Hi Hsie,

re: 
> I reboot the machine this morning.

I noticed.  I was logged on to stratus trying to investigate a problem I
found that is affecting the writing of GRIB messages to disk.  This problem
is being seen on stratus, but not on other systems that I have access to
including 64-bit Linux and 32-bit Solaris SPARC.

I just logged onto stratus and tried to run 'gribadmin num'.  Here is the 
result:

stratus:[54]% gribadmin num
ERROR 1044 (42000): Access denied for user ''@'localhost' to database 'mcrtgrib'

ERROR 1044 (42000): Access denied for user ''@'localhost' to database 'mcrtgrib'
  Model Number   % of 
  Name  of Grids Total
  ===== ======== =====
  ----- -------- -----
  Total         

I tried deleting the MySQL database, but this also failed in the same way:
stratus:[55]% gribadmin removedb
Enter password: 
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: 
YES)


The only time I have seen messages like this was when the password for the MySQL
database was incorrect.  It seems to me that we are seeing this situation now
on stratus.

So, I suggest resetting the password for the MySQL database; this needs to be
done as 'root'.

Here are a couple of references that show how to change the MySQL password:

http://www.mydigitallife.info/2006/06/06/change-and-reset-mysql-root-password/

After the password has been reset, I think that it would be wise to delete and
remake the database:

<as 'mcidas'>
cd $MCDATA
decinfo.k SET DMBIN INACTIVE
-- wait until DMBIN has exited
gribadmin removedb
gribadmin makedb
decinfo.k SET DMBIN ACTIVE

Cheers,

Tom
