- SleepStatusFail: This status indicates that the “Sleep” method failed to execute as expected. It might occur if there are issues with the time delay configuration, resource constraints, or other factors.
Q32. What do you understand by Locking in Pega? Explain the different types of Locking in Pega.
Ans: In Pega, locking is a mechanism that prevents multiple users or processes from simultaneously modifying the same data, ensuring data consistency and integrity.
Locking is essential in a multi-user environment to avoid conflicts and data corruption. Pega offers different types of locking, including:
- Optimistic Locking: In optimistic locking, a record is not locked for editing; instead, it associates a version number or timestamp with the record. When a user retrieves a record for editing, Pega checks if the version number or timestamp matches the current state of the record when the user attempts to save changes.
- Pessimistic Locking: Pessimistic locking explicitly locks a record for editing by a user and prevents other users from accessing it until the user releases the lock.
- Shared Locking: Shared locking allows multiple users to access and view a record simultaneously. Pega will then detect and prompt users to resolve these conflicts.
Q33. What is the difference between obj-list and rdb-list?
Ans: In Pega, obj-list and rdb-list are two methods for retrieving data from the application’s database. They differ in terms of their functionality and use:
|Aspects||obj-list (Object List)||rdb-list (Relational Database List)|
|Purpose||The obj-list method retrieves a list of instances (objects) of a specific class from the application’s database.
It queries the primary table associated with the class and returns a list of objects that meet specific criteria.
|The rdb-list method retrieves data from external relational database tables not necessarily associated with Pega classes.
It allows you to run SQL queries against external databases and retrieve data.
|Usage||Typically, one uses an obj-list to retrieve instances of Pega classes, making it useful for tasks such as displaying lists of cases or work items in a user interface.||People primarily use RDB-list when they need to access and work with data stored in external databases, such as customer data, product information, or other non-Pega data.The choice between the two methods depends on the source of the data and the requirements of the task at hand.|
