looping error message
We are running Apache 1.3.26 with mod perl 1.26, perl 5.6.1, and mysql 3.23.49 on a Sun Solaris machine. Every now and then, one of the scripts we are runing gives the following error message: null: DBD::mysql::st fetch failed: fetch() without execute() at /usr/local/lib/perl5/site_perl/local/Calendar.pm line 1667. The really annoying thing is that the error message keeps getting written to to the error log until it fills up the disk. We are looking into the source of the error message but I was wondering if anyone has any ideas as to why the error message goes into a loop and if there is anything we can do to stop it. Thanks for any information.

innodb questions (backup and transactions)
Hey Guys, I have just a couple of questions regarding the innodb database type that I'd appreciate any advice with. I'm currently developing a custom shopping cart / backend and, due to the nature of such a system, would like to take advantage of transactions - so innodb seems the logical choice. However, I have a couple of reservations... I realise innodb does not have fulltext support built in - is the only way round this to have any data that needs to be fulltext-searched in a myISAM table? I've read that a ROLLBACK after a transaction will not rollback the myISAM tables - so I guess some app logic is required for these special cases. Is my thinking right on this issue? And secondly, I'm a bit worried about backing up innodb tables - more specifically a live backup. I've seen a product innodb sell specifically to do this but I can't really justify the licensing costs. Are there any other options for a live backup? The only others means of backup would be to shutdown the server and copy the data manually I assume? Any pointers to the above two queries greatly appreciated!

% vs localhost in user.host
I am running mysql Ver 12.20 Distrib 4.0.13, for pc-linux (i686) on RedHat
6.2 (so shoot me, I'm using an old scratch computer so I won't break
anything on the real development machine)
I tried to create a user by inserting directly into mysql.user. When I set
user.host to localhost, it works, when I set it to % it doesn't. I thought
% matched anything, and so should match localhost. In case I've missed
something in the docs, please direct me to the correct page.
I ran this, and it worked
--
mysql -u root mysql EOF
delete from user where user = 'foo';
insert into user (host, user, password) values('localhost', 'foo',
password('bar'));
flush privileges;
EOF
mysql -u foo -pbar EOF
quit
EOF
--
So then I tried the same thing, just changing localhost to %, and the
second mysql, where I try to log in as user foo, password bar (I know it's
unsafe to put the password on the command line, this is just for testing)
says
ERROR 1045: Access denied for user: '[EMAIL PROTECTED]' (Using password: YES)
--
mysql -u root mysql EOF
delete from user where user = 'foo';
insert into user (host, user, password) values('%', 'foo', password('bar'));
flush privileges;
EOF
mysql -u foo -pbar EOF
quit
EOF
--
So I tried adding this line to after the insert
select host, user, password from user where user = 'foo';
in case maybe I had botched the insert, or there were other entries in the
user table that messed things up. Here's what I got (looks OK to me):
hostuserpassword
localhost foo 7c9e0a41222752fa
hostuserpassword
% foo 7c9e0a41222752fa

Re: InnoDB file data size against MyISAM files data sizes
In my experience, I see about a 2x increase in space required between MyISAM and InnoDB. I believe this may be documented btw, check the InnoDB section of the manual. I have been using InnoDB for a couple years now on databases up to 180GB. InnoDB has been very robust and I have only once come across a corruption after a crash of the DB or the operating system (linux).

Replication Rollback
Hello everybody. I have a clarification/solution to request. I am currently in the process of designing a web application with JBoss 3.2.2 and MySQL 4.0.16. The application is a data centric application with huge list of products (tens of thousands). Sets of products are grouped into Categories. These categories are maintained in a hierarchical fashion in the database. There is no restriction on the number of levels that this categories can go to. The requirements are to help an admin user manage product categories and also to be able to bifurcate a category. To cite an example, let us take a category of Toys which has 100 products beneath it. The admin user wants to split the Toys category based on age group. he can split the category into any sub categories ( 3 Yrs - 8 Yrs, 9 Yrs - 15 Yrs, 16+). The admin user will now have to split the 100 products into these categories. He cannot leave any products in the Toys category. There are two risks associated with this: a.. The user doesn't finish the multistep process. (handled by the use of session variables) b.. The admin user needs to test the application (data changes) on a staging environment before he can confirm the changes to production. c.. The admin user needs to be able to roll back changes if he is not satisfied with the changes made. I was planning to use replication. This is described in detail at the url document(http://www.aspiresys.com/karthik/procs.pdf). The process works fine as long as the data is correct. given the approach I would like to know how I can roll the old transaction back. Also I want to know the best method to achieve this. This is pretty important and any help would be highly appreciated.

Re: Replication Rollback
Karthikeyan, replication poses no problem here. MySQL does not write to the binlog transactions which are rolled back.

The application is a data centric application with huge list of products (tens of thousands). Sets of products are grouped into Categories.

