通过这里可以看出,系统的data buffe和pga都有内存不足的报错.
解决问题
问题的原因是由于内存分配不多,导致sga组件被消耗完,现在数据库不能正常关闭,修改了相关的内存参数的配置[避免该bug采用asmm内存管理]也无法生效,现在需要做的任务是重启数据库.导致数据库不能被关闭的原因是因为data buffer中的脏数据不能写入新数据.查询MOS发现是Bug 7702085.正常关闭库解决办法手工刷sga组件,然后升级数据库到11.2.0.1 (Base Release)/11.1.0.7.3 (Patch Set Update)/11.1.0.7 Patch 25 on Windows Platforms
