Re: Academic question: How to recover through a gap of archived redol ogs with data loss?

- Do a tablespace point in time recovery using all the archives starting from the backup till the last continuous one that you have.
- Use logminer to mine the relevant data from the archives after the gap. Pray that there aren't too many data consistency issues.
