MySQL 5.6 Reference Manual Including MySQL NDB Cluster 7.3-7.4 Reference Guide
Program Database (PDB) files (with file name suffix
pdb
) are included in ZIP Archive
distributions (but not MSI distributions) of MySQL. These files
provide information for debugging your MySQL installation in the
event of a problem.
The PDB file contains more detailed information about
mysqld
and other tools that enables more
detailed trace and dump files to be created. You can use these
with WinDbg or Visual Studio to debug
mysqld.
For more information on PDB files, see Microsoft Knowledge Base Article 121366. For more information on the debugging options available, see Debugging Tools for Windows.
To use WinDbg, either install the full Windows Driver Kit (WDK) or install the standalone version.
The .exe
and .pdb
files must be an exact match (both version number and MySQL
server edition) or WinDBG complains while attempting to load
the symbols.
To generate a minidump mysqld.dmp
,
enable the core-file
option
under the [mysqld] section in my.ini
.
Restart the MySQL server after making these changes.
Create a directory to store the generated files, such as
c:\symbols
Determine the path to your windbg.exe
executable using the Find GUI or from the command line, for
example: dir /s /b windbg.exe
-- a common
default is C:\Program Files\Debugging Tools for
Windows (x64)\windbg.exe
Launch windbg.exe
giving it the paths
to mysqld-debug.exe
,
mysqld.pdb
,
mysqld.dmp
, and the source code.
Alternatively, pass in each path from the WinDbg GUI. For
example:
windbg.exe -i "C:\mysql-5.6.51-winx64\bin\"^ -z "C:\mysql-5.6.51-winx64\data\mysqld.dmp"^ -srcpath "E:\ade\mysql_archives\5.6\5.6.51\mysql-5.6.51"^ -y "C:\mysql-5.6.51-winx64\bin;SRV*c:\symbols*http://msdl.microsoft.com/download/symbols"^ -v -n -c "!analyze -vvvvv"
The ^
character and newline are removed
by the Windows command line processor, so be sure the
spaces remain intact.
