Mysql – Clarification on MySQL Workbench Options File Configuring

configurationMySQLmysql-workbenchwindows

When in the MySQL Workbench tool, configuring the "Options File," I see a drop-down in the lower right corner with the options:

client
mysql
mysqld

By default, 'mysqld' is selected and I see my configuration file's (which is loaded and in use) absolute path, opposite (left) of the aforementioned drop-down. When I alternate between the different drop-down options, the fields change in the various tabs of options that are modifiable. I expect this behavior. However, what I don't understand is what the 3 drop-down options are for, overall. I see the 'Apply' and 'Discard' button, so I'm under the assumption they're there for a reason. I don't know what the differentiation is intended for or how it would impact my server if I were to select versus the other and click Apply.

Can someone explain to me what these are for and the impact they have? I've tried researching this issue, already, but have had no luck with any explanation to this.

Thank you!

The options file in MySQL is a human-readable text file, typically called my.cnf on Unix and my.ini on Windows. This single file contains configuration entries for all things MySQL, including the server, and the client library, and the various other official client utilities.

The screen you're referring to is a glorified configuration file editor for that file.

Within the file there are "groups" with headers in brackets, that determine which portions of the file are read by the different components of MySQL -- the command line client hast its [mysql] section, the various client utilities (like mysqlcheck) will also read what's in [client], and the server itself is configured under [mysqld]. Some of the other utilities may also have their own optional sections, for utility-specific features and options that would not be valid for all client utilities, like [mysqldump].

What they're doing here is letting you edit different sections of a single file, without actually telling you what they're letting you do.

Take a look at your local options file, and this part of Workbench will perhaps be a little more intuitive.

MySQL 5.5 InnoDB = OFF

Sounds like an issue with MySQL Workbench.

MySQL 5.5 has a default storage engine of InnoDB.

In fact, the option default_storage_engine is predefined as follows:

MySQL 5.5.4 and prior, MyISAM
MySQL 5.5.8 and after, InnoDB

There is another option called storage-engine, which was deprecated as for MySQL 5.5.3. Keep in mind that MySQL 5.5.8 was the very first GA release.

I would strongly suspect MySQL Workbench if it is coded to check storage-engine instead of default-storage-engine. This would allow MySQL Workbench to monitor older release of MySQL.

I have some queries you can run against the INFORMATION_SCHEMA

CAVEAT

In each query, you will see (SELECT 3 pw). The pw stands for the Power Of 1024 to display the results.

(SELECT 0 pw) will Display the Report in Bytes
(SELECT 1 pw) will Display the Report in KiloBytes
(SELECT 2 pw) will Display the Report in MegaBytes
(SELECT 3 pw) will Display the Report in GigaBytes
(SELECT 4 pw) will Display the Report in TeraBytes
(SELECT 5 pw) will Display the Report in PetaBytes (please contact me if you run this one)

Here is a report query with a little less formatting:

SELECT IFNULL(db,'Total') "Database",
datsum / power(1024,pw) "Data Size",
ndxsum / power(1024,pw) "Index Size",
totsum / power(1024,pw) "Total"
FROM (SELECT db,SUM(dat) datsum,SUM(ndx) ndxsum,SUM(dat+ndx) totsum
FROM (SELECT table_schema db,data_length dat,index_length ndx
FROM information_schema.tables WHERE engine IS NOT NULL
AND table_schema NOT IN ('information_schema','mysql')) AA
GROUP BY db WITH ROLLUP) A,(SELECT 1 pw) B;

Give it a Try !!!

UPDATE

I just ran the first query as is on a client's DB

mysql> SELECT IFNULL(B.engine,'Total') "Storage Engine",
    -> CONCAT(LPAD(REPLACE(FORMAT(B.DSize/POWER(1024,pw),3),',',''),17,' '),' ',

    -> SUBSTR(' KMGTP',pw+1,1),'B') "Table Size" FROM
    -> (SELECT engine,SUM(data_length) DSize,SUM(index_length) ISize,

    -> (SELECT 3 pw) A ORDER BY TSize;

It works as is.
