oracletracefileanalyzer（tfa）使用方法（含bug解决）一。12c自带了一个很好用的日志分析工具，tfa可以帮您快速分析当前日志。迅速定位和分析日志，是dba很好的帮手。
一、安装
在安装12c的程序的最后一步执行root脚本的时候，会有如下提示
entries will be added to the /etc/oratab file as needed by
database configuration assistant when a database is created
finished running generic part of root script.
now product-specific root actions will be performed.
do you want to setup oracle trace file analyzer (tfa) now ? yes|[no] :
oracle trace file analyzer (tfa - user mode) is available at :
/u01/app/oracle/product/12.2.0/dbhome_1/suptools/tfa/release/tfa_home/bin/tfactl
or
oracle trace file analyzer (tfa - daemon mode) can be installed by running this script :
/u01/app/oracle/product/12.2.0/dbhome_1/suptools/tfa/release/tfa_home/install/roottfa.sh
如果选择no，那就不会安装该工具，默认是no，如果未在安装时选择安装该工具，也可以用，文中提示的两种方式启动tfa，一种是直接到
/u01/app/oracle/product/12.2.0/dbhome_1/suptools/tfa/release/tfa_home/bin/tfactl目录下执行命令操作，另一种方式是安装到
使用root执行该脚本，将可以直接使用tfa命令读取日志内容
/u01/app/oracle/product/12.2.0/dbhome_1/suptools/tfa/release/tfa_home/install/roottfa.sh，执行完毕会有如下提示
/u01/app/oracle/product/12.2.0/dbhome_1/suptools/tfa/release/tfa_home/install/roottfa.sh
installing oracle trace file analyzer (tfa).
log file: /u01/app/oracle/product/12.2.0/dbhome_1/install/root_12cr2.yudean.com_2017-03-14_15-53-55.log
finished installing oracle trace file analyzer (tfa)
二、使用
安装好tfa后设置好环境变量，我们看下tfa支持哪些命令，首先是tfactl 我们用help看下有哪些我们可以使用。
[oracle@12cr2 ~]$ . oraenv oracle_sid = [prod] ? prod1 the oracle base has been changed from /home/oracle to /u01/app/oracle [oracle@12cr2 ~]$ tfactl tfactl> help usage : /u01/app/oracle/tfa/bin/tfactl[options] commands:diagcollect|collection|analyze|ips|run|start|stop|print|directory|toolstatus for detailed help on each command use: /u01/app/oracle/tfa/bin/tfactl
-help
1、启动和关闭
命令tfactl start 和tfactl stop2、查看当前哪些用户可以使用tfactl
该命令一般使用tfa admin权限的用户，使用安装tfa的用户执行，这里是root用户
tfactl> access lsusers
.---------------------------------. | tfa users in 12cr2 | +-----------+-----------+---------+ | user name | user type | status | +-----------+-----------+---------+ | oracle | user | allowed | '-----------+-----------+---------'
3、查看当前tfa主机的状态
当前我们只有一个节点，相关节点的信息如下
tfactl> print status .--------------------------------------------------------------------------------------------. | host | status of tfa | pid | port | version | build id | inventory status | +-------+---------------+-----+-------+------------+----------------------+------------------+ | 12cr2 | running | 912 | 48978 | 12.2.1.0.0 | 12210020161122170355 | complete | '-------+---------------+-----+-------+------------+----------------------+------------------'
4、列出当前tfa的配置信息
tfactl> print config .------------------------------------------------------------------------------------. | 12cr2 | +-----------------------------------------------------------------------+------------+ | configuration parameter | value | +-----------------------------------------------------------------------+------------+ | tfa version | 12.2.1.0.0 | | java version | 1.8 | | public ip network | false | | automatic diagnostic collection | true | | alert log scan | true | | disk usage monitor | true | | managelogs auto purge | false | | trimming of files during diagcollection | true | | inventory