[users@httpd] Apache Restarting

[ge...@yahoo.com]

Hi everybody,

I would like to know what really happen when apache is
restarted. This is because I need to know the risks of
restarting during production time. 

I mean, if, for example, a php is being attended and
at that moment I restart, does apache will wait until
the php finishes and give the generated response or it
will just kill every running/pending process? The same
question applies about mod_jk when attending java
proceses.

In fact, is there any risk about missing financial
transactions?

Thank you ;-)

This is discussed here:
http://httpd.apache.org/docs/2.2/stopping.html

The punchline is that, as long as you use a graceful restart, no
existing requests or connections are lost.

But whether there is any "risk about missing financial transactions"
depends on a whole lot of things beside the apache restart code ;-)
