Errors in file /opt/Oracle/diag/rdbms/ndmcdb/NDMCDB/trace/NDMCDB_j000_11169.trc:
ORA-12012: error on auto execute of job 30
ORA-29283: invalid file operation
ORA-06512: at "SYS.UTL_FILE", line 41
ORA-06512: at "SYS.UTL_FILE", line 512
ORA-29283: invalid file operation
ORA-06512: at "NDMC.PROC_TODO_TASK", line 74
ORA-06512: at line 1
于是到数据库中查询：
Job Schema User Last Date Next Date Total Time B Interval Failures What
---------- ----------------- -------------------- -------------------- ---------- - ------------------------------ ---------- -------------------------
30 NDMC 01-Jan-4000 00:00:00 0 Y TRUNC(sysdate + 1) + 4/24 16 PROC_TODO_TASK;
现在这个Job已经不可用了。
根据日志中的提示，用PL/SQL Developer找到该存储过程：
定位到74行：
这里是要打开一个目录，那么这个PATH是在哪里定义的呢？
于是查看数据库：
SQL> col DIRECTORY_PATH for a50
SQL> col OWNER for a20
SQL> select * from dba_directories;
OWNER DIRECTORY_NAME DIRECTORY_PATH
-------------------- ------------------------------ --------------------------------------------------
SYS NDMIGEXPDIR2 /home/oracle/ndmig_expdpdata
SYS NDMIGEXPDIR /home/oracle/archive/ndmig/expdpdata
SYS BACK_MSG_LOGS_PATH /home/oracle/msgBackup/work
SYS UNSUB_DATA_PATH /home/oracle/backup/unsub_data
SYS SHARELOG /home/oracle/share/
SYS DISKPKGFILECATALOG /home/oracle/backup/pkg_incon_data/diskpkgfile
SYS LOGCATALOG /home/oracle/backup/pkg_incon_data
SYS DATA_PUMP_DIR /opt/oracle/product/11g/db/rdbms/log/
SYS ORACLE_OCM_CONFIG_DIR /opt/oracle/product/11g/db/ccr/state
那么确认系统中是否存在这个目录或是这个目录权限是否正确：
oracle@NDMCDB05:~> cd /home/oracle/backup/unsub_data
-bash: cd: /home/oracle/backup/unsub_data: No such file or directory
发现这个目录不存在，于是手工创建:
oracle@NDMCDB05:~> mkdir -p /home/oracle/backup/unsub_data
接着需要将job的属性修改正确：
问题解决！

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.
Can I install mysql on Windows 7
Apr 08, 2025 pm 03:21 PM
Yes, MySQL can be installed on Windows 7, and although Microsoft has stopped supporting Windows 7, MySQL is still compatible with it. However, the following points should be noted during the installation process: Download the MySQL installer for Windows. Select the appropriate version of MySQL (community or enterprise). Select the appropriate installation directory and character set during the installation process. Set the root user password and keep it properly. Connect to the database for testing. Note the compatibility and security issues on Windows 7, and it is recommended to upgrade to a supported operating system.
Explain InnoDB Full-Text Search capabilities.
Apr 02, 2025 pm 06:09 PM
InnoDB's full-text search capabilities are very powerful, which can significantly improve database query efficiency and ability to process large amounts of text data. 1) InnoDB implements full-text search through inverted indexing, supporting basic and advanced search queries. 2) Use MATCH and AGAINST keywords to search, support Boolean mode and phrase search. 3) Optimization methods include using word segmentation technology, periodic rebuilding of indexes and adjusting cache size to improve performance and accuracy.
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.
MySQL: Simple Concepts for Easy Learning
Apr 10, 2025 am 09:29 AM
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.
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.
The relationship between mysql user and database
Apr 08, 2025 pm 07:15 PM
In MySQL database, the relationship between the user and the database is defined by permissions and tables. The user has a username and password to access the database. Permissions are granted through the GRANT command, while the table is created by the CREATE TABLE command. To establish a relationship between a user and a database, you need to create a database, create a user, and then grant permissions.
RDS MySQL integration with Redshift zero ETL
Apr 08, 2025 pm 07:06 PM
Data Integration Simplification: AmazonRDSMySQL and Redshift's zero ETL integration Efficient data integration is at the heart of a data-driven organization. Traditional ETL (extract, convert, load) processes are complex and time-consuming, especially when integrating databases (such as AmazonRDSMySQL) with data warehouses (such as Redshift). However, AWS provides zero ETL integration solutions that have completely changed this situation, providing a simplified, near-real-time solution for data migration from RDSMySQL to Redshift. This article will dive into RDSMySQL zero ETL integration with Redshift, explaining how it works and the advantages it brings to data engineers and developers.
