TcpServer

The TCP server implements the native H2 database server protocol. It supports multiple client connections to multiple databases (many to many). The same database may be opened by multiple clients. Also supported is the mixed mode: opening databases in embedded mode, and at the same time start a TCP server to allow clients to connect to the same database over the network.

Methods
static String	getManagementDbName(int port) Get the database name of the management database.
static String	getManagementDbName(int port) Get the database name of the management database. The management database contains a table with active sessions (SESSIONS). Parameters: port - the TCP server port Returns: the database name (usually starting with mem:)
static void	shutdown(String url, String password, boolean force, boolean all) Stop the TCP server with the given URL.
static void	shutdown(String url, String password, boolean force, boolean all) throws SQLException Stop the TCP server with the given URL. Parameters: url - the database URL password - the password force - if the server should be stopped immediately all - whether all TCP servers that are running in the JVM should be stopped
static void	stopServer(int port, String password, int shutdownMode) Stop a running server.
static void	stopServer(int port, String password, int shutdownMode) Stop a running server. This method is called via reflection from the STOP_SERVER function. Parameters: port - the port where the server runs, or 0 for all running servers password - the password (or null) shutdownMode - the shutdown mode, SHUTDOWN_NORMAL or SHUTDOWN_FORCE.
void	addConnection(int id, String url, String user) Add a connection to the management database.
void	addConnection(int id, String url, String user) Add a connection to the management database. Parameters: id - the connection id url - the database URL user - the user name
boolean	allow(Socket socket) Check if this socket may connect to this server.
boolean	allow(Socket socket) Check if this socket may connect to this server. Remote connections are not allowed if the flag allowOthers is set. Parameters: socket - the socket Returns: true if this client may connect
void	cancelStatement(String sessionId, int statementId) Cancel a running statement.
void	cancelStatement(String sessionId, int statementId) Cancel a running statement. Parameters: sessionId - the session id statementId - the statement id
String	checkKeyAndGetDatabaseName(String db) If no key is set, return the original database name.
String	checkKeyAndGetDatabaseName(String db) If no key is set, return the original database name. If a key is set, check if the key matches. If yes, return the correct database name. If not, throw an exception. Parameters: db - the key to test (or database name if no key is used) Returns: the database name Throws: DbException - if a key is set but doesn't match
