What do you want to do with the contents of the wiki afterward? If you want to migrate it to another machine, inside another mysql database, then it would be simpler to dump and import the database data directly, using mysqldump or something similar. You should only increase the -Xmx parameter, since this is the heap memory, while MaxPermSize is used only for storing classes. Try something like: -Xmx2048m -XX:MaxPermSize=128m -- Sergiu Dumitriu http://purl.org/net/sergiu/ _______________________________________________ users mailing list users@xwiki.org http://lists.xwiki.org/mailman/listinfo/users
