- Using the undo tablespace rather than the backup segment is recommended due to its many advantages. Do you have any evidence to support your claims?There are many justifications that support the use of the undo tablespace as opposed to the backup segment. Do you have any proof to back up the allegation that you made?What methods do you use for identifying flat and sharp major keys from their key signatures?
- What role do procedures like permutation and substitution have in encryption? Give a detailed explanation in no more than five (5) lines of text.Q4. Describe the procedure discussed in class regarding how to determine an equivalent serial schedule of a schedule with locks, if the schedule is allowed to finish under 2PL.Can ϕ(n) be part of a public key? If 10 entities need to communicate with each other, how many public keys and how many private keys are needed?
- So, what are these "triggers," exactly? But what roles do they play, exactly? With Access 2016, how can you mimic a trigger's actions?Gathering and using undo statistics is done with the goal of making the most efficient use of the undo tablespace. Is there any information that can be gleaned by undoing tablespaces? Who has access to the statistics of the undo tablespace is not made explicit. With Oracle 11g, you'll be confined to very few rules.We tell people and tell people not to use words from the dictionary as password, but they just don't listen . . . Can you find this one word, three-letter, bad password? By the way, this challenge is not really meant for you to manually guess!
