This chapter describes how to use the Oracle Big Data Appliance Configuration Utility. It contains the following sections:
Note:
An Oracle representative typically completes the Oracle Big Data Appliance Configuration Utility from information provided by the customer in the Oracle Big Data Appliance Configuration Worksheets.The information entered in the Oracle Big Data Appliance Configuration Utility is used to generate the installation and deployment files. After you enter values into the utility, the information is validated. Then the utility generates the files for Oracle Big Data Appliance.
The utility is implemented as a spreadsheet containing these worksheets:
Welcome
Network Configuration
Software Configuration
Preview
This section explains how to use the Oracle Big Data Appliance Configuration Utility. It contains these topics:
You must use Apache OpenOffice Spreadsheet 3.4 or Oracle Open Office Calc 3.3 to configure the spreadsheet. Do not use other spreadsheet programs like Excel, which can modify the spreadsheet but not generate the files.
To obtain the Oracle Big Data Appliance Configuration Utility, refer to My Oracle Support Note 1434477.1.
To open the Oracle Big Data Appliance Configuration Utility:
Download OpenOffice from this website and follow the instructions for installing it:
Open Apache OpenOffice Spreadsheet.
From OpenOffice Spreadsheet, open the bda_configurator.ods file. If the current settings do not allow macros, you see a message.
To change the macro setting:
From the Tools menu, choose Options.
In the navigation tree, expand the OpenOffice.org folder and select Security.
In the right pane, click Macro Security.
Either lower the security level or enter a trusted source.
To turn off AutoCorrect:
From the Tools menu, choose AutoCorrect Options.
Select the Options tab.
Clear all check boxes, and then click OK.
AutoCorrect settings can make it difficult for you to enter passwords.
Save your changes and reload the spreadsheet.
If you see a security warning, select Enable Macros.
This procedure describes how to use the Oracle Big Data Appliance Configuration Utility to customize the default configuration settings for your installation. The other sections in this chapter provide detailed information about each field in the spreadsheet.
To generate the configuration files:
Open the spreadsheet with OpenOffice as described in the previous procedure. The Welcome sheet opens.
Click Next to edit the Network Configuration sheet.
Enter the network configuration settings as specified in the Oracle Big Data Appliance Configuration Worksheets.
Click Next. If your changes are invalid, then you see an error message. You must correct the errors before continuing to the Software Configuration sheet.
To discard your changes, click Reset.
Enter the software configuration settings as specified in the Oracle Big Data Appliance Configuration Worksheets.
Click Preview to view the configuration settings defined by your entries. To make any changes, either click Previous or click the tab for a particular sheet. You must click Preview on the Software Configuration sheet for the changes to appear on the Preview sheet.
When you are satisfied with the configuration, click Save Configuration on the Preview sheet to generate the configuration files.
This step does not save the worksheet. To save your changes, click the Save icon.
Choose a location for the configuration files in the Select Path dialog box. The files are created in a directory named bda-customer_name/rack_name in that location, such as bda-Example Inc/bda1.
If you are configuring multiple racks as a single CDH cluster, then you are done. Otherwise, generate separate configuration files for every set of racks that will be configured as a single CDH cluster.
Provide the network administrators and others at the site with a copy of the Configuration Templates to verify that the configuration is correct.
The Oracle Big Data Appliance Configuration Utility generates the following files to use when you configure the system.
Runs a series of tests to ensure the specified names and IP addresses for Oracle Big Data Appliance were added correctly to the name server and they do not conflict with the existing network configuration. See "Checking for Network Errors" for instructions on running this script.
Contains the network configuration. Transfer this file to a USB drive for copying to Oracle Big Data Appliance. See "Configuring the Network".
Contains all information provided in the spreadsheet, including the network configuration, port numbers, default user names, and passwords. Transfer this file to a USB drive for copying to Oracle Big Data Appliance. See "Using the Mammoth Utility".
Reproduces the Installation Preview page of the spreadsheet in a printable format. The network administrator and others can use this Installation Template to verify the settings and make any last minute corrections.
Figure 4-1 shows part of the first page of the Installation Template.
The network administrator must add the host names and IP addresses for the components of Oracle Big Data Appliance to a name server. When this task is complete, you can use the preinstall-checkip.sh script to check the network for errors.
Run the preinstall-checkip.sh script at these points in the installation process:
Before Oracle Big Data Appliance arrives at the site but after the network administrator has added the new names and IP addresses to the name server. This step ensures that the network configuration parameters are valid and the network is ready to accept Oracle Big Data Appliance connections.
After Oracle Big Data Appliance arrives but before it is connected to the network. This step ensures that the network has not changed and is still ready to accept Oracle Big Data Appliance connections.
To check the network for conflicts:
Copy the preinstall-checkip.sh script to any Linux system with a 10 GB Ethernet connection to the subnet on which Oracle Big Data Appliance will be deployed.
Ensure that the script is executable:
chmod +x preinstall-checkip.sh
Execute the script:
./preinstall-checkip.sh
If the script identifies errors, open the bda-checkip.out file for details. It contains information about every test the script performed. The output file is created in the same directory as the script.
Resolve the conflicts if possible before proceeding.
If you are unable to resolve all IP address conflicts between the existing network and Oracle Big Data Appliance, then you can proceed without connecting to the network up to "Configuring the Network". The procedures take longer to complete because of time-outs from attempts to connect to configured services such as Domain Name System (DNS) and Network Time Protocol (NTP).
Example 4-1 shows success and error messages from the preinstall-checkip.sh script.
