Processing DBQueue tasks

The tasks queued in the DBQueue are the result of triggering, modifications to configuration parameters (for example, changes to a configuration parameter concerning inheritance) or running scheduled tasks. The DBQueue Processor processes tasks in the DBQueue. The DBQueue Processor uses several slots for running tasks in parallel. Internal tasks are processed by the Database Agent Service. Ensure that the Database Agent Service is installed and configured.

Detailed information about this topic

DBQueue Processor configuration for test, development, or productive environments

You use the staging level of the One Identity Manager database to specify whether the database is a test database, development database, or a live database. A number of database settings are controlled by the staging level.

If you change the database's staging level, the following settings are configured.

Maximum number of slots according to the hardware configuration

The DBQueue Processor default configuration settings are configured for normal operation and do not normally need to be modified.

If several databases are operating in a managed instance in Azure SQL Database, you can fix the number of slots. In the Designer, adjust the following configuration parameters.

  • QBM | DBServerAgent | CountSlotAgents: Exact number of slots. If the configuration parameter is set, the given number of slots are always set up. There is no internal calculation of the number of slots based on the hardware configuration. Changing the server's configuration has no effect. The value 15 is recommended.

    NOTE: This configuration parameter is not recommended for implementing a database on an SQL Server. For implementing a database on an SQL Server, it is standard practice to use the hardware configuration to determine the slots.

The configuration settings are reduced for test environments and development environments because several databases may be located on a server. If it is necessary to change the settings for test environments or development environments for reasons of performance, you must modify the following configuration parameter settings in the Designer.

  • QBM | DBQueue | CountSlotsMax: Maximum number of slots to be used.

    Use this configuration parameter to reduce the number of slots if required. Values lower than 5 are not permitted.

    Exception: Enter a value of 0 for using the maximum number of slots available based on the hardware configuration.

  • QBM | DBQueue | KeepAlive: Maximum runtime of the central dispatcher. Tasks on slots currently in use are still processed when the timeout expires. Then the slot are stopped and the central dispatcher exits.

    The lowest permitted value for runtime is 5 minutes; the maximum permitted value is 720 minutes.

Configuring notification behavior for DBQueue Processor initialization

If errors occur during initialization of the DBQueue Processor, messages are written to the application log. You can use the results display in the Microsoft Management Console, for example, to view the application log.

Use the QBM | DBServerAgent | CreateNotification configuration parameter to configure in which cases error messages are written to the application log. In the Designer, you can modify the configuration parameter as required.

Permitted values are:

  • 0: No logging.

  • 1: Only success messages are logged.

  • 2: Only error messages are logged.

  • 3: All messages are logged.

Reinitializing the DBQueue Processor

IMPORTANT: Select a user that you use for migrating the database to run the SQL queries.

  • You must run the QBM_PDBQueuePrepare procedure once manually when the server hardware has been extended and when custom DBQueue Processor tasks have been created.

  • You must run the QBM_PDBQueuePrepare and QBM_PWatchDogPrepare procedures once when you set up a reference database for test and development.

    Use a suitable program for running SQL queries to run the following procedures in the reference database just once.

    exec QBM_PWatchDogPrepare

    exec QBM_PDBQueuePrepare 0,1
