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
- Perform the standard product upgrade using the product
installation program.
- 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.
- 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.
- 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.
