A client has been unable to fix corruption of system files and does not have a backup or an Automated System Recovery (ASR) disk. Which of the following is the BEST action to take next?()
You have the following requirements in relation to the detection of block corruption for your database instance: 1. Check for logical self-consistency of data blocks when modified in memory. 2. Checksums are calculated before and after the block change. 3. Checks are performed for the lost writes to the physical standby database. Which method would help you perform the above checks automatically? ()
Because of a logical corruption in your production database, you wanted to perform Tablespace Point in Time Recovery (TSPITR). But before you start the recovery, you queried the TS_PITR_OBJECTS_TO_BE_DROPPED view and realized that there are a large number of objects that would be dropped when you start the recovery by using this method.You want to preserve these objects. Which option must you use to perform TSPITR and preserve the object?()
