Upgrading IT Data Analytics in a multiple server environment using the wizard

Where you are in the Upgrade process

The page .Upgrading IT Data Analytics in a single server environment using the wizard v11.3.01 was not found  -- Please check/update the page name used in the MultiExcerpt-Include macro

You can upgrade IT Data Analytics in a multiple server environment using the custom settings and upgrade the components (Configuration Database, Indexer, Collection Station, Console Server, and Search). Custom settings also allow you to authenticate users using Remedy Single Single-On (Remedy SSO). Multiple server upgrade is recommended for performing a medium or a large scale product deployment. 

In a multiple-server deployment, the order in which you upgrade the components and the order in which you start the components is important.

You must upgrade the components in the following order of priority. The following order also applies for starting the services post-upgrade. For more information, see  Starting or stopping product services .

1. Configuration Database

2. Indexer

3. Upgrade the following components (order is not important):
   
   • Collection Station
   • Console Server
   • Search

To perform a typical upgrade using the wizard

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. Run the installer: 

   • (Windows) Run setup.exe from Windows\Disk1

   • (Linux) As a non-root user, run ./setup.bin from Linux/Disk1

4. Review the welcome page, and click Next.
5. Read the license agreement, agree to the terms, and click Next.
6. Select Custom, and click Next.

7. Select the components that you want to upgrade: 

   • Indexer

   • Configuration Database

   • Collection Station

   • Console Server

   • Search

   BMC recommends that you upgrade the Collection Station and Indexer on different computers because they have a higher CPU usage. Although the components can be upgraded in any sequence, the recommended sequence is: 
   a. Configuration Database
   b. Indexer (You must upgrade the Indexer first as the host and port details of the Indexer are required for the Console Server upgrade).
   c. Collection Station, Console Server, Search (can be upgraded in any order).
   
   You must copy the installer to every computer where the components are to be upgraded and run the upgrade process.

8. Depending on your selection, specify values in the following screens and click Next.
   

    Indexer

   • Host name of the computer where you want to install the Indexer. The default is your local host name.
     
   • Port number of the computer where you want to install the Indexer. The default is 9300.

14. Verify that IT Data Analytics has been upgraded successfully.
    To view the upgraded version of the product, reload the current browser page so that the cached content is ignored.
15. (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.

16. (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. Tip You 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.

       Note

       After changing the properties, if the Console Server component is already running, restart it.

17. 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.
