[-webSSL]	Use encrypted (HTTPS) connections
[-browser]	Start a browser connecting to the web server
[-tcp]	Start the TCP server
[-tcpAllowOthers]	Allow other computers to connect - see below
[-tcpDaemon]	Use a daemon thread
[-tcpPort <port>]	The port (default: 9092)
[-tcpSSL]	Use encrypted (SSL) connections
[-tcpPassword <pwd>]	The password for shutting down a TCP server
[-tcpShutdown "<url>"]	Stop the TCP server; example: tcp://localhost
[-tcpShutdownForce]	Do not wait until all connections are closed
[-pg]	Start the PG server
[-pgAllowOthers]	Allow other computers to connect - see below
[-pgDaemon]	Use a daemon thread
[-pgPort <port>]	The port (default: 5435)

Parameters:

args - the command line arguments

Throws:

SQLException

runTool

public void runTool(String... args)
             throws SQLException

Description copied from class: Tool

Run the tool with the given output stream and arguments.

Specified by:

runTool in class Tool

Parameters:

args - the argument list

Throws:

SQLException

shutdownTcpServer

public static void shutdownTcpServer(String url,
                     String password,
                     boolean force,
                     boolean all)
                              throws SQLException

Shutdown one or all TCP server. If force is set to false, the server will not allow new connections, but not kill existing connections, instead it will stop if the last connection is closed. If force is set to true, existing connections are killed. After calling the method with force=false, it is not possible to call it again with force=true because new connections are not allowed. Example:

 Server.shutdownTcpServer(
     "tcp://localhost:9094", password, true, false);
 

Parameters:

url - example: tcp://localhost:9094

password - the password to use ("" for no password)

force - the shutdown (don't wait)

all - whether all TCP servers that are running in the JVM should be stopped

Throws:

SQLException
