The harvest database need to be updated before starting NetarchiveSuite 4.2 the first time using the HarvestdatabaseUpdateApplication program. Information on how to do that can be found in the additional tools manual under Harvester tools. If you don't do it, the following two applications will not start: GUIApplication and HarvestJobManagerApplication .
Table 'jobs' moves from version: 8 to 9 with the following change:
ALTER TABLE jobs ADD COLUMN harvestname_prefix VARCHAR(100) DEFAULT NULL
Table 'harvestdefinitions' moves from version: 2 to 3 with the following change:
ALTER TABLE harvestdefinitions ADD COLUMN audience VARCHAR(100) DEFAULT NULL
The choice between asking Heritrix to writer ARC of WARC files is now a system-wide decision
In 4.0, this choice was made on the harvest-machines. Now this choice is performed in the HarvestJobManager when creating the harvestjob. The decision is made by reading the setting harvester.harvesting.heritrix.archiveFormat. The choice of metadataformat is still decided by the value of harvester.harvesting.metadata.metadataFormat on the harvestmachines. But ofcourse the supported way is to use the same metatadataFormat for all harvests.
