使用連接池，你只需添加
validationQuery=」SELECT CURRENT DATE FROM sysibm.sysdummy1」我的context.xml ？如果是的話，你的服務器可能會消除空閒的連接（或重新啓動數據庫服務器）。您是否爲連接池配置了驗證查詢，以便在將連接提供給您的webapp之前檢查該查詢？如果沒有，那就這樣做。 – Andreas'<資源 \t \t名稱= 「JDBC/DB2_IBS_BSV」 \t \t AUTH = 「容器」 \t \t類型= 「javax.sql.DataSource中」 \t \t用戶名= 「*******」 \t \t密碼= 「******」 \t \t driverClassName = 「com.ibm.as400.access.AS400JDBCDriver」 \t \t URL = 「JDBC：AS400：// SV4013CB /」 \t \t maxActive = 「50」 \t \t maxIdle =「30」 />' –
