This directory contains all the scripts needed to upgrade from grib to the new
|
||
|
|
"Unified" grid storage format.
|
||
|
|
|
||
|
|
The following commands will need to run to upgrade postgres and hdf5 files:
|
||
|
|
bash register_grid_coverage.sh
|
||
|
|
bash create_grid_tables.sh
|
||
|
|
python convert_grib_data.py
|
||
|
|
|
||
|
|
The following commands will need to run to upgrade localization files:
|
||
|
|
bash copy_grib_purge_rules.sh
|
||
|
|
bash update_D2D_bundles.sh
|
||
|
|
bash update_D2D_procedures.sh
|
||
|
|
bash update_FFMP_Source.sh
|
||
|
|
|
||
|
|
convert_grib_data.py can take a significant amount of time, as much as 2 hours.
|
||
|
|
If you don't need your data and you want to upgrade faster you can purge all grib data.
|
||
|
|
If there is no grib data to convert there is no need to run convert_grib_data.py.
|
||
|
|
|
||
|
|
After convert_grib_data.py has run, it may not convert all models(perhaps skipping
|
||
|
|
alaskan, hawaiin, or other models.) If this is the case there will be data left over
|
||
|
|
in /awips2/edex/data/hdf5/grib. This data can be used if you need to convert additional
|
||
|
|
models or if a rollback is necessary. The system is not set up to purge this data, so
|
||
|
|
after a successful upgrade when new data is arriving this directory will need to be deleted.
|
||
|
|
|
||
|
|
The format of the data in /awips2/edex/data/hdf5/topo/modelStaticTopo.h5 has changed. When the
|
||
|
|
ingestGrib edex is started it will attempt to regenerate this file. This is a very time and
|
||
|
|
memory intensive process. To save time when upgrading an operational system it is recommended
|
||
|
|
that you copy a modelStaticTopo.h5 file from a testbed or other system that has already generated it.
|
||
|
|
|
||
|
|
The update_saved_display.sh script can be used if there are any saved displays that are
|
||
|
|
saved outside of localization.
|
||
|
|
|
||
|
|
If for some reason the upgrade fails or you want to roll back. Install an old
|
||
|
|
version of edex and run the scripts in the unified_grid_rollback directory.
|
||
|
|
The postgres and hdf5 scripts in that directory will need to be run in the opposite order:
|
||
|
|
python convert_grib_data.py
|
||
|
|
bash create_grid_tables.sh
|
||
|
|
bash register_grid_coverage.sh
