Prevent user from changing passwords?
I have been looking high and low but am having trouble finding good info. I need to try to lock down mysql with strong passwords password expiry yadda yadda. I've looked at securich and am not sure I want to use it. All I really want is to prevent users from be able to change their password directly. If I can do that, then strong passwords, password expiry etc are all very trivial using some sort of script/webpage whatever to change passwords. Is there a way to prevent users from being able to change their password other than modifying the code to break set password? -- www.suave.net - Anthony Ball - a...@suave.net -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Excuse me.

Re: libmyisam help...
Heh... it seems like a perfect solution to me... I am loading a few million records a day into tables... building a new table and swapping out the old... I have to process the data a little, so to speed it up I've been forking children and passing 1 record files to load into LOAD DATA INFILE to keep it paralell... I figure if I write it straight into the apam, I wont have to hassle with all the forking around, so to speak... may even pick up some speed.

Re: can anybody tell me!!!
Do you have the date field keyed in the table definition? I assume you have numbers after the date, or text, otherwise you should be doing an = without the %... Really to speed it up you should have a date field you query on, which is keyed, and whatever is in the record after the date should be in a separate field...

Problem restricting a large left join...
I have a database of financial data that I am try to match a holdings file against... The holdings file has cusips that I look up in a lookup table to identify what dataset/table they are in. I need to check that the cusip is in the lookup table, and that it has the proper type before I grab any external info on it. The problem is that I have a highly normalized structure, and am using left joins so that I can retain the info from the holdings file and just not get the extended data. The table structure is a follows... Holdings +-lookup +-lookup info +-datasets +-dataset types I left join the holdings to the lookup file on cusips, then get the ids to left join into the info table which links cusips to their datasets. I left join down the line until I get the type. The problem is... I want everything beyond the holdings table to fail if the cusip is not present or if it is present and the type specified in the holdings file does not match the type at the end of the chain. Can this be done? The current query I am working with is below it is trying to get a summary of all the types with their counts.

Query speed seems wrong...

Re: Should I use a MERGE table?
Hrm... so it is going to need to rebuild all the indexes, not just the table I am adding... doh... oh well, should still be faster, I'd guess. Probably my best bet in this case is to create a new merged table with the new table and all the other old ones, then replace the old merged table with the new merged table.

Your table names need to be unique. Then it should work just fine. o If you do rename a table that is part of the merge, you will need to rebuild the merge table. o If you want to reindex the tables that are merged, be sure to either drop the index in the merge table or drop the merge table BEFORE you reindex the real tables. This is not fatal if you forget: just you might get weird errors. o If you do a SELECT ...

I am thinking that I can create a new table, and replace the proper underlying table with the new data. That way I don't slow doen the lookup table when I am loading, and I can load my data MUCH faster by loading with no keys. Am I right in thinking this way. So I can make a muni lookup and a CMO lookup and an MBS lookup but just select from the merged table for a cusip in any of them? This is all read only data (except the initial load) This would be very good... since I want the data to load quick, and may be loading hundreds of thousands of records at a time. Merge table sound like they fit the bill. Beware that they are very finicky and the columns MUST be the same and the index order must be the same.

A Way to protect DBI passwords in perl
Hi all, just thought I'd let people know. I recently developed a way to pass protected config file data to unprotected perl scripts (system user scripts/cgis). The project can be found at http://psc.sourceforge.net/ It is a C setuid wrapper that opens a protected file and drops its priviledge, then execs the proper perl script leaving the filehandle available to it. There is then a module Config::Secure, which initializes the script and optionally parses the conf data. I originally came up with this idea in the search for a way to pass DBI passwords to scripts that needed to be available to users but connected to a database, so I thought others here might appreciate it. It is still alpha, but I would appreciate any input. The project is all GPL, free for use.

Re: Need examples of companies using mysql
Unless you're going to have a LOT of users accessing a HUGE database, the system you've outlined below will be overkill (do you have any current usage statistics ? Are you using the system (is it an E450 ?) for any other applications/processes ?). It would be, if it was dedicated to mysql :) One of their concerns is load testing, which we haven't done a lot of yet. I'm confident it'll hold up, I am a little worried it may generate enough load to annoy them, but worse comes to worse we can set up a dedicated box. -- ___ __ ____ _ _ _ _ / __)( )( ) /__\( \/ )( ___) ( \( )( ___)(_ _) \__ \ )(__)( /(__)\\ / )__)) ( )__) )( (___/(__)(__)(__)\/ ()()(_)\_)() (__) I/O, I/O, it's off to work we go... - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

Need examples of companies using mysql
Now that our use of MySQL is being questioned (but they are pretty much convinced). What the higher-ups want to know is a few examples of medium to large companies using mysql for mission critical stuff. If any one can provide some I would be much appreciated. We are a financial company using mysql to back a bunch of our new fast-cgi stuff that is about to be opened to users, so anything in that genre would be all the better. Examples of generally what kinds of machines there are run on could be cool too, but by no means necessary. We are currently running on Solaris 2.7 with like, 4 processors and 4 gigs of RAM, I myself have full faith in mysql.
