| Video Discription | This video describes the best architecture of the oracle after trying more than times to Oracle structure I decided to produce an animated video let's start first with the database structure on the left side you have the client here on the right side you have to serve a two-year the server side is divided in three main structures to memory the logical structure and the physical structure so let's use SQL Plus application to provide you every step up a transaction will be using Scott sample schema it is important to note that the whole string is an alias and not a database name district will be compared to this alias inside of a file called pianist named doc or this file is similar to a DNS and with up pain all the necessary detail to reach a database server locally a user process will be allocated and will validate the connection through a listener the listener will be in charge to allocate a server process the user processes da link to the server process let's now execute our first transaction for this example we will execute an update first to state that will be validated we call this step the parsing this server process sense back to confirmation of the parsing that statement with be written into their share pool and the redo log buffer an execution plan will also be created it to the fair share Paul that database book they choose fought the transaction will be read and copy into the database buffer cache only that feel implicated in that transaction will be held it to a - segment till the transaction is completed we call those copies the before image a copy of this block will be duplicated with the updated feel this copy is called me after image a confirmation will be sent to to use a process the commit statement will complete the transaction and will be written into to redo log buffer to commit statement triggers the log writer process and we'll send all statement for the current transaction into the redo log file the before image into undo segment could be then deleted went that threshold up to undo retention parameters reach alaskan from Asian will be sent to the user process went to current law kiss Paul it generates a switch lock triggering at the same time the archiver process and to log sequence number the archiver will generate and archive the file with the content of the current loc a switch up with them trigger a checkpoint process that will incriminate the checkpoint number by applying this last number into each data file header the checkpoint process with finally trigger the database writer process enright the last image from that database buffer cache into thirty people bt8-QJr8bqA |
