detected, the data is required to be retransmitted from one frame to another from the sending node. The data link error detection process is handled by the cyclic redundancy check (cyclic redundancy CHECK,CRC). Cyclic redundancy check (CRC) is an error detection method that calculates a value for the entire information field contained in the frame (SOF, addressing method, control information, data, CRC, and EOF). This value is inserted by the data link layer to the point where the sending node

The IEEE 802 committee splits the LAN's data link layer into two tiers, the Logical Link Control LLC and the media access control Mac two sub layers.

FileMaker's 9th version of software with the same na

written to the block.If a user session is experiencing an idle buffer wait event, and the wait count increases steadily, this means that there is insufficient free blocks in the SGA. This can happen if the buffer cache is too small, or if the DBWR cannot keep up with the block dirty rate. One of the reasons why the DBWR process cannot keep up with dirty blocks is that it spends too much time on parallel write events in db files.Parameters:P1 = number of files that Oracle is writing.P2 = number
