I used Mono+System.Data.OracleClient+instantclient to access Oracle database in multi-threading way on x64bit SUSE Linux.
Your reply will be highly appreciated! My program run several minutes and crashed and exited with following message: Stacktrace: Native stacktrace: mono(mono_handle_native_sigsegv+0xb0) [0x48c230] mono(mono_arch_handle_altstack_exception+0xf5) [0x4bbf55] /lib64/libpthread.so.0 [0x2aed9a374c10] /opt/oracle/oradb/home/lib/libclntsh.so(kpcsncharset2ucs2+0x2b) [0x2aaaac9788e3] /opt/oracle/oradb/home/lib/libclntsh.so(OCICharSetToUnicode+0x9) [0x2aaaac8a6a93] [0x40adf508] Debug info from gdb: Using host libthread_db library "/lib64/libthread_db.so.1".

Hello,

This is an example of a self-contained test program that creates the required tables/records apart from the actual code that reproduces a bug. For any database related bug, a sample program of this sort will help in quickly finding a solution. (Ibrahim, in his first mail, had sent a code fragment instead of a fully-runnable test program.)

After I revised my code to provide test program, I cannot to repro this bug any more. Thanks for your instant support, which makes me more confident to use Mono widely in my project.
I love this cute mono. On Wed, Nov 4, 2009 at 4:14 AM, Miguel de Icaza <miguel@...> wrote: Hello, -- Best Wishes, 马智 _______________________________________________ Mono-list maillist - Mono-list@... http://lists.ximian.com/mailman/listinfo/mono-list |
