iwinv 에서 블록스토리지에 zfs 파일시스템 구성

반응형

개요

  • 국내에서 제법 저렴한 호스팅 서비스인 iwinv에서 제공하는 서비스 활용법중에 하나...
  • 기본적으로 iwinv 에서 제공하는 blockstorage를 이용하여 zfs 파일 시스템을 생성할수 있다. 기본 가이드는 lvm을 이용하는것으로 가이드 하지만 zfs도 생성 가능
  • cpu를 조금 더 사용하여 파일시스템 사용 효율을 극대화 할수 있다.
    zfs활용예시
  • 설치는 openzfs 가 아닌 apt로 간단히 설치

기본으로 vm-lite (ubuntu 20버전) 과 blockstorage(예제로50GB) 생성

[Tomcat] Windows에서 콘솔 화면 한글 깨짐 조치

Computer_IT/JAVA2020. 10. 15. 17:37

증상

  • Windows 명령창에서 Tomcat 구동시 한글이 모두 깨짐

원인

  • 명령 프롬프트 창과 tomcat logging 기본 인코딩(UTF-8)이 틀려서 발생

조치방법

  1. 레지스트리를 편집하여 "명령 프롬프트" 인코딩 변경
  2. tomcat에서 남기는 로그 인코딩 변경 ( tomcat9 버전 기준 )
1catalina.org.apache.juli.AsyncFileHandler.encoding = UTF-8
2localhost.org.apache.juli.AsyncFileHandler.encoding = UTF-8
3manager.org.apache.juli.AsyncFileHandler.encoding = UTF-8
4host-manager.org.apache.juli.AsyncFileHandler.encoding = UTF-8
java.util.logging.ConsoleHandler.encoding = UTF-8

UTF-8 부분 모두 EUC-KR로 변경후 저장

[PostgreSQL] PostgreSQL Disadvantages - 단점/불편한점

Computer_IT/DBMS2019. 5. 20. 22:54
반응형

컬럼 사이즈 변경시 주의점

컬럼 사이즈를 변경할때 관련된 view가 있으면 view를 drop 후에 새로 생성해야 함.
view개수가 많을수록 번거러움은 커진다.

  1. drop view ...
  2. alter table ... alter column ...
  3. create view

파일 시스템 Full

데이터가 적재되는 파일 시스템이 100% 도달해버리면 PostgreSQL 프로세스가 내려간다. (종료됨)

vacuum 관리

vacuum이 불이의 이유로 수행이 안될경우 db자체가 정지하며 재생성 작업을 해주어야 한다.

Jeus Postgresql datasource logintimeout 오류

Computer_IT/오류메세지2018. 4. 8. 00:44
반응형

사례 

Tmax의 Jeus에서 PostgreSQL 설정후 [TEST] 수행시  logintimeout 에러가 발생


원인 : 

1. Driver Class를 org.postgresql.Driver 로 설정한것이 문제

2. JEUS 에서 사용하기 위해선  javax.sql.CommonDataSource 를 상속 받아 구현한 class가 필요함


해결 : 

아래 Class 로 설정하면 에러 발생하지 않음 ( postgresql jdbc 드라이버에 포함되어있음 )

Driver Class : org.postgresql.jdbc3.Jdbc3PoolingDataSource


참고자료 : 

org.postgresql.jdbc3.Jdbc3PoolingDataSource

https://jdbc.postgresql.org/development/privateapi/org/postgresql/jdbc3/Jdbc3ConnectionPool.html

(setTimeout이 구현되어있음)


org.postgresql.Driver  : 

https://jdbc.postgresql.org/development/privateapi/org/postgresql/Driver.html

(setTimeout이 없음)


추가적으로

JEUS는 other 선택시 derby 세팅을 기본으로 하다 보니  create=true;  옵션이 들어가다 보니 문제가 발생하니 "create=true;" 옵션 제거도 필요함

DB_JDBC설정DB_JDBC설정

JDBC설정 화면




URL Format과 DriverClass 를 Ctrl+C , Ctrl+V만 해도 기본적인 DB연결 문자열은 바로 생성 가능

Class.forName("net.sourceforge.jtds.jdbc.Driver");

conn = DriverManager.getConnection("jdbc:jtds:sqlserver://<server>:<port1433>;DatabaseName=<database>", "user", "password");







장점 : 

1. Java기반으로 제작된 프로그램

2. Java개발시 사용되는 JDBC연결을 통해 JDBC를 지원하는 모든 DB연결가능

    (지원되지 않는 DB라도 JDBC 드라이버만 있으면 기본적인 연결 및 쿼리 가능) ex) Cubrid, Tibero

3. 상용 프로그램으로 꾸준한 업데이트 지원

4. 데이터를 손쉽게 Chart로 표현 가능

5. 설치된경로\resources\profiles 에 DB별로 조회가능한 Dictionary 조회 쿼리 존재

6. DB별로 특성화된 구조로 표현




단점 :

1. 대량의 데이터 Fetch 시에 Memory 점유율(Java메모리)이 높음

2. 무료로 사용가능하나 무료버전은 많은 기능이 제약됨

3. LongRun 쿼리 Stop이 불가할땐 재시작 해야함

4. 범용성을 지니다 보니 전문적인 admin 부분에선 약함

5. 초반 설치시 Editor에서 한글을 사용하기 위해선 한글 Font 지정 필요

   Tools->Tool Properties -> [General] -> General -> Apperance -> Fonts

6. Pro버전 라이센스가 비쌈-1copy $179 (여러 DB를 사용해야 하는 직업을 가진 사람은 적당한 툴)

인터넷 다운로드시 Olleh KT IPTV 화면 끊김(영상 버퍼링),모자이크 줄이는 방법

Computer_IT/IPTV2014. 5. 25. 22:08
반응형


0:00~00:12 --++ TV시청만 할경우

0:12~00:47 --++ 인터넷 다운로드 시

00:47~끝    --++ TV만 시청시



IPTV 구성

벽-> 올레셋탑-> IPTIME공유기 -> TV, PC, 등등등... 차례대로 연결되어있음.


증상

평소에는 아무런 증상이 없다가도...

KT IPTV를 시청중 PC에서 다운로드 대역을 100% 사용하게 되면

그 즉시 IPTV 시청중인 화면은 위 동영상과 같이 화면에 버퍼링(모자이크) 같은 현상이 일어남.




해결(속도를 줄여서 증상을 없게 하는...)


대부분 공유기의 기능에 있는 QOS 서비스를 활성화 시켜서 우회 할수 있다.

대략 KT IPTV는 10M-20M 의 대역폭을 사용함.

그부분을 공유기를 통해서 임의로 제한을 걸게 되면 끊김 현상이 없어짐.


IPTIME 공유기의 경우...

100Mbps 라인의 경우 90-75사이에서 줄여 나가면서 끊기지 않는 최대치로 설정
