Instalando el InstantClient de Oracle para PHP en Linux

Aun cuando puedes encontrar en esta página una descripcion detallada de la instalación, aqui te muestro una instalación paso a paso de los comando aplicados en el orden que se expresa para linux, exceptuando la de php-devel que la instale debido a que no estaba. Esta instalación se hizo en RedHat 6.1.

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.

Cambiando algoritmo de encriptamiento de la password en linux

En algunos casos, si requieres cambiar o actulizar el algoritmo de encriptamiento de la password de linux, debes aplicar lo siguiente para saber que algoritmo tienes

authconfig --test | grep hashing

Respuesta

password hashing algorithm is sha512

Para cambiarlo aplicar

authconfig --passalgo=md5 --update

Es “downgrade” de password (debido a que MD5 es masinseguro que sha512) lo necesite hacer debido a Error SQL30082N Reason Code 15 (o 24) en DB2

Esto afecta a todos los usuarios por lo que ellos deben cambiar su password despues del proximo ingreso. Para obligarlos

chage -d 0 nombre_de_usuario

Error SQL30082N Reason Code 15 (o 24) en DB2

Si ya estas trabajando con DB2 9.1 o superior pero en los últimos sistemas operativos de linux, puede aparecer el error

SQL30082N Security processing failed with Reason Code 15
"Security processing at the server failed "

o

SQL30082N Security processing failed with Reason Code 24
"USERNAME AND/OR PASSWORD INVALID "

La razon la encontre aquí y tiene que ver con el algoritmo de encriptación de la password. Recordemos que DB2 utiliza el usuario de sistema operativo, a él es quién tu le asignas los permisos para accesar a una base de datos o a un esquema de DB2.

El problema es que actualmente los sistemas operativos Linux vienen con el algoritmo sha512 implementado para encriptar la password, siendo que DB2 sólo trabaja con MD5 o SHA1, por lo tanto tienes que cambiar el algoritmo de encriptamiento de la password.

Actualización: Aquí explico como cambiar el algoritmo de encriptamiento en linux

Extraer el siguiente valor de una secuencia en DB2

Para extraer el valor actual utilicese

SELECT PREVVAL FOR [nombre_secuencia] FROM SYSIBM.SYSDUMMY1

Para obtener el siguiente valor

SELECT NEXTVAL FOR [nombre_secuencia] FROM SYSIBM.SYSDUMMY1

vsftpd 226 Transfer done (but failed to open directory).

En CEntOS se dió la causalidad de que aun cuando un usuario tiene los permisos y asignaciones hacia una carpeta, este podía entrar pero sin listar los archivos ni carpetas. Esto sucede si SELinux esta configurado, por lo que o recurres a

setenforce 0

O configuras para siempre que este modo no actué

vi /etc/selinux/config

Y estableces

SELINUX=disabled

Alternativa de Firebug en Internet Explorer

Una alternativa a Firebug que funciona de forma similar a las funcionalidades de este es el Internet Explorer Developer Tools. Funciona de forma similar a firebug, siendo esta la característica que más utilizo de ellas (un pequeño screenshot)
