Upgrading IT Data Analytics in a multiple server environment silently

Where you are in the Upgrade process

You can upgrade IT Data Analytics in a multiple server environment, silently, by doing a custom upgrade. The silent upgrade obtains the required user inputs from the options files. You can download sample options files from within the procedure below, or you can generate them.

To perform a custom upgrade silently

Do the following:

1. Log in to the host computer on which you want to upgrade IT Data Analytics, and delete all the files from the temporary directory: 
   • (Windows) %temp%
   • (Linux) /tmp
2. Extract the downloaded files (the installer) to a temporary location outside the following location to avoid any file sharing conflicts.
   • (Windows) C:\Program Files
   • (Linux) /opt
   It is strongly recommended that you exit all programs before starting the installation.
3. From the command prompt, navigate to the Disk1 folder:
   • (Windows) <DownloadLocation>\BMC-TrueSight-IT-Data-Analytics\Disk1\
   • (Linux) <DownloadLocation>/BMC-TrueSight-IT-Data-Analytics/Disk1/

4. Download the following sample options files depending on the component that you want to upgrade and your environment, or generate one. To generate the file, go to Step 6.

5. Copy the sample options file to the following folder on every computer where you want to upgrade the components:

   • (Windows) C:\Program Files\BMC Software\TrueSight\ITDA
   • (Linux) /opt/bmc/TrueSight/ITDA

   To install the product in a different location, change the value of the installLocation property in the options file.

6. Run the following command to generate the options file:
   1. From the command prompt, run the following command to generate the options file:

      • (Windows) setup.exe –DGENERATE_OPTIONS_FILE=pathToOptionsFile
      • (Linux) As a non-root user, run setup.bin –DGENERATE_OPTIONS_FILE=pathToOptionsFile

        NotepathToOptionsFile must contain the name of the options file. If the file name or path includes a space, enclose the path and name in double quotes.

      Examples:

      • (Windows - path with space) setup.exe –DGENERATE_OPTIONS_FILE="C:\temp folder\Disk1\options File.txt"
      • (Linux - path with space) setup.bin –DGENERATE_OPTIONS_FILE="opt/temp folder/Disk1/options File.txt"
   2. This command launches the TrueSight IT Data Analytics installation wizard. You must complete the wizard-based installation once, to populate the options file with properties. Your options file is then ready to be used in silent installation.
7. You will need to type the Remedy Single Sign-On password in an encrypted form in the options file in Step 8. Encrypt this password using the EncryptPWD utility:
   
   
   1. Open the EncryptPWD utility by navigating to:
      • (Windows) <DownloadLocation>\BMC-TrueSight-IT-Data-Analytics\Disk1\utility\EncryptPWD
      • (Linux) <DownloadLocation>/BMC-TrueSight-IT-Data-Analytics/Disk1/utility/EncryptPWD 
   2. Run the tool, and click the Encrypt tab.
   3. Type the password, confirm it, and click Encrypt.
   4. Note down the encrypted password (from the Encrypted Password field)
   
   
8. Open and edit the options file. You can either retain the default values for the properties or change them, and save the file. The options file defines the installation properties in the form of a prefix tag followed by a property name and value pair.
   Property details

   Prefix tags for silent installation properties:

   • -P: Precedes directory properties
   • -A: Precedes application features
   • -J: Precedes Java properties
9. Run the following command to start the silent installation. Type the complete path to the options file in the command. If the path includes a blank space, enclose the path within double quotes.
   • (Windows) setup.exe -silent -DOPTIONS_FILE="<path_to_itda_silent_options_file>"
   • (Linux) ./setup.bin -silent -DOPTIONS_FILE="<path_to_itda_silent_options_file>"
     
