SLAVE aware of binary log file switch?
Hi all, Given a MASTER and a SLAVE. When launching the SLAVE, it knows about the binary log file used by the MASTER and the position in that log file. Say the binary log file (on the master) has reached its maximum size, so that it has to switch to a +1 binary log file: does he inform the SLAVE of that switch so that the SLAVE updates its information about the MASTER status? I'm readind the documentation http://dev.mysql.com/doc/refman/5.1/en/binary-log.html and dont see what is happening while slaving. Thank you. -- RMA.

The master does not inform the slave via an immediate communication channel, but the slave knows how to keep up because the end of the binary log file contains continuation information - i.e. the name of the next log file to fetch. OK. I'm sorry I was mislead by the output of: [mihamina@prod-ebidual ~]$ echo SHOW SLAVE STATUS \G; | mysql -uroot -px | grep 'Slave_' Slave_IO_State: Waiting for master to send event -- this Slave_IO_Running: Yes Slave_SQL_Running: Yes -- RMA.

Triggers and FOR EACH ROW
Manao ahoana, Hello, Bonjour, I just read several documentation on MySQL triggers. The way to create triggers is: CREATE TRIGGER t21_au BEFORE UPDATE ON t22 FOR EACH ROW BEGIN // ... END; The trigger I want is only on UPDATE. Is FOR EACH ROW referring to each existing row in the table, or to each UPDATEd row?

describe relation between LDAP entries
Manao ahoana, Hello, Bonjour, I have LDAP entries, and SQL tables are the relation between them. There are only relations between 2 entries. There are modem and customers entries in the LDAP directory I need advice on optimizing the way I store relations. For example SELECT * FROM customer_has_modem; +-++ | customer| modem | +-++ | a=aa,b=bb,c=ccc | d=dd,e=ee,f=ff | +-++ Is it OK? Have you another way to do it? - splitting the comma separated fields? - whatever? There might later be be a date field in this table to trace the modem movements.

Re: Help saving MySQL
Tom Worster f...@thefsb.org : my guess is that it would be better if mysql did not need to fork. the harm would be the confusion caused to users. I really dont think it is a problem. _Users_ lazzy to follow the fork will stay with MySQL under Oracle. _Users_ less lazzy will switch.
