Before you restore the Data Warehouse database, you should increase the Java allocation for Cognos from 768 MB to 2048 MB to decrease report generation time.

Steps

  1. Open a command prompt window as administrator on the Data Warehouse server.

  2. Navigate to the disk drive:\install directory\SANscreen\cognos\c10_64\bin64 directory.

  3. Type the following command: cogconfigw

    The IBM Cognos Configuration window displays.

    Note

    The IBM Cognos Configuration shortcut application points to disk drive:\Program Files\SANscreen\cognos\c10_64\bin64\cognosconfigw.bat. If Insight is installed in the Program Files (space between) directory, which is the default, instead of ProgramFiles (no space), the .bat file will not work. If this occurs, right click the application shortcut and change cognosconfigw.bat to cognosconfig.exe to fix the shortcut.

  4. From the navigation pane on the left, expand Environment, expand IBM Cognos services, and then click IBM Cognos.

  5. Select Maximum memory for Tomcat in MB and change 768 MB to 2048 MB.

  6. On the IBM Cognos Configuration toolbar, click cognos save icon(Save).

    An informational message displays to inform you of the tasks Cognos is performing.

  7. Click Close.

  8. On the IBM Cognos Configuration toolbar, click cognos stop icon(Stop).

  9. On the IBM Cognos Configuration toolbar, click cognos start icon(Start).
