Re: [xwiki-users] Migrate to Mysql
I tried opening the file as zip and yes, it is broken. I also tried importing the database script file but it just seems to die after a w while, I must be doing it wrong: mysql -u xwiki -p xwiki xwiki_db.sql Enter password: * ERROR 2006 (HY000) at line 1: MySQL server has gone away The export tool dies at 6mb and in the log the following is recorded: 2010-01-11 08:47:51,935 [http://dbaierxpa:8080/xwiki/bin/export/XWiki/Export?editor=globaladminsection=Export] INFO .AbstractXWikiMigrationManager - No storage migration required since current version is [15429] 2010-01-11 08:48:08,326 [http://dbaierxpa:8080/xwiki/bin/export/XWiki/Export?editor=globaladminsection=Export] WARN web.XWikiAction - Uncaught exception: Error number 0 in 11: Uncaught exception Wrapped Exception: Java heap space com.xpn.xwiki.XWikiException: Error number 0 in 11: Uncaught exception Wrapped Exception: Java heap space at com.xpn.xwiki.web.XWikiAction.execute(XWikiAction.java:238) at com.xpn.xwiki.web.XWikiAction.execute(XWikiAction.java:115) ...
