Based onStorageDisaster recovery replication solution at the Layer The replication mechanism of this technology is based on the San-based storage LAN for replication for each Io, the copied data volume is relatively large; the system can implement synchronous or asynchron

the operating system can be cleared to update it. If you can, the system does not have to be restarted. support for restart manager is added to Visual C ++ 2010, which is about to return to the king. the main applications of the restart manager are as follows: ◆ Software Update in many cases, after the software or operating system is upgraded, a restart is required to take effect. In this case, we can use the restart manager to automatically shut down the software that runs and update it. A

Of course, 200%-400% of memory can be set as VM space for both hot and cold, and it is not recommended to set up 10 times times as much memory as a VM (like my configuration). 3) Servicestack.redis client seems to have a f

System NEWFS, if the structure is the same as before, the file system most important Inode area will be all initialized, before the retention, inode management of all the important attributes of files, so simply from the file system perspective, data recovery is very difficult. Fortunately, the structure of Oracle data file is very strong, at the same time UFS file system still has certain storage regularity, can through the reorganization of Oracle

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

Therefore, when your eyelids are beating, do not treat them immediately. Instead, pay more attention to rest, relax, and maintain a good attitude. At the same time, pay attention to observe whether the eyelid jump gradually decreases or increases, whether there is a tendency to expand downward or whether there is

The system will be changed during the Windows Vista upgrade process, and the computer is in an unstable state for most of the duration of the process. If the installation is not complete or the upgrade fails, you can use rollback to automatically recover from this event. This course describes how to roll back and make recommendations for disaster recovery if the rollback is unsuccessful. I. Related compone

The major server hardware vendors (IBM,HP, etc.) provide good data protection policies (hardware or software). A well known RAID disk array (redundant array of independent disks) is a good way to protect data. In the case of SQL Server , a detailed data backup plan can be developed through a maintenance plan. Data backup strategy (full backup, differential backup and transaction log backup) Data backups are services for data recovery, so before yo

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,

brought about by natural disasters, hardware faults, and human factors, at any time, IT systems and even services of enterprises may be cracked down, resulting in Operation Break and even threatening the survival of the company. How to cope with the risks brought about by putting eggs in one basket has become the focus of many enterprise users in information construction and IT deployment and operation, disaster
