Hi all,
I'm very new to Mysql, though very comfortable with Oracle rdbms.
Users are reporting several errors regarding this message:
"Lock wait timeout exceeded; try restarting the transcation"
I've checked Oracle support note 1296631.1 I have dumped the output of the command
SHOW ENGINE INNODB STATUS
I understand this to be a locking/deadlock issue, but I'm unable to completely 'digest' the output. Which transaction is holding the lock, why is it holding the lock?
