The UNIVERSITY tablespace is currently open read/write.
The source and destination platforms have different endian formats.
Examine this list of actions:
1-Make the UNIVERSITY tablespace read-only on the source system.
2-Export the UNIVERSITY tablespace metadata using EXPDP.
3-Convert the UNIVERSITY tablespace data files to the destination platform format using RMAN on the source system.
4-Copy the UNIVERSITY tablespace data files to the destination system.
5-Copy the Data Pump dump set to the destination system.
6-Convert the UNIVERSITY tablespace data files to the destination platform format using RMAN on the destination system.
7-Import the UNIVERSITY tablespace metadata using IMPDP.
8-Make the UNIVERSITY tablespace read/write on the destination system.
Which is the minimum number of actions required, in the correct order, to transport the UNIVERSITY tablespace?
1, 2, 4, 5, 7, 8
1, 2, 4, 6, 7, 8
1, 2, 3, 4, 5, 7, 8

Contains two pluggable databases (PDBs), pdb1 and pdb2. You are
Connected to pdb2 as a common user with DBA privileges. The
Statistics_level parameter is PDB modifiable.
As the user sys, execute the following command on pdb2:
SQL> ALTER SYSTEM SET STATISTICS_LEVEL=ALL SID='*' SCOPE=SPFILE;
Which statement is true about the result of this command?
The statistics_level parameter is set to all when any of the PDBs is reopened.
The statistics_level parameter is set to all only for PDB2 when it is reopened.
The statistics_level parameter is set to all when the root database is restarted.
The statement is ignored because there is no SPFILE for a PDB.
Database. You want to know which change caused this performance
Difference. Which method or feature should you use?
Compare Period ADDM report
AWR Compare Period report
Active Session History (ASH) report
Taking a new snapshot and comparing it with a preserved snapshot.
SQL> ALTER DATABASE BACKUP CONTROLFILE TO TRACE;
What is the outcome?
It creates a binary backup of the control file.
It updates the alert log with the location and contents of the control file
It creates a file that contains SQL statements to re-create the control file.
It creates a file that contains RMAN scripts to create a duplicate database.
Database has significantly degraded. Sometimes you are not able to connect
To the instance because it hangs. You do not want to restart the database
Instance. How can you detect the cause of the degraded performance?
Enable Memory Access Mode, which reads performance data from SGA.
Use emergency monitoring to fetch data directly from SGA for analysis.
Run Automatic Database Diagnostic Monitor (ADDM) to fetch information
From the latest Automatic Workload Repository (AWR) snapshots.
Use Active Session History (ASH) data and hang analysis in regular
Performance monitoring,

User SCOTT has been granted the CREATE SESSION privilege and the MGR role.
Which two statements are true when a session logged in as SCOTT queries the SAL column in the view and the table?
DataisredactedfortheEMP.SALcolumnonlyiftheSCOTTsessiondoesnothavetheM
GR role set.
DataisredactedforEMP.SALcolumnonlyiftheSCOTTsessionhastheMGRroleset.
Data is never redacted for the EMP_VW.SAL column.
Data is redacted for the EMP_V.SAL column only if the SCOTT session has the
MGR role set.
Database instance is in ARCHIVELOG mode. The default location for the
Archived redo log files is the FRA.
Which two files are removed automatically if space is required in the FRA as

And SYSKM privilege to the password file?
Assign the appropriate operating system groups to SYSBACKUP, SYSDG,
SYSKM.
Grant SYSBACKUP, SYSDG, and SYSKM privileges to the intended users.
Re-create the password file with SYSBACKUP, SYSDG, and SYSKM privilege
And the FORCE argument set to No.

SQL>ALTER DATABASE BACKUP CONTROLFILE TO TRACE;
Which statement is true about the command?
It creates a copy of the control file and stores it in the location specified in the
Diagnostic_dest initialization parameter.
It creates a file that contains SQL statement to re-create the control file.
It updates the alert log file with the location and contents of the control file.
It creates a binary backup of the control file.
Media management interface (MMI).
Which two are true about the use of
The RMAN MMI?
You can use it to create proxy copies for database files.
You can use it to create proxy copies for entire file systems.
You can use it to create image copies for entire file systems.
You can use it to create image copies for database files.
You are managing this configuration:
1CDB1 is a container database.
2 PDB1 and PDB2 are two pluggable databases in CDB1.
3 USER1.EMP is a table in PDB1 and USER2.DEPT is a table in PDB2 .
CDB1 user SYS executes these commands after connecting successfully to
PDB2:
SQL> ALTER SESSION SET CONTAINER=pdb1;
Session altered.
SQL> INSERT INTO user1.emp VALUES (100, 'Alan' ,1) ;
1 row created.
SQL> INSERT INTO user1.emp VALUES (101, 'Ben' ,1) ;
1 row created.
SQL> ALTER SESSION SET CONTAINER=pdb2;
