Re: RPM files
Hi Andrew, all ! AndrewMcHorney wrote: Hello I downloaded some of the document files but the file extension is rpm. How does one extract this file? If you are on an RPM-based Linux system (like SuSE, RedHat, etc), you need not extract, you can install - using the rpm program. See man rpm. If you are on any other system (Linux not using RPM, like Debian or Ubuntu; or any non-Linux), or if you don't want to install the package but just extract some files, you can get the whole contents in cpio format. The tool to do this is called rpm2cpio, see its man page. All binaries generated by MySQL (and non-binary files as well) are also available in tar.gz packages. On some few platforms, the native tar may be somewhat limited and fail on long path names, use the GNU version of tar then.

MySQL crash on FreeBSD 7
Hi all, I woke up this morning to find that our main database had stopped responding so I jumped on to see what was going on. MySQL was no longer running and the error log contained lots of... --- InnoDB: Warning: a long semaphore wait: --Thread 39439068816 has waited at trx0trx.c line 715 for 639.00 seconds the semaphore: Mutex at 0x809c002a8 created file srv0srv.c line 872, lock var 1 waiters flag 1 --- ...and ended with the following... --- InnoDB: ## Starts InnoDB Monitor for 30 secs to print diagnostic info: InnoDB: Pending preads 0, pwrites 0 InnoDB: ## Diagnostic info printed to the standard error stream InnoDB: Error: semaphore wait has lasted 600 seconds InnoDB: We intentionally crash the server, because it appears to be hung. 080710 4:34:17InnoDB: Assertion failure in thread 34382814000 in file srv0srv.c line 2093 InnoDB: We intentionally generate a memory trap.

It is also possible that this binary or one of the libraries it was linked against is corrupt, improperly built, or misconfigured. This error can also be caused by malfunctioning hardware.

Upon restart it reported that InnoDB was not shut down normally and did it's crash recovery thing without any issues. The server is running FreeBSD 7.0-RELEASE #0 amd64 with an unchanged kernel and mysql-server-5.0.45_1 installed from ports. If anyone has any idea what caused this or steps I should take to prevent it happening again I'd be eternally grateful.

SQL (standard) AFAIK demands that all identifiers (names of database,
table, view, column, ...) be constant strings in the statements,
it does not allow expressions for them.
If there are exceptions in MySQL, I am not aware of them.
To do such things as you want, you have to use dynamic SQL:
Construct the statement as a string (which does not use expressions for
identifiers), and then send it to the server.
A Unix script generating a command file which you pass to the command
line client is one way of doing dynamic SQL.
Any other client application (Perl, PHP, ...) could do the same.
The command line client can do it in SQL, using prepared statements:
Construct a string with your statement into a variable, then prepare a
statement from the variable and execute it.
Several tests in the test suite do it, this is how to find them:
cd mysql-test/t ; grep -i 'prepare.*@' *.test
Use them as a model for your needs.
HTH,
Jörg

How Can I Auto Delete my Binary Files?
I'm running a RHEL 4.1 and MySQL 4.0.26 so a lot or the more recent commands available in 5.0.x aren't available to me. Does anyone know of any scripts or anything I can use to delete files that arent being used or run by my slave servers? It's pretty safe to say that I can delete log files older than 7 days so that can eliminate the need to check for open files.

table.
[snip]
On the contrary, using the third table would eliminate all data
duplication, thus safeguarding data integrity and making maintenance easier
(think 'I want to change this setting description or make it a boolean in
stead of a text setting'). It will also use less space because of the
previous.
Ofcourse, I don't see any settings description or setting types
limitations in your schema as it is now.
If that isn't an objection, you could create the foreign key constraint on
the existing table as such:
ALTER TABLE Settings ADD UNIQUE KEY (applicationID)
ALTER TABLE Settings ADD FOREIGN KEY (applicationID) REFERENCES
Applications(applicationID) ON UDPATE CASCADE ON DELETE SET NULL
(from the top of my head, something like this)
This implies that you are using InnoDB tables !
I would however still create the third table. It will make your life much
easier when at some time in the future you decide to expand the
functionality and do indeed include limitations on the settings ('must be
boolean', 'must be any of green,red,blue', ...), to allow for validation and
such.

Well, the other thing I'm somewhat concerned about is that the column type
is TEXT. For some of the things I'm indexing, it's an INT, but I had to
create SettingValue as TEXT so that we could store text in it as well. It
seems like a waste to index on text when the underlying value is really a
number.

I think something is wrong in the process of binlog replication, like,
the 'delete' sql is discarded. and there are many errors in the error
