There are blocks in v$nonlogged_block, but NONLOGGED_START_TIME is empty

in Database Administration (MOSC) 3 commentsAnswered

  • There are records in v$nonlogged_block, but NONLOGGED_START_TIME is empty. Why is it? How can I find out when the were the blocks "corrupted"?
  • It tried to convert to SCN number in NONLOGGED_START_CHANGE# with SCN_to_timestamp() but it did not work. It was working with the SCN number until ca last week. It think the SCN number than in NONLOGGED_START_CHANGE# and so the corrupt blocks are older then a week. Or?

Howdy, Stranger!
