5.1.1 - patch release - 2019/02/28

dfdiscover-sp511.tar (2.5 MB)

This change corrects a bug in DFedcservice. In the specific case where a record with a level of 2 or higher is being saved back to level 1, it is possible for query records updated via the API to not save the new or updated text of a query reply.
The correction is available as a server-side patch. The patch is released as a tar image that contains DFedcservice only.
To install the patch:
  1. Download the tar image for the patch to /tmp. Then as super-user:
  2. # cd /opt/dfdiscover
  3. # tar xf /tmp/dfdiscover-sp511.tar
  4. # /opt/dfdiscover/SETPERMS

The patch can be installed on a live system. There is no requirement to restart the DFdiscover server.

DFws API Resources

The DFws API is available for customer application implementation.

Use of DFws requires:

  • a DFdiscover server that has the DFWS feature enabled in the license,
  • a unique set of DFWS credentials,
  • an optional DFws server.
