The hope is that the holder of the latch is busy processing on the other CPU (and since latches are designed to be held for very short periods of time, this is likely) and will give it up soon If after spinning and constantly trying to get the latch, we still fail to obtain it, only then will our process sleep, or take itself off of the CPU, and let some other work take place This sleep action is usually the result of many sessions concurrently requesting the same latch; it is not that a single session is holding it for a long time, but rather that so many sessions want it at the same time and each hold it for a short duration If you do something short (fast) often enough, it adds up! The pseudo-code for a latch get might look like this: Loop for i in 1 .. javascript barcode scanner input zxing/zxing: ZXing ("Zebra Crossing") barcode scanning ... - GitHub

Was the shared server approach considered, for example How were the wait statistics I don t know the details I do know that the Oracle database is fully capable of meeting the requirements of an application such as this I picked this example to show that even in high-profile cases, DBAs sometimes have to eat humble pie when the database isn t tuned properly and consequently performance doesn t meet expectations.. 2000 loop try to get latch if got latch, return if i = 1 then misses=misses+1 end loop INCREMENT WAIT COUNT sleep Add WAIT TIME End loop;. This means if that UPDATE statement were to take five minutes to process from start to finish, and someone added and committed a new record to the table with a value of 5 in the Y column, then that UPDATE would not see it because the consistent read would not see it This is expected, and normal But, the question is, what happens if two sessions execute the following statements in order Update t set y = 10 where y = 5; Update t Set x = x+1 Where y = 5; Table 7-8 demonstrates the timeline.. download barcode scanner for java mobile BarCode Reader Free Java App - Download for free on PHONEKY
