The log buffer is a small, short-term staging area for change vectors before they are written to the redo log on disk A change vector is a modification applied to something; executing DML statements generates change vectors applied to data The redo log is the database s guarantee that data will never be lost: whenever a data block is changed, the change vectors applied to the block are written out to the redo log, from where they can be extracted and applied to datafile backups if it is ever necessary to restore a datafile Redo is not written directly to the redo log files by session server processes If it were, the sessions would have to wait for disk I/O operations to complete whenever they executed a DML statement Instead, sessions write redo to the log buffer, in memory This is much faster than writing to disk The log buffer (which may contain change vectors from many sessions, interleaved with each other) is then written out to the redo log files One write of the log buffer to disk may therefore be a batch of many change vectors from many transactions Even so, the change vectors in the log buffer are written to disk in very nearly real time and when a session issues a COMMIT statement, the log buffer write really does happen in real time The writes are done by the log writer background process, the LGWR The log buffer is small (in comparison with other memory structures) because it is a very short-term storage area Change vectors are inserted into it and are streamed c# upc-a reader C# UPC-A Barcode Scanner Library - Read & Scan UPC-A Using ...

Size setting of C# UPC-A Generator- Using C# to Set Barcode Width, Barcode Height, X, Y, Image Margins. to disk in near real time There is no need for it to be more than a few megabytes at the most, and indeed making it much bigger than the default value can be seriously bad for performance The default is determined by the Oracle server and is based on the number of CPUs on the server node It is not possible to create a log buffer smaller than the default If you attempt to, it will be set to the default size anyway It is possible to create a log buffer larger than the default, but this is often not a good idea The problem is that when a COMMIT statement is issued, part of the commit processing involves writing the contents of the log buffer to the redo log files on disk This write occurs in real time, and while it is in progress, the session that issued the COMMIT will hang Commit processing is a critical part of the Oracle architecture The guarantee that a committed transaction will never be lost is based on this: the commit-complete message is not returned to the session until the data blocks in the cache have been changed (which means that the transaction has been completed) and the change vectors have been written to the redo log on disk (and therefore the transaction could be recovered if necessary) A large log buffer means that potentially there is more to write when a COMMIT is issued, and therefore it may take a longer time before the commitcomplete message can be sent, and the session can resume work Raising the log buffer size above the default may be necessary for some applications, but as a rule start tuning with the log buffer on default The log buffer is allocated at instance startup, and it can never be resized subsequently without restarting the instance It is a circular buffer As server processes write change vectors to it, the current write address moves around The log writer process writes the vectors out in batches, and as it does so, the space they occupied becomes available and can be overwritten by more change vectors It is possible that at times of peak activity, change vectors will be generated faster than the log writer process can write them out If this happens, all DML activity will cease (for a few milliseconds) while the log writer clears the buffer The process of flushing the log buffer to disk is one of the ultimate bottlenecks in the Oracle architecture You cannot do DML faster than the LGWR can flush the change vectors to the online redo log files If redo generation is the limiting factor in a database s performance, the only option is to go to RAC In a RAC database, each instance has its own log buffer, and its own LGWRThis is the only way to parallelize writing redo data to disk. c# upc-a reader UPC-A C# DLL - Create UPC-A barcodes in C# with valid data
