2 Prepare the application server

• Required privileges for the database server
  You must have access to a user account that allows the user to start and stop the Oracle database.
• Required privileges for the application server
  You must have access to the following accounts on the application server:
• Set the default file creation umask
  You modify the default file creation umask so that, by default, users in your group have read-only access to files you create. Users outside your group have no access to the files you create.
• Unpack the installation files into the installation directory
  The installation directory stores Oracle Empirica Signal components during the installation process.
• Add the database TNSNAMES entry
  You add an entry to the tnsnames.ora file on the application server to configure the connection to the Oracle database.
• Set up the application database account (installation only)
  Perform these steps using the non-privileged user account on the application server.
• Set up the Topic Workflow database account (optional, installation only)
  You create a Topic Workflow tablespace and user account to enable the Oracle Empirica Topics feature.
• Set up the test data database account (installation only)
  This procedure is optional and needed only if you plan to run the OQ test.
• Apply upgrade scripts to Oracle Empirica Signal 9.1.x schemas (upgrade only)
  Schema upgrade is incremental. If you are upgrading from a version prior to Signal 9.2.3.x, multiple scripts need to be executed.
• Upgrade Signal Management configuration schemas
  Upgrade these configuration schemas.
• Install MGPS
  Install the MGPS program that supports Multi-item Gamma Poisson Shrinker (MGPS) data mining. For more information, see the User Guide and Online Help.
• Install or upgrade the RGPS add-on package to the R library
  If you have R version 4.4.1 installed, you can optionally install the RGPS add-on package to enable Regression-adjusted Gamma Poisson Shrinker (RGPS) computations in Multi-item Gamma Poisson Shrinker (MGPS) data mining runs.
• Install and configure the X Windows Virtual Frame Buffer (Xvfb) (new installation)
  You install X Windows Virtual Frame Buffer (Xvfb) to enable graphs in Oracle Empirica Signal.
• Modify the default Oracle WebLogic Server configuration files
  Perform these steps using the non-privileged user account on the application server.
