If you have a fresh install of OEL 4.
If you have installed the Oracle grid control agent.
If you have allready executed « root.sh » script but you’re sticked with an « NMO not setuid-root » error while cloning Oracle Home or anything else.
Then you have to set correct ownership to some files :

$ chown root $ORACLE_HOME/bin/nmo
$ chmod 6750 $ORACLE_HOME/bin/nmo
$ chown root $ORACLE_HOME/bin/nmb
$ chmod 6750 $ORACLE_HOME/bin/nmb

now « Try Again »!

Here is a PL/SQL package that I’ve made to check and convert Belgian’s BBANs and IBANs codes whitin SQL queries.

package : BBAN_IBAN_BIC.sql (160)
package body : BBAN_IBAN_BIC_Body.sql (160)

You’ll need a table of BICs codes to get the BIC code out of BBAN and IBAN.

Download an updated version from :
http://www.bnb.be/ « Systèmes de paiement »> »Standards de paiements »> »Codes d’identification des banques »

or you could use directly this one (at youre own risk) : BIC_Table.sql (255)

Here the way I follow to install and make work Google Earth on Fedora 11 x86-64:

First download the linux version of Google Earth at : http://earth.google.fr/

open a terminal and become root:

su -
yum install google*

with an nvidia card you’ll need:

yum install xorg-x11-drv-nvidia-libs*.i586 (search with software install gui if it doesn't work)

and for ati card (thanks to space-hunter):

yum install xorg-x11-drv-catalyst-libs.i586

you’ll need these 32 bit libraries for Google to run quietly

yum install glibc-2.10.1-2.i686 libxml2.i586 freetype.i586 libXrender.i586 libXrandr.i586 mesa-libGL.i586 xorg-x11-drv-nvidia-libs.i586

Additions from Otto Mäkelä :

yum install libcanberra-gtk2.i586 bug-buddy.i586 PackageKit-gtk-module.i586

Then run :

sh GoogleEarthLinux.bin

it’s all…

here is for the cron tab:

00 22 * * * /opt/oracle/admin/acisora1/scripts/export_backup.sh >> /dev/null

the script will be executed avery at 10 pm

1) install apache, php …

yum install httpd php php-mysql php-pear php-devel zlib zlib-devel
yum groupinstall « Development Tools »

2) Download and install oracle instant client (basic and devel) from there:

http://www.oracle.com/technology/software/tech/oci/instantclient/htdocs/linuxsoft.html

rpm -Uvh oracle-instantclient-basic-<VERSION>.i386.rpm
rpm -Uvh oracle-instantclient-devel-<VERSION>.i386.rpm

3) Add the Oracle instant client to dynamic linker

echo /usr/include/oracle/<VERSION>/client/lib/ > /etc/ld.so.conf.d/oracle_client.conf
ldconfig -v

4) Untar the PECL package and prepare it for compiling

tar -xzvf oci-<VERSION>.tgz
cd oci-<VERSION>
phpize

5) Configure the PECL package as a shared object using the instant client and specifying where the Oracle client libraries are. Then build and install it.

./configure –with-oci8=shared,instantclient,/usr/lib/oracle/<VERSION>/client/lib
make
make install

6) Add the library shared object for PHP

echo extension=oci8.so > /etc/php.d/oci8.ini

7) Start Apache

’service httpd start’ _or_ ‘/etc/init.d/httpd restart’

Create a PHP info page and checked to see if the Oracle (oci8) driver is listed:

echo <? phpinfo(); ?> > /var/www/html/phpinfo.php

Here is a trick that I’ve used in the intranet of my company that have an insane use of rdp protocol avor slow internet connections.

The problem was that scrolling down in web pages containing some images was incredibly slow in firefox. That was due to the redraw of image while scrolling so I’ve decided to find a trick to hide some parts of the page during the time of scrolling.

After adding the javascript code to your page, just add the class « scrollhide » to objects that you want hide when scrolling.

exemple of use:

<div class= »scrollhide »>text to hide while scrolling</div>

<img src= »./img/imagetohide » class= »scrollhide »/>

You could easily use it to what ever you want during the onscroll event.

!!! Tested with firefox 3 and IE 7 !!!

var curdate = new Date()
var lastOnscroll = curdate.getTime();

function getElementsByClass(searchClass,node,tag) {
    var classElements = new Array();
    if ( node == null )
        node = document;
    if ( tag == null )
        tag = '*';
    var els = node.getElementsByTagName(tag);
    var elsLen = els.length;
    var pattern = new RegExp("(^|\\s)"+searchClass+"(\\s|$)");
    for (i = 0, j = 0; i < elsLen; i++) {
        if ( pattern.test(els[i].className) ) {
            classElements[j] = els[i];
            j++;
        }
    }
    return classElements;
}

function timeHideBanner() {

    var newcurdate = new Date()
    if ((newcurdate.getTime() - lastOnscroll) > 200  ) {
        var myEls = getElementsByClass('scrollhide');
        for ( i=0;i<myEls.length;i++ ) {
        // do stuff here with myEls[i]
            myEls[i].style.visibility = 'visible';
        }
        //document.getElementById('banner').style.visibility = 'visible';
    }
}

function hideBanner() {
    var newcurdate = new Date()
    lastOnscroll = newcurdate.getTime();

    var myEls = getElementsByClass('scrollhide');
    for ( i=0;i<myEls.length;i++ ) {
    // do stuff here with myEls[i]
        myEls[i].style.visibility = 'hidden';
    }
    //document.getElementById('banner').style.visibility = 'hidden';
    var t=setTimeout("timeHideBanner()",300);
}

window.onscroll = function(){ hideBanner(); }

window.mouseup = function(){ document.getElementById('banner').style.visibility = 'visible'; }

Here is a little app to convert a pdf to multiple images in pdf format.

Just open pdf and then save selected page or all pages in a png file.

Dowload : Pdf2Img (105)

Functions gived here comes initially from developpez.com but has been modified to convert numbers in the belgian way (septante,nonante) then I’ve added possibility to add devise like Euro.

Here comes downloadable files:
english numbers to words function(needed) : to_word_en (113)
belgian translation : translate_be (265)

examples:

Here is a way to add the group_concat function to ORACLE. After that you’ll be able to do just like in MySQL.

first you’ll need to create a new object type:


create or replace TYPE t_string_agg AS OBJECT
(
g_string VARCHAR2(32767),

MEMBER FUNCTION ODCIAggregateMerge(self IN OUT t_string_agg,
ctx2 IN t_string_agg)
RETURN NUMBER
);


then create a function using the newly created type :


create or replace FUNCTION tring_concat (p_input VARCHAR2)
RETURN VARCHAR2
PARALLEL_ENABLE AGGREGATE USING t_string_agg;


now try it with SCOTT’s schema


COLUMN employees FORMAT A50

3 rows selected.


that could be quite useful to add this function to the SYS schema and then create a public synonym. this way the function will be available to any user of the database.
