Metric Descriptions


Metric	Description
PGA Aggregate Target	The value of the PGA Aggregate Target parameter in bytes. The pga_aggregate_target parameter, which was introduced in Oracle 11g, defines the total amount of memory available in Oracle for allocation to the PGA memory structure. If the value of this parameter is set correctly, all work areas executed by the system since start-up are processed exclusively in the PGA memory, requiring no extra passes. In such a case, the PGA hit percent’s value is 100%, and Oracle does not need to allocate extra memory to the PGA. However, when this value is set too small, the hit percent’s value decreases, and Oracle may need to perform one or more extra memory allocations.
PGA Hit Percent	The PGA cache hit ratio (as a percentage). When the value of this metric is 100%, it indicates that all work areas executed by the system processed the entire input data exclusively via the PGA memory, thereby making optimal use of this memory. Any lower value indicates that at least one work area required one or more extra passes over the input data.
PGA Overallocation Count	The number of extra PGA memory allocations that were carried out during the specified time range. Over-allocating PGA memory can happen if the value of the dynamic initialization parameter, PGA_AGGREGATE_TARGET, which is set to all server processes, is too small to allow executing all work area workload (operations) exclusively in the PGA memory. Such a scenario requires Oracle to allocate extra PGA memory. Ideally, the PGA cache hit ratio should be close to 100%, resulting in an extremely small number (close to zero) of PGA overallocations. High values of the PGA Overallocation Count metric indicate the need to increase the value of PGA_AGGREGATE_TARGET.
