After you create and populate your
staging tables and write your ingestion mappings,
the final part of the process is to run the
command to validate your work.
When you instruct the Information Store to
ingest the data that you loaded into the staging
tables, you do it one ingestion mapping (and one
staging table) at a time. The i2 Analyze
deployment toolkit and the ETL toolkit both have a
command for validating your staging tables and a
particular ingestion mapping in a particular
mapping file.
The procedure for instructing the Information
Store to ingest your data is similar to many
others in this process. You start with one type or
one staging table, and build from there.
- Choose an entity staging table that you
populated with data and provided with an ingestion
mapping.
-
Run the
ingestInformationStoreRecords
command in
VALIDATE mode.
For example:
setup -t ingestInformationStoreRecords -p importMappingsFile=mapping.xml
-p importMappingId=Person -p importMode=VALIDATE
When you specify
importMode
and set it to
VALIDATE, the
command checks the validity of the specified
mapping, but no ingestion takes place. For more
information about the running the command and any
arguments, see
The ingestInformationStoreRecords task.
The output to
the console indicates whether the mapping you
identified is valid, provides guidance when it is
not valid, and gives a full list of column
mappings. The command sends the same information
to a log file that you can find at
toolkit\configuration\logs\importer\i2_Importer.log.
- Complete this validation step for each
staging table and ingestion mapping that you plan
to use.
The ingestion process for links verifies that
the entities at each end of the link are already
ingested. If it fails to find them, the process
fails. When you are developing your ingestion
process, ingest a small amount of entity data
before you validate your links.
Correct any problems in the ingestion
mappings file (or any ingestion properties file
that you specified) before you proceed to Adding data to the Information Store.
