To isolate database-related performance issues:

Investigate when the database is used most heavily (B): Understanding peak usage times can help pinpoint when the database is under the most strain. This information is crucial for identifying potential bottlenecks and optimizing performance.

Lower query-time-related alert thresholds (C): By lowering the alert thresholds for query times, you can capture more detailed information about slow-running queries, helping to identify and address inefficient database operations.

There are two primary methods to queue an item for processing in Pega:

Queue-for-processing method: This method is used within an activity to queue items for background processing.

Run in Background smart shape: This smart shape is used in the process flow to queue items for background processing efficiently.

The system will consider the assignments with urgency value equal to and greater than the specified value in the Operator rule. Once all assignments are processed from the work queue based on the threshold urgency value, the lower urgency assignments are then considered.

Urgency Thresholds: The system checks the urgency of assignments in each work queue. Assignments with an urgency equal to or greater than the threshold are considered first.

Get from Work Queues First: With this option selected, the system prioritizes processing work queues before considering individual workbaskets.

Lower Urgency Assignments: After processing assignments meeting the urgency thresholds, the system will then consider lower urgency assignments if there are no higher urgency tasks left.

ï‚· Service Request Processor for Asynchronous Processing:

Configuring a REST service to run asynchronously using a service request processor ensures that the service runs without making the external application wait. The system returns a unique identifier instantly and processes the request in the background.

ï‚· References:

Pega's best practices for REST services and asynchronous processing recommend using service request processors for handling long-running processes.

ï‚· Therefore, the correct answer is:

B. A REST service that runs asynchronously by using a service request processor.

ï‚· Job Scheduler with SendEmailNotification Utility:

Running a job scheduler to pull customer records matching the current date and using the SendEmailNotification utility ensures that emails are sent out at midnight. Recording failures in a data type captures the necessary error information.

ï‚· Job Scheduler with CorrNew Utility:

Using the CorrNew utility to send emails and record any exceptions in a data type also satisfies the requirement for recording email delivery failures.

ï‚· References:

Pega documentation on job schedulers and email utilities provides guidelines for implementing scheduled tasks and handling email delivery.

ï‚· Therefore, the correct answers are:

B. Run a job scheduler, and pull the customers that match the current date. For each record, invoke the SendEmailNotification utility. If any exception is received in email delivery, mark the failure in a data type.

D. Run a job scheduler, and pull the customers that match the current date. For each record, invoke the CorrNew utility. If any exception is received in email delivery, mark the failure in a data type.

The Skin rule in Pega is used to define the look and feel of the application. By configuring the importance field for each column included in a repeating layout, you can control how information is displayed on different devices. Additionally, specifying the width of the sidebar on desktops ensures that the application is optimized for various screen sizes and resolutions.References:

My Performance Details Report:

Use the My Performance Details report to get insights into the user’s session performance metrics.

Alerts Log:

Review the Alerts log for any alerts that were triggered during the user’s session that could indicate performance issues.

Continuous integration (CI) is a DevOps practice where developers frequently merge their code changes into a central repository, followed by automated builds and tests. The primary goal is to detect and address integration issues early.

Leveraging release toggles (Answer B):

Explanation: Release toggles (or feature toggles) are a technique to enable or disable features within a software application without deploying new code. This allows teams to integrate new features incrementally and safely, supporting continuous integration and delivery.

For back-to-back processing on the follow action form to ensure that getnextwork processing does not occur, configure it to "Look for the assignment to perform." This ensures that the system checks for the next assignment within the current context without moving to the next item in the work queue. References:
