IICS informatica interview questions-Part1
20. How many Status states are available in IICS monitor? The various status states available in IICS areStarting: Indicates that the task is starting.Queued: There is a predefined number set which controls how many tasks can run together in your IICS org. If the value is set to two and if two jobs are already running, the third task you trigger enters into Queued state.Running: The job enters the Running status from Queued status once the task is triggered completely.Success: The task completed successfully without any issues.Warning: The task completed with some rejects.Failed: The task failed due to some issue.Stopped: The parent job has stopped running, so the subtask cannot start. Applies to subtasks of replication task instances.Aborted: The job was aborted. Applies to file ingestion task instances.Suspended: The job is paused. Applies to taskflow instances.
9. What is a taskflow in Informatica Cloud? A Taskflow is analogous to a workflow in Informatica Powercenter. A taskflow controls the execution sequence of a mapping configuration task or a synchronization task based on the output of the previous task. To create a taskflow, you must first create the tasks and then add them to a taskflow. The taskflow allows you to → Run the tasks sequentially → Run the tasks in parallel → Make decisions based on outcome from one task before triggering the next task.
14. What is Dynamic Linking? Informatica Cloud Data Integration allows you to create a new target files/tables at runtime. To use this feature in mappings, choose Create New at Runtime option in target and specify the name for the new target. The user can choose a static filename where the target file will be replaced by a new file every time the mapping runs. The user can also choose to create a Dynamic filename so that the every time the mapping runs, target file is created with a new name.
5. What is the difference between a Synchronization task and Replication task? One of the major differences between a Synchronization task and a Replication task is that, in a synchronization task, you can transform the data before loading it to the target. However, in a Replication task, you can replicate the data from source to target without transforming the data. A Replication task can replicate an entire schema and all the tables in it at a time which is not possible in Synchronization task. A Replication task comes with a built-in incremental processing mechanism. In Synchronization task user needs to handle the incremental data processing.
25. What system variables are available in IICS to perform Incremental Loading? IICS provides access to following system variables which can be used as a data filter variables to filter newly inserted or updated records.$LastRunTime returns the last time when the task ran successfully.$LastRunDate returns only the last date on which the task ran successfully. The values of $LastRunDate and $Lastruntime get stored in Informatica Cloud repository/server and it is not possible to override the values of these parameters. These parameters store the datetime value in UTC time zone.
Informatica Cloud Interview Questions and Answers
Informatica Cloud is an ETL and Integration platform providing a web interface to the web developers to access administrator and monitor the tasks by using that web interface. It helps the developers build the solutions that perform the ETL processes between the cloud and on-site solution.
To your beginning menu(you may locate the begin start menu in the all-time low left of your computer system display screen).
Mapping is just a team of targets that are concatenated through a group of changes. These improvements have procedures describing data circulation and just how the data is filled within the aims for.
Cloud developers may be thought of as an equivalent version of PowerCenter professionals. Using Cloud developer, one may conveniently set up applying that are actually in theory comparable to exactly how PowerCenter applying are set up. In Cloud professionals, one can quickly likewise improve data utilizing articulation transformation, Filter transformation, and numerous others.
Activity log: The work particulars of the task log have come back in this particular variable.
Schedule: The routine’s particulars are returned, and it likewise assists in making or even upgrading the timetables.
You can use a Replication activity to reproduce data from a database table or an on-premise program to a target. Using the built-in progressive processing method of the Replication Task, you can select to repeat all the source rows or only the rows that have changed since the last running of the task.
In earlier variations of Informatica Cloud, the Union transformation makes it possible for merely a pair of groups to be specified; hence if three different basis teams need to be mapped to aim, the individual needs to use two Union improvements. The result of the initial pair of groups to Union1. The production of Union1 as well as group3 to Union2.
When Source is configured, create the application with the fundamental resource desk to disperse the areas to downstream transformations. Use Named Fields as the Field Selection Criteria after Input in the below improvement, then comprise all the essential fields in the Incoming Fields portion of the switch. After that, transform the Source contest into a specification. The resource fields are still preserved in the downstream change when the places are not on call in the source makeover after parameterizing the Source.
The Cloud server/repository stores all of the info. Unlike Powercenter, all information in Informatica Cloud is saved on an Informatica-managed server. The repository database is not accessible to the user. As a result, retrieving data from metadata tables via SQL queries is not available, as it is in the Informatica Power center.
The records can quickly be approved from one Mapping task to an additional in Informatica Cloud Data Integration during a Task flow with parameters. The Mapping Task, which provides the data, ought to possess an In-Out Parameter defined utilizing Set Variable functions. The Mapping Task which obtains the information ought to either include an Input guideline or an In-Out Parameter specified in the mapping to review the data conceded from the upstream job.
