Pega - Operators and Access Groups Interview Q&A

What is the difference between Work group and Access Group?

A work group is an instance of the Data-Admin-WorkGroup class. A work group can identify a user who is a supervisor, together with a set of workers and workbaskets that report to that supervisor.

 An access group is an instance of the Data-Admin-Operator-AccessGroup class. Access groups make a set of RuleSet versions available to requestors.

Developers define access groups and associate an access group with each user (each Data-Admin-Operator-ID instance). Typically, multiple users are associated with or belong to one access group.

The access group associated with a user affects access control by determining:

·         The portal layout that a user sees first after logging in.

·         The local customization RuleSet name and RuleSet version. These usually are defaulted whenever this user creates a new rule instance.

·         The application rule for this user.

·         Optionally, the access roles available to this user.

How to associate an Operator with a workbasket?

In a work group, we can associate an operator with a manager and a workbasket.

 What are access roles and how they work at run time? Can we create our own Access Roles? If yes, explain with an example.

An access role is an instance of the Rule-Access-Role-Name class.

Use an access role name to convey permissions (capabilities) to a user or a group of users. Access roles can be referenced in requestor instances, Operator ID instances, in access group instances, in activities, and in queries.

At log in, the system assembles a set of roles for a user based on information in a user’s requestor instance, Operator ID instance, and the associated access group instance.

Access roles influence which classes a user can view, update, and delete, and so on through the Access of Role to Object and Access Deny rule types.

Example. Create an instance of Rule-Access-Role-Name. To grant access to a user for a particular class create an instance of Rule-Access-Role-Obj.

For each of the eight categories in the array, you can enter an Access When rule name or a numeric value between 1 and 5.

If at runtime, the production level of your Process Commander system is not greater than the numeric value, then users with the specified access role can perform the operation (on objects of that class). If an Access When rule evaluates to true at runtime, the users with the specified access role can perform the operation.

Production level is set in Data-Admin-System.

 What is a portal and how can it be customized for different users?

The Process Commander portals support two user communities:

·         The Developer portal provides an integrated work, test, and development environment to support application developers. Customization of the Developer portal is typically not necessary and ordinarily limited to menus and skins.

·         User portals support managers and users of applications workers, as they enter, update, and resolve work objects. User portals may be customized to reflect the terminology, layout, facilities and styles appropriate to each user community.

This Developer portal provides quick access to dozens of tools, wizards, reports, and other capabilities.

The appearance and function of our Process Commander portal depends on information in our access group which references a portal rule (Rule-Portal rule type)

We can create our own portals and define new gadgets (instances of Data-Gadget).

Data-Gadget contains simple HTML rules.. We can change the Pega Logo as well.

 Define access group and its functionality?

Access Group controls the security basing on the job functions.

It is instance of Data-Admin-Operator-AccessGroup.

Various aspects that can be controlled through access group are

  1. default and available types of works( also called as work pools ) ,
  2. Primary rulesets ( Access Control to rulesets),
  3. Assigned roles,
  4. Portal layout
  5. Default ruleset for making changes ( Default ruleset whenever the user creates/ saves as the rule )

 What is the order in which Rule set list is constructed?

Requestor, Organization, Division, Access Group is the order in which this list is constructed.

In access group, Application rule set list is in bottom and Production Rule set is on top of it. It follows Top-down approach.

 What is RuleSet?

A RuleSet name is an instance of the Rule-RuleSet-Name rule type. Each RuleSet defines a major subset of rules in the PegaRULES database, because every instance of every rule type references or “belongs to” a RuleSet. A RuleSet name is a major aspect in:

·         Access control

·         Grouping interrelated rules

·         Managing the rules

·         Moving applications — sets of rules — from one Process Commander system to another.

Process Commander itself consists of six standard RuleSets:

·         Pega-AppDefinition — Standard rules supporting Direct Capture of Objectives features

·         Pega-ProCom — Standard rules that support business process management (BPM) applications

·         Pega-IntSvcs — Standard rules that support integration

·         Pega-WB — Standard rules that support the portal infrastructure

·         Pega-RULES — Standard rules that support business rules engine and rule resolution

·         CheckInCandidates — Optional. Empty, used by rule check-in processing. Version 01-01-01 is not locked.

 Any application developer who can checked out rules has a private RuleSet.

The system creates each private ruleset automatically named to match the developer’s operator ID value.

We create one ruleset per application.

Rule set names are part of SysAdmin category.

 What is ruleset versioning? Explain Major, minor and patch?

A RuleSet version is an instance of the Rule-RuleSet-Version rule type. The version number in the form AA-AA-AA, defines six digits in three groups that characterize the evolution and development of a rule instance, and of the application it belongs with. The three segments are known as the major version, minor version, and patch version.

For eg. LoanAdmin:01-02-03

Here, 01: major version

02: minor version

03: patch version

Major : for entirely new functionalities or major releases, the first two digits of the version is incremented.

Minor : for enhancements, middle two digits are incremented.

Patch : for bug fixes, last two digits are incremented.

 Rule resolution algorithm uses version numbers to find the most appropriate single rule instances to execute in a specific situation.

 Few rules are non-versioned

Application, class, RuleSet. Ruleset version, Access deny, Library.

 Explain about RuleSet types and the priority given in Rule Resolution?

Application RuleSet is a RuleSet that appears in any of the following form fields:

·         On the General tab of the application rule referenced in the access group for a requestor (when the current work pool is part of this application)

·         (Recursively) On the General tab of a ‘parent’ application rule, if they Include Parent check box on the General tab of a ‘child’ application is checked.

·         In the Local Customization field on the Settings tab of the access group

 Production RuleSet is a RuleSet that has the Type field set to Standard (on the Category tab of the RuleSet form) and that typically has at least one open (not secured) RuleSet Version.

Production RuleSets are listed on the General tab of an application rule and on the Layout tab of the Access Group form

The application RuleSet does not include rules in RuleSets listed in the Production RuleSets array of the Access tab.

 During rule resolution, the system:

·         First priority given to Production Rulesets. First, search the rules in Rulesets available in Production RuleSet.

·         Next Searches the rules in the Rulesets listed in application Rulesets. First using the topmost RuleSet name and version on the list, then the next, and so on. Override RuleSet versions (the top layer are searched first; the Pega-RULES RuleSet is searched last)

·         Ignores any rule instances that match a RuleSet on the list but contain versions higher than the version on the list.
