Action plan/Solution
=========================
1. Trace file generated with:
alter system set events '10235 trace name context forever, level 65536';
alter system set events '4031 trace name errorstack level 3;name heapdump level 536870914';
2. After trace generation, the events can be disabled with:
alter system set events '4031 trace name errorstack off;name heapdump off';
alter system set events '10235 trace name context off';
=========================
或者采用下面的方式:
conn / as sysdba
oradebug setmypid
oradebug unlimit
oradebug dump heapdump 536870914
oradebug tracefile_name
oradebug close_trace
-----------方法1----------------
挂起时在一个实例上用sysdba 执行：
1 执行挂起分析
sqlplus -prelim / as sysdba
oradebug setmypid
oradebug unlimit
oradebug -g all hanganalyze 3
等30秒
oradebug -g all hanganalyze 3
oradebug tracefile_name
exit
2 打开另一个会话，抓取状态
sqlplus -prelim / as sysdba
oradebug setmypid
oradebug unlimit
oradebug -g all dump systemstate 10
等30秒
oradebug -g all dump systemstate 10
oradebug tracefile_name
exit
-----------方法2----------
抓取系统状态(10g)
sqlplus -prelim / as sysdba
oradebug setmypid
oradebug unlimit
oradebug -g all dump systemstate 266
等30秒
oradebug -g all dump systemstate 266
exit
如果产生的diag文件太大或挂起
在各实例上执行
sqlplus -prelim / as sysdba
oradebug setmypid
oradebug unlimit
oradebug hanganalyze 3
等30秒
oradebug hanganalyze 3
oradebug dump systemstate 258
oradebug tracefile_name
exit
11g 及以上
oradebug setospid
oradebug unlimit
oradebug -g all hanganalyze 3
等30秒
oradebug -g all hanganalyze 3
oradebug -g all dump systemstate 258
exit
