公司有一项目使用oracle10g作为数据库。在完成安装后公司开发人员要我设置一些参数，我通过10g的em web页设置了session=1000,session_max_open_files=100,PGA=256M.重启后就发现数据库不能正常运行。在系统服务里面可以正常关闭打开oracle的所有服务。但是进入10g em web页显示数据库当前为装载或者未装载状态，要我启动或者恢复设置。但是无论我如果启动或者恢复，都不能使oracle正常运行。用sqlplus不能登陆。请教各位这是什么原因导致的？是因为参数设置出错的问题吗？因为在设置这3个参数前数据库一直都是运作正常的。

你那个PGA直接设置为256是行不通的吧？
再说你没理解pga是什么意思吧 他不可以直接设置的吧？？？？
pga=java_pool_size+large_pool_size+shared_pool_size+db_cache_size
PGA只是用户数据加后台进程，和排序用到的

->shared_pool_size = 83886080
此外，在DEDICATED模式下，你只加大sessions数，不增加processes数应该是没意义的。
10g里这个值不是自动调整的吗?
