 总结
从上边可以看到,造成Oracle的账号被锁定的原因是由” TrsAgent.exe”过程造成的。细心一想,本来批改了暗码,没有批改GateWay的登录信息,所以造成了该账号登录Oracle经常失败,因为我们设备了Oracle的最大容许登录错误次数为10,所以跨越10次错误后账号将被锁定。

In database optimization, indexing strategies should be selected according to query requirements: 1. When the query involves multiple columns and the order of conditions is fixed, use composite indexes; 2. When the query involves multiple columns but the order of conditions is not fixed, use multiple single-column indexes. Composite indexes are suitable for optimizing multi-column queries, while single-column indexes are suitable for single-column queries.

To optimize MySQL slow query, slowquerylog and performance_schema need to be used: 1. Enable slowquerylog and set thresholds to record slow query; 2. Use performance_schema to analyze query execution details, find out performance bottlenecks and optimize.

MySQL and SQL are essential skills for developers. 1.MySQL is an open source relational database management system, and SQL is the standard language used to manage and operate databases. 2.MySQL supports multiple storage engines through efficient data storage and retrieval functions, and SQL completes complex data operations through simple statements. 3. Examples of usage include basic queries and advanced queries, such as filtering and sorting by condition. 4. Common errors include syntax errors and performance issues, which can be optimized by checking SQL statements and using EXPLAIN commands. 5. Performance optimization techniques include using indexes, avoiding full table scanning, optimizing JOIN operations and improving code readability.

MySQL asynchronous master-slave replication enables data synchronization through binlog, improving read performance and high availability. 1) The master server record changes to binlog; 2) The slave server reads binlog through I/O threads; 3) The server SQL thread applies binlog to synchronize data.

MySQL is an open source relational database management system. 1) Create database and tables: Use the CREATEDATABASE and CREATETABLE commands. 2) Basic operations: INSERT, UPDATE, DELETE and SELECT. 3) Advanced operations: JOIN, subquery and transaction processing. 4) Debugging skills: Check syntax, data type and permissions. 5) Optimization suggestions: Use indexes, avoid SELECT* and use transactions.

The installation and basic operations of MySQL include: 1. Download and install MySQL, set the root user password; 2. Use SQL commands to create databases and tables, such as CREATEDATABASE and CREATETABLE; 3. Execute CRUD operations, use INSERT, SELECT, UPDATE, DELETE commands; 4. Create indexes and stored procedures to optimize performance and implement complex logic. With these steps, you can build and manage MySQL databases from scratch.

InnoDBBufferPool improves the performance of MySQL databases by loading data and index pages into memory. 1) The data page is loaded into the BufferPool to reduce disk I/O. 2) Dirty pages are marked and refreshed to disk regularly. 3) LRU algorithm management data page elimination. 4) The read-out mechanism loads the possible data pages in advance.

MySQL is suitable for beginners because it is simple to install, powerful and easy to manage data. 1. Simple installation and configuration, suitable for a variety of operating systems. 2. Support basic operations such as creating databases and tables, inserting, querying, updating and deleting data. 3. Provide advanced functions such as JOIN operations and subqueries. 4. Performance can be improved through indexing, query optimization and table partitioning. 5. Support backup, recovery and security measures to ensure data security and consistency.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
