[Wordpress] uploading large wxr

I have a 20mb wxr file and I split it into 10parts each file is 2mb file size. I've uploaded about 7 parts and when I upload my 8th part I get a error saying "Fatal error: Maximum execution time of 30 seconds exceeded in /home/wonderfu/public_html/omganime.info/wp-includes/wp-db.php on line 635" what's the problem??

 

I belive this is a php setting, are you on a shared host or on a dedicated server? You need to speak to your host and have this upped to say 120 seconds so that you can install the file and then change it back....failing that you need to have the last *slice* redone into a smaller file...

 

I'm on a shared host and I tried asking my host to temporarily change it but they won't do it =[. Is there a alternatively way?

 

I would go back to the source of where you got the database from and ask them to redo the slices...
