如何在服务器模式下运行H2数据库?
我需要从我的应用程序以服务器模式启动 H2 数据库。尝试了以下代码:
server = Server.createTcpServer().start();
下面是连接的属性:
javabase.jdbc.url = jdbc:h2:tcp://localhost:9092/nio:~/source/db/database/db;AUTO_SERVER=TRUE
javabase.jdbc.driver = org.h2.Driver
javabase.jdbc.username = sa
javabase.jdbc.password =
当我运行该程序时,我得到以下错误:
client.db.exception.DAOException: org.h2.jdbc.JdbcSQLException: Database may be already in use: "Locked by another process". Possible solutions: close all other connection(s); use the server mode [90020-164]
