Full message is:

resource [WLStore_osbpr1do_CommonFileStore1] is unavailable. The transaction will be abandoned after 84,775 seconds unless all resources acknowledge the commit decision.

Googling in Oracle Forum I find this recipe to use if the above error prevents your server from starting:

1. Stop your server.
2. Go to [your domain]\servers\AdminServer\data\store\default.
3. Delete* _WLS_ADMINSERVER_[random number].DAT
4. Restart server
