Before you can create a logical repository, you must first create a physical repository, and for how to create a physical library, refer to the Data Guard series (4)-Creating a physical repository without stopping the main library. 1. Stop the Log Application service on the physical repository sys@jkka> ALTER database RECOVER MANAGED STANDBY database CANCEL; Database altered. 2. Reset the main library to prepare for future role conversion

At present, many IIS firewalls are essentially an ISAPI filter, and the essence of the defense of SQL injection attacks is keyword filtering, as mentioned in my previous essays in the development of Web Server guard. However, most of the IIS firewalls currently have a vulnerability: If the keyword contains an escaped percent sign (%), the request filtering and blocking of these IIS firewalls will be bypassed, containing the requests filter for IIS 7.0

The data guard provides the following three kinds of protection modes: 1 Maximum protection mode (Maximum Protection)"Maximum protection" here refers to the maximum protection of the data is not lost, that is, at least one standby and primary maintain real-time synchronization, but this is costly, that is, when a transaction is committed, not only to write to the primary section of the online redo log, There's also a standby redo log written to at le

database needs to be shut down, such as hardware and software upgrades, the standby database can be switched to the primary database to continue its external service, which reduces the service stop time and the data is not lost. If the exception causes the primary database to be unavailable, you can also force the standbydatabase switch to primary database to continue external service, where the degree of data loss is related to the level of data protection configured. So primary and standby ar

Thank you for using the "Guard against God • Host management system" V3.1, which supports Windows Server 2003/2008/2012, with 32-bit and 64-bit, directly open configuration Web sites, FTP stations, and SQL Server and MySQL, is a great helper for you to open and manage virtual hosts.

Oracle9i data Guard protects against the occurrence of a disaster by using a database called standby. It synchronizes the primary database database with the primary DB database by uploading and applying the redo logs to the standby database databases: You can write the redo logs directly from the primary DB database to the standby database to complete disaster protection with no data loss at all. This will result in a certain performance penalty for

Oracle Data Guard is an important configuration parameter. Oracle Data Guard provides one or more backup databases for the production database (a copy of the database ), to ensure that data is not lost when the master database is unavailable or when exceptions occur, and continue to provide services through the slave database. For the configuration of Oracle DG, we can use Grid Control or Data
