Thanks wlad for explanation, but this applies to 'shortcuts' (in start menu) only I think, as I understand your reply. If I navigate ('cd ..') to the /datadir where my.ini resides and launch 'mysql' from commnd line I will need to specify --defaults-file on the command line, right? If not the client will start with defaults (or it will use whatever other my.ini it finds in C:\, C:\Windows or /basedir). ? -- Peter On Fri, Sep 27, 2013 at 7:06 PM, Vladislav Vaintroub <wlad@montyprogram.com>wrote:

"I rarely find myself in need to use my.ini for clients". Not me either except for max_allowed_packet (what is implemented in both server and client) that user want to set to INSERT table rows with photographs (.jpg's typically) to a table. And the 'mysql' command line client has a default max_allowed_packet of 1MB (in the server it was raised to 4MB in MySQL 5.6 - and if I remember right it is 8MB in recent MariaDB - but I belive the client setting is still 1MB even in MySQL 5.6 - I have not checked though). In contrast the C-API (both Oracle's and MariaDB's) has a defaut of 1GB (not sure about other connectors - such as JAVA and .NET). But I am not aware of any GUI client compiling/linking the connector with client max_allowed_packet lowered from 1GB (the highest possible value the protocol allows for currently). -- Peter On Fri, Sep 27, 2013 at 8:19 PM, Vladislav Vaintroub <wlad@montyprogram.com>wrote:

Justin, I appreciate your opinion, and if MySQL on Windows would not support multiple versions running on the same machine, I would agree. But since we (and/or generations of programmers before me) chose to support multiple version of MySQL coexisting on the same machine, and I did not want to break it, I see no real alternative.

It is just that in the case of VS you might cross-compile or choose to compile with Vs2008 or vs2012 as they can be installed simultaneously. I think if you are creating a service (in windows parlance) the client should know how to connect to the service sans hoops. Just my opinion... VS is not the way most windows programs do things and you should not violate the principal if least surprise. --Justin On Sep 27, 2013, at 1:06 PM, "Vladislav Vaintroub" <wlad@montyprogram.com> wrote: The command line clients are not services, and they are not started with --defaults-file, this is correct.

On Windows multiple MySQL servers run (if only they have distinct basedir, datadir, port (and/or pipe) and service name). This is how Windows manages servides (daemons) simply!

And BTW: this is the reason why Windows is a comfortable platform for application testing if you want to test an application that should work with multiple MySQL server versions. Multiple MySQL servers on *nix is a PITA - on Windows it is an ease as the OS has no restriction in this respect

on Linux also, with systemd like below, yes i had also running multiple MySQL instances before systemd, now it takes 5 minutes and a new instance is running and the rpm-build-process is straight forwared, see the third one which is MySQL while the other both are MariaDB [root@testserver:~]$ cat /usr/lib/systemd/system/mysqld.service [Unit] Description=MariaDB Database Before=network.service [Service] Type=simple ExecStart=/usr/libexec/mysqld --defaults-file=/etc/my.cnf --user=mysql ExecStartPost=/usr/libexec/mysqld-wait-ready $MAINPID Restart=always RestartSec=1 TimeoutSec=300 OOMScoreAdjust=-1000 PrivateTmp=true CapabilityBoundingSet=~CAP_SYS_PTRACE [Install] WantedBy=multi-user.target [root@testserver:~]$ cat /usr/lib/systemd/system/mysqld-dbmail.service [Unit] Description=MariaDB DBMail-Database Before=postfix.service dovecot.service dbmail-imapd.service dbmail-lmtpd.service dbmail-pop3d.service [Service] Type=simple ExecStart=/usr/libexec/mysqld --defaults-file=/etc/my-dbmail.cnf --user=mysql ExecStartPost=/usr/libexec/mysqld-dbmail-wait-ready $MAINPID Restart=always RestartSec=1 TimeoutSec=300 OOMScoreAdjust=-1000 PrivateTmp=true CapabilityBoundingSet=~CAP_SYS_PTRACE [Install] WantedBy=multi-user.target [root@testserver:~]$ cat /usr/lib/systemd/system/mysqld-oracle.service [Unit] Description=MySQL DBMail-Database (Oracle) Before=postfix.service dovecot.service dbmail-imapd.service dbmail-lmtpd.service dbmail-pop3d.service [Service] Type=simple ExecStart=/usr/local/oracle/libexec/mysqld --defaults-file=/etc/my-oracle.cnf --user=mysql Restart=always RestartSec=1 TimeoutSec=300 OOMScoreAdjust=-1000 SysVStartPriority=64 PrivateTmp=true CapabilityBoundingSet=~CAP_SYS_PTRACE [Install] WantedBy=multi-user.target
