What is grid Informatica?
A grid is an alias assigned to a group of nodes that allows you to automate the distribution of workflows and sessions across nodes. When you use a grid, the Integration Service distributes workflow tasks and session threads across multiple nodes. A Load Balancer distributes tasks to nodes without overloading any node.
Which Informatica services can be run on a grid?
The Integration Service distributes workflows across the nodes in a grid. It also distributes the Session, Command, and predefined Event-Wait tasks within workflows across the nodes in a grid. . The Integration Service distributes session threads across nodes in a grid.
What is Informatica PowerCenter grid processing?
When a PowerCenter domain contains multiple nodes, you can configure workflows and sessions to run on a grid. When you run a workflow on a grid, the Integration Service runs a service process on each available node of the grid to increase performance and scalability.
Can we assign repository service to grid?
Can a Repository Service run on a Grid? No, a Repository Service cannot run on a Grid. The Grid option is only available for the Integration Service and is not available for any other service.
What is workflow in Informatica?
A Workflow in Informatica is a set of multiple tasks connected with start task link and triggers the proper sequence to execute a process. When a workflow in Informatica is executed, it triggers a start task and other tasks connected in the workflow. A workflow is an engine which runs ‘N’ number of sessions / Tasks.
What is High Availability Informatica?
High availability eliminates a single point of failure in an Informatica domain and provides minimal service interruption in the event of failure. When you configure high availability for a domain, the domain can continue running despite temporary network, hardware, or service failures.
Which transformation can never be reusable?
If we change any properties of the transformation it will automatically reflects in the mapping transformations. Here source qualifier transformation is the transformation that cannot be reused.
What is reusable task in Informatica?
Reusable object in workflow manager are objects which can be reused in multiple workflows. For Example, if you have created a command task in task developer, then you can reuse this task in any number of workflows. You can add any no of tasks in a workflow.
What is a mapping in Informatica?
Mapping in Informatica is a structural flow of data from source to target through transformations (or) it is the pipeline which tells how to flow data from source to target. Mapping is one of the basic elements in Informatica code. A mapping with out business rules are know as Flat mappings.
What is repository in Informatica?
The repository stores information required to extract, transform, and load data. It also stores administrative information such as permissions and privileges for users and groups that have access to the repository. You administer the repository through Informatica Administrator and command line programs.
What is deployment group in Informatica?
Deployment groups in Informatica are used as containers that allow smart grouping of objects to facilitate the deployment between different folders, repositories, and environments.
What tasks are usable?
You can create three types of reusable tasks in task developer.
- Command task.
- Session task.
- Email task.
What is the smart grid and how does it work?
The smart grid is a planned nationwide network that uses information technology to deliver electricity efficiently, reliably, and securely. It’s been called “electricity with a brain,” “the energy internet,” and “the electronet.”
How is grid computing used in the industry?
In the industry and financial services, grid computing can be implemented to speed up the transaction of trade and shrunk any high volume of data. In the field of IT, Grid computing enables the possibility to carry over any critical missions and circumstances that might not permit any downtime at all.
Who is involved in the National Technology Grid?
Grid computing is being applied by the National Science Foundation’s National Technology Grid, NASA’s Information Power Grid, Pratt & Whitney, Bristol-Myers Squibb Co., and American Express.
Who are the major players in grid computing?
