We are in the process of migrating to 7.8 from 7.5 and have a 7.5 standby. Needed to test the time is takes to backup from the standby once we go-live on the 7.8 64bit server. Logs have been applied to the 7.5 standby for more than a month just fine prior to doing a "cold" backup test on the standby. Now the logs will not apply to the standby.
| ERR 20039 Log | Logrecovery is not allowed, because state of log volume is 'HistoryLost' (log must be cleared) | |

First - backing up the standby in ADMIN mode / cold backup on the standby database, right? The source and target (standby) have different server names.
Is it possible to clear the log area or some other process to fix the issue?
