You are enabling the Automatic Shared Memory Management feature in the Oracle Database 10g to ensure that the important memory structures of the System Global Area (SGA) are automatically adjusted depending on the database workload.

第4题:
Which three resource plan parameters are used to enable Automatic Consumer Group Switching to estimate job execution times automatically, and to perform a switch to a low priority consumer group before they are initiated?()
第5题:
You set the undo pool resource plan directive for the consumer group named DSS_USERS that is assigned to the DAY_SHIFT plan. The database users, SCOTT and BLAKE, belong to the DSS_USERS resource group. The user, SCOTT, initiates a database session and executes a batch operation that inserts millions of rows into the HISTORY table. Which two options are true if the total undo space allocated to the DSS_USERS group exceeds the value specified in the undo pool resource plan directive?()
第6题:
Which three resources might be prioritized between competing pluggable databases when creating amultitenant container database plan (CDB plan) using Oracle Database Resource Manager?()
第7题:
The parallel degree limit for DB_GRP will be the minimum of all the incoming values.
The parallel degree limit for DB_GRP will be the maximum of all the incoming values.
The maximum estimated execution time for DB_GRP would be the most nonrestrictive of all incoming values.
If a session switched from the DB_GRP consumer group to another consumer group because it exceeded the prescribed switch time, then that session would not execute if the active session pool for the new consumer group was full.
Is a session switched from the DB_GRP consumer group to another consumer group because it exceeded the prescribed switch time, then that session would execute even if the active session pool for the new consumer group was full.
第8题:
CPU_MTH
NEW_CPU_MTH

CPU usage
degree of parallelism
number of open cursors
number of sorts performed
idle time for blocking sessions

第10题:
The Resource Manager plan does not affect the user.
There must be a plan directive in any of the plans of the group to control the resources.
The members of the group DEFAULT_CONSUMER_GROUP always have resource restrictions.
The members of DEFAULT_CONSUMER_GROUP are restrained from accessing the system tables.
The members of this group can change their group without the database administrator’s intervention.
第11题:
Maximum Undo per consumer group
Maximum Idle time
Parallel server limit
CPU
Exadata I/O
Local file system I/O
第12题:
The batch operation started by the user, SCOTT, terminates with an error.
The batch operation started by the user, SCOTT, hangs and you are required to increase the undo pool resource plan directive.
The batch operation started by the user, SCOTT, runs uninterrupted because the database uses the SYSTEM tablespace for the undo operation.
The user, BLAKE, cannot start a transaction that uses any DML operations until you increase the value of the undo pool resource plan directive.
The user BLAKE can start a transaction that uses any DML operations after the batch operation started by the user, SCOTT, terminates with an error.
第13题:
You are using the Database Resource Manager to manage database resources. You created a resource plan directive for the MANAGERS resource consumer group under the SALES_PLAN by using the following statement: SQL>EXEC DBMS_RESOURCE_MANAGER.CREATE_PLAN_DIRECTIVE (PLAN => ’SALES_PLAN’, GROUP_OR_SUBPLAN => ’MANAGERS’, CPU_P1 => 100, CPU_P2 =>0, SWITCH_GROUP => ’CLERKS’, SWITCH_TIME_IN_CALL => 600); A user, SCOTT, who is assigned to the MANAGERS group, starts a database session and executes a query on the database. What is the outcome if the query takes approximately 15 minutes to complete?()
第14题:
You execute the following block of code: SQL>BEGIN DBMS_RESOURCE_MANAGER.CREATE_SIMPLE_PLAN ( SIMPLE_PLAN => ’DEPARTMENTS’, CONSUMER_GROUP1 => ’PAYROLLL’, GROUP1_CPU => 50, CONSUMER_GROUP2 => ’SALES’, GROUP2_CPU => 25, CONSUMER_GROUP3 => ’MARKETING’, GROUP3_CPU => 25); END; SQL>/ What is a prerequisite for using the simple resource plan created by executing the above code?()
第15题:
You updated the resource plan directive for the resource consumer group, DSS_USERS. The resource plan directive is assigned to the DSS_PLAN by using the following statement: SQL>EXEC DBMS_RESOURCE_MANAGER.UPDATE_PLAN_DIRECTIVE (PLAN => ’DSS_PLAN’, GROUP_OR_SUBPLAN => ’DSS_USERS’, NEW_CPU_P1 => 80, NEW_SWITCH_GROUP => ’CANCEL_SQL’, NEW_SWITCH_ESTIMATE => TRUE, NEW_SWITCH_TIME => 600); A user connects to the database and starts an operation. What is the outcome if Oracle estimates that the execution time for this operation will exceed 600 seconds?()
第16题:
Which statement is true while creating subplans using Resource Manager?()
第17题:
Which two files in the database can be configured for automatic backups by using the autobackup feature inRecovery Manager (RMAN)()
第18题:
The parallel degree limit for DB_GRP will be the minimum of all the incoming values.
The parallel degree limit for DB_GRP will be the maximum of all the incoming values.
The maximum estimated execution time for DB_GRP would be the most nonrestrictive of all incoming values.
If a session switched from the DB_GRP consumer group to another consumer group because it exceeded the prescribed switch time, then that session would not execute if the active session pool for the new consumer group was full.
If a session switched from the DB_GRP consumer group to another consumer group because it exceeded the prescribed switch time, then that session would execute even if the active session pool for the new consumer group was full.

第22题:
The subplan must belong to the consumer group, SYS_GROUP.
The total CPU usage at any given level must be less than 100%.
The subplans can be used to restrict the degree of parallelism for a user.
You can use a resource plan instead of a consumer group to implement a priority ranking within the plan.

第24题:
If no PDB plan is enabled for a pluggable database, then all sessions for that PDB are treated to an equal degree of the resource share of that pdb.
In a PDB plan, subplans may be used with up to eight consumer groups.
If a PDB plan is enabled for a pluggable database, then resources are allocated to consumer groups across all PDBs in the cdb.
If no PDB plan is enabled for a pluggable database, then the PDB share in the CDB plan is dynamically calculated.
If a PDB plan is enabled for a pluggable database, then resources are allocated to consumer groups based on the shares provided to the PDB in the CDB plan and the shares provided to the consumer groups in the PDB plan.
