Session Timeout 값
 
JEUS에서 Session Timeout 값의 설정은 다음과 같이 할 수 있고, 아래 나열한 순서대로 우선순위를 갖게 된다.
 
     ①   web.xml
          <web-app><session-config><session-timeout>   단위 : 분

If Application Server Hang on AIX platform.

To troubleshoot the hang, please collect the following doc during the time that
the hang is occurring. login as "root",

1. netstat -an > netstat.txt (if webserver is remote, gather netstat output on
   Appserver machine AND webserver machine) 
2. ps -ef > ps.txt
3. df -k > df.txt
4. lsof -p [PID of hung appserver] > lsof.txt (You need to install "lsof" utility)
5. Can you serve a static document from the webserver? 
6. tprof -k -s -e -x sleep 60 
7. ./dbxtrace_aix.sh -a [PID of hung appserver] > dbxtrace.txt (wait until finished)
8. WAIT TWO MINUTES 
9. kill -3 [PID of hung appserver] 
10. WAIT TWO MINUTES 
11. kill -3 [PID of hung appserver] 
12. WAIT TWO MINUTES 
13. kill -3 [PID of hung appserver] 

The kill -3's should create javacore.txt files in the working directory of WAS,
normally Websphere\Appserver\bin directory.


Please send in the following files: 
1. Everything in <was root>\logs directory (from the WebSphere machine) 
2. If the webserver is remote, send the trace.log.<webserver name>.<date> (3.5.X), 
   native.log (4.0.X), or http_plugin.log (5.0.X) file from the webserver machine. 
3. dbxtrace.txt 
4. All javacore?????.txt files created 
5. netstat.txt, ps.txt, df.txt
6. Send in all files generated by tprof (especially  _prof.all). These files will
   be in the directory from which the tprof command was run and will begin with "_".
7. Additionally, for WebSphere,
   (1) uname -a > uname.txt
   (2) lslpp -i |grep AIX_ML | sort > aix_sw.txt
   (3) errpt -a > errpt.txt
   (4) httpd.conf of HTTP Server
   (5) WAS_HOME/bin/admin.config
   (6) WAS_HOME/bin# ./XMLConfig.sh -adminNodeName <server> -export xmlconfig.xml
       (send "xmlconfig.xml")
   (7) WAS_HOME/properties/com/ibm/websphere/product.xml

8. If you think the problem caused by JDBC Connection Pool, send me all Java source
  programs you have.

2. dbxtrace.sh
a. "dbx" 라는 프로그램이 설치되어 있는지 확인해 보십시요. 만약 설치되어 있지
  않다면, 설치를 하도록 하십시요. 대부분 이미 설치되어 있을 겁니다.

b. 아래에 첨부한 dbxtrace.sh 라는 shell script 를 다운받아 적당한 디렉토리에
  넣어두고, 실행권한을 부여하십시요.
  # cp /tmp/dbxtrace.sh /usr/local/bin/
  # chmod 755 /usr/local/bin/dbxtrace.sh

c. root 유저에서 다음의 명령을 통해 system fullcore 옵션을 true 로 변경하시요.

  옵션확인방법 : lsattr -El sys0 | grep fullcore
  옵션변경방법 : chdev -a fullcore=true -l sys0

d. /usr/WebSphere/AppServer/bin/ 디렉토리에 있는 javacore* 및 core 파일은
  (현재 개발중이시니) 더이상 필요없으며, 가급적 삭제하시고, 각종 로그들도
  삭제하여 /usr 디스크의 free space 를 가급적 500MB 이상을 확보하십시요.
