    Migrate EventLog Analyzer Data from MySQL to MS SQL Database

    EventLog Analyzer allows you to migrate the existing EventLog Analyzer data available in MySQL database to MS SQL database.

    This procedure is applicable only if you are already using EventLog Analyzer with MySQL and you want to change the database to MS SQL.

    Note:

    Re-registering the Managed Server after the database has been changed:

    • When the Managed Server is installed, it is registered with Admin Server as Managed Server with MySQL.
    • If the database of the Managed Server is changed from MySQL to MS SQL, the database of the Admin server also needs to be changed from MySQL to MS SQL.
    • Then, the managed server has to be re-registered with Admin Server with the help of <EventLog Analyzer Home>/troubleshooting/registerWithAdminServer.bat file (or registerWithAdminServer.sh file)

    After changing the database, when the Managed Server is started as a service, there will not be any prompt to re-register. The user has to ensure that the Managed Server is re-registered with the Admin Server.

    If the user is migrating a distributed setup, the user needs to migrate the entire distributed setup to MSSQL. All Managed servers along with the admin server should be migrated to MSSQL.

    If you want to configure MS SQL for a fresh installation of EventLog Analyzer server, please refer the Configuring MS SQL Database page and follow the procedure given there.

    The steps to migrate and run the EventLog Analyzer server with SQL SERVER as the database is given below:

    1. Stop the EventLog Analyzer Server/Service.
    2. Invoke the <EventLog Analyzer Home>/tools/backUpDatabase.bat in command prompt to backup the data available in the MySQL database and wait till the data backup is completed. By default, the backup file will be stored under <EventLog Analyzer Home>/backup directory with the file name like 'backup_eventlog_<Build_Number>_database_MM_DD_YY_hh_mm.data'.
    3. From the installed MS SQL SERVER, copy the files bcp.exe and bcp.rll to <EventLog Analyzer Home>/bin folder.
      4. Note: If you are copying the above file from SQL server (Version 2012 and above) and EventLog Analyzer is installed in another machine, please install the SQL native client as per the SQL version and CPU type of the EventLog Analyzer machine.

      For MSSQL version 2012, install the native client and for the remaining versions of MSSQL, install the ODBC driver (links given below).

    4. Invoke the <EventLog Analyzer Home>/tools/changeDBServer.bat in command prompt to configure the MS SQL SERVER credentials like ServerName, Port, User Name and Password.
    5. Database Setup Wizard pops-up.
    6. In the wizard screen, select Server Type as SQL Server. Available SQL Server Instances are listed in a combo box. Enter the Device Name and Port of the SQL Server from the instances.
    7. Select the authentication type using the "Connect Using:" option.
    8. The options are:
      9. Note: Ensure that both EventLog Analyzer Server and MS SQL Server are in the same domain and logged in with the same Domain Administrator credentials.

      Windows Authentication

      For EventLog Analyzer version 8.0 (Build 8010) onwards,

      Windows Authentication

      SQL Server Authentication

      For SQL Server Authentication, enter the User Name and Password.

      SQL authentication
    9. Click the Test button to check whether the credentials are correct. If the test fails, the credentials might be wrong. Recheck and enter the correct credentials.
    10. Click the Save button to save the SQL Server configuration. Note that it will take a few minutes to configure the settings of the SQL Server database.
    11. Invoke the <EventLog Analyzer Home>/bin/run.bat to start the EventLog Analyzer server in the command prompt.
    12. After the server is started completely, stop the server by terminating the run.bat in the command prompt or invoke the <EventLog Analyzer Home>/bin/shutdown.bat.
    13. Invoke the <EventLog Analyzer Home>tools/restoreDatabase.bat, browse and select the created backup file. Now click on 'OK' and wait till the database is completely restored.
      14. Restore data
      Note: Executing the restoreDatabase.bat will delete the existing data, if any.
    14. Start the EventLog Analyzer Server/Service to work with the MS SQL Server as the database.
