2013.04.30 :: java.sql.SQLException: Already closed.

JAVA/iBatis 2013. 4. 30. 08:42

java.sql.SQLException: Already closed.

error: java.sql.SQLException: Already closed. oracle
상황 : 이상없이 잘 사용하던 커넥션이 한번씩 끊긴다. 이후 재사용시에는 무리없는 활동을 보여준다.
이유 : 데이터베이스 입장에서 오랫동안 휴면되는 커넥션은 불필요하다고 판단하고, 끊어버린다. 때문에 커넥션풀 설정시 연결 확인용 쿼리를 지정해주어야 한다.
