                 throws org.python.core.PyException

Parameters:

args - Command line arguments.

Throws:

org.python.core.PyException

setConnection

Set the DBConnection.

exit

public static void exit(int code)

testProxy

public static void testProxy(java.lang.String server,
                             java.lang.String database,
                             java.lang.String user,
                             java.lang.String passwd,
                             java.lang.String sql)

testConn

public static void testConn(java.lang.String dbType,
                            java.lang.String server,
                            java.lang.String port,
                            java.lang.String database,
                            java.lang.String user,
                            java.lang.String passwd)

This method can be used to test encryption and checksum connection schemes.

exec

public static boolean exec(java.lang.String cmd)

On Windows machines, exec() requires "cmd /c" to envoke the command prompt. The boolean ISDOS is defaulted to false but can be set manually or via the command line. This returns true if the command ran successfully and false if the command returned a non 0 exit code or any exceptions occurred.

Notes:

BufferedInputStream.available() should say if there is data in the stream but it doesn't seem to work correctly. It seems that in many conditions you must first read from the stream which is not useful., ISDOS should be a parameter., Linux used to require "sh -c" but doesn't anymore. Not sure why.

exec

public static boolean exec(java.lang.String cmd,
                           boolean printOutput)

getExec

public static java.lang.String getExec(java.lang.String cmd)

getExec

public static java.lang.String getExec(java.lang.String cmd,
                                       boolean incError)

execFull

public static boolean execFull(java.lang.String cmd,
                               boolean wait)

On Windows machines, exec() requires "cmd /c" to envoke the command prompt. The boolean ISDOS is defaulted to false but can be set manually or via the command line. This returns true if the command ran successfully and false if the command returned a non 0 exit code or any exceptions occurred.

Notes:

ISDOS should be a parameter.

getSystemProperty
