Start-DbaAgentJob

Synopsis

Starts SQL Server Agent jobs and optionally waits for completion

Description

Starts one or more SQL Server Agent jobs that are currently idle. This function validates jobs are in an idle state before starting them and can optionally wait for job completion before returning results. You can start all jobs, specific jobs by name, or exclude certain jobs from execution. It also supports starting jobs at specific steps rather than from the beginning, which is useful for resuming failed jobs or testing individual job steps.

Examples

Example: 1

PS C:\> Start-DbaAgentJob -SqlInstance localhost

Starts all running SQL Agent Jobs on the local SQL Server instance

Example: 2

PS C:\> Get-DbaAgentJob -SqlInstance sql2016 -Job cdc.DBWithCDC_capture | Start-DbaAgentJob

Starts the cdc.DBWithCDC_capture SQL Agent Job on sql2016

Example: 3

PS C:\> Start-DbaAgentJob -SqlInstance sql2016 -Job cdc.DBWithCDC_capture

Starts the cdc.DBWithCDC_capture SQL Agent Job on sql2016

Example: 4

PS C:\> $servers | Find-DbaAgentJob -IsFailed | Start-DbaAgentJob

Restarts all failed jobs on all servers in the $servers collection

Example: 5

PS C:\> Start-DbaAgentJob -SqlInstance sql2016 -AllJobs

Start all the jobs

Example: 6

PS C:\> Start-DbaAgentJob -SqlInstance sql2016 -Job @('Job1', 'Job2', 'Job3') -Wait

This is a serialized approach to submitting jobs and waiting for each job to continue the next.
Starts Job1, waits for completion of Job1
Starts Job2, waits for completion of Job2
Starts Job3, Waits for completion of Job3

Example: 7

PS C:\> Start-DbaAgentJob -SqlInstance sql2016 -Job @('Job1', 'Job2', 'Job3') -Wait -Parallel

This is a parallel approach to submitting all jobs and waiting for them all to complete.
Starts Job1, starts Job2, starts Job3 and waits for completion of Job1, Job2, and Job3.

Example: 8

PS C:\> Start-DbaAgentJob -SqlInstance sql2016 -Job JobWith5Steps -StepName Step4

Starts the JobWith5Steps SQL Agent Job at step Step4.

Required Parameters

-SqlInstance

The target SQL Server instance or instances.

-InputObject

Accepts SQL Agent job objects from the pipeline, typically from Get-DbaAgentJob or other dbatools functions.
Use this when chaining dbatools commands together to start jobs that meet specific criteria, such as failed jobs or jobs with certain schedules.

Optional Parameters

-SqlCredential

Login to the target instance using alternative credentials. Accepts PowerShell credentials (Get-Credential).
Windows Authentication, SQL Server Authentication, Active Directory - Password, and Active Directory - Integrated are all supported.
For MFA support, please use Connect-DbaInstance.

-Job

Specifies the names of specific SQL Agent jobs to start. Accepts job names as strings and supports multiple job names in an array.
Use this when you need to start only certain jobs instead of all jobs on the server. Job names are case-sensitive and must match exactly.

-StepName

Specifies the job step name where job execution should begin instead of starting from the first step.
Use this to resume a failed job at a specific step or to test individual job steps without running the entire job sequence.

-ExcludeJob

Specifies job names to exclude from starting when using -AllJobs or when no specific jobs are specified.
Use this to start all jobs except certain ones, such as excluding maintenance jobs during business hours or problematic jobs that need special handling.

-AllJobs

Starts all SQL Agent jobs that are currently in an idle state on the target instance.
Use this switch when you need to start all available jobs, typically after server maintenance or during bulk job execution scenarios.

-Wait

Waits for each job to complete execution before returning results or proceeding to the next job.
Use this when you need to ensure job completion before continuing your script, or when jobs have dependencies that require sequential execution.

-Parallel

Starts all specified jobs simultaneously and waits for all to complete, rather than starting and waiting for each job sequentially.
Use this when jobs can run concurrently without conflicts to reduce total execution time. Requires the -Wait parameter to function.

-WaitPeriod

Sets the polling interval in seconds for checking job status when using the -Wait parameter. Defaults to 3 seconds.
Adjust this value based on your job duration - use shorter intervals for quick jobs or longer intervals for jobs that run for hours to reduce server load.

-SleepPeriod

Sets the initial wait time in milliseconds after starting a job before checking its status. Defaults to 300 milliseconds.
Increase this value if you experience issues with jobs not showing as started immediately, which can occur on heavily loaded servers.

-EnableException

By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
This avoids overwhelming you with “sea of red” exceptions, but is inconvenient because it basically disables advanced scripting.
Using this switch turns this “nice by default” feature off and enables you to catch exceptions with your own try/catch.

-WhatIf

If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run.

-Confirm

If this switch is enabled, you will be prompted for confirmation before executing any operations that change state.