The requirements are to help an admin user manage product categories and also to be able to bifurcate a category. To cite an example, let us take a category of Toys which has 100 products beneath it. The admin user wants to split the Toys category based on age group. he can split the category into any sub categories ( 3 Yrs - 8 Yrs, 9 Yrs - 15 Yrs, 16+). The admin user will now have to split the 100 products into these categories. He cannot leave any products in the Toys category. There are two risks associated with this: a.. The user doesn't finish the multistep process. (handled by the use of session variables) b.. The admin user needs to test the application (data changes) on a staging environment before he can confirm the changes to production. c..

Re: innodb questions (backup and transactions)
Russ, you can also use mysqldump --single-transaction to back up InnoDB type tables. The advantage of InnoDB Hot Backup over that method is that InnoDB Hot Backup takes binary backups of the ibdata files. Restoring a binary backup is much faster than a table dump.

I'm currently developing a custom shopping cart / backend and, due to the nature of such a system, would like to take advantage of transactions - so innodb seems the logical choice. However, I have a couple of reservations... I realise innodb does not have fulltext support built in - is the only way round this to have any data that needs to be fulltext-searched in a myISAM table? I've read that a ROLLBACK after a transaction will not rollback the myISAM tables - so I guess some app logic is required for these special cases. Is my thinking right on this issue? And secondly, I'm a bit worried about backing up innodb tables - more specifically a live backup. I've seen a product innodb sell specifically to do this but I can't really justify the licensing costs. Are there any other options for a live backup? The only others means of backup would be to shutdown the server and copy the data manually I assume? Any pointers to the above two queries greatly appreciated!

Re: Database rollback doesn't work
Monica,
I think there was no transaction support in MySQL-2.3.2.
You should use MySQL-4.0 and an InnoDB or BDB type table.

Re: Replication Rollback
Hi Heikki, The basic problem is that I have committed the transaction and then replicated to another DB. Now I want to rollback the committed transaction. Is there a way to rollback to a particular point. This requirement is very similar to rolling back using save points. I guess an option would be to backup database before changes and restore it if the user is not satisfied with the changes he has made. One transaction in my application would affect 6-8 tables with at least 50 - 100 records getting inserted/updated or deleted.

[LONG] Connector/J SQLState 0S100 usage/meaning
Hi,
i'm trying to write a java application which handle SQLException
correctly.
To achieve that i use declarations found in sqlstate.h and SQLError.java.
Note that if someone have a good URL about SQLState error codes
i'm really interested.
then i've greped Connector/J source for SQLException throwing. This
operation show me some problems.
Connector/j throws SQLExeption with an SQLState value of 0S100 which
is not used/declared in SQLError.java nor in sqlstate.h.
Is this a correct SQLState or a typo ?
It's first used for unicode support error, this may be correct but
should anyway be declared somewhere:
(Note that lines references are for connector/J 3.0.8-stable source code)
In Connection.java near line 2049 function checkServerEncoding :
//
// Attempt to use the encoding, and bail out if it
// can't be used
//
[snip]
} catch (UnsupportedEncodingException UE) {
throw new SQLException(
The driver can not map the character encoding '
+ this.encoding + ' that your server is using
+ to a character encoding your JVM understands. You
+ can specify this mapping manually by adding \useUnicode=true\
+ as well as \characterEncoding=[an_encoding_your_jvm_understands]\
+ to your JDBC URL., 0S100);
}
But it's used elsewhere with really different meaning :
In Connection.java near line 2217 function InitializeDriverProperties.
This fuction checks that URL parameters are valid if not i think it
shoud use sqlqtate 01S00 as declared in SQLError.java line 45 :
sqlStateMessages.put(01S00, Invalid connection string attribute);
but it use 0S100 :
throw new SQLException(socketTimeout can not + be 0,
0S100);
this looks like a typo in SQLError.java or in Connection.java.
In the same function for other parameters the same problem appears :
lines 2224, 2236, 2248 and 2267.
Error code 0S100 is used again for Unsupported encoding
(same function) line 2296.
And again line 1778 in ResultSet.java function getString(int) for
unsupported encoding too.
I think having identical error code for unsuported exception and bad
parameter error is a bit confusing, for me at least ...
Thanks for any help,
Gilles.

Replication failover question.
Hi, I have a question regarding failover in a master/slave replication enviroment. Any advice/comments/links to materials are very much appreciated! Setup: Server A is Master, B is Slave. Upon A's failure, all clients requests are routed to B. Question: Upon recovery of A, how do I configure it to sync with B? The problem is that I can't find out what the bin log and position is from B since show master status is always empty. I guess B still thinks its a slave. Thanks!

These definitely look like typos. After the holidays, I will look into a
fix for these using constants in SQLError so that typos will no longer
be a problem.

100,000,000 row limit?
I was informed that MySQL has a 100,000,000 row limit. Is this true? We were planning to use MySQL for an inventory system. However, our current data (rows) for 1 year for one area is already 8.8 million. We want to place data for 5 years for 7 areas. This would exceed 100,000,000. Is there a possible work around for this? Thank you. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
