Eno's questions

I'm having an issue, I searched a lot but I'm not sure if it's related to a previous security patch. On the last version of MySQL on Debian Lenny ( 5.0.51a-24 ) I need to share one table between two db, those two db are in the same path ( /var/lib/mysql/db1 & db2 ). I created symbolic links for db2 pointing to the table in db1.

When I query the same table from db2 I get this : 'ERROR 1030 (HY000): Got error 140 from storage engine'

This is how it looks :

test-lan:/var/lib/mysql/test3# ls -alh
drwx------ 2 mysql mysql 4.0K 2010-08-30 13:28 .
drwxr-xr-x 6 mysql mysql 4.0K 2010-08-30 13:29 ..
lrwxrwxrwx 1 mysql mysql 28 2010-08-30 13:28 blbl.frm -> /var/lib/mysql/test/blbl.frm
lrwxrwxrwx 1 mysql mysql 28 2010-08-30 13:28 blbl.MYD -> /var/lib/mysql/test/blbl.MYD
lrwxrwxrwx 1 mysql mysql 28 2010-08-30 13:28 blbl.MYI -> /var/lib/mysql/test/blbl.MYI
-rw-rw---- 1 mysql mysql 65 2010-08-30 13:24 db.opt 

I really need those symlinks, is there a way to make them working like before ? ( old MySQL-server is fine )

After an update of our website ( running on Apache ) we get some issues with .js files images ect ... It seems that old files were mixed up with new one. My question is how cache works ? Do we have to restart Apache each times we perform an update ? How Firefox know / handle new files from a website ? Thanks!

Hello I've a question because i'm not sure about something. When I perform whois on domain.com I get something like :

Domain servers in listed order :
ns1.domain.com
ns2.domain.com

The IP from ns1.domain.com is 'hard coded' in the registrar. My question is when I do a host on ns1.domain.com, I retrieve the IP from registrar or from my DNS server ?

Thanks, I hope it's not too confused.
