Change subject: core: Can remove proxy for host but left entry at DB (#844306) ...................................................................... core: Can remove proxy for host but left entry at DB (#844306) https://bugzilla.redhat.com/844306 The problem described at bug is very rare and very difficult for reproduce but , it can cause for serous trouble at engine side The problem is following: 1. We are removing host 2. The removing of host and removing its proxy done inside same transaction 3. Transaction was rollbacked due to some error 4. Entry at dabase left, proxy was removed Result: we have an orphan entry of host at DB which we can not remove, activate , etc. Our process can try to choose that entry as SPM or try to activate via Auto recovery, it is obvious that we will not success. Solution: Diasable global transaction, perform removefrom DB at separete transaction if it fails, the proxy will left, if it success the proxy will be removed.
