[McIDAS #HZP-657281]: Moving McIDAS-XCD server



Hi Hsie,

re: remake MySQL database on stratus

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

Group Name                    Server IP Address
--------------------         ----------------------------------------
RTGRIBS                      STRATUS.AL.NOAA.GOV

<LOCAL-DATA> indicates that data will be accessed from the local data directory.

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'>

-----------------+-----------+--------------------------------
All                 4.42D+08    1270
ADDEINFO: Done

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
