DAX fallbacks

Hi,

could you explain what DAX fallbacks mean in detail and how to avoid them? Or is it ok to have fallbacks?

Unfortunately googling does not help...

MANpage says: fallbacks == Number of commands completed by the software, which DAX could not complete

OK, but why and what does it mean for the DB?

Running RAC on M7 with InMemory:

1st node=DAX commands 35.608.411 with 18 fallbacks

2nd node=DAX commands 63.563.607 with 2.656.188 fallbacks

Is it just a bad day for the second node? Any ideas how I could dig deeper at OS or DB level?

Thanks in advance and regards

- Martin

What is the difference between o_direct and DAX with ext4 filesystem?

I'm trying to understand the difference between o_direct flag of open system call and dax (direct access) with ext4 filesystem. According to my understanding both bypass page cache. But I'm still unclear about the crucial difference between these 2 techniques. If there is a huge difference...

DXmCreateCursor(3X)													       DXmCreateCursor(3X)

NAME

       DXmCreateCursor - Creates a specific cursor.

SYNOPSIS

       Cursor DXmCreateCursor(
	       Widget widget,
	       int cursorkind );

PARAMETERS

       The widget from which display information is obtained.  An integer that represents the type of cursor, as follows:

	      ---------------------------------------------------------------
	      Value				Cursor Description
	      ---------------------------------------------------------------
	      decw$c_wait_cursor(4)		A watch
	      decw$c_questionmark_cursor(54)	A question mark
	      decw$c_inactive_cursor(6)	A  caution  ("do not enter")
						symbol
	      ---------------------------------------------------------------

	      The following X Window System fallbacks are provided in the event the DECwindows-specific cursors cannot be loaded:

	      -----------------------------------------------
	      DECwindows-Specific Cursor   X Fallback
	      -----------------------------------------------
	      decw$c_wait_cursor	   XC_watch
	      decw$c_questionmark_cursor   XC_question_arrow
	      decw$c_inactive_cursor	   XC_circle
	      -----------------------------------------------

	      You can specify additional cursor symbols by examining the /usr/include/X11/decwcursor.h file.  (X Window System fallbacks are  pro-
	      vided for each of those cursors as well.)

DESCRIPTION

       The  DXmCreateCursor  routine  enables  you  to create a cursor that displays as a watch, question mark, or caution ("do not enter") symbol
       (these are the most frequently used cursor symbols).

RETURN VALUES

       The identifier (cursor ID) of the created cursor.
