Hi Harsha, 1.I have a query that we get to hear that all deferred saves will be commit to DB in next commit operation. Could you pls lef me know the rule which is responsible for doing that. ex: obj-save without write now... Which rule is responsible for commiting to DB and if we use obj-save-cncel or rollback how system get list of uncommitted rules .. Please help me.
In Pega, deferred saves are related to the Deferred Processing feature, and they involve committing changes to the database at a later point in time. When you perform a save operation (like `obj-save` without "write now"), Pega defers the write to the database until the next commit operation. ### Deferred Save and Commit in Pega: 1. **Deferred Save:** - When you perform an operation like `obj-save` without specifying "write now," changes are not immediately written to the database. - Instead, these changes are temporarily stored in memory as part of the clipboard pages. 2. **Commit Operation:** - The actual commit to the database happens during the next commit operation. - This can be an explicit commit operation, such as `commit` in an activity, or an implicit commit when transitioning from one transaction to another (e.g., when transitioning from one assignment to another). ### Relevant Rule for Committing to the Database: The specific rule responsible for committing changes to the database is the **Transaction** rule. The Transaction rule defines the scope and characteristics of a transaction, including when changes should be committed. - In the context of a flow action or an activity, the commit might happen implicitly when the flow action completes or when the activity finishes execution. ### `obj-save-cancel` or Rollback: - If you use `obj-save-cancel` or perform a rollback operation, the changes that were deferred and not yet committed to the database will be discarded. - Rollback operations typically discard any uncommitted changes made during the current transaction. ### Identifying Uncommitted Rules: Pega internally keeps track of the changes made to the clipboard pages during a transaction. When you perform a commit, Pega knows which changes need to be written to the database. If you want to understand the changes that are pending to be committed, you can use debugging tools such as: - **Clipboard Tool:** Inspect the clipboard pages to see the changes that are not yet committed. - **Tracer:** Use the Tracer tool to trace the execution of activities and observe the deferred changes.
Hello Sir, while designing a service rule how can we make sure to send the response only to authentic system/requests? Also, please make a video on Authentication Profile used in Integration rules.
Hi Aakash, In order to send response to authenticated system. We need to create an authenticated service from our end. When we expose our service to third party requestors, we should provide service credentials to them. While the third party companies send their request, we need to verify the credentials at our end, to make sure it is authenticated. that's how we can achieve it.
Hi Harsha, I have few questions like 1) In the flow there are 2 assignments when the 1st assignment submits, 2nd assignment should also be submitted. How to handle this. 2) In the UI I have 15 dropdowns and each dropdown should be populated without any performance issue. 3) For Team Leaders Manager worklist should not be show and for managers all the team members worklist should be displayed how to achieve this. 4) Any issue faced in services connectors and resolution of that.
Hi , Yes they removed it only when in case you create a flow in the case type class. But when you create flow in Class group it is still there.... They removed it considering the fact the case type flows does not need it, as there was a screen flow which was made as a mandatory starting flow. Also, work object is not getting created by started flow instead it is being done by directly calling ADD activity when case type starts.

Hi , I have a question about keys. One interviewer asked about keys. What keys used in my application. What types of keys we use in application? Looking forward for your reply. Thanks in advance
hi Sathya, I think the question is about the types of keys like class key and primary key... If this does not answer your question, please post the question with more details, we are happy to help you.
Hi Harsha, Could you please help me for these below questions. 1. How to capture child activity error in parent activity. 2. There is Grid in UI where RD is the source.. It is too slow while displaying data. Please let me know what could be reason and how we can trace these issues. 3. What should we do when neither operators nor system administrators are able to access the Prod application(SSO or non-SSO). 4 . Normal error handling in activities /connectors. Thanks G SHANMUKh
### 1. In Pega, you can capture errors from a child activity within a parent activity using a Try-Catch method. Here's an example of how you can achieve this: In this example: - The `try` block contains the code that calls the child activity (`tools.callActivity("ChildActivity")`). - If an exception occurs during the execution of the child activity, it will be caught by the `catch` block. - You can then handle the exception within the `catch` block. In this example, the error message is retrieved using `e.getMessage()`, and you can log it or take other appropriate actions. You can customize the error-handling logic based on your requirements, such as logging the error, updating properties, or displaying a user-friendly message. Remember to replace "ChildActivity" with the actual name of your child activity. This approach helps you ensure that errors in the child activity are captured and can be handled appropriately within the context of the parent activity. ### 2. Slow Grid with Report Definition (RD) as the source: To address a slow grid in Pega with an RD as the source, you can take the following steps: - **Optimize RD:** - Review the RD and optimize it to fetch only the necessary data. Avoid fetching unnecessary columns. - **Indexing:** - Ensure that the columns used in filtering and sorting in the RD are indexed in the database. - **Clipboard Tool:** - Use the Clipboard tool to trace and analyze the data being loaded onto the clipboard. Check if excessive data is being fetched. - **Tracer:** - Use the Tracer tool to trace the rendering of the grid. Look for slow steps and identify areas for optimization. - **Database Query Performance:** - Analyze the performance of the underlying database queries. Use database profiling tools if necessary. - **Caching:** - Check if caching strategies can be applied to the RD or data pages to improve performance. ### 3. Operators and System Administrators unable to access Prod application: If neither operators nor system administrators can access the Prod application, consider these steps: - **Check System Availability:** - Ensure that the Pega platform and associated services are running. - **Logs:** - Review Pega logs and system logs for any error messages or issues during startup. - **Database Connectivity:** - Verify the connectivity to the database. Check if the database server is accessible. - **SSO Configuration:** - If SSO is involved, ensure that the SSO configuration is correct and the identity provider is accessible. ### 4. Normal error handling in activities/connectors: In Pega, you can handle errors in activities and connectors using the Try-Catch method, as shown in the first answer. Additionally: - **Connect-Exception Class:** - When using Connectors, Pega provides a `Connect-Exception` class that can be used to catch and handle connector-related exceptions. - **Logging:** - Use the `tools.getLogger()` method to log errors and information for debugging purposes.
Hello, Yes, Pega offers an Out-of-the-Box (OOTB) control called "pxCheckbox" for selecting multiple checkboxes individually rather than using a multiselect control. The "pxCheckbox" control allows users to select or deselect multiple options by clicking on individual checkboxes. To use the "pxCheckbox" control: 1. In the section or harness where you want to include the checkboxes, add a "pxCheckbox" control from the control palette. 2. Configure the properties of the "pxCheckbox" control, such as the source of options, label, and value. 3. Map the control to a property in your data model to store the selected checkbox values. By using the "pxCheckbox" control, users can select multiple options independently, providing more flexibility compared to a multiselect control. If you have any further questions or need assistance with implementing the "pxCheckbox" control, feel free to ask!
Hi Harsha. I have one question. Can we create a flow in organization class? And what is the use of Activity or data transform calling in a flow action?
