OpenNebula

Find attached a patch for 3.8.5 to enable new parameters to increase the number of xmlrpc sockets. To compile it follow the steps:

* Install libcurl development libraries

* Download a newer xmlrpmc-c library:

$ svn checkout http://svn.code.sf.net/p/xmlrpc-c/code/stable xmlrpc-c

* Set CXXFLAGS so it compiles for x86_64:

$ export CXXFLAGS=-fPIC

* Configure, make, make install with a prefix:

$ ./configure --prefix=$PWD/install
$ make
$ make install

* Delete dynamic libraries from xmlrpc dir:

$ rm <xmlrpc dir>/lib/*.so <xmlrpc dir>/lib/*.so.*

* Set path to point to xmlrpc bin dir:

$ export PATH=<xmlrpc dir>/bin:$PATH

* Compile OpenNebula after applying the patch

$ git clone git://git.opennebula.org/one.git
$ cd one
$ git checkout release-3.8.5
$ git apply xmlprc.patch
$ scons -j2 mysql=yes

Once this OpenNebula is installed, you can control the xmlrpc server parameters through oned.conf configuration:



----------------
These are configuration parameters for oned's xmlrpc-c server



MAX_CONN: Maximum number of simultaneous TCP connections the server

will maintain



MAX_CONN_BACKLOG: Maximum number of TCP connections the operating system

will accept on the server's behalf without the server accepting them from

the operating system



KEEPALIVE_TIMEOUT: Maximum time in seconds that the server allows a

connection to be open between RPCs



KEEPALIVE_MAX_CONN: Maximum number of RPCs that the server will execute on

a single connection



TIMEOUT: Maximum time in seconds the server will wait for the client to

do anything while processing an RPC

#MAX_CONN = 15
#MAX_CONN_BACKLOG = 15
#KEEPALIVE_TIMEOUT = 15
#KEEPALIVE_MAX_CONN = 30


#TIMEOUT = 15
