Gap is created by the fact that the archive log between the repository and the main repository may be inconsistent due to network and other reasons between the Dataguard master and standby.Steps to resolve gap:1. Get gap details in the standby library2. Copy the required archive logs from the main library to the standby library3. The Standby library registers the

Because the company project needs to study webservice long-standing, WebService's efficiency problem has been a headache. n just before, I studied the dynamic reflection form of dynamic shape webservice, but also large-scale application in the project, Zennai efficiency is low to a certain extent. The specific code I also posted out, that is, the popular online dynamic call method 　　　　 Dynamic is my dynamic, but unfortunately the efficiency is too bad, today really feel not, on the test of

runs on a U disk, such as the U disk disguised as a solid-state drive. But once the U disk as a solid-state drive as a system disk to use, there is the biggest problem, that is read marry write speed too slow! This is mainly because of the USB disk and solid state drive between the master chip, the number of flash particles and cache capacity caused by different. In particular, the solid-state hard disk uses a number of flash particles, and its internal is similar to the use of RAID writing, ca

for DDR4 and DDR3 memory, a lot of computer players want to know the DDR4 and DDR3 which is good? Which is worth buying? The following is a test of DDR3 2400MHz memory and DDR4 2400MHz memory, their performance gap is how big. Must the new be stronger than the old ? Memory testing is more boring, at present in the major hardware, the frequency of memory is often the most easily overlooked, but is the capacity of memory, more than the freq

This paper demonstrates the method of C language to realize the maximum gap problem, which has some reference value for the design of the algorithm. Share to everyone for your reference. Specifically as follows: The problem is described as follows: Given n real x1,x2,..., xn, it is required to design a linear time algorithm to find the maximum difference between the 2 numbers of n real numbers on axes. Solution Idea: The design of linear time algo

is still the row layout after the trigger. So the block element is presented as an inline object, and Display:inline plays this role (* is identified only by IE6, 7), and then triggers layout through zoom:1. Can realize the so-called inline-block. But things are far from over, this guy faces a number of funeral needs you to deal with, for example, will default to have the outside margin (IE6, 7 except). And before this problem, you may need to relax and look at the following phenomenon. As me

After reading the test results of the PCMark05 software, we will compare the performance of the Vista operating system and Windows XP operating system on the three main components of the video card, processor, and hard disk. For laptops with independent graphics cards, we fully tested their display performance. For Fujitsu P7230 with integrated graphics cards, we only tested 3DMark03. At the same time, to test the game performance gap between the Vist

First understand what is gap lock In InnoDB, there are roughly three types of record-level locks: Record, Gap, and next-keylocks.
