Subject: RE: SharePlex SummaryNo penalty. HP-UX is 64-bit os running on a 64-bit chip. Why would 64 bits impose anypenalty? Running 64 bits is what comes naturally. Running 64 bits means that sizeof(void *) will return 8 instead of 4.That, in turn, means that SGA can grow much bigger because you don't have 4G limit and that your files can growextremely big. If anything, 64 bit is much faster, because it can calculate with much bigger int's and doubles.Hopefully, your box has PA 8600 init and not Itanic. If latter is the case, I have no idea whatsoever about what youmight expect. On the other hand, who will ever need more then 640K RAM?--

Subject: SharePlex SummaryFirst thanks to every one who responded both on the list and to my private email:
The consensus appeared to be:
1. SharePlex is overly expensive for the functionality delivered and
2. Oracle has caught up in 9i for much of the functionality
3. Some features of Oracle like IOT's may present some problems.We are on HPUX and 9i is 64 bit only on that platform. I have been told that the 64bit code imposes a 20 - 25% performance penalty vs the 32 bit version of 8.1.7. Can anyone address this from experience?

Title: Message
Yes we
are PA risc rather than Itanic. The analysis I heard was the 64 bits (8
bytes) take longer to get into the CPU itself as the buss had to transfer more
data, that 64 bit instructions can take longer for that reason. Without
testing who can know. No time yet to test.
