I want to say thank you Sir, but I don't know if I could ever thank you enough for the language you give to people including me especially. Am an Oracle student but whatever I don't understand in class your lecture quickly breaks it down for me to understand quicker than I thought. This is the best thing to give to the society and it's for free. Thank you so very much Sir, I am grateful for the language and your good heart, many God give you long life and bless you in abundance.

Thanks for uploading this, I currently have a system that pulls up a menu the main menu in GUI the next time you enter that menu it is completely different an old reverted menu. Obviously the issue is the first group keeps failing and switching to second group. Thinking that may be turning inactive due to misprogramming
on start as we had this happen when an archive was used to update our system and broke it.

[sribalaje]

Excellent 👍 I have a query . During alter database open resetlogs, what i understood is all redo logs gets flushed & assigned with new sequence no. But in many articles, i saw redologs gets written to archived logs.. can't understand why redo has to write it to archive logs when resetting logs for incomplete recovery. please clarify

[Saikiran-yjmt]

sir, thanks for the video and the explanation is good. In the video you have mentioned for every database needs to maintain more than 2 redo log groups and for each group it should have minimum 2 redo log members for log switch purpose.
my doubt is how many redo log groups and redo log members are supported by the database?

[StasClick]

Hi. Is that groups and members are persistent? Could members be on different machines? If it is only in memory, for me members looks like duplication of data that won't lead to optimization.
