'dump -Tv' command.

It seems that you try to start a 64bit DB2 instance. Is your OS actually running in 64bit and/or do you have a 64bit version of /usr/lib/threads/libc installed?

I also recommend that you follow the hint in the error message and run "dump -Tv /usr/lib/threads/libc.a".

this is the output, but i dont know how to interpret this one. we are using 64bit.

/usr/lib/threads/libc.a[aio.o]:

Hi,

the issue is with assynchronous I/O . .i set it to available. then restart the server.. everything works now .
