客户的Oracle 11.2.0.3 RAC环境自动运行的JOB报错ORA-29280。
详细错误信息为：
Sat Sep 15 05:59:59 2012
VKRM started with pid=54, OS id=32622
Sat Sep 15 06:00:09 2012
Errors in file /opt/app/oracle/diag/rdbms/orcl/orcl1/trace/orcl1_j001_32634.trc:
ORA-12012: error on auto execute of job "ORACLE_OCM"."MGMT_CONFIG_JOB_2_1"
ORA-29280: invalid directory path
ORA-06512: at "ORACLE_OCM.MGMT_DB_LL_METRICS", line 2436
ORA-06512: at line 1
这个问题在升级之前的11.2.0.2版本上没有出现过，，显然这是升级到11.2.0.3带来的bug。而报错的JOB所属用户ORACLE_OCM是Oracle配置管理的专属用户。根据文档"ORA-12012: error on auto execute of job ORACLE_OCM.MGMT_CONFIG_JOB_2_1" And "ORA-29280: invalid directory path" In Database AlertLog [ID 1453959.1]，导致问题的原因是数据库升级到11.2.0.3后，Oracle会启用自动OCM collection，在这个过程中Oracle尝试使用目录ORACLE_OCM_CONFIG_DIR2，但这个目录在创建过程中并未建立。
解决该问题并不复杂，对于不需要使用配置管理器的用户而言，可以简单的DISABLE掉这个JOB，或者直接将ORACLE_OCM用户删除：
exec dbms_scheduler.disable('ORACLE_OCM.MGMT_CONFIG_JOB')
exec dbms_scheduler.disable('ORACLE_OCM.MGMT_STATS_CONFIG_JOB')
如果需要使用配置管理器，可以通过ORACLE_HOME/ccr/admin/scripts/installCCRSQL脚本来重新设置配置管理器。如果上面的脚本缺失，可以通过先执行ORACLE_HOME/ccr/bin/setupCCR脚本的方式来进行配置。

MySQL's Role: Databases in Web Applications
Apr 17, 2025 am 12:23 AM
The main role of MySQL in web applications is to store and manage data. 1.MySQL efficiently processes user information, product catalogs, transaction records and other data. 2. Through SQL query, developers can extract information from the database to generate dynamic content. 3.MySQL works based on the client-server model to ensure acceptable query speed.
Explain the role of InnoDB redo logs and undo logs.
Apr 15, 2025 am 12:16 AM
InnoDB uses redologs and undologs to ensure data consistency and reliability. 1.redologs record data page modification to ensure crash recovery and transaction persistence. 2.undologs records the original data value and supports transaction rollback and MVCC.
MySQL: An Introduction to the World's Most Popular Database
Apr 12, 2025 am 12:18 AM
MySQL is an open source relational database management system, mainly used to store and retrieve data quickly and reliably. Its working principle includes client requests, query resolution, execution of queries and return results. Examples of usage include creating tables, inserting and querying data, and advanced features such as JOIN operations. Common errors involve SQL syntax, data types, and permissions, and optimization suggestions include the use of indexes, optimized queries, and partitioning of tables.
MySQL's Place: Databases and Programming
Apr 13, 2025 am 12:18 AM
MySQL's position in databases and programming is very important. It is an open source relational database management system that is widely used in various application scenarios. 1) MySQL provides efficient data storage, organization and retrieval functions, supporting Web, mobile and enterprise-level systems. 2) It uses a client-server architecture, supports multiple storage engines and index optimization. 3) Basic usages include creating tables and inserting data, and advanced usages involve multi-table JOINs and complex queries. 4) Frequently asked questions such as SQL syntax errors and performance issues can be debugged through the EXPLAIN command and slow query log. 5) Performance optimization methods include rational use of indexes, optimized query and use of caches. Best practices include using transactions and PreparedStatemen
Why Use MySQL? Benefits and Advantages
Apr 12, 2025 am 12:17 AM
MySQL is chosen for its performance, reliability, ease of use, and community support. 1.MySQL provides efficient data storage and retrieval functions, supporting multiple data types and advanced query operations. 2. Adopt client-server architecture and multiple storage engines to support transaction and query optimization. 3. Easy to use, supports a variety of operating systems and programming languages. 4. Have strong community support and provide rich resources and solutions.
MySQL vs. Other Programming Languages: A Comparison
Apr 19, 2025 am 12:22 AM
Compared with other programming languages, MySQL is mainly used to store and manage data, while other languages such as Python, Java, and C are used for logical processing and application development. MySQL is known for its high performance, scalability and cross-platform support, suitable for data management needs, while other languages have advantages in their respective fields such as data analytics, enterprise applications, and system programming.
MySQL: From Small Businesses to Large Enterprises
Apr 13, 2025 am 12:17 AM
MySQL is suitable for small and large enterprises. 1) Small businesses can use MySQL for basic data management, such as storing customer information. 2) Large enterprises can use MySQL to process massive data and complex business logic to optimize query performance and transaction processing.
How does MySQL index cardinality affect query performance?
Apr 14, 2025 am 12:18 AM
MySQL index cardinality has a significant impact on query performance: 1. High cardinality index can more effectively narrow the data range and improve query efficiency; 2. Low cardinality index may lead to full table scanning and reduce query performance; 3. In joint index, high cardinality sequences should be placed in front to optimize query.
