RECOVER DATABASE UNTIL AVAILABLE; RMAN-00571: =========================================================== RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS =============== RMAN-00571: =========================================================== RMAN-00558: error encountered while parsing input commands RMAN-01009: syntax error: found ";": expecting one of: "redo" RMAN-01007: at line 1 column 33 file: standard input RMAN> RECOVER DATABASE NOREDO; Starting recover at 16.01.2022 16:50:40 using channel ORA_DISK_1 Finished recover at 16.01.2022 16:50:40 So C must be incorrect. B - ok

Selected Answer: C

B is FALSE, as it causes no archive logs to be applied. This is meant for a database that is running in NOARCHIVELOG. C: RECOVER DATABASE UNTIL AVAILABLE REDO ; Finds the last available archived redo log and online redo logs, and recovers the database to the point where a log is missing. The database files still needs to be consistent enough to open the database.

B The NOREDO options is required if redo logs are not available. If you do not specify NOREDO when recovering a NOARCHIVELOG database, then RMAN ends recovery and issues an error.

This question is wrong. Is missing the word "REDO" on item 7. If you try a RECOVER DATABASE NOREDO and try to open the database with RESETLOGS option you get: ORA-01139: RESETLOGS option only valid after an incomplete database recovery If you try a RECOVER DATABASE NOREDO and try to open the database with RESETLOGS option you get: ORA-01113: file 1 needs media recovery. So NOREDO is not an option here. The right answer is C if item 7 is RECOVER DATABASE UNTIL AVAILABLE REDO". Otherwise there's no correct answer for this question.

I think B is the correct because of the "minimum required steps" restriction. (The C sames to be also correct, but in this case one aditional step to reapplying the redo entries will be made also)

Just one another remark. The correct syntax should be "UNTIL AVAILABLE REDO" and not "UNTIL AVAILABLE". So C must be incorrect.

F is the correct answer. Recover database until available is a new feature of 19c. https://web.stanford.edu/dept/itss/docs/oracle/10gR2/backup.102/b14191/recoscen008.htm#i1006564
