dual 缺少同义词故障解决

发表于 2012 年 10 月 30 日 由 惜分飞

在最近的一个客户案例中,因为缺少dual同义词,导致ddl语句无法执行。这里_system_trig_enabled参数和upgrade模式两种来解决该问题,整体上来说_system_trig_enabled不用重启数据库终止业务,更加人性化.
缺少dual同义词后果

原因分析并解决

New controlfile enqueue hold time tracking statistics have been added in 11.2 to 
aid diagnosis of controlfile transaction related performance related issues.

To disable the trace set _controlfile_enqueue_holding_time_tracking_size to 0:

- spfile
alter system set "_controlfile_enqueue_holding_time_tracking_size"=0 scope=spfile;

- pfile
_controlfile_enqueue_holding_time_tracking_size=0

A database restart is required.

补充MOS说明[791417.1]

New controlfile enqueue hold time tracking statistics have been added in 11.2 to aid 
diagnosis of controlfile transaction related performance related issues:

Control File Enqueue AWR Statistics:
max cf enq hold time - The maximum amount of time in milliseconds a client has held the control file enqueue.
total cf enq hold time - The total amount of time in milliseconds all clients have held the control file enqueue.
total number of cf enq holders - The total number of times clients have held the control file enqueue.

Periodically, the CKPT process dumps statistics for the top N control file enqueue holders. 
N defaults to 10, but can be modified with the static hidden 
parameter: _controlfile_enqueue_holding_time_tracking_size.The dump looks like the following:

Preface: "Control file enqueue hold time tracking dump at time: [relative time]".
a. Time the client has held the control file enqueue.
b. Type of client's control file enqueue transaction - rw or ro.
c. File name where the client obtained control file enqueue.
d. Line number where the client obtained control file enqueue.
e. Number of times the client has held the control file enqueue since it became a member of the top N.
f. Total time the client has held the control file in all those times from [e].
g. Relative time the client obtained the control file enqueue from [a].
