Tags: SQL Server 2014 log shipping13.4 Fail-Over13.4.1 Fault LocationAs explicitly mentioned in the previous sections, log shipping consists of three basic jobs: backup jobs, copy jobs, and restore jobs. Use the previous festive log transfer monitoring function to locate which job has a problem:If there is a problem with the backup job, check the primary server status.If there is a problem with the restore job, check the secondary server status, or th

Linux Kernel soft RPS for load balancing and distribution of network reception soft interruptions Routine Linux Soft Interrupt distribution mechanism and problematic Linux interrupt are divided into the upper and lower half. Generally (this is true), the interrupted CPU executes the interrupt processing function, the Soft Interrupt (lower half) is triggered on the current CPU. After the hard interrupt processing is returned, the soft interrupt is star

rps/rfs principle in Linux kernel network In the last chapter, explained the network soft interrupt's mechanism and the optimization in the whole, but in the RPS and the RFS place did not completely explain clearly, only has described its overall function and involves the original intention. This article, further depth and understand the RPS and RFS mechanism. 1

pressure and improve data processing speed. Some introductions of irqbalance Irqbalance is used to optimize interrupt allocation, which automatically collects system data to analyze usage patterns and puts the working state in performance mode or Power-save mode based on system load conditions. In performance Mode, Irqbalance distributes interrupts as evenly as possible to each CPU to take advantage of CPU multicore and improve performance. When in Power-save mode, the Irqbalance allocates inte

First, what is log shipping?The principle is simple, three action six words: Copy------Restore with backup.If a person completes this three action, it can only be called a log porter, and the SQL Server job automatically completes, called log shipping. The same thing, not the same grade, so the term is not the same.Second, what problems can log shipping solve?Res