trace level | 1 | | collection trace level | 1 | | scan trace level | 1 | | other trace level | 1 | | repository current size (mb) | 19 | | repository maximum size (mb) | 10240 | | max size of tfa log (mb) | 50 | | max number of tfa logs | 10 | | max size of core file (mb) | 20 | | max collection size of core files (mb) | 200 | | minimum free space to enable alert log scan (mb) | 500 | | time interval between consecutive disk usage snapshot(minutes) | 60 | | time interval between consecutive managelogs auto purge(minutes) | 60 | | logs older than the time period will be auto purged(days[d]|hours[h]) | 30d | | automatic purging | true | | age of purging collections (hours) | 12 | | tfa ips pool size | 5 | '-----------------------------------------------------------------------+------------'我们可以用tfactl host add /remove host 增加或者删除grid节点，也就是可以同时收集多个数据库的tfa信息。
5、列出对哪些目录进行了统计
可以看到不仅收集数据库、监听还有安装和操作系统的相关日志，看来功能很强大。
tfactl> print directories

当让您也可以增加或者删除目录，命令如下
增加目录
tfactl directory add dir [ -public ]
[ -exclusions | -noexclusions | -collectall ]
[ -node all | n1,n2,... ]
删除目录 tfactl directory remove dir [ -node all | n1,n2,... ]
6、收集日志信息
如果您使用了中文字符集也就是lang=zh_cn.utf-8的话接下来就会出现bug ，illegal parameter passed to diagcollection -z
[root@12cr2 ~]# echo $lang zh_cn.utf-8 [root@12cr2 ~]# tfactl diagcollect -database prod1 collecting data for the last 12 hours for this component ... collecting data for all nodes collection id : 2017032116573212cr2 detailed logging at : /u01/app/oracle/tfa/repository/collection_二_3月_21_16_57_32_cst_2017_node_all/diagcollect_20170321165732_12cr2.log illegal parameter passed to diagcollection -z failed这个错误原因找了很久，找不到这个logging 的日志，度娘是找不到相关信息的，最终猜想应该是文件中包含了中文名称导致收集失败，试着将字符集换成英文，结果成功了
[root@12cr2 ~]# export lang=en_us [root@12cr2 ~]# echo $lang en_us [root@12cr2 ~]# tfactl diagcollect -database prod1 collecting data for the last 12 hours for this component ... collecting data for all nodes collection id : 2017032117030312cr2 detailed logging at : /u01/app/oracle/tfa/repository/collection_tue_mar_21_17_03_03_cst_2017_node_all/diagcollect_20170321170303_12cr2.log 2017/03/21 17:03:07 cst : collection name : tfa_tue_mar_21_17_03_03_cst_2017.zip 2017/03/21 17:03:07 cst : collecting diagnostics from hosts : [12cr2] 2017/03/21 17:03:07 cst : scanning of files for collection in progress... 2017/03/21 17:03:07 cst : collecting additional diagnostic information... 2017/03/21 17:03:12 cst : getting list of files satisfying time range [03/21/2017 05:03:07 cst, 03/21/2017 17:03:12 cst] 2017/03/21 17:03:13 cst : collecting adr incident files... 2017/03/21 17:03:29 cst : completed collection of additional diagnostic information... 2017/03/21 17:03:33 cst : completed local collection .---------------------------------. | collection summary | +-------+-----------+------+------+ | host | status | size | time | +-------+-----------+------+------+ | 12cr2 | completed | 63kb | 26s | '-------+-----------+------+------' logs are being collected to: /u01/app/oracle/tfa/repository/collection_tue_mar_21_17_03_03_cst_2017_node_all /u01/app/oracle/tfa/repository/collection_tue_mar_21_17_03_03_cst_2017_node_all/12cr2.tfa_tue_mar_21_17_03_03_cst_2017.zip顺利收集成功，tfa作为新出来的工具，在一些细节方面可能支持不太好，本章先到收集，下一章讲演示，查询剪切后日志信息。
