How to Install a Second Data Flow Probe on a Windows Machine

Notes before you install

• Supported combination: An existing Probe (of any version, separate or union mode) on Windows + a second Probe (of version 10.30 or later, union mode), reporting to two different UCMDB Servers

  That is to say, when installing a second Probe, you can

  • install it on Windows machine only
  • install a union mode Probe only
  • ignore the version of the existing Probe, as two Probes report to two different UCMDB servers

• On the same Windows machine, you can have two Probes at most.

  Even if you run the Data Flow Probe installer once again in an attempt to install a third Probe, it just overrides the second Probe.

• Multi network card is not supported
• You can change the ports manually after the installation.

The following procedure explains how to install a second Data Flow Probe on a Windows machine.

To install a second Data Flow Probe:

1. Insert the UCMDB10.33WIN DVD into the drive from which you are installing the Probe. If you are installing from a network drive, connect to the drive.

2. In the root folder of the DVD, double-click UCMDB_DataFlowProbe_10.33.exe.

3. A progress bar is displayed. After the initial process is complete, the splash screen opens. Choose the locale language and click OK.

4. The Introduction page opens. A prompt pops up reminding you that an existing Data Flow Probe installation is detected, and asking you if you would like to install a second Data Flow Probe. Click Yes to proceed, or click Cancel to cancel the installation.

5. The License Agreement page opens.

   Accept the terms of the end-user license agreement and click Next.

6. The Setup Type page opens.

   Select Full Data Flow Probe installation. This installs the Data Flow Probe with all its components, including the Inventory Tools (Analysis Workbench, Viewer, SAI Editor, and MSI Scanner) required for application teaching.

   Note The Inventory Tools option is used to install only the Inventory Tools. For details about application teaching, see the Universal CMDB Data Flow Management Guide.

   Click Next.

7. The Select Installation Type page opens.

   Select New Installation if you are installing a new probe.

   Note Select Upgrade when you upgrade an existing probe.

8. The Select Installation Folder page opens.

   Specify a different installation folder or click Choose to select a different installation folder for the second probe.

   Note The installation folder that you select must be empty.

9. The UCMDB Data Flow Probe Configuration page opens, enabling you to configure the details of the application server to which the second Data Flow Probe will report.

   • Under Application to report to select Universal CMDB and in the Application Server address box, enter the name or the IP address of a different Universal CMDB server (other than the UCMDB server for the existing Probe) with which the second Probe is to connect.

     Note  

     • Two Probes installed on the same Windows machine should report to two different UCMDB servers respectively. For the second Probe you install, make sure you specify a different Universal CMDB server.
     • In a High Availability environment, use the Writer virtual IP address of the load balancer.

   • In the Data Flow Probe address box, enter the IP address or DNS name of the machine on which you are currently installing the Probe, or accept the default.

     Note If the Data Flow Probe machine has more than one IP address, enter a specific IP address, and not the DNS name.

   Click Next.

   Note If you do not enter the address of the application server, or if there is no TCP connection to the application server via default ports (8080,8443,80) (possibly because the application server has not fully started yet), a message is displayed. You can choose to continue to install the Probe without entering the address, or return to the previous page to add the address.

10. A second UCMDB Data Flow Probe Configuration page opens, enabling you to configure an identifier for the Probe.

    • In the Data Flow Probe Identifier box, enter a name for the second Probe that is used to identify it in your environment.

      Note

      • The Probe identifier is case sensitive, must be unique for each Probe in your deployment, and it must not exceed 50 characters.

      • Make sure you enter a unique identifier for the second Probe.

    • To use the default UCMDB IP address or machine name, as defined in the UCMDB Server installation, select Use Default CMDB Domain.

      The Default UCMDB Domain is also configurable in UCMDB's Infrastructure Settings module. For details, see the Universal CMDB Administration Guide.

    Click Next.

11. The UCMDB Data Flow Probe Memory Size page opens.

    Note For the second Probe you install, the Probe Domain Config and Probe Working Mode pages are skipped.

    Define the minimum and maximum memory, in megabytes, to be allocated to the second Probe.

    Note For information about changing the maximum heap size value at a later point in time, see the Universal CMDB Data Flow Management Guide.

    Click Next.

12. The PostgreSQL Account Configuration page opens.

    The PostgreSQL Data Flow Probe account is used by the Data Flow Probe to connect to the PostgreSQL database. This account is less privileged compared to the PostgreSQL root account. Its password is encrypted in the DataFlowProbe.properties configuration file.

    Enter the password for the PostgreSQL Data Flow Probe account and enter it a second time for confirmation.

    Note Changing this password requires an update to the DataFlowProbe.properties file.

    Click Next.

13. A second PostgreSQL Account Configuration page opens where you configure the PostgreSQL root account. The PostgreSQL root account is the account used to administer the PostgreSQL database. When set, it may need to be provided while executing scripts under the Probe's installation.

    Enter the password for the PostgreSQL Data Flow Probe account, and enter it a second time for confirmation.

    Note Changing the root account password does not affect operation of the Probe.

    Click Next.

14. The Configuration for System Administrator Password page opens.

    Enter the password for the sysadmin account. Make sure the password meets the default password.

15. The Account Configuration for Uploading Scan Files page opens. This is used for Manual Scanner Deployment mode. It enables uploading scan files directly to the XML Enricher's incoming directory on the Data Flow Probe using HTTP or HTTPS.

    Enter the user name and password for this account, and enter the password a second time for confirmation. The default user name is UploadScanFile.

    Click Next.

16. The Pre-Installation Summary page opens.

    Review the selections you have made and click Install to complete the installation of the second Probe.

17. When the installation is complete, the Install Complete page opens.

    Note  

    • Any errors occurring during installation are written to the following file:

      C:\hp\UCMDB\<DataFlowProbe_2_InstallDir>\UninstallerData\Logs\UCMDB_Data_Flow_Probe_Install_<install date and time>.log

    • Any database-related errors occurring during installation are written to the following log:

      C:\hp\UCMDB\<DataFlowProbe_2_InstallDir>\runtime\log\postgresql.log

    Click Done.

18. If you customized the key.bin file, copy the key.bin file that you saved earlier to C:\hp\UCMDB\DataFlowProbe\conf\security.

19. Start the second Probe: Select Start > All Programs > UCMDB (2) > Start Data Flow Probe.

    To start the Probe from the console, at the command prompt execute the following script: C:\hp\UCMDB\<DataFlowProbe_2_InstallDir>\bin\gateway.bat console.

    Note  

    • In order for the Probe to connect to the application server, the application server must be fully started.

    • The Probe is displayed in UCMDB in the Data Flow Management module, under Data Flow Probe Setup > <Domain> > Probes.
