Hi Gerardo, Thnq for responding.
My doubt is , if I apply online logs , will it cause index corruptions. (ora - 600 error). In my last refresh , I applied online redo log. I got the message when I apply this log is Media recovery completed. After that I opened the db with resetlogs. Everything went fine. But later when the team is working that some indexes got corrupted and returning ora-600 errors. But in production db they are ok. Can you explain why this happened.?

(test1 from prod1 db) I took the hotbackup files and online redo logs. I created the controlfile using these files. After that I performed recovery. Here I applied online logs instead of archive logs. (There are 7 grous of online redo logs each contains 3 members). When I tried to open the db, it asked that datafile needs recovery. I applied online redo log instead of archive log. The next day I observed that indexes got corrupted (This msg is from another dba group who are working with this new test database) My doubt is : applying online redo logs instead of archive logs lead to this index corruption? can anybody come across such any situation. Now I need to do refresh again in another way applying archive logs.
