Question Synchronize DataBase Table Between Machines Via SSH?

Hello

I have 2 servers that need a database table to be one way synchronized (server A needs to push the table to server B)

I considered using a FEDERATED DB, but decided against it for my particular application (Server B has several apps that would be calling the table repeatedly, and a local DB to server B makes more sense).

So thinking out loud.... when the DB on server A changes, a mysqldump is performed of the table, is ssh'd to server B, and then mysqldump'd into the table.

This table will change infrequently (monthly perhaps), but would need to be done on demand, so that when the change is made, it is propagated to server B nearly instantly.

My real question is: Is my line of thinking right, or is there a better way to do this?


Any thoughts or input would be greatly welcomed.

Matt

XtGetKeysymTable()														XtGetKeysymTable()

Name
  XtGetKeysymTable - return a pointer to the keycode-to-keysym mapping table of a  display.

Synopsis
  KeySym *XtGetKeysymTable(display, min_keycode_return,
  keysyms_per_keycode_return)
	   Display *display;
	   KeyCode *min_keycode_return;
	   int *keysyms_per_keycode_return;

Inputs
  display   Specifies the display whose table is required.

Outputs
  min_keycode_return
	    Returns the minimum keycode valid for the display.

  keysyms_per_keycode_return
	    Returns the number of keysyms stored for each keycode.

Returns
  The keycode-to-keysym table for display.

Availability
  Release 4 and later.

Description
  XtGetKeysymTable()  returns  a pointer to the Intrinsics' copy of the X server's keycode-to-keysym table, which must not be modified by the
  application.	This table is simply an array of KeySym.  The number of keysyms associated with each keycode is returned in  keysyms_per_key-
  code_return.	 The  first  keysyms  in  the table are for the keycode returned in min_keycode_return.  The keysyms for a keycode k begin at
  index:

     k - min_keycode_return) * keysyms_per_keycode_return

  Any entries in the table that have no keysyms associated with them contain the value NoSymbol.

Usage
  The Intrinsics maintains a table internally to map keycodes to keysyms for each open display.  The Translation Manager uses this table, and
  custom keycode-to-keysym translator procedures (see XtSetKeyTranslator()) and other clients may also need to use it.	Most applications and
  widgets will never need to use this function.

  You should not cache this keysym table but should call XtGetKeysymTable() each time the value is needed, because the table  may  change  at
  any time.
