There are four types of workflow configurations:

• Batch

• Real-Time

• Task

• System Task

Batch Workflow

A batch workflow processes input from a specific source, usually a file. The workflow creates batches from the data and processes them one by one.  

In a batch workflow data is collected by a single collecting agent in a transaction-safe manner. A single batch is collected (only once) and is fully processed by the workflow before the next batch is collected.  

A batch workflow:  

• Processes batches, one at a time.

• Is started either manually or by a scheduled trigger.  

• Stops either when it finishes processing the input, or when aborted.

Real-Time Workflow

Real-time workflows are used in systems where instant processing requests need to be addressed as they occur.

In real-time workflows most of the collecting agents communicate in a two-way manner; they receive requests and provide replies.

A real-time workflow:

•   Can have more than one collecting agent

• Once started, the real-time workflows remain active. A real-time workflow is started either manually or by a scheduled trigger and stops either manually or due to an error.

• Processes reside in memory. Transaction safety must be handled prior to collection and after distribution.

• Errors are registered in the System Log and the workflow continues to run. Real-time workflow error handling rarely leads to workflow aborts.

Task Workflows

Task workflows are single-agent workflows that execute user-defined SQL, shell scripts, or unit tests.

System Task Workflows

comes with built-in System Task workflows. System Task workflows and groups let you perform activities such as log and run-time data cleanup.

System Task workflows include the following types:

• Archive Cleaner

• Configuration Cleaner

• Data Veracity Maintenance

• ECS Maintenance

• Statistics Cleaner

• System Backup

• System Log Cleaner

• User Cleanup

This section includes information about:

• Opening a System Task Workflow

• Modifying a System Task Workflow Configuration

Opening a System Task Workflow

You open a System Task Workflow from the workflow configurations list (Build menu).

To open a System Task, double-click a System Task workflow or workflow group in the Configurations pane.

Open

System Task Workflows list

Modifying a System Task Workflow Configuration

You modify all the System Task Workflow configurations at the template level. The workflow properties are all set to Final and cannot be modified.

•   You can modify a System Task configuration, including its scheduling criteria, but you cannot create or remove a System Task configuration.

•   The Archive Cleaner Workflow lets you modify only its scheduling criteria. For further information see Scheduling in Managing a Workflow Group.  

  To Modify a System Task Workflow:  

1. Open the System Task Workflow that you want to modify by double-clicking on it or right-clicking and selecting View Configuration.

2. Double-click the agent icon. The agent's configuration dialog opens.

3. Perform the changes and click OK.

4. Save the workflow.

Archive Cleaner

The Archive Cleaner System Task lets you remove old archived files from the file system. Archive Cleaner operates according to data that it receives from the Archive profiles.

Configuration Cleaner

The Configuration Cleaner lets you specify the maximum age of an old configuration before it is removed. 

To configure the Configuration Cleaner:

1.  Select a configuration type from the table and click the entry in the Keep column. A drop-down list appears.

2.  Select one of the following options: Always, Days, or Versions.

Data Veracity Maintenance

The Data Veracity Maintenance system task removes outdated Data Veracity data, provided that the state is REPROCESSED or DELETE_APPROVED. For more information see Data Veracity Maintenance System Task. 

Open

The Data Veracity Maintenance Task

ECS Maintenance

ECS Maintenance lets you remove old ECS data from the file system, provided that the state is REPROCESSED. For more information see ECS Maintenance System Task.

Statistics Cleaner

 The Statistics Cleaner lets you remove old statistics data that has been collected by the Statistics server and stored in the database.

System Backup

System Backup enables you to create a backup of all the configurations in the system. A backup file is saved on the host machine where the Platform application is installed. 

The System Backup files are stored in $MZ_HOME/backup/yyyy_MM, where yyyy_MM is translated to the current year and month, and $MZ_HOME/backup is the default path. The system saves a backup file and names it according to the following format: backup_<date>.zip. In addition, System Backup lets you specify the maximum age of backup files before they are removed. You can change this location using the following command:

The System Backup configuration dialog contains two tabs:

• System Backup: To enable the option. 

• Cleanup: To configure the option.

System Log Cleaner

The System Log Cleaner deletes the System Log periodically. You specify how long to keep different message types in the System Log Cleaner configuration.

User Cleanup Task

The User Cleanup Task automatically deletes inactive users. If SSO is turned on, a user logged in through SSO is added in the system upon login. However, the user is not removed when it is deleted from the OIDC server. The User Cleanup Task deletes users that have not logged in for a configurable number of days.
