replication software

Anyreader is a corrupt file and data replication software that can effectively copy and save files from any type of disk or wrong connection, such as CDs, DVDs, network drives, flash memory, Zip disks, floppy disks, and other damaged data that cannot be read by conventional means.Anyreader supports the recovery of interrupted connections from remote computers (breakpoint continuation), especially for unstab

get the _file program to run the absolute path and include the filename, so we can open it and read it. File is a static method of document operation, it is only responsible for open, close, create and delete files, read and write to the file, it will be FileStream to operate. This is just the entire copy file, very simple. The nature of the virus can be attached to other programs or files, the whole process is more complex. First, you need to know a lot about the structure of the executable, d

Program The following functions must be implemented. First, the running interface is not displayed during running. Of course, you can still see the process in the task manager, and the virus that is deep on the road cannot be traced. Second, the program copies n copies in the running directory. Third, recursive replication is used, that is, the first program generates the second program, the second program generates the third program, and so o

Condition: In the same version of the operating system, copying a database involves copying software and database files as follows:1. Package files in the Oracle Installation Directory of the source database:Js_znjh_1./app/oracle $ tar cvf oracle.tar admin product utils 2. FTP Transfer packetsJs_znjh2./app/oracle $ ftp 134.96.14.39Connected to 134.96.14.39.220 js_znjh_1 FTP server (Version 4.2 Sat Sep 8 09:49:58 CDT 2007) ready.Name (134.96.14.39: ora

Requirements for the character set (collation) on the destination database when implementing the logical replication software1. When the destination database is an Oracle database, it is important to ensure that the character set of the destination Oracle database is consistent with the character set of the source Oracle database.2. When the destination database is a MSSQLSERVER database, it is important to ensure that the destination MSSQLSERVER user

new event. The I/O thread writes these events to the relay log.The last step of SQL slave thread processing this process. The SQL thread reads the event from the relay log, replays the event, and updates the slave data so that it is consistent with the data in the master. As long as the thread is consistent with the I/O thread, the relay log is usually located in the OS cache, so the overhead of the relay log is very small.In addition, there is also a working thread in the master: Like other My

to Scale Out by simply adding servers and copying applications.Because of its special nature, the database is not so easy to Scale Out. Of course, various database manufacturers have been striving to make their own database software as convenient as the conventional application server, and have indeed made some functions, scalability is basically the same as that of Web application servers, such as logic replicat
