Informatica Identity Resolution v9.5.0 HF1 is a maintenance release containing a roll-up of hot fixes and usability enhancements.
Rulebase Server Group
Effective in version 9.5.0 HotFix1, use the rbsgdown utility to shut down Rulebase Servers running in a Rulebase Server Group. The rbsgdown utility automatically identifies the active Rulebase Server in the group and directs the shutdown command to it. Previously, an administrator would need to determine which Rulebase Server was active prior to executing the idsdown script.
Name3 Workbench User Interface
Effective in version 9.5.0 HotFix1, both the Name3 Workbench and Population Override Manager will accept input in both text and hexadecimal form and allow conversion between the two formats. This enhancement facilitates working with multi-byte and Unicode data in scripts such as Chinese, Japanese and Korean without the need to change input locale to enter data in its native character set. Previously, it was necessary to change the input locale to enter data in the native character set.
