[McIDAS #DXX-994121]: MDXX mishaps

Hi Paul,

I don't quite understand why you removed MDXX0001.

Hmm... very strange.

I think that it may be a bit of both.

Here is what I recommend doing (note that the following is brute force):

<as 'ldm'>
ldmadmin stop

<as 'mcidas'>

cd $MCDATA
rm DCLSTIDX.PTR *.ERR *.IDM
tl.k XCDDATA          <- remind yourself of where the decoders will write their 
output,
                         for the purpose of illustration, let's assume that the 
output
                         directory is /data/ldm/mcidas

cd /data/ldm/mcidas
rm IDXALIAS.DAT *.IDX *.RAP *.RAT *.XCD
rm MDXX<the file for the current Julian day>

cd $MCDATA
dmap.k ROUTE.SYS      <- should point to /data/ldm/mcidas AND read/write mode 
should be 664
dmap.k SYSKEY.TAB     <- should point to /data/ldm/mcidas AND read/write mode 
should be 664
dmap.k SCHEMA         <- should point to /data/ldm/mcidas AND read/write mode 
should be 664

                         NOTE:
                         - the dmap.k is done to make sure that your McIDAS 
setup is pointing
                           to a copy in /data/ldm/mcidas

                         - the file permissions on ROUTE.SYS, SYSKEY.TAB, and 
SCHEMA
                           need to be such that both 'mcidas' and 'ldm' can 
read/write the files!

                         - SYSKEY.TAB should be 24000 bytes in size

route.k LIST          <- make sure that you get a good listing

cp ../data/SCHEMA /data/ldm/mcidas       <- check the read/write mode of SCHEMA

decinfo.k LIST        <- make sure that the decoders you want to run are listed 
as being active
batch.k XCD.BAT
batch.k XCDDEC.BAT    <- after running this you should have files in 
/data/ldm/mcidas with the
                         .RAP

<as 'ldm'>
ldmadmin start

Again, the procedure above is heavy weight -- it forces everything to start 
anew.

Please let me know if this helped.

Cheers,

Tom
