第4题:
In Oracle 11g,by default which one of the following conditions implicitly enables Automatic PGA Memory Management?()
第5题:
By setting the value of MEMORY_TARGET to zero and setting the value of SGA_TARGET to a nonzero value, you will enable which of the following memory-management options?()
第6题:
Setting a nonzero value for SGA_TARGET
Configuring Automatic Shared Memory Management
Configuring Automatic Memory Management
Setting a nonzero value for SGA_MAX_SIZE and PGA_AGGREGATE_TARGET
None of the above
第7题:
Automatic memory management is disabled because PGA_AGGREGATE_TARGET and SGA_TARGET are not set
The instance is started but the database will not be opened until PGA_AGGREGATE_TARGET and SGA_TARGET are set
The database is opened but users cannot perform transactions until PGA_AGGREGATE_TARGET and SGA_TARGET are set
Automatic memory management is enabled and, as per policy, 60% of the memory for System Global Area (SGA) and 40% of the memory for Program Global Area (PGA) will be distributed at startup
第8题:
modify the HASH_AREA_SIZE initialization parameter
modify the PGA_AGGREGATE_TARGET initialization parameter
modify the WORK_AREASIZE_POLICY initialization parameter
increase the value of the SGA_TARGET initialization parameter
increase the value of the SGA_MAX_SIZE initialization parameter
increase the value of the SORT_AREA_SIZE initialization parameter
第9题:
Automatic PGA Memory Management
Automatic SGA Memory Management
Automatic Shared Memory Management
Automatic Memory Management
Manual SGA Memory Management
None of the above
第10题:
The database instance starts, and Oracle sets the default value of SGA_TARGET to the same value as SGA_MAX_SIZE
The database instance starts, and Oracle automatically tunes memory and allocates 60 percent to the SGA and 40 percent to the PGA
The database instance starts, but Automatic Memory Management is disabled
The database instance will not start because you did not specify the PGA_AGGREGATE_TARGET or SGA_TARGET parameter
第11题:
PGA是SGA的一部分,SGA是共享的,但分配后的PGA是不共享的
PGA是客户机内存的一部分,而SGA是服务器内存的一部分
PGA和SGA都是服务器内存的一部分,前者是私有的,后者是共享的
PGA与SGA的总和等于服务器主机内存的总和
第12题:
Automatic PGA Memory Management
Automatic SGA Memory Management
Automatic Shared Memory Management
Automatic Memory Management
Manual SGA Memory Management
None of the above
第13题:
You specify a nonzero value for the MEMORY_TARGET initialization parameter, but do not set thePGA_AGGREGATE_TARGET or the SGA_TARGET parameters. You restart your database instance.Which statement about the result is true?()
第14题:
For Oracle 11g, Oracle strongly recommends that you configure your database to use which of the following memory-management features?()
第15题:
Which of the following Oracle features is enabled by setting a nonzero value for the MEMORY_TARGET initialization parameter?()
第16题:
Oracle Instance由哪两个部分组成?()
第17题:
The DBA has chosen to manage SGA and PGA memory separately in an OLTP database because of his unique knowledge of the application. Which of these are good starting points to use when configuring the maximum values for SGA and PGA,based on the amount of memory available on the system?()
第18题:
第19题:
It collects data from SGA and compares it with a preserved snapshot.
It collects data from SGA, analyzes it, and provides a report.
It collects data from SGA and compares it with the latest snapshot.
It collects data from both SGA and PGA, analyzes it, and provides a report
第20题:
modify the HASH_AREA_SIZE initialization parameter
modify the PGA_AGGREGATE_TARGET initialization parameter
modify the WORK_AREASIZE_POLICY initialization parameter
increase the value of the SGA_TARGET initialization parameter
increase the value of the SGA_MAX_SIZE initialization parameter
increase the value of the SORT_AREA_SIZE initialization parameter
第21题:
You cannot specify MEMORY_TARGET if you explicitly specify SGA_TARGET or PGA_AGGREGATE_ TARGET values that are greater than zero in your parameter file.
Oracle can reallocate memory between the SGA and PGA automatically as needed.
To use Automatic Memory Management, you must explicitly set both the MEMORY_TARGET and MEMORY_MAX_TARGET parameters in your parameter file.
You can set the MEMORY_TARGET parameter to a maximum value of the current SGA size plus the current PGA size.
第22题:
20% SGA 80% PGA
25% SGA 75% PGA
50% SGA 50% PGA
75% SGA 25% PGA
80% SGA 20% PGA
第23题:
