[Oracle] oracle 11g备份到10g
11g备份,导入10g的时候会抛错,直接阻止导入。 但是有时候还必须得把11g的数据库导入到10g,我今天就遇到了这种情况。 一开始只是把11g中的表全部备份,成功导入10g。但是缺少视图、存储过程等。一个个sql创建累死人,方法太笨。请教了一下资深DBA,重新备

但是有时候还必须得把11g的数据库导入到10g,我今天就遇到了这种情况。
一开始只是把11g中的表全部备份,成功导入10g。但是缺少视图、存储过程等。一个个sql创建累死人,方法太笨。请教了一下资深DBA,重新备份,重新导入,成功。
现在把我导入操作的全过程记录下来,希望可以方便更多的人!
一、在11g服务器上,使用expdp命令备份数据
EXPDP USERID='user/password'schemas=hsrep directory=DATA_PUMP_DIR dumpfile=aa.dmp logfile=aa.log version=10.2.0.1.0
其中,红色文字部分是根据需要改写的地方。例如我的sys密码是sys,数据库sid是orcl,要到出的用户名是hsrep,要导入到10.2.0.1.0版本的Oracle数据库中去。aa.dmp和aa.log将会在11g的dpdump目录中生成,例如我的11g装在了E盘下面,于是aa.dmp将会在E:\app\Administrator\admin\cuc\dpdump目录下被生成。
二、在10g服务器上,使用impdp命令恢复数据
准备工作:1.建库2.建表空间3.建用户并授权4.将aa.dmp拷贝到10g的dpdump目录下
IMPDP USERID='user/password' schemas=hserp directory=DATA_PUMP_DIR dumpfile=aa.dmp logfile=aa.log version=10.2.0.1.0
其中红色部分是根据需要改写的地方。例如我的sys密码是sys,数据库sid是orcl,要导入用户名为hsrep,要导入到10.2.0.1.0版本的Oracle数据库中去。aa.log将会在10g的dpdump目录中生成。

注意:导入和导出的用户必须一致!

The retention period of Oracle database logs depends on the log type and configuration, including: Redo logs: determined by the maximum size configured with the "LOG_ARCHIVE_DEST" parameter. Archived redo logs: Determined by the maximum size configured by the "DB_RECOVERY_FILE_DEST_SIZE" parameter. Online redo logs: not archived, lost when the database is restarted, and the retention period is consistent with the instance running time. Audit log: Configured by the "AUDIT_TRAIL" parameter, retained for 30 days by default.

The function in Oracle to calculate the number of days between two dates is DATEDIFF(). The specific usage is as follows: Specify the time interval unit: interval (such as day, month, year) Specify two date values: date1 and date2DATEDIFF(interval, date1, date2) Return the difference in days

The Oracle database startup sequence is: 1. Check the preconditions; 2. Start the listener; 3. Start the database instance; 4. Wait for the database to open; 5. Connect to the database; 6. Verify the database status; 7. Enable the service (if necessary ); 8. Test the connection.

Backing up and restoring a MySQL database in PHP can be achieved by following these steps: Back up the database: Use the mysqldump command to dump the database into a SQL file. Restore database: Use the mysql command to restore the database from SQL files.

The amount of memory required by Oracle depends on database size, activity level, and required performance level: for storing data buffers, index buffers, executing SQL statements, and managing the data dictionary cache. The exact amount is affected by database size, activity level, and required performance level. Best practices include setting the appropriate SGA size, sizing SGA components, using AMM, and monitoring memory usage.

The INTERVAL data type in Oracle is used to represent time intervals. The syntax is INTERVAL <precision> <unit>. You can use addition, subtraction, multiplication and division operations to operate INTERVAL, which is suitable for scenarios such as storing time data and calculating date differences.

To find the number of occurrences of a character in Oracle, perform the following steps: Get the total length of a string; Get the length of the substring in which a character occurs; Count the number of occurrences of a character by subtracting the substring length from the total length.

The method of replacing strings in Oracle is to use the REPLACE function. The syntax of this function is: REPLACE(string, search_string, replace_string). Usage steps: 1. Identify the substring to be replaced; 2. Determine the new string to replace the substring; 3. Use the REPLACE function to replace. Advanced usage includes: multiple replacements, case sensitivity, special character replacement, etc.
