Oracle Trace File Analyzer 介绍及简单使用

一、什么是Oracle Trace File Analyzer
Oracle Autonomous Health Framework(AHF) 包含 Oracle ORAchk, Oracle EXAchk, and Oracle Trace File Analyzer(TFA). AHF工具包包含了Oracle常用的多种诊断工具，如 ORAchk, Oracle EXAchk, and Oracle Trace File Analyzer(TFA)等，用于Oracle健康检查等用途。

AHF的下载地址:
Autonomous Health Framework (AHF) - Including TFA and ORAchk/EXAchk (Doc ID 2550798.1)

其中Oracle跟踪文件分析器（Oracle Trace File Analyzer）以下简称tfa，是Oracle提供的一个重要的数据库诊断工具。tfa可以收集诊断数据和诊断信息，监视日志中是否存在可能影响您服务的重大问题。tfa可以标识日志文件中的相关信息，将日志文件修整为仅解决问题所需的部分，还可以跨集群节点收集数据，并将所有内容整合到一个位置。

为获得AHF工具的完整功能，建议以root用户安装；如果非root用户安装，其功能会减少。如果已安装 AHF，则重新安装会在现有位置进行升级。

二、在Linux以守护程序模式在root用户下安装
要获得Oracle Trace File Analyzer的全部功能，需要在root用户下安装tfa。tfa维护访问控制列表（ACL），以确定允许哪些用户访问。默认情况下，GRID_HOME所有者和ORACLE_HOME所有者可以访问各自的诊断信息。如果已经安装了Oracle tfa，则重新安装将升级到现有位置；如果尚未安装Oracle tfa，则推荐位置为/opt/oracle.tfa。

在root用户下执行：
2.1. 下载最新版AHF
2.1.1 使用SSO登陆Oracle Support网站
https://support.oracle.com
2.1.2检索文档ID 2550798.1，下载最新版AHF。
Autonomous Health Framework (AHF)-Including TFA and ORAchk/EXAchk (Document 2550798.1)

安装AHF
2.2 将压缩包上传到RAC数据库服务器其中的一台数据库服务器并解压。
Unzip AHF-LINUX_22.2.4.zip

2.2 在解压后的目录中执行AHF的安装命令。

[root@dkf19c01 soft]# unzip AHF-LINUX_v22.3.2.zip 
Archive:  AHF-LINUX_v22.3.2.zipinflating: README.txt              inflating: ahf_setup               extracting: ahf_setup.dat           inflating: oracle-tfa.pub    

具体的安装命令如下：

# ./ahf_setup -ahf_loc /opt -data_dir <ORACLE_BASE of Grid owner>
# ./ahf_setup -ahf_loc /opt -data_dir /u01/app/grid

安装过程如下：

三、 执行TFA进行巡检：

Run a Oracle Trace File Analyzer (TFA) Collection
With the installation complete we can use the tfactl command to perform a number of collections, including TFA Service Request Data Collections (SRDC). There are a large number of SRDC collection types, with each gathering different information, as described here.Here are a few examples.cd /opt/oracle.ahf/tfa/bin/# Gather diagnostic information about TFA itself.
./tfactl diagnosetfa -local# Gather information about errors. You are prompted to select a specific incident.
./tfactl diagcollect -srdc ORA-00600
./tfactl diagcollect -srdc ORA-07445# Collect data for all components for a specific time period.
./tfactl diagcollect -from "2022-06-16 13:00:00" -to "2022-06-16 13:00:00"# Collect data for all components for the last 12 hours.
./tfactl diagcollect
Each TFA collection produces a single zip file that can be uploaded to My Oracle Support (MOS), as described below.
