Oracle推荐的使用systemstate事件的几种情况是：
-数据库hang住了
-数据库很慢
-进程正在hang
-数据库出现某些错误
-资源争用
1.命令
sqlplus -prelim / as sysdba
(1).单实例
SQL>oradebug setmypid
SQL>oradebug unlimit
SQL>oradebug dump systemstate 258
等1~2分钟
SQL>oradebug dump systemstate 258
等1~2分钟
SQL>oradebug dump systemstate 258
(2).RAC
SQL>oradebug setmypid
SQL>oradebug unlimit
SQL>oradebug -g all dump systemstate 258 <==-g all 表示针对所有实例生成dump
等1~2分钟
SQL>oradebug -g all dump systemstate 258
等1~2分钟
SQL>oradebug -g all dump systemstate 258
2.使用ass109.awk解析trace文件
$ awk -f /oracle/ORA10/10.2.0/ass109.awk ora10_ora_22855.trc
