Oracle 10g分区表的自动维护
oracle 10g分区表不支持自动化管理,一般都要手动创建分区,手动删除。今天给大家带来了一个自动化管理表空间的脚本。
Oracle 10g分区表不支持自动化管理,一般都要手动创建分区,,手动删除。今天给大家带来了一个自动化管理表空间的脚本。
本脚本主要由3个部分组成:sys_ConfigTable.sql、sys_pro_AddAndDropPartition.sql、sys_pro_MergeTable.sql
1、sys_ConfigTable.sql 主要创建了一张配置表:这里填写具体要自动维护的表名、保存天数、每天分区的个数等等;
2、sys_pro_AddAndDropPartition.sql 这个用来自动增加表分区,删除过期分区;
3、sys_pro_MergeTable.sql 等每天的分区大于1时,我们合并旧的分区,并重建失效的索引。
1、sys_ConfigTable.sql

To query the Oracle tablespace size, follow the following steps: Determine the tablespace name by running the query: SELECT tablespace_name FROM dba_tablespaces; Query the tablespace size by running the query: SELECT sum(bytes) AS total_size, sum(bytes_free) AS available_space, sum(bytes) - sum(bytes_free) AS used_space FROM dba_data_files WHERE tablespace_

There are the following methods to get time in Oracle: CURRENT_TIMESTAMP: Returns the current system time, accurate to seconds. SYSTIMESTAMP: More accurate than CURRENT_TIMESTAMP, to nanoseconds. SYSDATE: Returns the current system date, excluding the time part. TO_CHAR(SYSDATE, 'YYY-MM-DD HH24:MI:SS'): Converts the current system date and time to a specific format. EXTRACT: Extracts a specific part from a time value, such as a year, month, or hour.

There are three ways to view instance names in Oracle: use the "sqlplus" and "select instance_name from v$instance;" commands on the command line. Use the "show instance_name;" command in SQL*Plus. Check environment variables (ORACLE_SID on Linux) through the operating system's Task Manager, Oracle Enterprise Manager, or through the operating system.

Oracle View Encryption allows you to encrypt data in the view, thereby enhancing the security of sensitive information. The steps include: 1) creating the master encryption key (MEk); 2) creating an encrypted view, specifying the view and MEk to be encrypted; 3) authorizing users to access the encrypted view. How encrypted views work: When a user querys for an encrypted view, Oracle uses MEk to decrypt data, ensuring that only authorized users can access readable data.

Uninstall method for Oracle installation failure: Close Oracle service, delete Oracle program files and registry keys, uninstall Oracle environment variables, and restart the computer. If the uninstall fails, you can uninstall manually using the Oracle Universal Uninstall Tool.

Data import method: 1. Use the SQLLoader utility: prepare data files, create control files, and run SQLLoader; 2. Use the IMP/EXP tool: export data, import data. Tip: 1. Recommended SQL*Loader for big data sets; 2. The target table should exist and the column definition matches; 3. After importing, data integrity needs to be verified.

To create a user in Oracle, follow these steps: Create a new user using the CREATE USER statement. Grant the necessary permissions using the GRANT statement. Optional: Use the RESOURCE statement to set the quota. Configure other options such as default roles and temporary tablespaces.

Oracle Invalid numeric errors may be caused by data type mismatch, numeric overflow, data conversion errors, or data corruption. Troubleshooting steps include checking data types, detecting digital overflows, checking data conversions, checking data corruption, and exploring other possible solutions such as configuring the NLS_NUMERIC_CHARACTERS parameter and enabling data verification logging.
