I am running HP-UX B.11.11.
I'm increasing a parameter for a database engine so that it uses more memory to buffer the disk drive (to speed up performance). I have over 5GB of memory not being used.
But when I try to start the DB with the increased buffer parameter I get told.

I need to create a shared library to access an in memory DB. The DB is not huge, but big enough to make it cumbersome to carry around in every single process using the shared library. Luckily, it is pretty static information, so I don't need to worry much about synchronizing the data between... (12 Replies)

I am writing a shared library in Linux (but compatible with other UNIXes) and I want to allow multiple instances to share a piece of memory -- 1 byte is enough. What's the "best" way to do this? I want to optimize for speed and portability.
Obviously, I'll have to worry about mutual exclusion. (0 Replies)

vimtutor
VIMTUTOR(1) General Commands Manual VIMTUTOR(1)
NAME
vimtutor - the Vim tutor
SYNOPSIS
vimtutor [-g] [language]
DESCRIPTION
Vimtutor starts the Vim tutor. It copies the tutor file first, so that it can be modified without changing the original file.
The Vimtutor is useful for people that want to learn their first Vim commands.
The optional argument -g starts vimtutor with gvim rather than vim, if the GUI version of vim is available, or falls back to Vim if gvim is
not found.
The optional [language] argument is the two-letter name of a language, like "it" or "es". If the [language] argument is missing, the lan-
guage of the current locale will be used. If a tutor in this language is available, it will be used. Otherwise the English version will
be used.
Vim is always started in Vi compatible mode.
FILES
/usr/share/vim/vim73/tutor/tutor[.language]
The Vimtutor text file(s).
/usr/share/vim/vim73/tutor/tutor.vim
The Vim script used to copy the Vimtutor text file.
AUTHOR
The Vimtutor was originally written for Vi by Michael C. Pierce and Robert K. Ware, Colorado School of Mines using ideas supplied by
Charles Smith, Colorado State University. E-mail: bware@mines.colorado.edu.
It was modified for Vim by Bram Moolenaar. For the names of the translators see the tutor files.
