能介绍一下PSPO,DBWO,RECO这几个进程吗?
PMON started with pid=2, OS id=4107
PSP0 started with pid=3, OS id=4109
MMAN started with pid=4, OS id=4111
DBW0 started with pid=5, OS id=4113
LGWR started with pid=6, OS id=4115
CKPT started with pid=7, OS id=4117
SMON started with pid=8, OS id=4119
RECO started with pid=9, OS id=4121
MMON started with pid=10, OS id=4123
MMNL started with pid=11, OS id=4125
查看了一些alert日志,发现里面有些进程不知道是什么东西,又人能够解释一下吗?
[解决办法]
PMON:监视用户连接状态
CKPT:用户整合控制文件和数据文件,
SMON:系统监视器,监视整个RDBMS
LGWR:在SGA中重做日志文件,重做日志缓冲区的内容写入
