Today (Saturday) We will make some minor tuning adjustments to MySQL.

You may experience 2 up to 10 seconds "glitch time" when we restart MySQL. We expect to make these adjustments around 1AM Eastern Daylight Saving Time (EDT) US.

Tools What Is The RPM?

Hello,

Do you know what is the RPM?

RPM is the RPM Package Manager. It is an open packaging system available for anyone to use. It allows users to take source code for new software and package it into source and binary form such that binaries can be easily installed and tracked and source can be rebuilt easily. It also maintains a database of all packages and their files that can be used for verifying packages and querying for information about files and/or packages.

Red Hat, Inc. encourages other distribution vendors to take the time to look at RPM and use it for their own distributions. RPM is quite flexible and easy to use, though it provides the base for a very extensive system. It is also completely open and available, though we would appreciate bug reports and fixes. Permission is granted to use and distribute RPM royalty free under the GPL.

RPM is an open packaging system that is available for anyone to use. It works on all Linux as well as currently on various other UNIX flavours: IRIX, Solaris, SunOS, AIX, HP/UX, AmigaOS, and FreeBSD.

I disagree.

RPM is good.
But. For each OS you must use OS's own packet manager.

for example:
pkg_add and ports in FreeBSD (rpm works only in linux-compatability mode)
pkgadd in Solaris
emegre in Gentoo
etc.
