IBM GNR Integration
Release 11g R1 (220.127.116.11)
Oracle Enterprise Data Quality (EDQ) can be configured to connect to IBM Global Name Recognition (GNR).
GNR allows EDQ to perform linguistic analysis of names, and linguistically sensitive name searching.
GNR can only be installed on an EDQ instance if you have the required license agreements with both Oracle and IBM.
This document is intended for systems administrators responsible for installing and configuring EDQ applications.
The prerequisites for enabling EDQ GNR connectivity are:
EDQ version 9.0.4 or later, installed on 64-bit AIX or Linux running 64-bit Java.
GNR 4.2.1 (4.2 + 4.2.1 fixpack) or later, including the hotfix based on GNR 4.2.2 (4.2 +4.2.2 fixpack).
EDQ does not make use of any of the web services provided by GNR, so you do not need to configure these during GNR installation.
To integrate IBM GNR into EDQ, you perform these tasks:
LD_LIBRARY_PATH must be set as required for the installation environment.
The EDQ GNR analytic processors use a shared library (
.so) in the
lib64 directory of the GNR installation. This directory must be specified in an environment variable passed to the EDQ application server.
In a Linux 64-bit environment, the environment variable is
LD_LIBRARY_PATH; for example:
gnr-installation-dir is the GNR installation path; for example,
In an AIX environment, the environment variable name is
LIBPATH instead of
The environment variable must be available to the application server process.
The GNR Search Processor uses a native library that must be linked with the GNR libraries.
Oracle supplies these files to create the library:
Makefile templates, one for each platform, that script the building of the search library
namehunter.o object module file
When building the library on an AIX system, IBM C++ must be available. When building the library on Linux systems, the GCC C++ compiler must be available and it must be of the same version used to create the GNR libraries, as specified in the IBM GNR documentation.
Makefile template for 64-bit AIX is as follows:
# Build library from object file # ------------------------------ GNR=/opt/GNR/GNM CFLAGS=-qmkshrobj LIBS=-lNameHunter -lNameTransliterator -lsicui18n -lsicuuc -lsicudata SDK=aix61_64-xlc9-release LIBDIRS=-L$(GNR)/sdk/$(SDK)/lib -L$(GNR)/sdk/icu4c/$(SDK)/lib all: libnimrod.so libnimrod.so: namehunter.o xlc++_r -q64 $(CFLAGS) -o $@ $? $(LIBDIRS) -lNameHunter -lNameTransliterator -lsicui18n -lsicuuc -lsicudata
Makefile template for 64-bit Linux is as follows:
# Build 64-bit library from object file # -------------------------------------- GNR=/opt/GNR/GNM CFLAGS=-shared -fPIC all: libnimrod.so libnimrod.so: namehunter.o g++ -m64 $(CFLAGS) -o $@ $? -L$(GNR)/sdk/rhel4_64-gcc34-release/lib -L$(GNR)/sdk/icu4c/rhel4_64-gcc34-release/lib -lNameHunter -lNameTransliterator -lsicui18n -lsicuuc -lsicudata
Before running the
Makefile script for your platform, ensure that the value of
GNR in the
Makefile template is set correctly, according to the GNR installation directory location. On the AIX platform, also ensure that the value of
SDK is set correctly, according to the system architecture.
After running the edited
Makefile, the newly created
libnimrod.so shared library file can be installed anywhere and can be copied to other systems with GNR installs.
The EDQ GNR connector requires three types of configuration files to integrate it with GNR:
gnr.properties properties file in the EDQ installation
nameworks.config configuration file in the GNR installation
Search configuration files in the EDQ installation
gnr.properties file must be manually created and placed in the
gnr subdirectory of the EDQ configuration directory. It must contain the following properties:
The GNR installation path. This is the path to the directory containing the following GNR subdirectories:
data (which contains the GNR data files)
The absolute location of the
nameworks.config configuration file in the GNR installation.
The absolute location of the
libnimrod.so shared library, which was built using the
During GNR installation, a
nameworks.config file is created and stored in the GNR
The critical part of the
nameworks.config file is the reference files section:
[Reference Files] NameSifter=/opt/GNR/GNM/data/SifterRules.ibm
NameSifter value must refer to the
SifterRules.ibm file in the GNR installation.
Search configuration files are located in the
gnr/search subdirectory of the EDQ configuration directory. They are read by the connector and used to set parameters for the Search function.
A sample search configuration file named
search.config is available in the
support/data/search subdirectory of the EDQ installation. To create a search configuration file, copy this sample file to the
gnr/search subdirectory of the EDQ configuration directory and edit the copy to suit your needs.
The search configuration format changed slightly from GNR 3.2 to GNR 4.2, and the EDQ GNR connector supports both versions as far as possible. It also processes data for Organization searches.
The basic differences between the search configuration files in GNR 3.2 and GNR 4.2 are:
GNR 4.2 specifies the parameter files (taqs, variants, etc) in the
[hunter] section. GNR 3.2 uses the
[search] section. The EDQ GNR connector looks in the
[hunter] section first then the
The tag and variant files in GNR 4.2 are specified by keys such as
custTaqFile. In GNR 3.2, just
taqFile is used. The EDQ GNR connector looks for
custTaqFile and loads each if found. The same rules are used for variant and terms files.
The generic reg file is set by a specific
genericRegFile setting; in GNR 3.2 this always defaults to the
anglo reg file.
Some settings have been added to the
[parms] sections, and others have been removed.
