So far, we ve seen how multi-versioning provides us with non-blocking reads, and I have stressed that this is a good thing: consistent (correct) answers with a high degree of concurrency. What could be wrong with that Well, unless you understand that it exists and what it implies, then you are probably doing some of your transactions incorrectly. Recall from 1 the scheduling resources example whereby we had to employ some manual locking techniques (via SELECT FOR UPDATE to serialize modifications to the SCHEDULES table by resource). But can it affect us in other ways The answer to that is definitely yes. We ll go into the specifics in the sections that follow. how to get input from barcode reader in java Free Barcode Reader and Scanner Software | Free to Scan Linear ...

I have an idea, borne out by first-hand personal experience (meaning I made the mistake myself), as to why database-backed software development efforts so frequently fail. Let me be clear that I m including here those projects that may not be documented as failures, but nevertheless take much longer to roll out and deploy than originally planned because of the need to perform a major rewrite, re-architecture, or tuning effort. Personally, I call such delayed projects failures: more often than not they could have been completed on schedule (or even faster). The single most common reason for failure is a lack of practical knowledge of the database a basic lack of understanding of the fundamental tool that is being used. The black box approach involves a conscious decision to protect the developers from the database. They are actually encouraged not to learn anything about it! In many cases, they are prevented from exploiting it. The reasons for this approach appear to be FUD-related (Fear, Uncertainty, and Doubt). Developers have heard that databases are hard, that SQL, transactions, and data integrity are hard. The solution don t make anyone do anything hard. They treat the database as a black box and have some software tool generate all of the code. They try to insulate themselves with many layers of protection so that they don t have to touch this hard database. java code 39 generator, ean 128 excel macro, java ean 13, qr code in c# windows application, pdf to tiff c# code, excel code 39 font zxing barcode scanner javascript [Solved] barcode reader in java - CodeProject

Above all, try not to confuse the symptoms of poor performance with the causes of poor performance If your latch rate is high, you might want to adjust some initialization parameters right away after all, isn t Oracle a highly configurable database You may succeed sometimes by relying solely on adjusting the initialization parameters, but it may be time to pause and question why exactly the latch rate is so high More than likely, the high latch rate is due to application coding issues rather than a specific parameter setting Similarly, you may notice that your system is CPU bound, but the reason may not be slow or inadequate CPU resources Your application may again be the real culprit because it s doing too many unnecessary I/Os, even if they re mostly from the database buffer cache and not disk. zxing barcode reader java example Topic: barcode-scanner · GitHub

A common data warehousing technique I ve seen people employ goes like this: 1. They use a trigger to maintain a LAST_UPDATED column in the source table, much like the method described in the last chapter, in the Optimistic Locking section. 2. To initially populate a data warehouse table, they remember what time it is right now by selecting out SYSDATE on the source system. For example, suppose it is exactly 9:00 am right now. When you re examining wait ratios, understand that your goal isn t to make all the wait events go away, because that will never happen Learn to ignore the unimportant, routine, and unavoidable wait events As you saw in the previous section, wait events such as the SQL*Net message from client event reflect waits outside the database, so don t attribute these waits to a poorly performing database Focus on the total wait time rather than the number of wait events that show up in your performance tables and AWR reports Also, if the wait events make up only a small portion of response time, there s no point in fretting about them As Einstein might say, the significance of wait events is relative relative to the total response time and relative to the total CPU execution time. java barcode reader api Building HTML5 Barcode Reader with Pure JavaScript SDK ...
