吉⼤DB2实验5吉林⼤学DB2实验报告班级:姓名:学号:2. Connect to MUSICDB to activate the database.3. Examine your db cfg file for MUSICDB.How large are the log files? Is this amount in pages or bytes? Show your work below by printing screen and answer the question.4. How many primary log files will be allocated? When will these files be allocated?When the database is created, three log files are considered to be the main log files. DB2 will increase LOGFILSIZ by two pages to increase overhead, so there are three main log file (6 + 2) pages with a size of 4KB. (3 * (6 + 2) * 4KB) = 3 * 32KB = 96KB of space, which will be allocated to the main log.5. How many secondary log files will be allocated? When will these files beforward recovery.13. Now, list the contents of SQLOGDIR.Show your work below by printing screen.cd SQLOGDIRdir14. How many log files are in this directory? Does this match what you expected considering your configuration file? Why or why not?There are three log files in this directory. This matches the number of main log files in the configuration. This is appropriate because the main log file is allocated when the database is created.15. Increase the quantity in the STOCK table by 1 but do not commit the update. If you are not certain how to turn off auto-commit, check the solutions.Show your work below by printing screen.16. If you encounter an error, go to the next question. If you did NOT encounter any error, decrease the quantity in the STOCK table by 1.Show your work below by printing screen.17. What did you observe? What was the SQL code you received?The statement failed with a SQL code of -964. (You may see the trigger identified as causing an error.)18. Issue a command to retrieve help on the SQL code. Why did the statement fail? Show your work below by printing screen. The transaction log of the database is full. Because all the space in the transaction log is being used, there is no extra space.19. Since the unit of work could not complete successfully, issue a rollback. Show your work below by printing screen.20. From your telnet session, determine the number of log files allocated at this point. How many are there?521. What accounts for the additional files?When circular logging is used and the main log file is filled, the auxiliary log file will be allocated. The attached log file is a secondary log file22. Change to your home directory in your Command window.cd /23. From your telnet session, create a directory that will contain backups of your database: mkdir restoreCreatedSection 2 - Backup/Restore Support with Circular Logging1. Connect to your musicdb database from the new command window.Show your work below by printing screen.2. Attempt to perform an online backup of your MUSICDB database to the directory of C:\restore. Were you successful in trying to specify an online backup? Explain why or why not.Show your work below by printing screen and answer the question.In the GUI, DB2 prevents you from selecting the online radio button when trying to perform a backup. On the command line, an error message SQL2413 was returned. Online backup allows other transactions to change the database at the same time. Therefore, only databases configured for rollforward recovery can support online backup. Otherwise, the integrity of the database will be threatened3. Attempt to perform an offline backup instead.Show your work below by printing screen.4. Did the backup complete successfully? What did the message say?The backup was not completed. The message says that you cannot perform a backup now because the database is currently in use (SQL1035N). In DB2 9, offline backup can be completed. This indicates that the application was forced to leave the database.5. In order to take an offline backup, do you think that exclusive use of the database is required? Who is currently connectedto the database?Offline backup requires exclusive use of the database. This is the way to ensure integrity. The application connected to the database is another telnet session previously connected to the database.6. Resolve the apparent problem by forcing all applications to end.Show your work below by printing screen.Just execute db2 force applications all.7. Now try your backup again.Show your work below by printing screen.8. Was the backup successful this time?Successful backup9. The timestamp for a backup image is necessary for restore if you are using the RESTORE command rather than the GUI DB2 Control Center, and multiple images reside in a given source.When the backup is targeted to disk, the name of the file itself will reflect the timestamp. When tape or TSM managed devices are used, the header in the backup image will contain this information.10. Look at the backup information through the LIST BACKUP command. Remember that you have a previous backup froman early lab (LOAD lab). Issue the list backup command with the ALL keyword.Show your work below by printing screen.11. Is the timestamp available as part of this information?Time stamp is part of the information provided12. Record the start timestamp of the backup.20200421122549 is the timestamp of this backup13. How many table spaces are included in this backup?This complete database backup contains 11 table spaces.14. Instead of using the keyword ALL, it is possible to restrict the output of the LIST BACKUP command via a timestamp specification or by object name specification.Issue a request to get just the backups for today.You may wish to request online help for this command.Show your work below by printing screen.15. The history information regarding backups is maintained by the database manager and can become extensive if it is never removed. Use the ? command to invoke the online help facility to identify a command that can be used to manage the amount of history information retained. Write the name of the command you believe would give you the capability to eliminate old history information.Show your work below by printing screen.The PRUNE HISTORY command can be used to manage backup history information.16. From your Command Window, examine the file naming convention used for your backup.Show your work below by printing screen.cd \cd restoredir17. The backup image reflects the same data that is currently in your MUSICDB database since you have not issued any SQL to change data since the backup was taken. Select the artist's name and album titles for artist number (ARTNO) 77. Show your work below by printing screen.18. Change the name of th e artist 77 to “Melanie and the Mechanics” and the album title of ITEMNO 261 to “Unmaterial Girl”. Show your work below by printing screen.19. Execute a join between ARTISTS and ALBUMS for ARTNO 77 and document the data as it now appears. This reflects a change that occurred after your backup.Show your work below by printing screen.20. Assume the disk containing the MUSICDB database failed. You now have the task to restore the backup image that was made.Show your work below by printing screen.21. First make sure there are no applications are connected to the database. Show your work below by printing screen.。

db2 执行计划

db2 执行计划DB2执行计划。
DB2是一个关系数据库管理系统,它的执行计划是指DB2优化器生成的用于执行SQL查询的计划。
执行计划决定了如何访问表中的数据,以及如何执行连接、筛选和排序等操作。
一个好的执行计划可以显著提高查询的性能,而一个不好的执行计划则可能导致性能问题。
执行计划的生成是一个复杂的过程,它涉及到DB2优化器对查询进行分析、选择合适的访问路径、确定连接顺序、选择合适的访问方法等。
在这个过程中,DB2会考虑到表的大小、索引的选择性、统计信息、系统资源等因素,以及用户给定的查询条件。
在DB2中,我们可以通过多种方式来查看执行计划,比如使用EXPLAIN语句、使用Visual Explain工具、使用db2exfmt命令等。
接下来,我们将介绍如何使用这些方法来查看执行计划。
首先,我们可以使用EXPLAIN语句来查看执行计划。
EXPLAIN语句可以在执行SQL查询之前加上,它会告诉DB2生成执行计划,但不会真正执行查询。
执行计划会被保存在一个特殊的表中,我们可以使用SELECT语句来查看这个表的内容,从而获得执行计划的信息。
这种方法比较直接,但是需要对SQL查询进行修改,因此并不适用于所有场景。
其次,我们可以使用Visual Explain工具来查看执行计划。
Visual Explain是一个图形化的工具,它可以将执行计划以图形的方式展现出来,使我们更直观地理解执行计划。
我们可以通过将SQL查询粘贴到Visual Explain中,然后点击“Explain”按钮来生成执行计划,并查看其图形化展示。
这种方法比较直观,适用于对图形化展示感兴趣的用户。
最后,我们还可以使用db2exfmt命令来查看执行计划。
db2exfmt是一个命令行工具,它可以将执行计划以文本的方式展示出来。
我们可以在命令行中输入db2exfmt加上SQL查询来生成执行计划,并查看其文本展示。
这种方法比较灵活,适用于对文本展示感兴趣的用户。
