Basic concepts of Data link layer three basic issuesPackage into frame: Before and after a piece of data with the first and the tail, and then constitute the frame, the role of the first and the end is to define the frame;Transparent transfer: When the transmitted data contains headers and trailing characters, it needs to be escaped (resolved with a byte fill, and the escape character is filled in front of the special characters in the data);Error control: The transmission process may produce bi

other parameters of the settings. To set the sampling rate as an example, the flow chart is as follows, Similarly, in the function Soc_pcm_hw_params, the CPUÀPLATFORMÀCODEC is still followed The approximate order.

modifies the block scn. The three are consistent. When delayed block cleanout occurs, the previous transaction commit updates only the Transaction table, but does not process the block. Wait until the next time you use this block, update the block scn and itl statuses. Block scn and itl are updated in two situations: (1) When no slot is reused (ITL is not reused) and delayed block cleanout, according to the information in the Transaction table, update the scn/

undo segment header is not overwritten, you can retrieve the exact scn submitted by the transaction. If the slot has been overwritten, the control scn In the undo segment header is used as the upper bound scn. When fast commit cleanout occurs, the system uses the scn of the transaction commit time as the commit scn, updates the scn on the Transaction table slot of the itl and undo segment headers on the block, and modifies the block scn, the three are consistent. When delayed block cleanout occ

First, ITL describes:The ITL (interested Transaction List) is an integral part of the Oracle data block, located in the block header, which consists of Xid,uba,flag,lck and SCN/FSC, Used to record all occurrences of the block, an ITL can be viewed as a transaction record. Of course, if the transaction has already been committed, then the ITL position can be reused, because ITL resembles the record, so sometimes it is called an ITL slot. If a transacti

Predef, which is placed in the package Scala, contains a number of useful methods. For example, when you write Pringln in a Scala
