Thread:Project:Support desk/Updating without Updating * from namespace fields in links tables./reply (2)

You shouldn't change any core files, if you don't know, what you do :) More information about that.

Depending on the size of your wiki, the update process can take a long time. For this, you can use the maintenance script, but, if you want, you can wait until the pages have self updated (on every edit), which will create the necessary values to the table. So the maintenance script is optionally, not a single function ;)

So your options:

-> use the maintenance script, to populate the fields -> wait until the fields will create themself

Note: If you aren't very familar in running a wiki or won't have much of overhead (short update cycles, possible untested scenarios wih third party extensions and so on), you should use the official thid party releases of MediaWiki instead of he wmf-builds, which are used on wmf wikis :)
