介绍一款非常好用的10046分析工具--trca(Trace Analyzer)，以前分析10046跟踪文件的时候都是使用tkprof 工具，但是trca 比tkprof要简单的多而且分析的结果更全面：
可以从ML的文章：Trace Analyzer TRCANLZR - Interpreting Raw SQL Traces with Binds and/or Waits generated by EVENT 10046 [ID 224270.1] 来下载此工具！
trca.zip 主要包括一下文件
install：
TRCACREA.sql - creates all objects needed by Trace Analyzer by calling other scripts below.
TRCADROP.sql - drops the schema objects.
TRCAPKGB.sql - creates the package body.
TRCAPKGS.sql - creates the package header (specification).
TRCAREPO.sql - creates the staging repository.
TRCADIRA.sql - creates the directory object pointing to the place where the trace files exist (only if placing traces on a directory other than user_dump_dest).
TRCAGRNT.sql - grants privileges needed to use Trace Analyzer
TRCAREVK.sql - revokes privileges granted by TRCAGRNT.
TRCAPURG.sql - purges old SQL traces from the repository.
TRCATRNC.sql - truncates the staging repository.
TRCANLZR.sql - main Trace ANalyzer script. that generates the report.
TRCACRSR.sql - generates report for one cursor.
TRCAEXEC.sql - generates report for one cursor execution.
run：
trcanlzr.sql 用来分析10046产生的跟踪文件的 用法：
trcanlzr.sql controlfile |跟踪文件名
下面介绍一下trca的安装和使用
进入/trca/install 目录，以sys 用户登录数据库：
sys@RAC> @tacreate.sql
Uninstalling TRCA, please wait
TADOBJ completed.
sys@RAC>
sys@RAC> WHENEVER SQLERROR EXIT SQL.SQLCODE;
sys@RAC> REM If this DROP USER command fails that means a session is connected with this user.
sys@RAC> DROP USER trcanlzr CASCADE;
sys@RAC> WHENEVER SQLERROR CONTINUE;
sys@RAC>
sys@RAC> SET ECHO OFF;
TADUSR completed.
TADROP completed.
Specify optional Connect Identifier (as per Oracle Net)
Include "@" symbol, ie. @PROD
If not applicable, enter nothing and hit the "Enter" key
Optional Connect Identifier (ie: @PROD): @rac
Define the TRCANLZR user password (hidden and case sensitive).
Specify TRCANLZR password: --输入用户TRCANLZR的密码
Re-enter password:
Set up TRCANLZR temporary and default tablespaces
Below are the list of online tablespaces in this database.
Decide which tablespace you wish to create the TRCANLZR tables
and indexes. This will also be the TRCANLZR user default tablespace.
Specifying the SYSTEM tablespace will result in the installation
FAILING, as using SYSTEM for tools data is not supported.
Wait...
Above is the list of online tablespaces in this database.
Decide which tablespace you wish to create the TRCANLZR tables

Specifying the SYSTEM tablespace will result in the installation
FAILING, as using SYSTEM for tools data is not supported.
Tablespace name is case sensitive.
Default tablespace [UNKNOWN]: EXAMPLE --（必须大写，小写会创建失败）
DEFAULT_TABLESPACE
------------------------------
EXAMPLE
Choose the TRCANLZR user temporary tablespace.
Specifying the SYSTEM tablespace will result in the installation
FAILING, as using SYSTEM for the temporary tablespace is not recommended.
Wait...
TABLESPACE_NAME
------------------------------
TEMP
Tablespace name is case sensitive.
Temporary tablespace [UNKNOWN]: TEMP
TEMPORARY_TABLESPACE
------------------------------
TEMP
Type of TRCA repository
Create TRCA repoitory as Temporary or Permanent objects?
Enter T for Temporary or P for Permanent.
T is recommended and default value.
Type of TRCA repository [T]: T
