Figure 9-1 State of the system after an INSERT There are some cached, modified undo blocks, index blocks, and table data blocks Each of these blocks is protected by entries in the redo log buffer Hypothetical Scenario: The System Crashes Right Now Everything is OK The SGA is wiped out, but we don t need anything that was in the SGA It will be as if this transaction never happened when we restart None of the blocks with changes got flushed to disk, and none of the redo got flushed to disk We have no need of any of this undo or redo to recover from an instance failure Hypothetical Scenario: The Buffer Cache Fills Up Right Now The situation is such that DBWR must make room and our modified blocks are to be flushed from the cache. This raises several interesting questions. Can we observe this Can we see this actually happen And if so, so what What does this mean to us as developers We ll address these questions in turn now. javascript qr code scanner New QR Code Reader Library - DZone Mobile

16 Feb 2018 ... The ZXing (“zebra crossing”) is an open-source, multi-format 1D/2D barcode image processing library implemented in Java , with ports to other languages. When you run the one_script.sql script, its four constituent scripts will run one after the other. This is an efficient way to execute scripts, especially when you re creating and populating a new database, provided you have already tested the individual scripts. You can also use the @@commandfile notation, as in @@one_script.sql, to run command files that include several command files. The use of the @@ notation ensures that Oracle looks for the individual files in the same path as the command file. In this case, DBWR will start by asking LGWR to flush the redo entries that protect these database blocks Before DBWR can write any of the blocks that are changed to disk, LGWR must flush the redo information related to these blocks This makes sense: if we were to flush the modified blocks for table T without flushing the redo entries associated with the undo blocks, and the system failed, we would have a modified table T block with no undo information associated with it We need to flush the redo log buffers before writing these blocks out so that we can redo all of the changes necessary to get the SGA back into the state it is in right now, so that a rollback can take place This second scenario shows some of the foresight that has gone into all of this. qr code reader java download Android Studio Tutorial - Scan QR Code by Camera - YouTube
