The thing is that most of the people on this mailing list are working full time and have families and private lives. Also, I think they are concerned that you are looking for a big commitment of time. Expecting that kind of person to give up a lot of scarce personal time is just not very realistic. I'm sure you'll look back on this in a few years when you are working full time and have an active private life yourself and realize how much you are asking. In the meantime, feel free to post questions here and I'm sure people will help as best they can. But don't look for really long answers, even to big questions like how do I design a database?. You're much more likely to get a reference to a tutorial or a book than to have someone actually explain the process in detail.

Nothing gained and everything lost, in such a move. d) If we know anything, we know that Scott and Larry are not fools. e) In the grand scheme of things, the MySQL piece of this pie is peanuts and perhaps less. This acquisition is about the big picture (hardware platform + existing Sparc base + Java, etc.). MySQL, as much as we love it, is a tiny teensy part of this acquisition, and my guess is that Scott and Larry are much more focussed on the other parts (e.g. end-to-end solutions extending from the hardware to the middleware to the Oracle apps, etc.) and in this ballpark MySQL is an interesting tidbit but not at all the focus of their efforts. Think big, baby. MySQL in this context is a tiny little ripple in the pond, having little or nothing to do with Scott/Larry's plans. Viewed from this perspective, MySQL becomes a viable alternative to such offerings as SQL Express from MS. If for no other reasons than marketing imperatives, I am confident that Scott and Larry will choose not to kill MySQL but rather regard it as both an entry platform and a position from which to upgrade to Oracle. Make no mistake about this. There are very sound reasons to upgrade to Oracle. Cost is of course a serious issue. But Oracle can do things, and has various top-end vehicles, that MySQL cannot approach. Consider, to take just one example, Trusted Oracle, upon which numerous banks bet their bottom dollar. Add to this the numerous Oracle Apps. I am no champion of Oracle in particular, but I do rtheecognize what platforms X and Y can do. If the game is defined as retrieval amongst several GB of data, then MySQL has a chance. If the game is retrieval amongst several PB of data, with security, then I bet on Oracle. Granted, this move requires a team of DBAs etc., but if you are dealing with PetaBytes then I suggest that you think carefully about which vendor is prepared to take you there. Just my $0.02 in this debate. I don't see MySQL and Oracle as competitive products. In fact I see the opposite: Oracle gets to occupy a space in the open-source community while simultanwously offering an upgrade path to multi-petabyte solutions, serious security, and so on. I don't think that Scott and Larry are out to hurt the MySQL community, and I'm prepared to bet that they will invest in the next version of MySQL, You might disagree but I challenge you to answer Why? Sheer rapaciousness? That doesn't make sense. MySQL has garnered numerous big-time players, and in what possible interest would Oracle jeapordize these investments? As several writers on this thread have said, if Oracle muddies the waters then they are prepared to move to PostGres and/or several other alternatives, not least to take the MySQL sources to a new playpen. It is clearly not in the interests of Oracle to let this happen. Far more interesting is to fold the MySQL project into Oracle's overall Linux project. Continue to offer MySQL for free, work on transport vehicles that let MySQL people migrate effortlessly to Oracle, etc. I don't mean to pretend to read Scott and Larry's minds here. But I think that the MySQL part of this acquisition, while interesting, is a small part of the rationale for buying Sun. The serious interest is in acquiring an end-to-end solution, as yet offered by nobody, including IBM and MS. This is the most significant part of this acquisition. Imagine being the salesperson of said stack. We have the hardware and the operating system and the middleware and the front-end. Click and go. IMO this is a truly formidable argument. In practice, it could be delivered as an appliance and/or a blade. And if you don't think this is formidable, then wake up and smell the coffee. This could well leap-frog certain other competitors -- which is not to say they won't catch up eventually, but it is to say that Oracle has raised the bar and it's time for competitors such as MS to jump through several flaming hoops.

Re: MySQL Master Slave Replication
Kaushal, When you set it to MASTER/MASTER replication then everything that happens on the MASTER happens on the SLAVE. Remember they are both master and slave. My situation is as fallows, I have 2 node (servers) and I have then configured for HA (high availability) failover. When node 1 goes down, node 2 takes over and when node 1 comes back up then node 1 will becomes the main node. For this I am using RHEL cluster suite but you could set up HEARTBEAT to handle the High Availability, see ha-linux.org The above is separate\ from my replication. The DB replication is handled by mysql by following the process explained on the links.

Re: MySQL Daylight Savings Time Patch - easy check
That was interesting. I have 2 rhel 3 servers and they both have been
update to handle the DST. They both yield different results when I ran the
command:
SERVER=RALPH
+---+---+
| UNIX_TIMESTAMP('2007-03-11 02:00:00') | UNIX_TIMESTAMP('2007-03-11
03:00:00') |
+---+---+
| 1173607200 | 1173610800 |
+---+---
and this for the other server :
SERVER=MAGGIE
+---+---+
| UNIX_TIMESTAMP('2007-03-11 02:00:00') | UNIX_TIMESTAMP('2007-03-11
03:00:00') |
+---+---+
|1173607200 | 1173607200 |
+---+---
Uhm.

Maybe your OS isn't patched?
Try this: SELECT @@global.time_zone;
Won't help if you are on debian which is still on 4.0.
If you get back SYSTEM, then MySQL is looking to the OS for timezone
data. And its only loaded when MySQL starts, so if you haven't
restarted MySQL since you patched your OS, you need to do that.

What version of MySQL are you using? I'm running 4.1.21, and that check
doesn't work even after I've updated (I think) the time zone tables.
I should probably eyeball the output of mysql_tzinfo_to_sql.

Yes, reload them. :-) After that, they're current! ...
After digging around on the net for a while I found an easy
way to tell
if your MySQL installation is ready for the new daylight savings time.
SELECT UNIX_TIMESTAMP('2007-03-11 02:00:00'),
UNIX_TIMESTAMP('2007-03-11 03:00:00');
This should return the same value, even though you are feeding it
different times, because this is when the 1 hr change occurs.
I get the
correct result on both of my machines. On one of them I've run the
suggested |mysql_tzinfo_to_sql command, on the other, the time zone
tables are completely empty!
Any wisdom on these time zone tables - are they ever used, should I
populate them or not?

Converting a field or converting a date?
People, I am not very savy with SQL and I need help. I have a char field that contains a date and the date is in DD-MM- and I want to sort it but the sort is wrong because 01-04-2007 comes out before 10-22-2006. Is there an easy way to provide a correct sorted output list or do I need to edit my table and convert all my fields to -MM-DD before I can sort it. Any help is welcome. Thanks, Néstor :-)
