Introduction: DB2Conditional processors play an irreplaceable role in stored procedures. In DB2,SQLThe stored procedure can use the DB2 Condition processor (Condition Handler) to processSQL Error(SQLERROR), SQL warning (SQLWARNING), no data (NOT FOUND) three common conditions and your own defined trigger conditions, you can use include EXIT, CONTINUE) three condition processors, including UNDO and UNDO. The following describes the detailed analysis of

Multicore processors are also known as on-chip multi-core processors (chip multi-processor,cmp). 1. Popularity of multi-core processorsBefore Multicore appeared, commercial processors were dedicated to the development of single-core processors, and their performance has been extreme, only increasing the speed of single-core chips will generate too much heat and can not bring corresponding performance improvement, but the CPU performance needs are larg

Linux has always adhered to the symmetric multi-processing mode, which means that compared with other CPUs, the kernel does not have any bias towards one CPU. However, the multi-processor machine has many different styles, in addition, the implementation of the scheduler varies with the hardware features. We will pay special attention to the following three different types of multi-processor machines: (1) s

Proxyhandler processor (proxy settings)Using proxy IP, this is the second trick of the crawler/anti-crawler, and is usually the best.Many websites will detect the number of times an IP is visited (through traffic statistics, system logs, etc.), and if the number of visits is not as normal, it will prohibit access to this IP.So we can set up some proxy server, change an agent every time, even if the IP is forbidden, can still change the IP to continue

According to the symptom reference provided in the printer user's manual, this behavior is an error when the printer processor is running. The aut

Method One, turn off the core frequency function in the BIOS. Into the BIOS, the cursor moved to the advanced advanced settings inside, advanced Frequency/voltage control, and then to the power technology, find the line with the red lines open, select Enabled Press F10 save can. Method Two, use power management shutdown. We can adjust the Power management mode to "High-performance mode", and the processor maximum frequency set to 99%,

Annotations are no more useful than annotations if there is no method or work for reading annotations. In the process of using annotations, it is important to create a use of the annotation processor. The Java SE5 expands the reflection mechanism API to help programmers quickly construct custom annotation processors. Annotation Processor Class Library (java.lang.reflect.AnnotatedElement): Java uses the an

Intel's next Generation 4000 series codenamed "Haswell" processors are expected to be available in a matter of weeks, and the price of the series of processors is now being exposed on the Internet. Although it will not be available until June, the price comparison information for the Haswell 4000 series with the Ivy Bridge 3000 series has now appeared on the Intel website. Given that there are multiple agents under Intel, the recommended retail price on the website is only suggested by Intel.
