IM InfoSphere Identity Insight, Version 8.0

Migrating to the upgraded IBM Global Name Recognition Name Hasher

If your product used the Name Hasher prior to product version 8.0 fix pack 2, complete these tasks in addition to the standard tasks required to upgrade to the latest Name Hasher functionality.

Procedure

  1. Perform the standard product upgrade using the product installation program.
  2. In the Configuration Console, disable DQM function 660 on the UMF <NAME> segment. Copy or write down the current values for the maxVariants and variantScoreThreshold parameters contained with the HTTP URL parameter. Prior to product version 8.0 fix pack 2, enhanced name hashing functionality used a Name Hasher servlet that ran on a web application server. In product version 8.0 fix pack 2 and later, the Name Hasher functionality is built into the pipeline. By disabling DQM function 660 on the <NAME> segment, you disable the existing Name Hasher servlet.
  3. In the Configuration Console, enable ../../../com.ibm.issi.ii.reference.doc/topics/eas_ref_dqmrule282.html (Name hash variants) on the UMF <NAME> segment and paste or manually configure the following function parameter values:
    maxVariants
    Set this value to the same value previously used on the DQM function 660 maxVariants parameter.
    variantScoreThreshold
    Set this value to the same value previously used on the DQM function 660 variantScoreThreshold parameter
    Note: If the DQM function 660 does not contain values for these parameters in the URL, use the DQM function 282 default values.
    By completing this step, you activate the Name Hasher functionality within the pipeline.
  4. In the Configuration Console, configure the system parameters for the Name Hasher. By completing this step, you globally configure the necessary parameters that the pipeline uses as part of the Name Hasher functionality.
