I'm trying to delete a feature class from a personal geodatabase using ArcCatalog but the file is locked because it's opened exclusively by me. The process fails to get a schema lock. Well of course it is, I'm trying to edit the PGDB. How do you delete a feature class without opening the PGDB in ArcCatalog?

Edit: To make it clear, the PGDB is ONLY open in ArcCatalog. I even rebooted to make sure there was no residual locking.

    File and personal geodatabases aren't really meant to be operated on over a network, and people have had a host of locking issues when doing so. It could be an Arc process and some sort of time delay lag introduced because of the network, or it could be a completely unrelated process such as a virus scanner. After reboot, before starting Arc anything, check the network folder for a lock file and delete if present - they don't always go away like they should. Failing that either introduce delay between steps (such as waiting for preview regen), or copy the mdb locally, edit, and copy back. – Chris W Jul 2 '15 at 19:13

Try right clicking on the feature class then clicking on manage, then locks, and try disconnecting the user.

  • Locks isn't one of the options in the Manage menu. Must be a different version. I'm on 10.3.1. There are several greyed out entries and the usable ones are: Add Global Ids and Create Attachments – KMWPJPL Jul 2 '15 at 19:15

    The manage item is only available for an enterprise geodatabase – Rich Wawrzonek Jul 2 '15 at 23:03
