SO WHEN PACKAGE EXECUTES IT LOOKS LIKE BELOW
if you want to see if both task diasble options are set to false then when package is executed the it will ook like below
DelayValidation:
Description: The DelayValidation property allows you to defer the validation of tasks and containers until the package is executed. This is useful when dealing with dynamic properties determined at runtime.
Example: Suppose you have a package with a connection manager where the connection string is set dynamically based on user input or a configuration file. By setting DelayValidation to True for the connection manager, the package will be validated even if the connection string is not available at design time.
Use Case: It is used when you have dynamic properties that are set during runtime and you want to avoid validation errors at design time.
Disable:
Description: The Disable property, when set to True, disables the execution of the package. This is helpful for debugging or when a package needs to be temporarily deactivated.
Example: If you have a package that you want to temporarily stop from running, you can set the Disable property to True. This ensures that the package won't execute until the property is set back to False.
Use Case: It is used when you want to temporarily stop a package from executing without removing it from the project.
DisableEventHandlers:
Description: The DisableEventHandlers property, when set to True, disables the execution of event handlers within the package. This can be used to bypass event handling logic for specific scenarios.
Example: Imagine a package with several event handlers (e.g., OnError, OnPreExecute). Setting DisableEventHandlers to True would prevent these event handlers from running, allowing the package to execute without invoking any associated event logic.
Use Case: It is used when you want to temporarily bypass event handling logic, for example, during testing or troubleshooting.
FailPackageOnFailure:
Description: When set to True, the FailPackageOnFailure property specifies that the package will fail if any of its tasks or containers fail during execution.
Example: If you have a package with multiple tasks, setting FailPackageOnFailure to True means that if any task fails (returns a failure result), the entire package will fail, and subsequent tasks will not execute.
Use Case: It is used when you want the package to fail as soon as any task or container fails, rather than continuing with subsequent tasks.
FailParentOnError:
Description: When set to True, the FailParentOnError property indicates that the parent container should fail if any of its child tasks or containers fail during execution.
Example: Consider a Foreach Loop Container with multiple tasks inside. If FailParentOnError is set to True and any of the tasks inside the loop fail, the entire loop container will fail, and subsequent iterations will not execute.
Use Case: It is used when you want a parent container to fail if any of its child tasks or containers fail, providing a way to handle errors at the container level.
1. MaxConcurrentExecutables:
Description: Specifies the maximum number of executables that can run concurrently in a package. An executable can be a task or a container.
Example:
Suppose you have a package with multiple data flow tasks and transformations. You set:
MaxConcurrentExecutables: 3
Use Case:
In this scenario, the package will only allow up to three executables to run at the same time. If there are more tasks or containers, they will be queued and executed once a slot becomes available. This can be useful to manage resource usage and optimize performance.
2. MaximumErrorCount:
Description: Sets the maximum number of errors allowed before the package execution fails.
Example:
Let's say you have a package processing files, and you expect occasional errors in the data. You set:
MaximumErrorCount: 10
Use Case:
If the package encounters more than 10 errors during execution, it will fail and stop processing. This can be helpful to prevent the package from continuing with potentially corrupt data.
3. PackagePriorityClass:
Description: Specifies the priority class of the package relative to other processes.
Example:
You have multiple packages scheduled to run on a server. You set:
PackagePriorityClass: BelowNormal
Use Case:
In a situation where resources are limited, the packages with higher priority classes will be given precedence over those with lower priority classes. This ensures critical processes get the resources they need.
These properties provide fine-grained control over how your SSIS packages are executed, allowing you to manage resources effectively and respond to different error scenarios. They are especially useful in complex ETL workflows where optimizing resource usage and handling errors is crucial.
Certainly! Let's delve deeper into each of the SSIS package execution properties:
1. MaxConcurrentExecutables:
Description: This property sets the maximum number of tasks or containers that can execute simultaneously within a package.
Example:
Imagine you have a package with five data flow tasks and you set MaxConcurrentExecutables to 2.
Use Case:
In this scenario, only two executables will run concurrently. If more than two executables are ready to run, the rest will wait in a queue. This is beneficial when you want to control the degree of parallelism in your package, managing resource utilization and optimizing performance.
2. MaximumErrorCount:
Description: This property determines the maximum number of errors the package can encounter before it fails.
Example:
Suppose you are processing data files, and you anticipate that up to 20 errors can occur. You set MaximumErrorCount to 20.
Use Case:
If the package encounters more than 20 errors during execution, it will terminate and report a failure. This is useful for preventing the package from proceeding with potentially corrupt or erroneous data.
3. PackagePriorityClass:
Description: This property defines the priority class of the package relative to other processes on the system.
Example:
You have several packages scheduled to run on a server, and you assign PackagePriorityClass as AboveNormal.
Use Case:
In an environment where resources are limited and shared with other processes, packages with higher priority classes will be allocated resources more aggressively. This ensures critical processes receive the necessary resources even in resource-constrained environments.
These properties grant you fine-grained control over the execution behavior of your SSIS packages, enabling you to effectively manage resources and respond to various error scenarios. They are particularly valuable in complex ETL workflows where optimizing resource usage and handling errors is paramount.
