Re: 9i standby
I'm a little late to respond, but... RAC is most certainly a significant upgrade to and renaming of OPS. There is absolutely no doubt about it. At Oracle Open World 2000, all the Oracle OPS people doing presentations found out about the name change only a few weeks before the conference and scrambled madly to change all occurrences of "Oracle Parallel Server" to "Real Application Clusters" in their 9i (nee 8.2) presentations. The handouts still said OPS (and sometimes 8.2 ), but the otherwise identical overheads (usually) said RAC and 9i. The marketing denial of this is simply because OPS got such a bad reputation - which was, in my opinion, largely undeserved. The people who actually write the code for OPS/RAC suffer no such delusions. Granted OPS/RAC is/was more complex, but the bad rep was mostly due to people trying to use OPS inappropriately - for poorly-suited applications and systems (i.e. the majority). "RAC" is somewhat simpler to set up and administer than "OPS" and performs much better, but it is still OPS with a new name. While Oracle finally admitted that OPS was a specialty product, they seem now to be saying that RAC is for anything.

Which is exactly what OPS did. You had several machines linked to a centrally stored db. One wen't down, the others picked up the slack. A fat lot I know, I never used it. But I'm pretty sure that's what OPS was all about. I'm sure they've added some functionality. At least, I *hope* they've added some functionality.

RE: 9i standby
Brian, They didn't actually say what hardware they ran on other than "Compaq". There was a little discussion about this after the actual presentation with other attendees also, but I shouldn't get too worried about de-support of this solution at all. The actual day was an Oracle/Compaq release day (with Compaq sponsoring), and they both seem to be working really well together to get this done. Even if they do write the Alpha chip off - do you really think that they would not first bundle the software in to an intel chip? :) In my opinion that is the sole reason they bought Digital out huh? Still learning all this though, and have a fair bit of reading to do I guess.. :) Mark -Original Message- McGraw Sent: Friday, July 13, 2001 03:37 To: Multiple recipients of list ORACLE-L Mark - I saw the same presentation @ IOUG.

RE: 9i standby
No it is not the upgrade of OPS as I understand. They even put OPS down themselves saying that it was sparsely used, and far to complicated to set up. What RAC does, is essentially link every machine together in to a "cluster", then each physical machine can touch the same database concurrently (probably on a central storage unit). There is no actual "standby" when this is in use, as all machines connected to the cluster work together - but if one of the machines has a hardware failure, the load is simply spread between the remaining machines.. It looks *really* cool stuff, and by *Oracles* stats, beats any other clustered databases in real world situations.

Re: 9i standby
there are actually two kinds of "standby" that they are talking about in 9i.. if you use the logminer to generate the SQL for the standby db, then you are applying SQL statements to the standby and you can run read-only transactions about it. If you go to oracle online ed, there is a presentation on high availability there that you can sign up for (free registration) and it talks about this.

Replication happens in discrete chunks and there is a distinct possibility of losing data if replication was used in banks.
