Embodiment 1

[0039] The embodiment of the present invention provides a method for archived log transmission, please refer to figure 1 , including the following steps;

[0040] In the server cluster, ORACLE database DATAGUARD is a disaster recovery technology at the database level. This technology synchronizes the archived logs of the main database to the standby database. When a server cluster system error occurs, the redundant archived logs of the standby database are completed. Database data reappearance, so as to realize the redundancy of the archived logs of the main database, and achieve the effect of disaster recovery. At that time, when the archived logs were transmitted, the main database and the standby database usually used the business network to transmit the archived logs, which caused the blocking and delay of the upper layer business of the server , so a new archived log transmission method that does not occupy the business network is proposed.

Embodiment 2

[0050] The embodiment of the present invention also provides a system for archived log transmission, please refer to figure 2 , including; clients, master nodes, slave nodes and network switches;

[0051] The master node has a master library, the slave node has a backup library, the master node and the slave node have several network cards, and the master node and the slave node transmit data through the network switch, and the client communicates with the master power-saving and slave nodes through the network switch. To access the business network, the client accesses the main database of the master node and the standby database of the slave node respectively through the business network. In the master node and the slave node, the control information of DATAGUARD is transmitted from the master database to the standby database through the business network , and the archived logs of the main database are also transmitted to the standby database through the business network. T...

Abstract

The invention discloses a method for transmitting an archived log. The method comprises the following steps of: configuring a first directory parameter and configuring an address for storing the archived log in a main node; configuring a second directory parameter and configuring an address for backing up the archiving log in the slave node; establishing a connection string parameter through the second directory parameter, and establishing a first network between the master node and the slave node; the master node backing up the archived log to the slave node through the first network; monitoring the connection state of the first network, wherein if the first network is connected abnormally, the IP of the slave node is displayed, and the transmission network is switched, in this way, the archiving transmission network can be established through the idle network card, additional independent configuration monitoring is not needed, the configuration amount and the maintenance amount are reduced, and the efficiency is improved. According to the technical scheme of the invention, the influence on the bandwidth of the service network when the archiving log is transmitted between the main library and the standby library by the DATAGUARD function is reduced, and the service network can be switched to transmit the archiving log when the transmission network fails.

Description

technical field [0001] The invention relates to the field of data transmission, in particular to a method, system and medium for archiving log transmission. Background technique [0002] The DATAGUARD of the existing ORACLE database is a disaster recovery technology at the database level. By synchronizing the archive log of the master database of the master node to the backup database of the slave node for redundant backup of archive files, when the archive files of the master database have errors At that time, the archived logs of the standby database can be restored to the main database to achieve the disaster recovery of the archived logs. At that time, when the archived logs are transferred from the main database to the standby database, the business network needs to be occupied, and the business network is required to process the upper-level business. Therefore, when the archived log is transmitted, the upper layer business will be delayed, or even an error will occur. ...
