Re: Installing MySQL on Windows Server 2003 Standard x64 Edition
I didn't add it anywhere because the file exists in mysql/bin folder c:/program files/mysql/bin Does it need to be somewhere else??

Installing MySQL on Windows Server 2003 Standard x64 Edition
I'm having problems with MySQLInstanceConfig.exe - Unable To Locate Component This application has failed to start because LIBMYSQL.dll was not found. Re-installing the application may fix this problem I have tried to re-install, but I get the same message. I read the following related threads but didn't help. http://lists.mysql.com/win32/14799 http://lists.mysql.com/mysql/167676 I looked for the file and it exists in: /mysql/bin/ /mysql/lib/debug/ /mysql/lib/opt/ This is the download I'm using for the installation: Windows Server 2003 (AMD64 / Intel EM64T)5.0.24 Please advise.

Windows Server Configuration
We want to get: Windows Server 2003 R2, Standard x64 Edition 2- Dual Core Intel Xeon 5080, 2x2MB Cache, 3.73GHz, 1066MHz FSB 8GB 533MHz (8x1GB), Dual Ranked DIMMs 3- 146GB, SAS, 3.5-inch, 15K RPM Hard Drives What would be the recommended RAID configuration settings for a dedicated MySQL db running on this system? Also, what is the general advice for separating MySQL and the MySQL/Data on different disks? I'm sorry if this sort of question has already been answered. Any help would be appreciated.
