Re: [otrs] ArticleStorageSwitch.pl Out of memory

- do you know another tool to optimise the database ?

you could use the mysql command line client to connect to the DB and execute the following: OPTIMIZE TABLE otrs.article_attachment, otrs.article_plain;

- how can execute the process in steps ? the first time the process doesn't finish correct.

I was just guessing that you perhaps could start the script a second time and it would continue with the missing stuff. As my database was updated with the first run, this wasn´t necessary for me and so I don´t know if it possible at all =)
