Turn from: http://www.ibm.com/developerworks/cn/aix/library/au-powerhaintro/ Brief introduction As business requirements grow, critical applications must remain available and the system must be tolerant of failures. However, the cost of these fault tolerant systems is high. As a result, these capabilities need to be provided through the application, and the application should also be economical and efficient. A high-availability solution ensures that any component of the solution fails without

In a test of the bank user POWERHA for I environment, we noticed an interesting phenomenon that we used to use the green screen to do regular operations. At the same time, there are always customers asking if there is a more intuitive way to build and manage the POWERHA environment. Today we are going to introduce you to the Web application of Powerha for I. Ent

Brief introduction Data center and service availability is one of the most important topics in the IT infrastructure and attracts more attention every day. Data replication between sites is a good way to minimize business disruption because the backup restore operation takes too long to meet business requirements, or the device may be corrupted and cannot be used for data recovery, depending on the severity of the disaster. Recovering from the cheapest (recovery takes a long time) to the most e

Objective As PowerVM uses more and more, there will be more and more cases of implementing PowerHA in a virtualized environment. Traditional PowerHA6.1 in the physical partition is a more classic configuration, PowerHA7.1 in order to adapt to PowerVM, in the development of the relevant considerations, including three: PowerHA7.1 allow 1 HA nodes only 1 network adapters, 1 Bootip And a serviceip, and Servieip can and Bootip in the same network segment

, you can consider using DB2 purescale. You can download an IBM DB2 purescale technology manual for transparent application scaling to learn more about the comparison between purescale and RAC. Of course, in this book, IBM repeatedly emphasizes that Purescale is derived from the mainframe lineage and deliberately lists some extremely unfavorable scenarios for RAC, although there is a probability size problem, however, in terms of its fundamental implementation principle, Purescale is more advanc

require any zoning configuration changes and can be performed in any server that is running AIX version 6 (including servers based on POWER4). LAM is a virtualization feature of AIX version 6 that can run on all systems that support AIX version 6, however, dynamic partitioning migration is an advanced PowerVM virtualization feature that works only with the system P servers that are based on POWER6 All operating systems, including AIX and power Linux. Workload partition migrations do not need to

chief architect of our POWERHA product. She and her team made a number of important contributions to IBM I 7.1. For example, support for V7000 and SVC in Technical Update 3. Now they are working actively on some of the most important new features in the next generation of IBM I and Powerha. As a leader in its technical field, her speech gives us a good prospect of a new high-availability feature that will

points, HA the software is still alive at the moment. And we should also see that for a long time HA The software also has some problems in the application practice. Some problems have even seriously affected their reputation and marketing. As an example of relatively "tall" PowerHA(HACMP), the proportion configured on the IBM POWER mini-machine is quite high , basically the server for the database if the number of more than 2 units, will be purchase

related products (such as VIO and PowerHA, relevant cases can be called up to confirm and assist in solving similar problems. However, if you have not called 800-IBM-SERV before, you need to know the following points. First, you should have an IBM contract number. There are multiple support levels, from the highest level of dedicated 24x7x365 support to support from eight o'clock A.M. to five o'clock P.M. for non-critical servers. You can purchase th

The CRS and database software of RAC have been installed and upgraded to 10.2.0.4. An error cannot be solved. No way onlyReinstall CRS.(Error similar to srvctl add service fails with PROC-5 [ID 466952.1]However, this error occurs when I create a database. The error is reported when the service is added .)However, the previous step took about five hours. If everything is repeated. The cost is too high. I found an IT pub expert onlineDocumentation. Reinstall CRS. Actually succeeded. My library is
