Directly passe the arguments to the PL/SQL
procedure. Args are:
sql_id, session_id, session_serial,
sql_exec_start, sql_exec_id, inst_id,
instance_id_filter, parallel_filter,
report_level, type.
Examples:
- monitor xml shows XML report
- monitor show last monitored stmt
- monitor sql_id=>'8vz99cy9bydv8',
session_id=>105 will
show monitor info for sql_id
8vz99cy9bydv8 and session_id 105
Use simply ora monitor 8vz99cy9bydv8
to display monitoring information for
sql_id 8vz99cy9bydv8.
Syntax for parallel filters is:
<svr_set>[,]
<srv_num>)]
Use /*+ monitor */ to force monitoring.
- monitor_old [<sqlid>]
]]
Old version of SQL monitoring, use a
SQL query versus the report_sql_monitor()
package. Display monitoring info for the
LAST execution of the specified cursor.
Cursor response time needs to be at
least 5s for monitoring to start (use the
monitor hint to force monitoring). Without
any parameter, will display monitoring info
for the last cursor that was monitored
- ash_all will aggregate ash data over all
executions of the cursor (useful for short
queries that are executed many times).
If parallel:
- qc to see only data for qc
- slave_grp# to see only data for one
parallelizer
- slave_grp# + slave_set# to see only data
for one slave set of one parallelizer,
- slave_grp# + slave_set# + slave# to see
data only for the specified slave
- sql_task [progress | interrupt <task_name> | history <#execs> |
report <task_name> <section> <exec_name> ]
progress: progress monitoring for executing
sql tasks
interrupt: interrupt an executing sql task
history: print a history of last n executions
report: get a sql tune report
- sh Run a shell command. E.g.
ora repeat 5 10 sh 'ps -edf | grep DESC'
Memory: The detailed memory dumps need to have events set to work.
The events bellow can be added to the init.ora file
event="10277 trace name context forever, level 10" # mutable mem
event="10235 trace name context forever, level 4"# shared mem
NOTE
====
- Set environment variable ORA_USE_HASH to 1 to get SQL hash values
instead of SQL ids
- Set environment variable DBUSER to change default connect string which
is "/ as sysdba"
- Set environment variable ORA_TMP to the default temp directory (default
if /tmp when not set)

ora的功能非常强大,其实本质都是通过sql语句查询实现,可以通过数据库做10046来捕获相关sql.学习oracle,工具只是提高大家工作的效率,而不是刻意去追求工具本身
具体参考惜分飞blog：ora程序简单测试
这个工具不错！自己增加了一些，但是不知道又让我扔到那个角落去了！:'( 好强大. 工具不错，使用起来挺方便，不用记录那么多的SQL 好东西要支持！！！ 下载 看看 谢谢 飞总 分享 {:2_28:}发现 要权限 yrg5101 发表于 2014-3-16 16:39
发现 要权限
需要升级到注册会员就可以了，你现在还是新手上路，谢谢支持 一直有这个工具，但是还没有在生产上面使用过。 只能等升级到注册会员..
