MDM Workflow Tasks

The following workflow tasks are available in MDM:

Run MDM Export
Run MDM Load
Run MDM Multi Load

For more information about how to use workflow tasks, see Workflow Basics and Workflow Tutorials.

Run MDM export

Starts an MDM export operation. See Input and Output Interfaces > Adding an Export Operation section in the documentation.

Properties

Name	Type	Description	Expression support
Operation name	mandatory	Comma-separated list of operation IDs to be invoked. Workflow fails at runtime if any of the operations is unknown. Trailing space is allowed (operation names are trimmed), empty operation names are discarded. If the expression evaluates to an empty list, the task succeeds as well.	semi-expression
Parameters	optional	See Common parameters properties.	dynamic

Name

Type

Description

Expression support

Operation name

mandatory

Comma-separated list of operation IDs to be invoked. Workflow fails at runtime if any of the operations is unknown.

Trailing space is allowed (operation names are trimmed), empty operation names are discarded.

If the expression evaluates to an empty list, the task succeeds as well.

semi-expression

Parameters

optional

See Common parameters properties.

dynamic

<EwfTaskElement>
    <acceptMode>ALL_VALID</acceptMode>
    <executable operationName="full_instance_crm_export" class="com.ataccama.nme.ext.workflow.RunNmeBatchExport">
        <parameters/>
    </executable>
    <id>031_BatchExport</id>
    <name>Perform full instance batch export (CRM system data only)</name>
    <priority>0</priority>
</EwfTaskElement>

Common parameters properties

parameters - A list of name (constant)-value (semi-expression) pairs that are passed to batch operations. These can be used as component parameters, path variable definitions, or elements in more complex parameter definitions.

Name Type Description Expression support

Name	Type	Description	Expression support
Name	mandatory	Name of the parameter as defined in the plan (for example, `path_to_file`, `DATA`).	none
Value	mandatory	Value of the parameter (for example, real path: `/mnt/data`).	semi-expression

Name

mandatory

Name of the parameter as defined in the plan (for example, path_to_file, DATA).

none

Value

mandatory

Value of the parameter (for example, real path: /mnt/data).

semi-expression

<parameters>
    <p name="etc_pv" value="${etcFolder}" />
    <p name="parameter" value="${paramValue}" />
    <p name="referenceTransactionId" value="${ref_tid}" />
    <p name="string_constant" value="\'INCR\'" />
    <p name="integer_constant" value="1" />
</parameters>

The referenceTransactionId parameter can be used only for export. It enables starting the export from a particular transaction ID.

Predefined variables

None.

Logging

The step redirects logging of the MDM plan to the log file located in the workflow resources directory (as specified in the server configuration).

For each workflow instance, there is a directory in Files > storage > resources > workflow named wfinst_<instance_id>/task_<#>.log. This directory and logging file are created only if there is some content in the log file.

Run MDM load

Starts a batch load for a connected system. See Input and Output Interfaces > Adding a Batch Load Operation section in the documentation.

Properties

Name	Type	Description	Expression support
Operation name	mandatory	ID of the operation to be invoked. Workflow fails to load if the operation is not known.	semi-expression
Parameters	optional	See the following sections.	dynamic

Name

Type

Description

Expression support

Operation name

mandatory

ID of the operation to be invoked. Workflow fails to load if the operation is not known.

semi-expression

Parameters

optional

See the following sections.

dynamic

Predefined variables

None

Example

Sample

<executable class="com.ataccama.nme.ext.workflow.RunNmeBatchLoad">
    <operationName>full_load_s2_par</operationName>
    <parameters>
        <p name="etc_pv" value="${etcFolder}" />
    </parameters>
</executable>

Logging

The step redirects logging of the MDM plan to the log file located in the workflow resources directory (as specified in the server configuration). For each workflow instance, there is a directory in Files > storage > resources > workflow named wfinst_<instance_id>/task_<#>.log. This directory and logging file are created only if there is some content in the log file.

Run MDM multi load

Starts a batch load for one or more connected systems. Grouping of multiple batch operations can increase processing throughput.

Properties

Name	Type	Description	Expression support
Operation names	mandatory	ID of the operation to be invoked. Workflow fails to load if the operation is not known.	semi-expression
Parameters	optional	See the following sections.	dynamic

Name

Type

Description

Expression support

Operation names

mandatory

ID of the operation to be invoked. Workflow fails to load if the operation is not known.

semi-expression

Parameters

optional

See the following sections.

dynamic

Predefined variables

None.

Example

Sample

<executable class="com.ataccama.nme.ext.workflow.RunNmeMultiLoad">
    <operationNames>delta_load,full_load_s2</operationNames>
    <parameters/>
</executable>

Logging

The step redirects logging of the MDM plan to the log file located in the workflow resources directory (as specified in the server config). For each workflow instance, there is a directory in Files > storage > resources > workflow named wfinst_<instance_id>/task_<#>.log. This directory and logging file are created only if there is some content in the log file.

Maintenance tasks

Lookup Refresh

This task reloads the "virtual filesystem" for lookups (lookup refresh), including service restart. This task has no parameters or output variables.

<executable class="com.ataccama.adt.dqc.tasks.EwfReloadVfsTask">
</executable>

It functions exactly the same way as with the online server. See Versioned File System Component.
