Hi, I'd like to take a quick survey and also get some feedback on the following situation: We are looking to implement a high-availability, fault tolerant database architecture for a handful of database applications which have currently been implemented using UDB on AIX as their database platform. Our architecture group is in the process of designing an infrastructure that includes multiple UDB AIX database servers that are tied together via HA-CMP in a mutual failover configuration. I'm also looking at DB2 on OS/390 as an alternative solution for this high-availability, fault tolerant enterprise database server. Our current DB2 for OS/390 environment includes a 4-way data sharing architecture, and we are using sysplex distributor to be able to connect to our data sharing group via DB2 Connect on AIX. The handful of applications that are already in place that would require this high-availability, fault-tolerant architecture are fairly small in terms of size of data and volume of transactions, and are not using any UDB specific functionality. In other words, I believe that the conversion effort to the application that would be required to move the databases from AIX to OS/390 would be fairly minor. So my questions are this: 1) What are your opinions on building a completely new infrastructure to support this HA/FT architecture using HACMP on AIX as opposed to using an HA/FT infrastructure that is already in place, i.e. DB2 on OS/390? 2) What are your experiences (good or bad) with using HACMP to provide fault-tolerance for a UDB on AIX database architecture? 3) How many of you have implemented, or plan to implement, distributed applications where DB2 on OS/390 is used as the database server? Thanks in advance for any information you are willing to pass along.
