一.TRCA 说明
分析10046的trace 文件，之前介绍过一个工具，tkprof，但是tkprof的功能有限。 相比之下，TRCA工具则能提供更加详细的报告。
关于tkprof 工具说明，参考之前的Blog：
http://blog.csdn.net/tianlesoftware/article/details/5632003
http://blog.csdn.net/tianlesoftware/article/details/5857023
Trace Analyzer,also known as TRCANLZR or TRCA, is a toolprovided by Oracle Server Technologies Center of Expertise - ST CoE. TRCAinputs one or several SQL trace(s) generated by Event 10046 and outputs adiagnostics report in two formats (html and text). These reports are commonly usedto diagnose processes performing poorly.
--Trace Analyzer，也称TRCANLZR 或者 TRCA，其由STCoE 提供。 TRCA 输入一个或者多个10046 的trace 文件，然后生成诊断报告，报告有2种格式：html和text。
TRCA identifiesexpensive SQL out of the provided trace(s), then it connects to the databaseand collects their explain plans, Cost-based Optimizer CBO statistics,metadata, configuration parameters, and similar elements that influence theperformance of the process being analyzed.
--TRCA 可以通过trace 分析消耗资源多的SQL时，会连接数据库，收集其执行计划，CBO 的统计信息，metadata，配置参数。 同样的道理，影响性能的进程也会被分析。
For best outputresults TRCA must be installed and used in the same system and database wherethe trace is generated. Understanding that installing TRCA in a production systemis not always possible, TRCA is capable of analyzing a trace using a differentsystem. Refer to the included instructions for details.
--为了达到最好的分析结果，TRCA 必须安装在产生trace 文件相同的系统和数据库上，不过一般生产环境不允许安装TRCA。 TRCA 可以分析跨系统分析trace 文件。
TRCA 工具可以从MOS上下载：
Trace Analyzer TRCANLZR - Interpreting RawSQL Traces with Binds and/or Waits generated by EVENT 10046 [ID 224270.1]
也可以从我的CSDN 下载：
http://download.csdn.net/detail/tianlesoftware/4053543
二.使用示例
2.1 安装TRCA
TRCA installsunder its own schema TRCANLZR. It does not install any objects into theapplication schema(s). You can install this version of TRCA in Oracle databases9.2, 10.1, 10.2, 11.1, 11.2 and higher, on UNIX, Linux or Windows platforms.
--TRCA 会安装到自己的用户：TRCANLZR，不会安装对象到其他用户。
安装方法：
--先解压缩trca，然后使用sys用户运行tacreate.sql

小结：
1.我这里的测试环境：
Source ： linux + Oracle10gR2
Target ： win7 + Oracle 11gR2
2. 不同系统与同系统的区别在于，当系统不同时，需要先使用trca 脚本，把Source 库的data dictionary 导出在导入到Target 系统上，然后使用trcanlzr用户来进行操作。
如果是同系统，那么直接使用生成trace 的用户来连接，因为在分析时，其要收集相关的信息。
2.3.4 在Target系统上分析Source系统上的多个trace 文件
这里的流程和前面的就差不多了。
（1）在Source 库用SYS用户执行trca/dict/trcadictexp.sql脚本，导出TRCA_DICT.ZIP。
# sqlplus / as sysdba
SQL> START trcadictexp.sql
（2）将生成的TRCA_DICT.ZIP 文件拷贝到TARGET系统的TRCA$STAGE目录下，通常是USER_DUMP_DEST。然后解压缩，将文件直接放在TRCA$STAGE目录下。
（3）将要分析的trace 文件都拷贝到Target 系统的TRCA$INPUT1目录下。
（4）创建控制文件，control_file.txt，将要分析的trace 文件名写入control_file.txt,每行一个文件名，不包含路径，然后将控制文件放到TRCA$INPUT1下。
（5）在Target系统上使用TRCANLZR用户连接sqlplus，然后执行trca/dict/trcadictimp.sql导入Source 库的数据字典，在执行trca/run/trcanlzr.sql 脚本分析trace 文件。
三.常见问题
3.1 What is new in this TRCA release?
A summary ofrecent TRCA changes can be found in file trca/doc/trca_changes.html.
3.2 Can I change the TRCA staging directory?
Yes,use trca/utl/tacdirs.sql passing the full directory path. This pathcannot contain the "?" or "*" symbols and it is casesensitive in most systems. This directory must exist in the serverand ORACLE must have read/write access to it.
3.3 Can I change the TRCAinput directories?
Yes, but this isnot recommended. You can use trca/utl/tacdiri1.sql or trca/utl/tacdiri2.sql passing the full directory path. This pathcannot contain the "?" or "*" symbols and it is casesensitive in most systems. This directory must exist in the serverandORACLE must have read access to it.
3.4 How can I expedite"Taking a snapshot of some Data Dictionary objects"?
A snapshot ofsome Data Dictionary objects takes between a couple of minutes and up toseveral hours, depending on the size of the data dictionary. This is the laststep of the installation. If killed, it will be automatically executed when thetool is first used.
To expedite thesnapshot time, and with some loss of functionality, you can disable the snaphotof extents by executing these commands connecting as TRCANLZR:
SET SERVEROUT ON;
EXEC trca$g.set_param('capture_extents', 'N');
EXEC trca$t.refresh_trca$_dict_from_this;
If still"Taking a snapshot of some Data Dictionary objects" takes longer thanseveral hours, it can be disabled altogether with significant loss of functionality,by executing these commands connecting as TRCANLZR:
SET SERVEROUT ON;
EXEC trca$g.set_param('refresh_dict_repository', 'N');
EXEC trca$t.refresh_trca$_dict_from_this;
