I can enable the innoDB plugin, but except for the plugin

| InnoDB              | ACTIVE | STORAGE ENGINE     | ha_innodb_plugin.so ...

I cannot make the information_schema tables appear: 

| INNODB_TRX          | ACTIVE | INFORMATION SCHEMA | ha_innodb_plugin.so ...
| INNODB_LOCKS        | ACTIVE | INFORMATION SCHEMA | ha_innodb_plugin.so ...
| INNODB_CMP          | ACTIVE | INFORMATION SCHEMA | ha_innodb_plugin.so ...
| INNODB_CMP_RESET    | ACTIVE | INFORMATION SCHEMA | ha_innodb_plugin.so ...
| INNODB_CMPMEM       | ACTIVE | INFORMATION SCHEMA | ha_innodb_plugin.so ...

How to repeat:
1) this is in configuration:


(as listed in http://dev.mysql.com/doc/refman/5.1/en/news-5-1-38.html

"The plugin-load option here is formatted on multiple lines for display purposes but should be written in my.cnf using a single line without spaces in the option value. On Windows, substitute .dll for each instance of the .so extension.")

USE information_schema;

SELECT plugin_name, plugin_version, plugin_library FROM PLUGINS WHERE plugin_name = 'InnoDB';
plugin_name  plugin_version  plugin_library      
-----------  --------------  --------------------
InnoDB       1.0             ha_innodb_plugin.dll

SHOW TABLES LIKE 'inno%'; -- empty set

This is contradictory to documentation in my understanding.  From the quoted passage it should work with this configuration setting.  

The plugin is in C:\Program Files\MySQL\MySQL Server 5.1\lib\plugin (obviously as it loads without specifying path in my.ini).

Suggested fix:
when cheking those:

I find nothing usable. 

Either the tables are not supposed to appear in Windows wiht this version (and docs are wrong), or windows version is buggy.

I forgot to tell that the server is the 64 bit build (if it matters).

What's the result of "show plugins;"?

[9 Sep 2009 7:53] Peter Laursen
"SHOW PLUGINS" returns 

Name        Status    Type            Library               License

partition   ACTIVE    STORAGE ENGINE  (NULL)                GPL    
InnoDB      ACTIVE    STORAGE ENGINE  ha_innodb_plugin.dll  GPL    

.. and I believe the statements I provided also tell (only plugins irrelevant for the discussion were filtered).

Thanks, Peter! We have tested the plugin on 32/64 bit Windows XP, but never tried on Windows 7.
[9 Sep 2009 15:50] Peter Laursen
Was it 32 or 64 bit windows XP that was tested?
Was Vista also not tested?

Could anybody at InnoOracle/MySun dream on testing on RedHat9 and not more recent Linux's before releasing?

just noting that I tried mysql-advanced-gpl-5.1.38-winx64 on 64-bit XP and it works fine running it like this:

mysqld --console --skip-grant-tables --ignore-builtin-innodb --plugin-load=innodb=ha_innodb_plugin.dll;innodb_trx=ha_innodb_plugin.dll;innodb_locks=ha_innodb_plugin.dll;innodb_cmp=ha_innodb_plugin.dll;innodb_cmp_reset=ha_innodb_plugin.dll;innodb_cmpmem=ha_innodb_plugin.dll;innodb_cmpmem_reset=ha_innodb_plugin.dll

mysql> show tables like 'innodb%';
| Tables_in_information_schema (innodb%) |
| INNODB_CMP_RESET                       |
| INNODB_TRX                             |
| INNODB_CMPMEM_RESET                    |
| INNODB_CMP                             |
| INNODB_CMPMEM                          |
| INNODB_LOCKS                           |

@Shnae .. 

You specify options on the command line. I specified in configuration (in order to run MySQL as Windows service). 

Could you try putting options in configuration and I will try from command line (what I should have thought about of course).
[9 Sep 2009 18:39] Peter Laursen
yes .. WHEN started FROM command line

C:\Program Files\MySQL\MySQL SERVER 5.1>cd BIN

C:\Program Files\MySQL\MySQL SERVER 5.1\bin>mysqld  --IGNORE-builtin-INNODB --pl


USE information_schema;

Tables_in_information_schema (innodb%)

(a detail to observe with this test is that options were still in my.ini too - but it probably does not matter) .. so maybe it is only a problem with reading from the .ini or running as a service? If so it is not the first time this happens!

Error log has this from last server start where plugins  loaded successfully:

090909 20:25:51 [Note] Plugin 'FEDERATED' is disabled.
InnoDB: The InnoDB memory heap is disabled
InnoDB: Mutexes and rw_locks use Windows interlocked functions.
090909 20:25:51  InnoDB: highest supported file format is Barracuda.
090909 20:25:51 InnoDB Plugin 1.0.4 started; log sequence number 4232908652

090909 20:25:52 [Note] mysqld: ready for connections.

an earlier restart where loading plugins failed is logged like this:

090909  9:39:47 [Note] Event Scheduler: Loaded 0 events

a clarification: On my environment (Windows7 64 bit, MySQL 5.0.38 64 bit):

1) when starting and entering options from command line and running as a 'user program' plugins are loaded
2) when starting as a service with options in configuration file all plugins are not loaded
but there is of course also an intermediate variant:
1½) starting from command line as 'user program' specifying options file in the command line.
.. and this (1½) I have not tried.

Thank you for the feedback.

Could you please try to start from command line, but specify options in option file and see if problem is repeatable with such setup. Please also send us full error log file.
[10 Sep 2009 8:26] Peter Laursen
I am very busy now.  Can you tell what is the problem here:

C:\Program Files\MySQL\MySQL Server 5.1\bin>mysqld --options-file="C:\Program Fi
les\MySQL\MySQL Server 5.1\my.ini" --IGNORE-builtin-INNODB --plugin-LOAD=INNODB=

.. it does not start the server, but no error appears in console.  I execute cmd.exe with explicit admin privileges.

(and very frankly: I do not find it is my job to do this unless you have already tried!)
[10 Sep 2009 8:46] Peter Laursen
Ok .. it should be only

C:\Program Files\MySQL\MySQL Server 5.1\bin>mysqld --options-file="C:\Program Fi
les\MySQL\MySQL Server 5.1\my.ini"

but after trying this something is terrible wrong. I cannot start the service

C:\Windows\system32>net start mysql51
Systemfejlen 193 opstod.

*** er ikke et gyldigt Win32-program. 

(mysql 5.0 and 5.4 is no problem). So I guess I will have to try reboot or even reinstall.
[10 Sep 2009 8:48] Sveta Smirnova
Thank you for the feedback.

I already tried, but could not repeat described problem.
[10 Sep 2009 9:10] Peter Laursen
hhmmm ..

after reboot and reinstall (as repair) I cannot start the service.  So it will take a little time. Trying Windows 'System Restore'.
[10 Sep 2009 9:47] Peter Laursen
I uninstalled MySQL 5.1, removed the service with 'sc' command (as the uninstaller does not on 64 bit windows systems), renamed the old basedir and datadir.

After a fresh install it works fine - also when running as service.

Marking as "closed".
