第6题:
When tuning Automatic PGA Memory Management, which of the following views will provide the information specified?()
第7题:
利率代码表的交易代码是()
第8题:
Set MEMORY_TARGET to zero
Set the STATISTICS_LEVEL parameter to BASIC
Set the WORKAREA_SIZE_POLICY parameter to MANUAL
Set the PGA_AGGREGATE_TARGET parameter to nonzero value
第9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10题:
All the *_AREA_SIZE parameters are ignored.
The Automatic PGA Memory Management feature cannot be disabled.
The total Program Global Area (PGA) memory cannot be manually increased above 800M.
The total memory for the PGA can automatically exceed 800M using the Automatic PGA Memory Management feature.
第11题:
The V$PGA_TARGET_ADVICE view shows the predicted cache hit-ratio improvement if you increase PGA_AGGREGATE_TARGET
The V$PGA_TARGET_ADVICE view shows how the V$SQL_WORKAREA histogram will change if you change the value of PGA_AGGREGATE_TARGET
The V$PGA_TARGET_ADVICE_HISTOGRAM view shows how the V$SQL_WORKAREA_HISTOGRAM will change if you switch between Manual and Automatic PGA Memory Management
The V$PGA_TARGET_ADVICE view shows how performance will improve for the different work areas if you switch from Manual to Automatic PGA Memory Management
