I tried all the options to reduce history list length. But it is constantly
increasing.
Below are the current settings of purge related threads:
innodb_max_purge_lag | 100 |
| innodb_max_purge_lag_delay | 0

Hi Bill,
How big is your table? It seems to me that you might want to change your
unique keys to something like (icd9, icd10), thus guaranteeing that every
mapping will exist only once in your table. You could create a new table
with that constraint and copy all your data to it:
CREATE TABLE `ICD

The binary log is useful for more then just replication and can be used to
take incremental backups or to perform forensics on what your server has
done. I would recommend learning how to use them to your advantage over
turning binary logging off as some have recommended. Make sure you're

If you search on "mysql-bin.01" you get a lot of good info.
o They are mysql log files it contains all the queries u can view
these files with the command mysqlbinlog just man it for more details
o These are your binary log files.. you might not want to switch them
off depending on your setup -
Those are your binary logs. Â They store the data stream to be consumed
by your slaves.

Are you using replication? Â If so, you need to go to each of your
slaves and run the command 'SHOW MASTER STATUS;'. That will tell you

Hi,
In my MySQL directory, I have more than a few gig and a half sized files,
mysql-bin.01, mysql-bin.01 and et cetera. They date from today all the
way back to early 2010. I don't know exactly what those files are but I would
like to delete as many as are no longer is use since I had
