Upgrade projects

To work in the current version of ALM with projects created in previous ALM versions, you must upgrade your projects to align them with the required configurations of the current version of ALM.

Before upgrading, verify and repair your projects to detect and correct errors in your database user schema and data.

Overview

Understand the following before you verify, repair, and upgrade projects.

Back up projects

When you run the repair or upgrade process, ALM performs changes on your projects to align them with the specifications for the current version of ALM. You must back up your projects before you start to repair or upgrade them.

The repair process makes changes to the project database schema only. Before running the repair process, you should back up the project database schema on the database server, but you do not need to back up the project data in the file system.

Before you run the upgrade process, perform a full backup of your projects that includes the project database schema and the project data.
Define an exception file

If you have made changes to the schema such as the addition of tables or columns, the upgrade process may fail. You can define an exception file for objects that are added manually to the database user schema, and are not defined in the schema configuration file. This instructs ALM to ignore these changes during the upgrade process.

You must use the same exception file when running the verification, repair, or upgrade process.

You can set an exception file for a single project or for all projects in Site Administration.
Verification process

You run the verification process to check the correctness of your database user schema and data. Although your database user schema and data may be correct for your previous ALM version, they may not be consistent with the specifications for the current version of ALM.

The verification process detects problems in your environment, settings, schema structure, and data integrity that could cause the upgrade to fail. It generates a verification log which informs you of problems that can be repaired by ALM and problems that you should manually repair.
Repair process

The repair process fixes most data and schema issues found by the verification process.

If the verification process detects problems that can cause data loss, the repair process does not fix these automatically. You need to repair these problems manually. To find out whether a particular issue is handled automatically or manually, refer to the verification log.
Repair/upgrade mode By default, the repair and upgrade processes run in non-silent mode. When running the processes in non-silent mode, ALM may pause and prompt you for information when an error occurs. Instead, you can select to run the processes in silent mode. When running the processes in silent mode, ALM aborts the processes without prompting you for input.
Use verified, repaired, or upgraded projects in a previous version

After a project is verified or repaired, you can still use it with a previous ALM version.

After a project is upgraded, you can no longer use the project with a previous ALM version.

Back up projects

A full backup of a project includes the backup of the project database schema and the backup of the project data.

The repair process makes changes to the project database schema only. Before running the repair process, you should back up the project database schema on the database server. You do not need to back up the project data in the file system.

Before you run the upgrade process, perform a full backup of your projects that includes the project database schema and the project data.

To back up the project database schema on the database server:

Microsoft SQL database For information on backing up a schema on a Microsoft SQL database, see How to back up and restore MS SQL database.
Oracle database For information on backing up a schema on an Oracle database, see How to export and import an Oracle database to dump files.

To back up the project data in the file system:

In the file system, ensure that all data, including automated tests scripts and results, and attachments, is saved in the project directory under the repository defined during the installation of ALM. Make a copy of this project directory including all subdirectories and files.

Define an exception file

You can use the exception file to ignore warnings for extra tables, views, columns, and sequences. You can set an exception file for a single project or for all projects.

To define an exception file:

  1. Copy the SchemaExceptions.xml file from the ALM installation directory. By default, the file is located in <ALM installation path>\data\sa\DomsInfo\MaintenanceData.

  2. Create the exception file, for example, my_exceptions.xml, and define the exceptions as follows:

    • For an extra table:

      Copy code 
      <TableMissing>
               <object pattern="MY_Table" type="extra"/> 
      </TableMissing>

    • For an extra view:

      Copy code 
      <ViewMissing>
               <object pattern="MY_VIEW" type="extra"/> 
      </ViewMissing>

    • For an extra column:

      Copy code 
      <ColumnMissing>
               <object pattern="MY_COLUMN" type="extra"/> 
      </ColumnMissing>

    • For an extra sequence:

      Copy code 
      <SequenceMissing>
               <object pattern="MY_SEQUENCE" type="extra"/> 
      </SequenceMissing>

  3. To set an exception file for a single project:

    1. Open Site Administration > Projects tab.

    2. From the projects list, select a project.

    3. In the Details tab, Project Database section, Exception File field, enter the location of your exception file.

  4. To set an exception file for all projects, add the UPGRADE_EXCEPTION_FILE parameter and define the exception file location.

    For details about configuring site parameters, see Set configuration parameters.

Restore projects

If the repair or upgrade process fails, you must restore the backed up projects before trying the process again. A project you restore can be used only in the ALM version from which it was backed up.

To restore a project from a Microsoft SQL database server:

  1. From the SQL Server Enterprise Manager, navigate to the database and select Tools > Restore Database.

  2. Navigate to the backup file, and follow the restore procedure to complete the data restore process.

  3. In Site Administration, restore access to the project. If you are restoring your project from a different directory, or if you renamed your schema, you must update the dbid.xml file accordingly. For details, see Restore access to a project.

  4. If the backup was performed while the project was active, realign the project repository. For details, see Realign a repository.

To restore a project from an Oracle database server:

  1. Copy the backup file to the Oracle server machine.

  2. Using the SQL*Plus utility, log in to the Oracle server using the system account.

  3. Create a user for the ALM project. Make sure you create it with the same name as the project name (or the Oracle user name) when the project was exported.

    Use these SQL statements:

    Copy code 
    CREATE USER [<project name>] IDENTIFIED BY tdtdtd DEFAULT TABLESPACE TD_data TEMPORARY TABLESPACE TD_TEMP;

    GRANT CONNECT,RESOURCE TO [<project name>];

  4. On the ALM installation DVD, Locate the \Utilities\Databases\Scripts directory. Open the qc_project_db___oracle.sql file and follow the instructions.

  5. Using the command line, type imp to run the import utility.

  6. Follow the prompt, and log in to the Oracle server using the system account. Make sure you import all the dump files.

    After all tables have been successfully imported, a confirmation message displays.

  7. In Site Administration, restore access to the project. If you are restoring your project from a different directory, or if you renamed your schema, you must update the dbid.xml file accordingly. For details, see Restore access to a project.

  8. If the backup was performed while the project was active, realign the project repository. For details, see Realign a repository.

To restore a repository from the file system:

  1. Copy the backed up repository to the ALM repository.

  2. In Site Administration, restore access to the project. If you are restoring your project from a different directory, or if you renamed your schema, you must update the dbid.xml file accordingly. For details, see Restore access to a project.

  3. If the backup was performed while the project was active, realign the project repository. For details, see Realign a repository.
