Pre-requistie: Read introduction to Workflow Model
Workflow Modeler GUI
- Toolbars: Provide acess to commonly used features. All features are available through the menu system.
- Tree: Provides a method to quickly select any object (model, task, link, etc) by name. The selected object is highlighted in the digram.
- Properties: Display the property settigns for the currently selecteds object, and enables modification of property values if it is a read/write property
- Project pane: A visual representation of the workflow model. Using the toolbar, user can select new types of objects, drop it on the project pane and select the object to set their properties.
- All object names must be unique
- Link names are used as transition button labels
- Some object names are used as labels on UI form e.g. user, group and metadata task. ii) links with user, group, review or metadata predecessor
Review Task & Links
- Must have one sccess and one failure link
- May have additional default links, which will appear as additional transition options
- Success and failure link can have any name
- Use available groups and/or available user to define sets of possible reviwers for this task
- Then use Available Reviews to define the actual selection list of reviwers, which is use to generate a selection list on the job instantiation form
- Number of reviewers must be define in design time
- Use the Label and Description field to configure the form appearance of this select list
- Have Shared By property instead of an owner property. So enter a set of users and groups to send this task to.
- One of them will take ownership and perform the task
- Use to display the metadata input form but appearance will depend on its configuration setting.
- User then enters a metadata for the files in the workflow.
- Set immedate property to true to allow it to open the metadata form as soon as task becomes active
- Attempts to lock all job files associated with a workflow However it can't lock files that are already locked outside the workflow
- Has two transition, i.e. Success (taken when all locks are acquired) and failure (taken when any of the locks can't be acquired) which is required
- Can transfer between task owners for files locked within its own tasks
- Use external task calling unlock.ipl to unlock files
- Non interactive task that runs as an external application or script on TS server.
- Runs as SYSTEM user on windows OS or runs with userid of the task owner on UNIX server.
- Use the external task to execute unlock.ipl script to unlock files. Unlock.ipl does not acquire any arguments.
- Properties: i) Command - Full path of the executable or script to run ii)Retry - Successive attempts to re-run program again upon failure to start after a specific time whose value can be specified in iw.cfg
- When workflow calls external task program, it passes data as command line arguments, including job and task ID, area vpath and list of job files.
- A time delay task that transitions to other tasks after some amount of delay time or a specific time
- Use it in a time delay if a lock task fails, before it tries to lock the file again.
- Must have one timeout transition where the timeout transition's time delay can be absolute or relative.
- Any task can use one or more timeout links in addition to any other links.
- Used to copy files to another area but only files associated with the job are updated.
- Equivalent to Get Latest if source is a staging area or a Copy To if source is another workarea or an edition
- Area vpath is the destination area
- Properties: i) Delete - propagate deletion of fiels to destiniation area; ii) Overwrite - Overwrite conflicting versions in destination area; iii) Source Area VPath - area from which files are copied
- Use to send notification to users via email
- Generates a message notifying a user that a task has been assigned to them with information about that job
- Email command: $IW_HOME/iw-perl/bin/iwperl/
- Email body: author_iwmailbody.tpl
- Email body text: author_textbody.tpl
- Email header: author_iwmailheader.tpl
To configure and use email task you must:
- Identify compay'es SMPT server and domain name
- Configure iw.cfg file under [iwsend-mail] section
- Set up an email_map.cfg file in iwhome/local/config/wft/solutions folder
- Variables allow the job creator to enter workflow or task property values when the job is created
- It can be used as property values for any object types
- There are 7 variable types:
1. Configurable variable: Value entered by the job creator via the form when the job is started. Configurable variables can be local to an object or global to the entire worflow model.
- Use local variables when you want to enable the job creator to select a specific task owner, area vpath or other single property of one task.
- If a value will be used in more than one task, use global property
- To define local configurable variable: Select a task object proeprty->description. Then select "configurable" from variable type drop down list. Enter a label value (will be displayed on the instantiation form). Entering and ID is optional as system will automatically generate a unique ID Recommend leave this default value for local variable. Description field is use for displaying a tooltip help icon. Click OK button
- To define global configurable variable: Select workflow object property->global variable. Then select "configurable" from variable type drop down list. Enter a unique ID value. Enter a label value. Click Add button. When finish click OK button.
2. System variable: Dynamic value which is automatic created and set by the workflow system, when a workflow starts. Can use it as default or property values. All system variable name are uppercase and begin with "$IW_"
4. Datasource variable: Vaue calculated by an external Java class.
5. Extended attribute variable: Used to set extended attribute data on files.
6. Macro variable: Values used to set extended attribute during workflow.
7. Task variable: Used to pass data along from one task to another task as a job executes.
