Oracle TFA日志收集工具的安装与使用
2024-03-31 01:43:09
TFA日志收集工具:
一.介绍:
TFA全称：Trace File Analyzer，日志分析工具。
TFA会监视的日志，以发现可能影响服务的重大问题，在检测到任何潜在问题时也会自动收集相关的诊断信息。
TFA可以识别日志文件中的相关信息，将日志文件修剪为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地方。工作方式:
1.DBA发出diagcollect命令，启动TFA日志收集进程。
2.本地TFA发送收集请求至其他节点的TFA，在其他节点上开始日志收集工作。
3.本地TFA也同时开始进行日志收集工作。
4.所有涉及节点的TFA日志都归档至发起diagcollect命令的"master"节点。
5.DBA提取已归档的TFA日志信息，进行分析或提交SR进行处理
二.安装,启动与关闭:
需配置root的环境变量，否则会报ERROR: ORACLE_HOME is not set
[root@rac19cn1 ~]# more .bash_profile
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then. ~/.bashrc
fi
# User specific environment and startup programs
PATH=$PATH:$HOME/bin
export PATH
export ORACLE_HOME=/oracle/app/product/193000/db_1[root@rac19cn1~]#cd /oracle/app/product/193000/db_1/suptools/tfa/release/tfa_home/install/
[root@rac19cn1 install]# ls

启动关闭:
启动:
[root@rac19cn1 bin]# ./tfactl

三.日志收集:
仅收集数据库相关日志
tfactl> diagcollect -database ora19c
By default TFA will collect diagnostics for the last 12 hours. This can result in large collections
For more targeted collections enter the time of the incident, otherwise hit <RETURN> to collect for the last 12 hours
[YYYY-MM-DD HH24:MI:SS,<RETURN>=Collect for last 12 hours] :

四.日志分析:
Oracle提供了analyze命令来帮助我们分析数据库当前的trace文件
常用:
tfactl> analyze -search "ORA-" -since 1d INFO: analyzing all (Alert and Unix System Logs) logs for the last 1440 minutes... Please wait...
INFO: analyzing host: rac19cn1Report title: Analysis of Alert,System LogsReport date range: last ~1 day(s)Report (default) time zone: CST - China Standard TimeAnalysis started at: 06-Nov-2020 09:28:08 AM CSTElapsed analysis time: 15 second(s).Configuration file: /oracle/grid/crs_1/tfa/rac19cn1/tfa_home/ext/tnt/conf/tnt.propConfiguration group: allParameter: ORA-Total message count: 24,938, from 25-Aug-2020 06:22:19 PM CST to 06-Nov-2020 09:20:01 AM CST

以上os、db、asm、crs等所有日志都分析.仅分析最近两天数据库实例的日志
tfactl> analyze -comp db -since 2d
-comp参数可以指定级别为os、db、asm、acfs、crs、all，默认的话是all，表示所有的都收集。
五:其他操作:
查看当前哪些用户可以使用tfactl
tfactl> access lsusers
.---------------------------------.
