Oracle DAX fallbacks


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

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... (1 Reply)

dh_consoledata - declare console data files SYNOPSIS
dh_consoledata [debhelper options] [-n] DESCRIPTION
This program is meant to assist in building a package that provides data files for the console. It is still in the early stages of developement, and many features are still missing or partly implemented. Please look at /usr/share/doc/console-common/TODO for more details. For now this program takes a debian/package.keymaps file, installs in in the package build directory, and creates the debian/package.config and debian/package.templates files. It also makes the ${console:depends} variable available for the control file. This variable should be referenced in the Depends field, as should ${perl:depends} if you use dh_perl (which you should call anyway, since your package will include a perl debconf script). It should ultimately allow to declare fonts and SFM fallbacks. OPTIONS
-n, --noscripts Do not modify postinst/postrm scripts. -d Install the debconf templates and config script (and add the postinst fragment, unless -n is also specified), even if there is no debian/package.keymaps file. This is normally intended for internal use, be careful that the name of the option and its semantics will probably change in the near future, to accomodate for new needs. SEE ALSO
debhelper(1) This program is an extention to debhelper. AUTHOR
