Troubles with Embedded connection
Posted: Mon 11 Sep 2006 15:16
The problem is:
1. On the first connection using InnoDB engine database is successfully created (iblogfiles and ibdata).
2. When connecting for the second time (in next application run) this error occures 'A call to an mysql_server_init failed D:\data\ibdata1...'. The log contains this records:
060911 19:02:26 InnoDB: Operating system error number 0 in a file operation.
InnoDB: Some operating system error numbers are described at
InnoDB: hxxp://dev.mysql.com/doc/mysql/en/Operating_System_error_codes.html
InnoDB: File name D:\Data\ibdata1
InnoDB: File operation call: 'create'.
InnoDB: Cannot continue operation.
We've wrote analogous application in C-language (Open Watcom 1.3) using native MySQL API (mysql_server_init etc.) to test embedded server at all. It works... So, an error is not in mysql code.
We address our question to corelab team:
How can we get working version of MyDAC components. We need Exactly embedded connections.
Customer of MyDAC.
P.S.
Tested versions of MySQL Server are 4.1.7. and 4.1.18.
Version of MyDAC is last (downloaded yesterday).
