Normally upgrading from Magento 1.0.19870 to 1.3.1 should be no problem, as Magento takes care of all the required table changes.  I mostly faced script timeouts on the server in the past, which broke the upgrade process and turned the installation unusable.

I have switched to upgrading customer databases on a local installation, as that allows me to workaround timeouts and prepare databases for the upgrade.

Before upgrading an installation, you should also delete any content that can be recreated by Magento again. Logs, price rule caches …. can all be deleted, as the system can generate those again.

Really sad how everyone needs to piece those things together, as the Magento Community Knowledge Base is mostly outdated and many hints are buried deep inside the forums.

Currently working my way through a huge Magento 1.0.19870 database and will comment on my success once everything works.

Once you have done the export / import multiple times, it gets really easy :)

Here are some things that made things alot easier for me

  1. Update magento/app/etc/local.xml with your changed database details
  2. Update the secure / unsecure urls to match your new domain / setup
    These settings are saved in the magento_core_config_data table.
    The two settings you need to alter are
    – web/unsecure/base_url
    – web/secure/base_url
  3. Sometimes the foreign key constraints break tables on import. The most common are :
    – magento_customer_group
    – magento_core_website
    – magento_core_store
    – magento_core_store_group

    Just check your old setup and update those tables by hand.

    You can run queries by activating and deactivating the foreign key check like this:

    SET FOREIGN_KEY_CHECKS=0;

    INSERT INTO magento_core_website (website_id, code, name, sort_order, default_group_id, is_default) VALUES
    (0, ‘admin’, ‘Admin’, 0, 0, 0),
    (1, ‘base’, ‘Main Website’, 0, 1, 1);

    SET FOREIGN_KEY_CHECKS=1; 

  4. Make sure to delete the following folders before you try to access the install again
    – var/cache
    – var/sessions

When it comes to permissions Magento Commerce is very picky, especially as pear requires full write permissions.

The following permissions should be used during install:
find . -type d -exec chmod 777 {} ;
find . -type f -exec chmod 777 {} ;

This will reset all permissions after you are done and secure your setup again:
find . -type f -exec chmod 644 {} ;
find . -type d -exec chmod 755 {} ;
chmod o+w var var/.htaccess app/etc
chmod 550 pear
chmod -R o+w media

nikon1Nachdem ich schon einige Kameras für mimmaTEC TV testen konnte, war für mich eigentlich klar, dass es eine Nikon sein sollte. Sie schien die bedienerfreundlichste Kamera für mich als SLR- Wiedereinsteiger zu sein. Auch mit wenig Kenntnis über Belichtung, Verschlusszeiten und Blende bot sie die besten Ergebnisse. Ich muss gestehen, dass ich auch heute noch gern die Kamera entscheiden lasse, welche Einstellungen in gewissen Situationen die Richtigen sind.

Allerdings arbeite ich daran, diese Tatsache zu ändern. Galileo Design hat uns einige Bücher über digitale Fotografie zur Verfügung gestellt, mit deren Hilfe ich mein Wissen über Motivgestaltung, Nahaufnahmen, Naturaufnahmen und vieles mehr erweitern möchte. Auf diese Bücher werde ich noch genauer eingehen.

Ursprünglich wollte ich mir eine Nikon D80 kaufen, auf der CeBIT ‘09 hatte ich dann, mehr durch Zufall, die Nikon D90 in der Hand. Und ich hatte Blut geleckt!! Vor allem, weil diese Kamera auch noch HD Videos aufnehmen kann – wer hätte das gedacht!Langer Rede kurzer Sinn: Es wurde nach vielem recherchieren im Internet und hin und her doch eine Nikon D90 mit einem AF-S DX Nikkor3,5-5,6/18-105 mm G ED VR Objektiv.

Wenn ich ehrlich bin, war ich im ersten Moment fast ein wenig überfordert mit den ganzen Funktionen und Einstellungen, die diese Kamera zu bieten hat. Aber meine Devise ist „learning by doing“ und so kann es nur besser werden…

Komodo Development IDE

When it comes to my development environment I have always been really picky. I need a clean and structured interface, not to cluttered, but still adjustable to my needs. I have tested countless IDE solutions in the past, but always seem to come back to Komodo from ActiveState.

“MetaNote intends to be the most versatile editor imaginable. Right
click on features in the editor and edit the code behind them. Don’t
like the way ‘Find’ works? — right click on it, and edit the code.
Need a new button in the toolbar? So add it already, with a single
click. Share packs of extensions and macros with other users.
Everything in MetaNote is under your control, effortlessly, at runtime.”

The project is still in its alpha stages, but a really unique approach. The developer is looking for people that like to jump in and help out making it as versatile as possible.

MySQLDumper is a backup programm for MySQL-Databases, written in PHP and Perl. You can dump your data into a backup file
and if needed, restore it. Especially on shared hostings without access to shell-commands, MySQLDumper is a sensefull
option.

MySQLDumper uses a proprietary technique to avoid execution
interruption. It only reads and saves a certain amount of commands and
then calls itself via JavaScript and memorizes how far in the process
it was and resumes its action from its last standby.

MySQLDumper restores a backup file by using the same process. Unlike
other tools splitting and splicing of large files is no longer
necessary.
