To increase the capacity of C disk is often encountered in such cases, such as my computer hard drive now has four partitions, namely C, D, E, F, I want to increase the capacity of C disk 10GB, and D and E disk space is very limited, can not allocate 10GB capacity to C disk, only F disk has ample capacity can give C disk 10GB capacity, How do you do it? In fact d

In SQL Server, you create a database by using the ALTER DATABASE command, which enables you to modify the database's data files and log files.One, create a database1, when creating a database, the best practices are: Create one or more filegroups and set the default file groups The data files in each filegroup are the same as the kernel data of the CPU, distributing the files evenly on different physical hard disks, so that the IO is evenly distributed on different physical disks;

Right-click on the last partition to select the compressed volume,If you don't have enough disk space, be sure to back up the data on that partition.！！！ You can also choose to delete the volume,but to do so, be sure to back up the data！！！ Compress how much depending on your hard drive and how much space you want the Linux syst

Label:Today I would like to talk about a special topic in SQL Server--Instant file initialization (Instant initialization). For your instance of SQL Server, if you enable Instant file initialization, you will get a huge performance boost under certain circumstances. Instant file initialization defines how the SQL Server engine deals with the Windows operating system when new space is allocated in the data file. cause of the problem In the SQL Server default configuration, when you allocate new s

The distribution of data is mainly determined by the partition value.The DYNAMODB service is solely responsible for the management of the partition, including the number of start table partitions and partition splitting.First we need to know that a partition in Dyna

This is a creation in Article, where the information may have evolved or changed. Background The story is this: The company system has a service is pdf2jpg (actually should be ppt2jpg, just ppt2pdf This step we use seven cow cloud service to complete. In the early days, we used the crontab to get the data that the database needs to be converted periodically according to the system load. So the QPS of this service is 1/60 QPS. Yes, you do not see the wrong is so low, but it is OK, after all, the

As we all know, UTP copper cabling can often provide a more economical cost than optical fiber for 10gbase-t channels. Electronic devices used for 10GBASE-T are more complex than electronic devices used by 1000BASE-T, but they should be much cheaper than electronic devices 10gb/s fibre

does not necessarily reduce the GC execution time.GC Optimization ProcessThe GC optimization process is similar to the process of most performance improvements. Here is the GC optimization process I used.1. monitor GC statusFirst you need to monitor the GC to check the various states of the GC during system execution. Please refer to the monitoring method mentioned in the previous article to become a JAVAGC expert part ii-How to monitor the Java garbage collection mechanism.2. After analyzing t

, and determine whether it is necessary to perform GC tuning. If the analysis results show that the GC takes less than 0.1-0.3 seconds, it generally does not take extra time to do GC tuning. However, if the GC takes up to 1-3 seconds or more than 10 seconds, the system needs to be tuned for GC immediately.However, if your application allocates 10GB of memory and cannot reduce memory capacity, there is no way to perform GC tuning. In this case, you fir

However, if the GC's execution time is 1-3 seconds, or more than 10 seconds, the GC will be imperative.However, if you have already allocated
