Your multitenant container (CDB) contains two pluggable databases (PDB), HR_PDB
and ACCOUNTS_PDB, both of which use the CDB tablespace. The temp
file is called temp01.tmp.
A user issues a query on a table on one of the PDBs and receives the following
ERROR at line 1:
ORA-01565: error in identifying file `/u01/app/oracle/oradata/CDB1/temp01.tmp
ORA-27037: unable to obtain file status
Identify two ways to rectify the error.
A. Add a new temp file to the temporary tablespace and drop the temp file that
that produced the error.
B. Shut down the database instance, restore the temp01.tmp file from the
backup, and then restart the database.
C. Take the temporary tablespace offline, recover the missing temp file by
applying redo logs, and then bring the temporary tablespace online.
D. Shutdown the database instance, restore and recover the temp file from the
backup, and then open the database with RESETLOGS.
E. Shut down the database instance and then restart the CDB and PDBs.
Correct Answer: A,E
* Because temp files cannot be backed up and because no redo is ever generated
for them, RMAN never restores or recovers temp files. RMAN does track the
names of temp files, but only so that it can automatically re-create them when
* If you use RMAN in a Data Guard environment, then RMAN transparently converts
primary control files to standby control files and vice versa. RMAN
automatically updates file names for data files, online redo logs, standby redo
logs, and temp files when you issue RESTORE and RECOVER.
Examine the following commands for redefining a table with Virtual Private
Database (VPD) policies:
Which two statements are true about redefining the table?
A. All the triggers for the table are disabled without changing any of the
column names or column types in the table.
B. The primary key constraint on the EMPLOYEES table is disabled during
C. VPD policies are copied from the original table to the new table during
D. You must copy the VPD policies manually from the original table to the new
table during online redefinition.
Correct Answer: B,C
C (not D): CONS_VPD_AUTO
Used to indicate to copy VPD policies automatically
/ The DBMS_RLS package contains the fine-grained access control administrative
interface, which is used to implement Virtual Private Database
(VPD).DBMS_RLS is available with the Enterprise Edition only.
* CONS_USE_PK and CONS_USE_ROWID are constants used as input to the
"options_flag" parameter in both the START_REDEF_TABLE Procedure and
CAN_REDEF_TABLE Procedure. CONS_USE_ROWID is used to indicate that the
redefinition should be done using rowids while CONS_USE_PK implies that
the redefinition should be done using primary keys or pseudo-primary keys
(which are unique keys with all component columns having NOT NULL constraints).
To achieve online redefinition, incrementally maintainable local materialized
views are used. These logs keep track of the changes to the master tables and
used by the materialized views during refresh synchronization.
* START_REDEF_TABLE Procedure
Prior to calling this procedure, you must manually create an empty interim
table (in the same schema as the table to be redefined) with the desired attributes
post-redefinition table, and then call this procedure to initiate the
Which two statements are true about the use of the procedures listed in the
A. The procedure may be used for some components to relocate component data to
the SYSAUX tablespace from its current tablespace.
B. The procedure may be used for some components to relocate component data
from the SYSAUX tablespace to another tablespace.
C. All the components may be moved into SYSAUX tablespace.
D. All the components may be moved from the SYSAUX tablespace.
Correct Answer: A,B
Which statement is true about Oracle Net Listener?
A. It acts as the listening endpoint for the Oracle database instance for all
local and non-local user connections.
B. A single listener can service only one database instance and multiple remote
C. Service registration with the listener is performed by the process monitor
(PMON) process of each database instance.
D. The listener.ora configuration file must be configured with one or more
listening protocol addresses to allow remote users to connect to a database
E. The listener.ora configuration file must be located in the
Correct Answer: C
Supported services, that is, the services to which the listener forwards client
requests, can be configured in the listener.ora file or this information can be
dynamically registered with the listener. This dynamic registration feature is
called service registration. The registration is performed by the PMON
instance background process--of each database instance that has the necessary
configuration in the database initialization parameter file. Dynamic service
registration does not require any configuration in the listener.ora file.
Not B: Service registration reduces the need for the SID_LIST_listener_name
parameter setting, which specifies information about the databases served by
listener, in the listener.ora file.
* Oracle Net Listener is a separate process that runs on the database server
computer. It receives incoming client connection requests and manages the
these requests to the database server.
* A remote listener is a listener residing on one computer that redirects
connections to a database instance on another computer. Remote listeners are
used in an Oracle Real Application Clusters (Oracle RAC) environment. You can
configure registration to remote listeners, such as in the case of Oracle RAC,
dedicated server or shared server environments.
You are administering a database stored in Automatic Storage Management (ASM).
You use RMAN to back up the database and the MD_BACKUP command to
back up the ASM metadata regularly. You lost an ASM disk group DG1 due to
In which three ways can you re-create the lost disk group and restore the data?
A. Use the MD_RESTORE command to restore metadata for an existing disk group by
passing the existing disk group name as an input parameter and use
RMAN to restore the data.
B. Use the MKDG command to restore the disk group with the same configuration
as the backed-up disk group and data on the disk group.
C. Use the MD_RESTORE command to restore the disk group with the changed disk
group specification, failure group specification, name, and other attributes
and use RMAN to restore the data.
D. Use the MKDG command to restore the disk group with the same configuration
as the backed-up disk group name and same set of disks and failure group
configuration, and use RMAN to restore the data.
E. Use the MD_RESTORE command to restore both the metadata and data for the
failed disk group.
F. Use the MKDG command to add a new disk group DG1 with the same or different
specifications for failure group and other attributes and use RMAN to restore
Correct Answer: A,C,F
AC (not E):
md_restore command allows you to restore a disk group from the metadata created
by the md_backup The
md_restore cant restore data, only metadata.
