帮我看看参数怎样更改
最近总是发生日志过一段时间就满情况（一两个月，以前不是这样），又要增大日志。帮忙看看哪些参数需要修改，其他的需要优化的参数也可以提出来，谢谢服务器：RS6000操作系统：AIX

[ 本帖最后由 jasonamoy 于 2009-1-21 15:48 编辑 ] 你的 USER EXIT 及 Log Retain = NO
那就是使用 Circular Logging
满了也没关事啊...
都是 循环 使用 那个 xxx.log 日志满了之后,前台应用程序无法保存数据,虽然提示成功,实际没有保存;
若将日志文件清除,对数据库的使用有无影响
[ 本帖最后由 jasonamoy 于 2009-1-23 16:48 编辑 ] 看你的参数,日志应该是活动日志,不是归档模式,日志会自动清理的。
出现你说的情况，我认为可能性有两个：
1、单次事务需要写的日志，你所有日志都不够写，这个可能性几乎不存在。
2、就是你日志目录/home/ts/ts/NODE/ 空间不够
千万不要手动去删除数据库日志，否则数据库可能启动不了 如果日志目录 空间足够大，可试着调大单个日志文件的大小。 个数很多,单个太小
