Overview

This property file is used to configure the workflow i.e. how different services will be executed. This file consists of following four types of service configurations:

  • Pickup Service Configuration.
  • Resume Service Configuration.
  • Workflow Configuration.
  • Web Service Configuration.

Configuration

dcma-workflows.properties

Following is the list of configurable properties:

  • PickUpService Configuration

Pick up service runs as a scheduler service which keeps a watch on BATCH_INSTANCE table. Every time a batch is ready to be picked and its status is NEW/READY/LOCKED, this service takes a lock on that batch and triggers the workflow for that batch. Priority of batches to be picked up by pick up service is READY > LOCKED > NEW.

 

Just test table
Configurable property Type
of value		 Value
options		 Description
dcma.pickup.cronjob.expression String Any valid cron expression.
Default Value:
0 0/1 * ? * *
(For this value, pick up service will be invoked every one minute.)		 This parameter specifies the schedule for which Pick up service will run. This is specified as a cron job expression.
server.instance.max.
process.capacity		 Integer Any Integer Value.
Default value: 5		 This parameter specifies the max number of RUNNING batch instances that a server instance can process at a given instance of time.
server.instance.pick.capacity Integer Any Integer Value.
Default value: 3		 This parameter specifies the maximum number of batches that a pickup service will pick in 1 round of execution, such that 'batches picked up <=( max process capacity 'RUNNING state batches)'

 

  • Resume Service Configuration

Resume service, like pick up service, also runs as a scheduler service. This service also keeps an eye on BATCH_INSTANCE table. It picks the batches that are locked by another server instance which is not active now or has gone down (as detected by HeartBeat service). It takes a lock on those batches and resumes the workflow for them.

 

Configurable property Type
of value		 Value
options		 Description
dcma.resume.cronjob.expression String Any valid cron expression.
Default Value:
0 0/1 * ? * *
(For this value, resume service will be invoked every one minute.)		 This parameter specifies the schedule for which resume service will run. This is specified as a cron job expression.
server.instance.resume.capacity Integer Any Integer Value.
Default value: 4		 This parameter specifies the max number of batches that a resume service can pick at one go (i.e. in one iteration).

 

  • Other Configuration

Workflow configuration for deploying and sending mails when an error occurs in the workflow. When a batch instance goes into error, then a mail is sent via following configuration mentioned below:

 

Configurable property Type
of value		 Value
options		 Description
workflow.error.from_mail String Any valid email id.
Default Value: enterprise.support@ephesoft.com		 This parameter specifies the e-mail id from which the mail should be sent, when some error occurs during batch processing.
workflow.deploy String True
False
Default Value=true		 This parameter re-deploys all the available workflows in the system. Should be set only once during the new installations or upgrades.
workflow.error.subject String Valid e-mail subject.
Default Value: Error in workflow execution!!		 This parameter specifies the subject for mail to be sent when some error occurs during batch processing.
workflow.error.to_mail String Any valid email id.
Default Value:
enterprise.support@ephesoft.com		 This parameter specifies the e-mail id to which the mail should be sent when some error occurs while batch processing.
newWorkflows.basePath String Valid path of directory.
Default Value:
{Application}\\SharedFolders/workflows		 This parameter specifies the path where all jpdl(s) are placed when a new workflow or plugin is deployed.

 

  • WebService Configuration

These configurations should only be set in case of configuring Grid Computing workflow.

 

Configurable property Type
of value		 Value
options		 Description
wb.folderPath String Any valid path of ftp folder.
Default Value:
test		 This parameter specifies the folder path to be picked from the ftp location for processing batch in Grid Computing Batch Class.
wb.hostURL String Valid URL.
Default value:
http://localhost:8080/dcma/rest 		This parameter specifies the host URL for sending the batch instance from one Ephesoft instance to another.
dcma.batch.status.cronjob.expression String Any Integer Value.
Default value: 0 0/1 * ? * * 		This parameter specifies the schedule for fetching the batch instance status of remote batch instance executing on another Ephesoft instance server. This is specified as a cron job expression.

 

Dependency

For e-mail on error functionality, it depends on the mail configuration done in “mail.properties” property file.
