Basic Memory Structures The basic memory structures associated with Oracle Database include: System global area (SGA) The SGA is a group of shared memory structures, known as SGA components, that contain data and control information for one Oracle Da…
Oracle Database creates and uses memory structures for various purposes. For example, memory stores program code being run, data that is shared among users, and private data areas for each connected user. Two basic memory structures are associated wi…
http://luisbg.blogalia.com/historias/74062 Thanks to Vijay D'Silva's brilliant answer in cstheory.stackexchange.com I have been reading some of the famous data structures and algorithms used in the Linux Kernel. And so can you. Links based on linux 2…

1.操作 (oracle使用内存约等于 SGA+PGA,所以可以减少SGA与PGA解决你的问题,生产库慎用)alter system set sga_max_size=100m scope=spfile; --减少SGA大小,静态参数,重启后生效alter system set sga_target=80m scope=both; --动态参数:oracle推荐:启动时修改此参数,不要动态设置此参数alter system set pga_aggregate_target=40m…

Understanding Memory Management Memory management is the process of allocating new objects and removing unused objects to make space for those new object allocations. This section presents some basic memory management concepts and explains the basics…
It’s coming up on a year since we published our last memory review; possibly the longest hiatus this section of the site has ever seen. To be honest, the reason we’ve refrained from posting much of anything is because things haven’t changed all that…
BACKGROUND Memory allocation systems assign blocks of memory on request. A memory allocation system employs an allocator to receive relatively large blocks of memory from an operating system and allocate that memory to satisfy memory requests. Upon r…
