anchor command

The anchor command performs a one-off anchoring of selected database rows to the blockchain specified in the configuration file.

Usage

% provendb-oracle anchor --help
Anchor one or more tables to the blockchain.

USAGE
  $ provendb-oracle anchor

OPTIONS
  -v, --verbose        increased logging verbosity
  --config=config      config file location
  --includeRowIds      Include proofs for every row in the proof file
  --includeScn         Include SCN into rowid signature (create historical proof)
  --tables=tables      (required) tables to anchor
  --validate=validate  Validate the proof and output to file
  --where=where        WHERE clause to filter rows

DESCRIPTION
  Anchor reads the current state of selected table, filtered by an options WHERE
  clause.  Rows are hashed and anchored to the blockchain.

Arguments

Argument	Descriptionthough
--config	Configuration file which contains Oracle and provend DB configuration see Configuration file Reference
--includeRowIds	If the `validate` option is specified, include a proof for each row in the output
--includeScn	Create signatures for the rows concerned at the current System Change Number. This option assumes that Flashback queries are enabled. See System Change Numbers and Flashback Query
--tables=tables	Table(s) that are to be anchored. This argument can be specified multiple times to anchor multiple tables.
--validate=validate	After creating the proof, immediately validate the proof and create a proof file.
--where=where	WHERE clause to be applied to each of the tables being anchored.

Example

% provendb-oracle anchor --tables=PROVENDBDEMO.CONTRACTSTABLE --where=CONTRACTID=1 --validate=contract1.proof --includeRowIds --includeScn
