NAME

       Apache2::Resource - Limit resources used by httpd children

Synopsis
	 PerlModule Apache2::Resource
	 # set child memory limit in megabytes
	 # default is 64 Meg
	 PerlSetEnv PERL_RLIMIT_DATA 32:48

	 # linux does not honor RLIMIT_DATA
	 # RLIMIT_AS (address space) will work to limit the size of a process
	 PerlSetEnv PERL_RLIMIT_AS 32:48

	 # set child cpu limit in seconds
	 # default is 360 seconds
	 PerlSetEnv PERL_RLIMIT_CPU 120

	 PerlChildInitHandler Apache2::Resource

Description
       "Apache2::Resource" uses the "BSD::Resource" module, which uses the C function "setrlimit" to set limits on system resources such as memory
       and cpu usage.

       Any "RLIMIT" operation available to limit on your system can be set by defining that operation as an environment variable with a "PERL_"
       prefix.	See your system "setrlimit" manpage for available resources which can be limited.

       The following limit values are in megabytes: "DATA", "RSS", "STACK", "FSIZE", "CORE", "MEMLOCK"; all others are treated as their natural
       unit.

       If the value of the variable is of the form "S:H", "S" is treated as the soft limit, and "H" is the hard limit.	If it is just a single
       number, it is used for both soft and hard limits.

Defaults
       To set reasonable defaults for all RLIMITs, add this to your httpd.conf:

	 PerlSetEnv PERL_RLIMIT_DEFAULTS On
	 PerlModule Apache2::Resource

NAME

       Apache2::MPM - Perl API for accessing Apache MPM information

Synopsis
	 use Apache2::MPM ();

	 # check whether Apache MPM is threaded
	 if (Apache2::MPM->is_threaded) { do_something() }

	 # which mpm is used
	 my $mpm = lc Apache2::MPM->show;

	 # query mpm properties
	 use Apache2::Const -compile => qw(:mpmq);
	 if (Apache2::MPM->query(Apache2::Const::MPMQ_STATIC)) { ... }

Description
       "Apache2::MPM" provides the Perl API for accessing Apache MPM information.

API

       "Apache2::MPM" provides the following functions and/or methods:

   "query"
       Query various attributes of the MPM

	 my $query = Apache2::MPM->query($const);

       obj: $class ( "Apache2::MPM class" )
	   the class name

       arg1: $const ( "Apache2::Const :mpmq group constant" )
	   The MPM attribute to query.

       ret: $query ( boolean )
	   the result of the query

       since: 2.0.00

       For example to test whether the mpm is static:

	 use Apache2::Const -compile => qw(MPMQ_STATIC);
	 if (Apache2::MPM->query(Apache2::Const::MPMQ_STATIC)) { ... }

   "is_threaded"
       Check whether the running Apache MPM is threaded.

	 my $is_threaded = Apache2::MPM->is_threaded;

       obj: $class ( "Apache2::MPM class" )
	   the class name

       ret: $is_threaded ( boolean )
	   threaded or not

       since: 2.0.00

       Note that this functionality is just a shortcut for:

	 use Apache2::Const -compile => qw(MPMQ_IS_THREADED);
	 my $is_threaded = Apache2::MPM->query(Apache2::Const::MPMQ_IS_THREADED);

   "show"
       What mpm is used

	 my $mpm = Apache2::MPM->show();

       obj: $class ( "Apache2::MPM class" )
	   the class name

       ret: $mpm ( string )
	   the name of the MPM. e.g., "Prefork".

       since: 2.0.00
