Managing WFM Database Utility

Managing the Workforce Management (WFM) Database Utility entails configuring, updating, maintaining, backing up and restoring, and if required, migrating. WFM Database Utility provides a number of database-related functions in a single interface that enable you to perform these tasks, which are described in these sections:

Overview

Use the Workforce Management Database Utility to:

  • Create and configure a new database.
  • Update your database to release 8.1.
  • Perform other database updates as needed.
  • Perform regular maintenance, such as cleanup of obsolete data.
  • Migrate data from a previous WFM versions to a WFM 8.1 database.
Important
In order for the Configuration Utility to work properly, you must set Microsoft SQL and Oracle database management systems to be case-insensitive.


The WFM Database Utility and the WFM Configuration Utility use the same Application object, which is typically named WFM Client Application.

New Database Configuration

If your first installed release of this product is Workforce Management 7.6 (or higher) or if you are migrating from release 6.x, you will use a new database. The WFM Database Utility populates and configures the new database for you, setting up the necessary tables, views, indexes, and so on. For instructions, see Installing WFM Database Utility. If you are already using WFM 7.x, its not necessary to install a new database. Simply perform a database update to transition your database to release 8.1.

DB2 Configuration Recommendations

The settings in this section are required when you create the WFM database, and will optimize its performance. Click the + sign to display the details for each recommended setting. See also Configuring the DB2 Database.

Buffer Pool

The default buffer pool Page size (4) and other values are too small. Genesys recommends you enter the following values for the settings in the Alter Buffer Pool dialog box:

Table 1: Recommended Buffer Pool Settings for DB2

Setting Default value Recommended value
Page Size 4 32
Bufferpool size 1000 60000
Size in 4KB pages 1000 60000
Regular Table
Space
Create a Regular table space using buffer pool with 32KB Page size.
System Temporary
table space
Create a System Temporary table space using buffer pool with 32KB Page size.
User Temporary
Table Space
Create a User Temporary table space using buffer pool with 32KB Page size.

Using the Table Spaces

In the Change User dialog box, on the Table Space tab, ensure the table spaces you want to use, are checked (see figure below).

Important
Ensure you create the same user as your operating system user.

Tuning the Transaction Log Characteristics

Before you enable a database for spatial operations, ensure that you have enough transaction log capacity. The default values for the transaction log configuration parameters do not provide sufficient transaction log capacity if your plans include:

  • Enabling a database for spatial operations in a Windows environment
  • Using the ST_import_shape stored procedure to import from shape files
  • Using geocoding with a large commit scope
  • Running concurrent transactions

If you plan to use any of these now or in the future, you need to increase the capacity of your transaction log for the database, by increasing one or more of the transaction log configuration parameters. Otherwise, you can use the default characteristics and proceed to tuning the application heap size.

Recommended Minimum Values

See the table below for the recommended minimum values for the three transaction log configuration parameters.

Table 2: Recommended minimum values for transaction configuration parameters

Parameter Description Default value Recommended minimum value
LOGFILSIZ Specifies the log file size as a number of 4-KB blocks 1000 1000
LOGPRIMARY Specifies how many primary log files are to be pre-allocated to the recovery log files 3 10
LOGSECOND Specifies the number of secondary log files 2 2

If the capacity of your transaction log is not adequate, the following error message is issued when you try to enable a database for spatial operations: GSE0010N Not enough log space is available to DB2.

Update Your WFM Database

From time to time, Genesys issues Maintenance Releases (MR) of its products. Some of the Workforce Management updates require database updates. If so, you can perform them using the WFM Database Utility.

Important
If you are migrating from WFM 7.x to 8.1, all you need to do to your database is to update it. You do not need to create a new database.

Do You Need to Update Your Database?

You might need to update your database, but perhaps you are not sure. Use the steps to help you decide:

  1. Open the WFM Database Utility.
  2. Check lower-right in the main window to see whether it indicates that your database is up-to-date. The database version number should correspond to the version number of the WFM Database Utility you are running.

To update the database, see Performing a Database Update.

Database Maintenance

To properly maintain your database, you might need to clean it up periodically to remove obsolete data. To do so, see Performing a Database Cleanup.

Back to Top

Back Up and Restore Your Database

You can use the WFM Database Utility to back up the data in your Workforce Management database to a local file and then restore it if necessary. The local files are in Microsoft Access format.

Important
An Access 2002 .MDB file has a maximum database size of about 2 GB.

To backup and/or restore your WFM database, see Performing a Backup and Restoring Your Database.

Starting in 8.1.3, you can use the beta Backup-Restore Utility (BRU), which provides an improved method of backing up and restoring the WFM Database. See Using the Backup-Restore Utility.

Database Migration

At some point, you might have to migrate data from a previous release to a current one. To do this, use the WFM Database Utility to transfer your existing data into the new database. After reading this topic, see the Migrating Data.

  • If you are migrating from release 7.x to 8.1, use the Update Database feature of the Database Utility.

To migrate data into a WFM 8.1 database that is in use, you must update the database to the latest version required by the WFM Database Utility you are using. To do this, use the Update Database feature of the WFM Database Utility.

  • If you are migrating from release 6.x to 8.1, you must migrate your 6.5 data to a new 8.1 database, which the migration utility creates for you.

You can migrate performance data from a WFM 6.5. database to your WFM 8.1 database after you have started using WFM 8.1. This enables you to bring performance data into your database that was collected during the database migration.

For migration instructions, see the "Workforce Management Migration Procedures” chapter in the Genesys Migration Guide.

ETL Database Setup

You can set up an WFM ETL (Extract, Transform and Load) database schema to enable Genesys Infomart or other third-party reporting applications to easily create reports, by incorporating WFM data. Previously, the only way to build customer reports was to use the WFM API.

ETL functionality obtains Schedule, Adherence and Performance information from WFM and stores it into a documented relational database schema. For more information about this functionality or to set up an ETL database schema, see Setting up an ETL Database.

Configuring the DB2 Database

Purpose: To modify the value of one or more configuration parameters in the database.

Prerequisites:

  • You have system administration and installation experience and skill with the associated tools.
  • The DB2 database is installed.

Start of Procedure

  1. From the Configure Database window of the DB2 Control Center, or by reviewing the output from the GET DATABASE CONFIGURATION command, find the current value for the LOGFILSIZ, LOGPRIMARY, and LOGSECOND parameters.
  2. Change one, two, or three of the values, based on the information in Table 2.
  3. Enter a value for each parameter that you want to change.
    You can change the values by issuing one or more of the following commands, where db_name identifies your database:
    • UPDATE DATABASE CONFIGURATION FOR db_name USING LOGFILSIZ 1000
    • UPDATE DATABASE CONFIGURATION FOR db_name USING LOGPRIMARY 10
    • UPDATE DATABASE CONFIGURATION FOR db_name USING LOGSECOND 2
    If the only parameter that you change is LOGSECOND, the change takes effect immediately. In this case, proceed to tuning the application heap size.
  4. If you change the LOGFILSIZ, LOGPRIMARY parameter, or both:
    1. Disconnect all applications from the database.
    2. If the database was explicitly activated, deactivate the database.

    Changes to the LOGFILSIZ or LOGPRIMARY parameters take effect the next time either the database is activated or a connection to the database is established.

    Table 3: Parameter Recommendations Comparison

    Parameter Description Default value Developer's value QA value
    (LOGFILSIZ) Log file size (4KB) 1024 10000 10000
