Too many mysqld-max processes!!
Hello, I am running mysql on linux and I have too many mysqld-max processes running at the same time. Why is that and what can I do about it apart from killing the processes after every boot?

InnoDB logs
Hello, I have a couple of questions regarding InnoDB logs' structure. -Are the innodb logs stored in the main innodb tablespace? -How is the information stored in the logs? Does it look like SQL queries as the mysql binary update logs do? -What is the difference between the mysql binary logs and the innodb logs? (apart from the fact that update logs are used in case of a manual recovery and innodb logs are used in case of a automatic recovery.)

InnoDB's inner workings + checkpoints
Hello Heikki, I have read up on checkpoint activity and innodb and there are still a few points I don't understand: -what is the chronological sequence of events for a write into the innodb tablespace? -Is it: 1. An insert sql statement is issued from a mysql client. 2. The record is stored in the log buffer. (no disk access here) 3. The record is stored in the innodb log and in the buffer pool simultaneously. (1st disk accesss) (checkpoint) 4. The record finally makes it to the innodb tablespace and is saved to disk. (2nd disk access) Can you please correct the above if it is wrong.

Help restoring data with mysqlbinlog
Victoria, Thanks for replying. How does one know what parameter to pass on as "position", in other words how do I know from what point to start the roll-forward from the binlog? What's more what format is this parameter? (timestamp, integer??) Thanks, Balteo. P.S. I tried "mysqlbinlog --help" but It doesn't tell you much - 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?

Help restoring data with mysqlbinlog
Hello all, I am trying to restore some data from the binary log and I am not sure on how to proceed. I understand restoring data is a two-stage process: 1. You start by restoring data saved with mysqldump. 2. Using mysqlbinlog, you restore the data logged in the binary log from the point where mysqldump stopped. It is on this second point that I would be grateful to get some help. My question is specifically: how does one know the value of the parameter "position" to pass on to mysqlbinlog? Thanks in advance, Balteo.

mysqlbinlog: Duplicate entry '1' for key 1
Hello, I am trying to restore some data from the binary log but I get the following error: "Duplicate entry '1' for key 1" I understand restoring data is a two-stage process: 1. You do a "source myfile.sql" to restore the data saved with mysqldump 2. You restore the data logged in the binary log using mysqlbinlog I am having the above problem at the second stage and what's more, I don't understand how mysql is supposed to know from what point to start the restore from.

Re: DESPERATE NEED FOR HELP!!!!!
Why don't you create a php script that generates SQL instead of HTML; i will repopulate your database acting as a dump? I know it will take some time to develop...
