There is a call center application that repetitively sends tactical queries to Vantage These queries use a few small tables that are joined on the primary index column.
The following maps are defined in the system:
* TD_GlobalMap
* TD_Map1
* TD_DataDictionaryMap
* TD_1AmpSparseMap_1Node
What can be done to optimize these queries?
- A . Assign these tables to TD_1AmpSparseMap_1Node using different colocation names for each table.
- B . Assign these tables to TD_1AmpSparseMap_1Node using the same colocation name for every table
- C . Assign these tables to TD_Map1 using the same colocation name for every table.
- D . Assign these tables to TD_Map1 using different colocation names for each table.
Which workload management technique should the Administrator use to reject all QueryGrid
queries during a pre-defined critical batch state?
- A . An exception that includes the following Foreign Servers:
TD_SYSFNLIB.QGInitiatorExport
TD_SYSFNLIB.QGInitiatorlmport
TD_SYSFNLIB.QGRemoteExport
TD_SYSFNLIB.QGRemotelmport - B . A filter that includes the following functions:
TD_SYSFNLIB.QGInitiatorExport
TD_SYSFNLIB.QGInitiatorlmport
TD_SYSFNLIB.QGRemoteExport
TD_SYSFNLIB.QGRemotelmport - C . An exception that excludes the following Foreign Servers:
TD_SYSFNLIB.QGInitiatorExport
TD_SYSFNLIB.QGInitiatorlmport
TD_SYSFNLIB.QGRemoteExport
TD_SYSFNLIB.QGRemotelmport - D . A filter that excludes the following functions:
TD_SYSFNLIB.QGInitiatorExport
TD_SYSFNLIB.QGInitiatorlmport
TD_SYSFNLIB.QGRemoteExport
TD_SYSFNLIB.QGRemotelmport
A customer is complaining that the creation of a large table in the lab environment is getting stuck in the merge step. The customer is using the following command to create the table: CREATE TABLE … AS (SELECT * …) WITH DATA
Which recommendation will help the merge step?
- A . A column that provides good distribution should be specified as PRIMARY INDEX.
- B . The MERGEBLOCKRATIO should be specified for the table to improve the data block merge operation.
- C . The table should be created with "CREATE TABLE … AS (SELECT *…) WITH NO DATA", and afterwards, "INSERT … SELECT *" should be used to fill the table.
- D . Users of the lab may have lower priority than other workloads, so the creation of the table should be moved to off-peak hours.
Which benefit is achieved by creating profiles?
- A . Reducing the growth of the DBC.AccessRights table
- B . Managing user privileges on database objects
- C . Assigning permanent space for groups of users with similar needs
- D . Defining spool space for groups of users with similar needs
What is a use case for Data Mover?
- A . Archiving data to a Hadoop system
- B . Copying data between Vantage systems for active-active replication
- C . Replicating data to a disaster recovery system
- D . Copying data between Hadoop systems
An Administrator manages a Vantage system that is continually updated. The system is critical to the business and must be available as much as possible. The Administrator decides to use a backup strategy that will allow changes to tables while a backup is in progress.
Which backup strategy should be used?
- A . Offline
- B . Skip statistics
- C . Online
- D . Dictionary Only
A client is having many problems with a poorly written SQL. They have product joins running against large tables, and this is causing severe performance issues. The Administrator needs to help the client avoid the harm to the system that is being caused by running these queries.
Which action should be taken by the Administrator to assist this client?
- A . Use the Query Spotlight Viewpoint portlet to deprioritize the queries.
- B . Use the Flex Throttle option.
- C . Use a TASM system filter.
- D . Use the Query Log Viewpoint portlet to identity and abort the harmful queries.
The Administrator has dropped a profile which was associated with a group of users.
What will happen when one of the users from the group logs on to the database?
- A . The default profile setting for the user will be reset to NULL.
- B . Password attributes defined at the system level in DBCSecurityDefaultsV will apply
- C . The system will show a warning message.
- D . SPOOL and DEFAULT DATABASE specifications for the dropped profile will still apply to the user.
An Administrator has been asked to improve the response time of the workloads in the tactical tier. Workloads are in all tiers of TASM. They are at CPU and I/O capacity, and they have AWT reserved for tactical. The Administrator begins by analyzing the data and the workload prioritization.
Which action should the Administrator take?
- A . Increase the relative weight of the tactical tier.
- B . Disable the expedite option of the workloads in the SLG Tier level 1.
- C . Increase the number of AWTs.
- D . Adjust the limits of awt concurrency in the tactical tier using DBS control.
At a large car manufacturer, huge volumes of diagnostic data for cars are collected in the following table:
The master data for each car is stored in the following table:
Many reports require data from both tables by joining via column VehicleId.
A very frequently performed query on the system returns the number of events by FaultCode and ModelType. This query consumes many CPU and I/O resources each day.
Which action should the Administrator take to improve the runtime and resource consumption for this query?
- A . Use an aggregate join index with columns FaultCode, ModelType, as well as an appropriate aggregate function.
- B . Use a sparse join index with columns FaultCode and ModelType, as well as an appropriate filter function.
- C . Use a NUSI on VehicleEvent.FaultCode and a NUSI on Vehicle.ModelType
- D . Use a single table join index on VehicleEvent hashed by FaultCode and another single table join index on Vehicle hashed by ModelType.
