제가 odbc 와 oledb 를 연결하여서 프로그램을 사용하고 있는데요

예전엔 안그랬는데 새로 sybase를 깔고 나서부터 이런 오류가 자주 납니다.

서비스에서 사이베이스 서버를 시작을 하면 연결이 잘 되는데

조금만 있으면 jdbc 연결오류가 나면서 socket이 닫혔다고 오류가 납니다.

그래서 서비스를 중지했다 다시 시작하면 이런오류가 안납니다

예전에는 한번 서비스를 시작해 놓으면 연결끊김없이 잘 되었었는데

멀 하려고만 하면 연결이 끊겼다고 오류가 나네요...

연결 끊기지 않고 계속 쓰려면 따로 멀 지정해 줘야 하나요?

연결 끊길때마다 서비스를 다시 시작하고 있습니다...

방법 부탁드리구요

빠른답변 부탁드려요,,, 지방에 일 나왔는데 계속이러면 안되거든요

부탁드립니다

오류 메시지 입니다

java.sql.SQLException: JZ006: IOException 발견: com.sybase.jdbc2.jdbc.SybConnectionDeadException: JZ0C0: 연결이 이미 닫혔습니다.
