The default five kinds of FSMO exist on the first DC of the root domain in the forest, while the relative representation host, PDCE, infrastructure master in the child domain exists on the first DC in the child domain. After the construction of the previous domain, we will perform a disaster recovery for the primary domain controller. Step three: The transfer of FSMO r

My friend's database system has a problem. The following is his solution process, which is helpful for me to learn RMAN: The following is a case: Production Machine OS down, RMAN disaster recovery When I was learning rman, I suddenly encountered a golden "good opportunity" to learn RMAN. Because it is a production machine, the following operation objective is to restore data in the shortest time, there is n

the intact data in the data file without running the Oracle Instance database Instance. As long as the data is not completely cleared or damaged, so PRM still has the hope of saving data. PRM can work based on corrupted file systems, ASM Diskgroup, and data files. If the Oracle Data Dictionary is available, it will use Dictionary to make recovery easier, even if the dictionary comes from an inconsistent SYSTEM. DBF system tablespace backup. For PRM,

Environment product: DB2 UDB Platform: cross-platform Version: 8.2 (8.1 patch 7) Problem DB2 UDB High Availability disaster recovery (HADR) is a database replication feature that provides high availability solutions for partial and entire site faults. HADR copies data changes from the source database (called the master database) to the target database (called the backup database) to prevent data loss. This

The database has now become the cornerstone of the enterprise, so it is necessary to ensure the high availability of the database. At the same time, it is also necessary to prevent unexpected incidents from causing problems in the entire data center (such as addresses and floods ). Therefore, data center high availability and disaster recovery must be considered at the same time. Using the database mirrori

data consistency groups by combining these vv into a data consistency group to achieve: not only is the target-side write order of each VV in the group consistent with the source, the group VV The write order between the sources is exactly the same as the source end. Similarly, for this reason, if you configure a double-live, an application that uses all VV should be within a data consistency group. This allows all VV master paths for an application to not be assigned to two 3par . Similarly,
