Hi Hsie,

Very good.

Me too. I don't understand why access to the database was lost after
the reboot this morning.

No, this is not correct. For instance, I am able to access the data in
the RTGRIBS dataset from stratus on my home machine:
<as 'yoksas' on my home machine>
cd $MCDATA
dataloc.k LIST RTGRIBS

Questions:
- what user were you when you ran this DSINFO command
- what is the output of:
dataloc.k LIST RTGRIBS
when you are the same user
I am betting that since RTGRIBS is a new dataset in v2007 that
your McIDAS-X session does not have a pointer to the external
ADDE interface on stratus for it. If this is the case, McIDAS assumes
that the dataset is LOCAL-DATA, and it is almost 100% sure that you
did not create the server mapping table entries as this user for
RTGRIBS.
Please NOTE: It is much better if your non-'mcidas' user points to
the external ADDE interface on stratus for all of the data that
stratus is serving. This is one of the reasons that I include
the creation of the LOCDATA.BAT file in the ~mcidas/data (~mcidas/solaris/data
on stratus) directory. If your non-'mcidas' user is setup the
way that is recommended in the Unidata McIDAS-X Users Guide, then
it should be able to access the files in the ~mcidas/data (again,
~mcidas/solaris/data on stratus) directory. The user can then make
the settings made in LOCDATA.BAT active as follows:
<as the non-'mcidas' user>
cd $MCDATA
batch.k LOCDATA.BAT CONTINUE=YES
The DATALOC commands contained in LOCDATA.BAT set the user's access
for the various datasets to the remote ADDE interface on the machines
where the various datasets are hosted:
DATALOC ADD CIMSS stratus.al.noaa.gov
DATALOC ADD GINICOMP stratus.al.noaa.gov
DATALOC ADD GINIEAST stratus.al.noaa.gov
DATALOC ADD GINIWEST stratus.al.noaa.gov
DATALOC ADD NEXRCOMP stratus.al.noaa.gov
DATALOC ADD RTGRIBS stratus.al.noaa.gov
DATALOC ADD RTGRIB2 stratus.al.noaa.gov
DATALOC ADD RTGRIDS adde.ucar.edu
DATALOC ADD RTIMAGES stratus.al.noaa.gov
DATALOC ADD RTNEXRAD stratus.al.noaa.gov
DATALOC ADD RTPTSRC stratus.al.noaa.gov
DATALOC ADD RTWXTEXT stratus.al.noaa.gov
DATALOC ADD TOPO stratus.al.noaa.gov
DATALOC ADD AMRC uwamrc.ssec.wisc.edu
DATALOC ADD EAST unidata2.ssec.wisc.edu
DATALOC ADD EUM_AD 193.17.10.4
DATALOC ADD GOESEAST unidata2.ssec.wisc.edu
DATALOC ADD ME7 io.sca.uqam.ca
DATALOC ADD PUB gp16.ssd.nesdis.noaa.gov
DATALOC ADD SOUTH goessouth.unidata.ucar.edu
DATALOC ADD WEST unidata2.ssec.wisc.edu
DATALOC ADD MYDATA LOCAL-DATA
DATALOC ADD BLIZZARD stratus.al.noaa.gov
After doing this your non-'mcidas' user should be able to access
all of the data that stratus is maing available in the same way
that I am able to access all of the data that stratus is making
available from my home and work machines.
Also note that there are several sites accessing data on stratus:
<as 'mcidas'>

Again, my home machine is bcn-204-144-179-235.mric.net. There is no entry
for my work machine since the SERVER.LOG file gets rotated on Saturday
night, and I have not accessed your machine from work since then.
Cheers,
Tom
