서버 운영 중 간헐적으로 데이터 접근 불가하다는 에러가 발생합니다. 

몇 분정도 에러 페이지가 뜨다가 다시 정상 운영되는 식으로 에러가 발생합니다. 

톰캣 에러 로그는 이렇습니다.

-21024 는  Request timed out 에러라는 것과, cubrid_broker.conf 값과, application의 dbcp 설정 값을 확인해보라는 답변은 찾을 수 있었습니다.

운영 중인 서버의 설정 값을 바꿔 보기 전에 설정 값을 바꾸는 조치가 적절한지, 다른 원인이 있는지 여쭤보고 싶습니다.

 

DBMS는 두 개의 어플리케이션이 함께 사용하고 있습니다. 두 어플리케이션 모두 설정 값은 같습니다.

 

* application의 dbcp 설정 값

<property name="initialSize" value="10" />

<property name="maxIdle"     value="10" />

<property name="maxActive"   value="10" />

 

* cubrid_broker.conf 설정 값
