I setup a new server, running 5.6.

I want to move the default data folder to a faster disk. Some google searches say to move the data folder and update the location in the conf file. So I changed it like this:

#datadir=C:/ProgramData/MySQL/MySQL Server 5.6/Data
datadir=I:/Data

I moved all the contents of the old data file (after shutting down the server) and started back up.

No luck.

I get this:

[Warning] InnoDB: Cannot open table mysql/slave_master_info from the internal data dictionary of InnoDB though the .frm file for the table exists. See http://dev.mysql.com/doc/refman/5.6/en/innodb-troubleshooting.html for how you can resolve the problem.

I know it is accessing the new data folder, becuase it updates the error log there. What am I missing?

I am new to mysql. I am having the above error. My program works fine on the test server, but when I moved it to production I get the above message. I have verified the odbc's are the same on both servers. This is the first time we have added a new database to the production environment. I have reviewed the various boards and find the answers somewhat confusing and contradictory. I can access the production database via MySQL and via PhpMyAdmin. Yet it fails when the application tries to connect. Can someone give me some direction on how to systematically resolve this? Many thanks.

Is there are way to have some sort of friendly name for the DB?

I don't want to rename the database as everything is created automatically and there are just to many dependencies I would just rather have some friendly name like Production or Test be visible so I (and others) know what is being worked on.

However, when I tried to find the bin and lib directories and the libmysql.lib and libmysql.dll I could not find them. I am aware that for Windows 7 the installer installs items under C:\ProgramData\ as well as C:\Program Files and C:\Program Files (86).

I am trying to get mysql to run as a service via systemctl. I have never had any issues getting it to run under service command but now I cannot get it to run under systemctl. I thought it had to do with using chroot but even that doesn't seem to be the problem.

If I run the ExecStart command by hand all is good -- just wont start via systemctl

≪ Previous: mysqld.service and redhat 7 systemctl (no replies)

Good afternoon,
I have included MySQL installation in another installation procedure, hence my possibilities are limited.
I have added references towards internal directories in the file my.ini, as follows:
[mysqld]
basedir=$UM_10$
datadir=$UM_10$/data
wait_timeout=500000
sql-mode='NO_BACKSLASH_ESCAPES'
[WinMySQLadmin]
Server=$UM_10$/bin/mysqld-nt.exe

I have installed MySQL in the directory "C:\brol" and I have used "C:\brol" as $UM_10$ entry, but this gives problems:
First, my.ini changes into:
[mysqld]
basedir=C:\brol
datadir=C:\brol/data
wait_timeout=500000
sql-mode='NO_BACKSLASH_ESCAPES'
[WinMySQLadmin]
Server=C:\brol/bin/mysqld-nt.exe

and then, MySQL is not starting up.

After quite some investigation, I have found out that this is due to the "\b" which can be found in the directory name "C:\brol": it seems that "\b" is wrongly understood as "backspace", although I have mentioned the "NO_BACKSLASH_ESCAPES" entry, but this seems only to have effect while working with SQL commands.

Does anybody know if it is possible to tell MySQL not to interprete "\b" as a backspace, not only while working in SQL, but also basically while being started up?

Thanks
Dominique

Though it is not directly related to Oracle Mysql 5.6, I am guessing some one can help me moving my inestigation in right direction:

We are in process of upgrading our (Percona) Mysql 5.5 mysql servers to Mysql 5.6. We have upgraded all our slaves except one.
However, we have observed that for the same workload, 5.6 slaves are consuming more user CPU.

CPU utlization on 5.5 slave continues to be lower. For comparison, we have setup an additional slave on Oracle's community Mysql 5.6. Here the cpu utilization is lower.

Does the percona Mysql 5.6 consumes more cpu than previous version (5.5) or Oracle community 5.6 ? Has anyone else observed similar behavior? In our environment this observation is consistent and reproducible. Certainly moving to Oracle Mysql 5.6 is one solution, let me know if anyone has idea how to resolve this or how to investigate it further. (Tracing mysqld daemon has not given any clue.)

Hi,

I'm in the process of upgrading my MySQL Database server from a Windows 2003 server that runs MySQL 5.1 to a Windows 2012 server that runs MySQL 5.6 but I'm having problem with some queries running extremely slowly and I can't seem to locate the problem. The following applies:

- The new server has more memory and more processing power than the old one
- I've increased the size of the innodb_buffer_pool_size, innodb_log_file_size, innodb_log_buffer_size, query_cache_size, table_open_cache, tmp_table_size, myisam_sort_buffer_size, key_buffer_size to match or, in most cases, be greater than the old server.
- I've tried increasing join_buffer_size and sort_buffer_size but the query doesn't run any quicker
- I've set the innodb_data_home_dir, again with no improved results

When I run the query and view the Performance Dashboard in Workbench, this is what I see: LINK

Nothing in that suggests a problem to me, but the query is taking 300 seconds to run on the 2012 server, whereas on the 2003 (MySQL 5.1) server it takes 2 seconds. I've noticed that when I run an EXPLAIN on the query, the two servers give different outputs, but I don't understand enough about them to fix it. Here they are (I've hidden the table and ref columns for security reasons):

2003 server (fast): LINK
2012 server (slow): LINK

I especially feel the Primary/Derived select types may be the way to go whereas the new server all the select types are Simple.

So my question is, does anyone know why it may be taking so long? Will the select types have anything to do with it?

I've done a lot of searching online but haven't come across anything as yet. I did read that 5.6 can be a little slower than 5.1 for running queries but 300 seconds compared to 2 seconds means something is very wrong.

I would appreciate any help whatsoever.

Thanks.

I have been using various versions of MySQL over the past 4 years. The latest version that I've installed is 5.6 on Windows 7 Professional. Whereas in the past I usually didn't have too much of a problem creating a user that could connect from any client machine, on this latest instance I can't get it to work. I've tried creating the user using both the MySQL Workbench and by using a GRANT command at the command line. Nothing works. When I try to connect remotely using the MySQL Workbench I get the standard message saying "can't connect blah blah blah".

I've tried many variations of the GRANT command, I run "FLUSH PRIVILEGES", I've restarted the service, etc. etc.

If you have any advice it is very much appreciated!
