This is real world recent experience. We have automated systems that replicate data from a primary to an alternate TD server using automated
ARCMAIN and COPY processes. We have recently been replicating with ARC from LINUX and COPY to MP/RAS, during an upgrade. We find that ARC (or
COPY- unclear) somehow corrupts any partitioned primary indexes, which has necessitated a script that runs immediately after the COPY job and does
a REVAL of the pp index, which then runs fine; runs in a second or so. Once the upgrade is concluded, both the primary and alternate will be
Linux, and I assume end of ppi issue. Beyond that, we have running similar apps on both servers, without issues, other than size of server
disparities. While I am not one the official DBA team, I am not aware of significant issues, other than slow response on the on the overworked
server (being used for a load much larger that for which it was specified).
