In general this error is caused by the fact that the HVR capture still needs a old archived REDO file, but that file is already removed by e.g. RMAN.
This can happen when the capture job is suspended for some time or is failing for some reason.
The options to resolve are:
– restore the old archived REDO file from backup
– reinitialize the HVR capture job to a more recent time for which the archived REDO’s are still available (using HVR Initialize “Capture Rewind” option). The missed changes can be recovered using an HVR Refresh in Online Mode
