PGA和sql work area 相关视图

原创 Linux操作系统 作者:leecheery 时间:2009-05-12 10:41:26 0 删除 编辑
There are fixed views and columns that provide PGA memory use statistics. Most of
these statistics are enabled when PGA_AGGREGATE_TARGET is set.
 Statistics on allocation and use of work area memory can be viewed in the
following dynamic performance views:
V$SYSSTAT
V$SESSTAT
V$PGASTAT
V$SQL_WORKAREA
V$SQL_WORKAREA_ACTIVE
 The following three columns in the V$PROCESS view report the PGA memory
allocated and used by an Oracle process:
PGA_USED_MEM
PGA_ALLOCATED_MEM
PGA_MAX_MEM
