MySQL replication and reverse replication?
Good day all I am hoping everyone is well. Can someone perhaps assist me with some resources on the following topic one of our clients are running a MySQL 5 master/slave replication setup. There is a DR test schedule during next month, however they want the slave server to become the master and the master server to become the slave server. I am busy looking into how to setup a master / slave replication, however I am trying to find out how to do the relevant changes as mentioned above. The next test they then want to do is to test the switch over to the slave server in cases where the master server should fail. I am however not that experienced on MySQL as yet and cant seem to find specific references on how to do this change over? any ideas or resources will be appreciated. Regards Machiel
Re: Unique ID's across multiple databases
I may have missed what you are trying to do here. NoSQL is really a bad name and should really be renamed to NoREL instead. NoSQL implementations are not used just because of limitations of traditional RDBMS when it comes to sheer traffic volume, they are also used because they scale horizontally very well. When I was reading though all these emails it seems to be you would have 200+ nodes here with the SAME data. Maybe that's not what you are trying to do? I also did not know the software for maintaining the data was already in place.

Which particular incarnation of NoSQL are you thinking of ? Also, I suspect rewriting all 200 clients' services is not going to be an option :-) -- Bier met grenadyn Is als mosterd by den wyn Sy die't drinkt, is eene kwezel Hy die't drinkt, is ras een ezel -- - Johnny Withers 601.209.4985 joh...@pixelated.net
Capitalize Input via Auto Complete?
I am new to MySQL coming from PostgreSQL noticed a really annoying issue. When I select a database, and try to auto complete in MySQL, it doesn't capitalize the MySQL statements. It's irritating to me to only be able to auto complete statements like 'SELECT', 'ALTER', 'INSERT' only if I hold down the shift key or caps lock key while typing. Is there a way to force MySQL to auto complete commonly used statements while typing them in lowercase which is normal behavior in PostgreSQL?

RE: Crashed Table - How to report/prevent?
Innodb doesn't suffer from corruption issues nearly as often as myisam tables, and it is able to recover on its own in many cases (crash recovery.) In my experience, if innodb does get corrupted, it's most often because of hardware problems. You could consider using it instead. -Original Message- From: Steve Staples [mailto:sstap...@mnsi.net] Sent: Monday, September 13, 2010 7:03 AM To: mysql@lists.mysql.com Subject: Crashed Table - How to report/prevent? Good day MySQL! I had a table that crashed last night. There is a cron function that goes out every 6 hours or so, that does a quick table backup (it's also replicated, it's just something that we have running now). ANYWAY, I think it crashed early in the evening, but when the backup ran, it looks like it marked it as crashed finally (which was about 4 hours later). The table was able to be read up until then, but it looks like it wasn't able to be written too. What I want to know is, is there a quick and easy way to maybe every few hours, check to see if there are any crashed tables or whatnot? This is only the 2nd time in the last 1 1/2 years. the table that crashed, is a table that gets created every month, and is about 5gig in size at the end of the month (it has a lot of records/fields in it which is why i create a new one every month). I could write a quick routine that goes and 'shows' the tables, and if it fails, then repair it (or report it back to me via email or something). Any ideas on a way to automate something that is efficient and quick?

RE: no success (was: hard disk crash: how to discover the db?)
With PHP, a blank page usually means it's generating an error, but not displaying it in the browser; this is often disabled for security reasons, but makes debugging harder. First step should be to get PHP to spit out the actual error. There should probably be a setting in the mediawiki configuration for this, or see the PHP docs for error reporting. -Original Message- From: Uwe Brauer [mailto:oub.oub@gmail.com] On Behalf Of Uwe Brauer Sent: Monday, September 13, 2010 10:35 AM To: George Larson Cc: andrew.2.mo...@nokia.com; mysql@lists.mysql.com Subject: no success (was: hard disk crash: how to discover the db?)

I have re installed the mediawiki software and then I tried to open the corresponding wikipage, but only see empty pages. There are several reasons for this: - when the hard disk crashed the database was damaged, as a matter of fact when I have a look into the /var/lib/mysql/maqwiki directory most of the files are very small in size with the exception of searchindex.MYD and searchindex.MYI. I have no idea whether this is normal. - I did not do the recover process correctly. Is there any hardcore mysql command I could use to check the database? - the connection between the mediawiki conf and the data base is broken. I will ask in the mediawiki page about this. Any advice and help is very much appreciated.
