About Semantic Graph Index Specificities

This page explains which files to prepare to install Semantic Graph Index Application Server and ENOVIA Studio Modeling.

This page discusses:

Pre-requisites

A Semantic Graph Index platform with the same version level must be installed with:

  • A valid license file for a standalone installation
  • The latest cumulative hotfix
Note: No configuration change should have been made on your Business Analytics Server installation. For more information about the platform installation, see Installation and Setup: Install: Information Intelligence: Business Analytics Server.

Sizing

Example of hardware sizing hypothesis:

  • <1 million Business Objects collected, containing textual data (alphanum / dates/ numbers)
  • <2 full re indexing of data per day
  • <1 query / second on search traffic peak , latency < 1 second

Corresponding hardware recommendation:

  • CPU: 4 core
  • RAM: 16 Go
  • Disk: 300 GB - with speed >1000 iops in random access read & write - 30MB/s in sequential throughput

Files to Prepare

You must install Semantic Graph Index Application Server and ENOVIA Studio Modeling on the same physical server.

You should prepare in a directory the following files:

  • The license file for Semantic Graph Index (.dat), that you should get from your NETVIBES sales representative.
  • The DSLS file that contains the DSLS servers specifications (.txt).
  • The certificate of the 3DSpace fcs (.cer). On Linux, check that your system fits the general requirements. Three topics have to be carefully checked:
    • the supported platform (redhat, .. Version)
    • the ulimit (nbproc for your user, ..)
    • the dependencies package (using yum / yast)
  • FCS URLs are available at two different locations. They can be retrieved in mql using:
    • the following command line path /home/data/RTV/server name/EVT/store/EVT/STORE or path /home/data/RTV/server name/server/store
    • a Chrome web browser with a direct access to the server. To view the certificate, you need to click on the Details hyperlink. Then you copy the file with the .cer format.

Notes:
  • Semantic Graph Index indexes the 3DSpace data.
  • ENOVIA Studio Modeling makes a link between the 3DSpace server and Semantic Graph Index .
  • By default, the Semantic Graph Index server is configured to do an incremental scan every three minutes.
    Tip: Modify the periodic scheduling on ENOVIA ER connectors in Semantic Graph Index so that the index does an incremental scan (every two minutes for example).