   The installation may take up to 10 minutes. After the installation is complete, the Installation Summary page is displayed.
10. You can periodically check the installation status by checking the itda_install_log.txt file located at:
    • (Windows)%temp%
    • (Linux)  /tmpSearch for the following log message in the itda_install_log.txt file to ensure that TrueSight IT Data Analytics is installed successfully:BMC TrueSight IT Data Analytics 11.3.01 install succeeded
11. The following environment variable points to the IT Data Analytics installation path after the upgrade.
    • (Windows) %BMC_ITDA_HOME%
    • (Linux) $BMC_ITDA_HOME
12. Run the following command to verify the TrueSight IT Data Analytics status:
    • (Windows) Navigate to the TrueSight\ITDA\bin directory, and run run.bat -status command.
    • (Linux) Navigate to the TrueSight/ITDA/bin directory, and run ./run.sh -status command.
    A list of IT Data Analytics services are displayed as shown in the following example:
    TrueSight IT Data Analytics Indexer:
    The requested service has already been started.
    TrueSight IT Data Analytics ConfigDB:
    The requested service has already been started.
    TrueSight IT Data Analytics Server:
    The requested service has already been started.
    TrueSight IT Data Analytics Collection Station:
    The requested service has already been started.
13. (Optional) Start using Remedy Single Sign-On as your authentication mechanism by running the enablesso CLI command. Using Remedy Single Sign-On is required if you plan to use TrueSight IT Data Analytics in conjunction with the TrueSight products For more information, see User-authentication-options.
14. (Optional) If you are upgrading from TrueSight IT Data Analyticsversion 2.7, ensure that you modify the properties for re-indexing after upgrading.
    To modify the properties for re-indexing

    When you upgrade from TrueSight IT Data Analyticsversion 2.7, the indexes are migrated to TrueSight IT Data Analytics11.3.01 by default. You can modify some properties to manage the way you are re-indexing the data. Search features of TrueSight IT Data Analytics such as histogram, facets, and search counts of older data are available after the migration is complete. The migration may take some time depending on the size of data.

    Notes

    • After upgrading, if you create an Upload file type of data collector to collect earlier data, then it is possible that the collected data is added to an existing index. As a result, the search performed on this data will work in a case-sensitive way.
    • If you have existing external configurations for the TrueSight Infrastructure Management (or ProactiveNet) cells, you might need to edit them and change the encryption key. Changing the encryption key is required if TLS is enabled for TrueSight Infrastructure Management on TrueSight Operations Management 10.7. You must import the certificates generated on the TrueSight Operations Management side to be able to create new external configurations in version  11.3.01 of TrueSight IT Data Analytics. For more information, see Enabling security for communication with Infrastructure Management server
    • Re-indexing may increase CPU utilization. You can use throttling, which increases the time taken for re-indexing, but reduces the CPU utilization. For more information refer to the table.

    Do the following:

    1. Log in to the host computer on which you have installed TrueSight IT Data Analytics.
    2. Navigate to the following location: <ITDA_INSTALLATION_DIRECTORY>\BMC Software\TrueSight\ITDA\custom\conf\server\olaengineCustomConfig.properties
    3. Modify the values of the following properties in the olaengineCustomConfig.properties file:

       Property	Additional information
       reindex.enabled	Enables re-indexing.Example reindex.enabled=true By default the value is set to true.Note: If reindexed.enabled is set to false, the previously indexed data may not be compatible with the new version of TrueSight IT Data Analytics .Features such histograms and facets of older data will not be available.
       #reindex.number.of.last.days	Sets the number of days for which the re-indexing is to be done.Example #reindex.number.of.last.days=14 You can set the value to the number of days for which you want the re-indexing to be done. Depending on the number of days that you specify, the previously indexed data will be available for re-indexing. TipYou must uncomment the property if you want to change it.
       reindex.wait.before.next.bulk.write.millis	Sets the wait time in milliseconds before writing the next bulk (or chunk) into new Indexes while re-indexing.Example reindex.wait.before.next.bulk.write.millis=0 The default value is 0. The default value 0 means that there should be no wait time.Setting this value enables you to decrease the Indexer CPU usage while re-indexing. Increasing this value will decrease the CPU usage on the indexer.
       reindex.bulk.flush.threshold.millis	Sets the time in milliseconds; that are passed after the last bulk flush or start of the bulk process. The bulk that is accumulated will be flushed (written) into the Indexer after this period is over. This happens irrespective of the bulk size.Example reindex.bulk.flush.threshold.millis=60000 The default value is 60000.

       NoteAfter changing the properties, if the Console Server component is already running, restart it.
15. Restore the backed up keystore file (bmcitda.jks), and restart the IT Data Analytics server after upgrading.Note: The bmcitda.jks keystore file is backed up before upgrading to ensure that the custom certificates are not lost after upgrading.
