Failed to load libaio

Re: Failed to load libaio

could you post the output of

rpm -qa | grep aio

Ensure you just have single aio package (64 bit only )

Re: Failed to load libaio

is the directory where the lib lives in the current path of the user
running db2start?

Here it is:

rpm -qa | grep aio
libaio-devel-0.3.105-2
libaio-0.3.105-2

It doesn't say anywhere that it's 64-bit but, the following seems to
indicate it is:

ls /usr/lib64/libaio*
/usr/lib64/libaio.a /usr/lib64/libaio.so

Now there are other libaio files in /usr/lib:

ls -lrt /usr/lib/libaio*
-rwxr-xr-x 1 root root 2628 Sep 16 2005 /usr/lib/libaio.so.1.0.1
-rwxr-xr-x 1 root root 2632 Sep 16 2005 /usr/lib/libaio.so.1.0.0
lrwxrwxrwx 1 root root 15 Mar 19 15:26 /usr/lib/libaio.so.1 ->
libaio.so.1.0.1

Is this what I should see if I have the 64-bit version installed? My
sysadmin says it was the 64-bit version.
Should I question him further?

Tried it both in the PATH and in the LD_LIBRARY_PATH . Didn't seem to
make a difference.
