PHP7 esta listo para ser liberado

jueves, diciembre 3rd, 2015

Luego de aparentemente unos años de desarrollo PHP 7 esta listo para ver la luz, es interesante que esta distribución se enfoca en lograr mayor velocidad con menor cantidad de recursos, por lo visto las modificaciones al codigo actual (dependiendo como haya sido construido) solo deberá sufrir un par de modificaciones, y todo será más rápido

Habilitar el profiling en Moodle a través de Xhprof

domingo, noviembre 29th, 2015

La opción de Moodle para habilitar el modo profiling esta ubicada en Administracion del sitio > Desarrollo > Profiling

En este caso en imagen debes establcer la opción de habilitación y además establecer un ‘*’ para que pueda hacer un profiling a todas las paginas.

moodle_profiling

Luego en Profiling runs, podras ver la lista de ejecuciones de los distintos accesos a las pagina, al ver el detalle te podrás encontrar con cosas como las siguientes

Instalando xhprof para profiling de PHP

domingo, noviembre 29th, 2015

Una de las herramientas para hacer profiling en PHPes xhprof. Al momento de escribir este articulo estaba en su versión 0.9.4

Los pasos a seguir en su instalacion en mi caso en CEntOS son:

yum install graphviz
wget https://pecl.php.net/get/xhprof-0.9.4.tgz
tar xzf xhprof-0.9.4.tgz 
cd xhprof-0.9.4/extension/
phpize
./configure
make
make install

Luego editas el INI

vi /etc/php.d/xhprof.ini

Le estableces

[xhprof]
extension=xhprof.so
xhprof.output_dir="/tmp/xhprof"

Antes de reiniciar apache crea la carpeta para que guarde los datos del profiling

cd /tmp
mkdir xhprof
chown apache.apache xhprof/
ln -s /var/log/xhprof-0.9.4/xhprof_html xhprof
systemctl restart httpd

Libraries have been installed in:
   /root/oraclePhp/oci8-1.4.7/modules

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-Wl,-rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

ORA-24408 Error de conexion a Oracle desde Moodle

jueves, febrero 28th, 2013

En una configuracion dond participan 7 servidores moodle apuntando a la misma base de datos Oracle 11g se produjo el siguiente error

Debug info: ORA-24408: could not generate unique server group name
Error code: dbconnectionfailed
Stack trace:

Esto se debe a que el nombre del host esta mal configurado o lo resuelve mal. Por lo que si editas el achivo /etc/sysconfig/network

[root@servername mnt]# more /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=servername

Debe ser igual al configurado en /etc/hosts, aqui yo convenientemente introduzco el servername en primer lugar, para que sea lo primero en reconocer.
