The command that you should use in conjunction with the ssh-agent bash command is: ssh-add ~/.ssh/id_dsa
What does SSH-add ~/ ssh Id_rsa do?SSH's key manager is called ssh-agent. Your keys and certificates are kept there in memory, unencrypted and available for use by ssh. You don't have to type a passphrase each time you connect to a server because of it.
Therefore, the private key password is requested from the user and added to the list kept by ssh-agent using the ssh-add command. When using SSH or scp to access to hosts with your public key, you won't be prompted for your password once you've added it to ssh-agent.

Dirty read was concurrent processing problem occurs when a transaction rereads data and finds new rows that were inserted by a different transaction.
What is Dirty read?Dirty Reads occur when a transaction is permitted to read a row that has been updated by another transaction but has not yet been committed. Multiple uncommitted transactions occurring at once are the main cause of it.Executing the aforementioned query will result in the output "Not committed" since there is a problem—there is no ID=C. Therefore, if we want to start another transaction with that row at that point, Dirty Reads will happen. No partial commitment exists if both UPDATE queries are successful, at which point the output will be "Committed."The only isolation level accessible to databases without transaction recording is dirty read.To learn more about Dirty read refer to:

a. True - PATA (Parallel ATA) hard drives are older and slower than SATA (Serial ATA) hard drives due to their use of parallel data communication technology.
b. False - SATA revision 1.x is only marginally faster than SATA revision 3.x, as the latter uses 6 Gbit/s data transfer speeds compared to the 1.5 Gbit/s of the former.
c. False - RAID 0 can indeed be implemented using only a single hard drive, as it does not involve any data redundancy.
d. False - RAID 5 requires at least three hard drives working together at the same speed and capacity.
e. False - An internal SATA data cable cannot be used with an SATA port, as they have different connectors and cable lengths.
f. True - A SATA internal data cable has seven pins, which include four data pins, two ground pins, and a 12V power pin.
What is PATA and SATA? PATA (Parallel ATA) and SATA (Serial ATA) are two different types of computer data storage cables and connectors. PATA is an older technology and is used mainly for older hard drives and optical drives. SATA is a newer technology and is used for newer hard drives and optical drives. SATA connectors and cables are faster and smaller than PATA connectors and cables, and are the current standard for connecting internal storage devices to the motherboard.PATA cables connect to the motherboard using a 40-pin connector. The data is transferred in 16-bit parallel form, meaning that data is sent in 16 parallel wires. This type of data transfer is not very efficient, which is why SATA is taking over.SATA cables connect to the motherboard using a 7-pin connector. The data is transferred in 8-bit serial form, meaning that data is sent in one single wire. This type of data transfer is much more efficient and allows for faster data transfer rates.Both PATA and SATA cables can be used to connect storage devices to the motherboard. However, SATA is becoming the preferred connection due to its higher data transfer rates and smaller size. PATA is slowly becoming obsolete.To learn more about PATA & SATA refer to:
