19/125

19


In this practice, you create a duplicate database.


20/125

20

Practice 6-1: Create a Dupl icate Database

In this practice, you use RMAN to create a duplicate database on the same host as yourdatabase.

1) Create an Oracle password file for your auxiliary instance.

2) Use Oracle Net Manager to create an entry calledAUXDB in the t nsnames. orafile.

3) Create an initialization parameter file for the auxiliary instance.

4) Start the auxiliary instance in NOMOUNT mode using the i ni t AUX. or a file.

5) Create a server parameter file (SPFILE).

6) Verify that your target database (orc l database) is mounted or open.

7) Start RMAN with a connection to the target database (orcl ) and the auxiliaryinstance.

8) Create the duplicate database by executing the DUPLI CATE command.

9) Use SQL*Plus to log in to your AUX database and execute a query against theHR. REGI ONS table.

10)Now that you have completed the test recovery by creating a duplicate database, shutdown the aux instance.

11)Change your ORACLE_SI D to orc l in preparation for later practices.


21/125

21


In this practice, you use tablespace point-in-time recovery to recover from unwanted changes to your

database.


22/125

22

Practice 7-1: Use Tablespace Point-in-time Recovery

1) Execute the l ab_07_01_01_01. sh script to export the HR schema.

2) Execute the l ab_07_01_02_02. sql script to create a new tablespace and a new

user in your database.

3) Execute the l ab_07_01_03_01. sh script to populate the new tablespace with acopy of the data from the HR schema.Note: The import should complete successfully. You will receive error messages

because the import excludes the COUNTRI ES, REGI ONS, and LOCATI ONS tables.These messages can be ignored.

4) Create a backup of your database using RMAN.

5) Record the current SCN: ____________

6) Record the current time.

7) Execute the l ab_07_01_07_01. sql script to query the HRTEST. EMPLOYEEStable and view information about employees in department 60.Make note of the highest salary that is displayed: ________

8) Execute the l ab_07_01_08_01. sql script to update the salaries for theemployees in department 60 and note the highest salary displayed.

Highest salary: _____________

9) You now want to perform TSPITR for the HRTEST tablespace to return it to the stateprior to the updates. Execute the l ab_07_01_09_01. sql script to determine

whether there are any dependencies that will prevent the TSPITR operation.

10)You can use Enterprise Manager Database Control or RMAN command line toperform tablespace point-in-time recovery.

11)Verify that the HRTEST tablespace is online.

12)Verify that the SALARY columns in HRTEST. EMPLOYEES for the employees indepartment 60 contain the correct values.

13)Execute the l ab_07_01_13_02. sql script to add a constraint to theHRTEST. DEPARTMENTS table.

14)Assume you need to perform TSPITR on the HRTEST tablespace again. Execute thel ab_07_01_14_02. sql query to determine whether there are any dependenciesoutside the recovery set.

15)If you wanted to complete the tablespace point-in-time recovery for the HRTEST tablespacenow, what would you need to do?


23/125

23

Note: You will not perform another tablespace point-in-recovery in this practice.

You would need to disable the DEPT_LOC_I D_FK constraint that was added to yourHRTEST. DEPARTMENTS table or you would need to add


24/125

24


In this practice, you create a recovery catalog in your instructors database and register

your database in the recovery catalog.


25/125

25

Practice 8-1: Create the Recovery Catalog and Regis ter theDatabase

The tablespace for the recovery catalog and the recovery catalog owner have been created

in the instructor database. The tablespaces are named RCTS01 RCTS12. The users are

named RCUSER01 RCUSER12.

1) Connect to the recovery catalog database (instructors database) with the appropriaterecovery catalog owner name (if you are using PC01, connect as RCUSER01) usingRMAN. Create the recovery catalog in your assigned tablespace. (If you are using

PC01, your assigned tablespace is RCTS01.) The service name is RCDB.

2) Using RMAN, connect to your target database and the recovery catalog database.

3) Using RMAN, execute the command to resynchronize the control file and recovery catalog. Whathappens? Why?

4) Register the target database in the recovery catalog. You can use RMAN commandline orEnterprise Manager for this step.

5) Create an RMAN script named whol e_backup to make a whole database backup. Do notexecute the whole_backup script at this time.

6) Use the PRI NT command to query the recovery catalog and verify the creation of yourwhol e_backup script.

7) In preparation for later practices, use RMAN to unregister your database from therecovery catalog.


26/125

26


In this practice, you monitor the progress of your RMAN backup jobs.


27/125

27

Practice 9-1: Use SQL to Monitor the Progress of RMANBackups

1) Invoke RMAN and delete all obsolete backups.

2) Open a second terminal window. Change to the l abs directory. Invoke SQL*Plusand connect as SYSDBA. You will use this second session to monitor a databasebackup.

3) Return to your first terminal window. In your RMAN session, begin a whole databasebackup.

4) Use your SQL*Plus session to monitor the progress of the whole database backup by

querying the V$SESSI ON_LONGOPS view. By using this view you can determinewhether the backup is progressing normally or hanging. If the backup is progressing

normally, theTI ME_REMAI NI NG column should be decreasing. Execute thel ab_09_01_04_01. sql script to query V$SESSI ON_LONGOPS.


28/125

28

Practice 9-2: Use Enterprise Manager to Monitor RMAN Jobs

You can easily monitor RMAN jobs in Enterprise Manager.

1) Start Enterprise Manager and log in as SYS/ ORACLE as SYSDBA.

2) Delete obsolete backups.

3) Start a whole database backup
