Question

How to import successfully into InfoSphere Information Governance Catalog (IGC) the glossary files delivered with IBM Industry Models

Cause

As IBM Industry Models delivers large glossary files, the configuration of InfoSphere Information Governance Catalog should be adapted for the import/export and the associated queries

Answer

Increase the time-out for InfoSphere Information Server and WebSphere, as documented with the following Technote http://www.ibm.com/support/docview.wss?uid=swg21621492

  1. For Information Governance Catalog domain server installed on Websphere Liberty Profile, increase the default Java Heap Size of WLP in the file /*install location*/wlp/usr/servers/iis/jvm.option by modifying the -Xmx2048m value to a higher value, for example -Xmx6144m.
  2. In IGC, disable the Term History for the import of the IBM Industry Models glossary xml. (The Term History can be enabled again once finished with the import). 
    Details are available from the following page:
    http://www.ibm.com/support/docview.wss?uid=swg21663894
  3. Update the following parameters with the "iisAdmin -set -key" command. The default location of the command is /opt/IBM/InformationServer/ASBServer/bin. 
    - com.ibm.iis.gov.importexport.minXMLSlicingWeight -value 20000
    - com.ibm.iis.gov.vr.setting.maxObjectsInMemory -value 5000000
    - com.ibm.iis.gov.vr.setting.maxRowsInSearchResultSheet -value 100000
    - com.ibm.iis.gov.vr.setting.maxObjectsPerRefInSearchResults -value 500
    - com.ibm.iis.gov.vr.setting.queryResultRecommendedBatchSize -value 50000
    - com.ibm.iis.gov.xFrameOptions -value SAMEORIGIN

    For example, to update the first parameter, run the following command:
    ./iisAdmin.sh -set -key com.ibm.iis.gov.importexport.minXMLSlicingWeight -value 20000

    After you finish updating the parameters, restart WebSphere
  4. Before each XML import, clean-up the Linkpoint

BLAFS is a bloat-aware filesystem for container debloating. The design principles of BLAFS are effective, efficient, and easy to use. It detects the files used by the container, and then debloats the container by removing the unused files. The debloated containers are still functional and can run the same workload as the original containers, but with a much smaller size and faster deployment. https://github.com/negativa-ai/BLAFS?tab=readme-ov-file
