How do you script out SQL Server agent jobs to single or individual files - sql-server

Question

I've tried various Powershell scripts but they fail with:
The following exception occurred while trying to enumerate the collection: "An exception occurred while executing a Transact-SQL statement or batch.".
At H:\Create_SQLAgentJobSripts2.ps1:89 char:22
foreach ($job in $s.JobServer.Jobs)
~~~~~~~~~~~~~~~~~
CategoryInfo : NotSpecified: (:) [], ExtendedTypeSystemException
FullyQualifiedErrorId : ExceptionInGetEnumerator
What has gone wrong or how can I get better debugging on this error?
I executed this script:
.\Create_SQLAgentJobSripts2.ps1 .\ServerNameList.txt
Here's the script
param([String]$ServerListPath)
#write-host "Parameter: $ServerListPath"
#Load the input file into an Object array
$ServerNameList = get-content -path $ServerListPath
#Load the SQL Server SMO Assemly
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.Smo") | Out-Null
#Create a new SqlConnection object
$objSQLConnection = New-Object System.Data.SqlClient.SqlConnection
#For each server in the array do the following.
foreach($ServerName in $ServerNameList)
{
Write-Host "Beginning with Server: $ServerName"
Try
{
$objSQLConnection.ConnectionString = "Server=$ServerName;Initial Catalog=CED_NCT_RESOURCE_TRACK;Persist Security Info=True;User ID=CEDNCTAdmin;Password=CEDNCTAdmin;"
Write-Host "Trying to connect to SQL Server instance on $ServerName..." -NoNewline
$objSQLConnection.Open() | Out-Null
Write-Host "Success."
$objSQLConnection.Close()
}
Catch
{
Write-Host -BackgroundColor Red -ForegroundColor White "Fail"
$errText = $Error[0].ToString()
if ($errText.Contains("network-related"))
{Write-Host "Connection Error. Check server name, port, firewall."}
Write-Host $errText
continue
}
# Won't be using this object again
Remove-Variable -Name objSQLConnection
#If the output folder does not exist then create it
$OutputFolder = ".\$ServerName"
if (!(Test-Path $OutputFolder))
{
write-host ("Creating directory: " + $OutputFolder)
New-Item -ItemType directory -Path $OutputFolder
}
else
{
write-host ("Directory already exists: " + $OutputFolder)
}
write-host "File: $(".\$OutputFolder\" + $($_.Name -replace '\\', '') + ".job.sql")"
# Connect to the instance using SMO
$s = new-object ('Microsoft.SqlServer.Management.Smo.Server') $ServerName
write-host ("SQL Server Edition: " + $s.Edition)
write-host ("SQL Agent ErrorLogFile: " + $s.JobServer.ErrorLogFile)
# Instantiate the Scripter object and set the base properties
$scrp = new-object ('Microsoft.SqlServer.Management.Smo.Scripter') ($ServerName)
write-host ("SCRP ToString():" + $scrp.ToString())
write-host ("Test scrp - Server: " + $scrp.Server)
#The next step is to set the properties for the script files:
$scrp.Options.ScriptDrops = $False
$scrp.Options.WithDependencies = $False
$scrp.Options.IncludeHeaders = $True
$scrp.Options.AppendToFile = $False
$scrp.Options.ToFileOnly = $True
$scrp.Options.ClusteredIndexes = $True
$scrp.Options.DriAll = $True
$scrp.Options.Indexes = $False
$scrp.Options.Triggers = $False
$scrp.Options.IncludeIfNotExists = $True
#Now, we can cycle through the jobs and create scripts for each job on the server.
# Create the script file for each job
foreach ($job in $s.JobServer.Jobs)
{
$jobname = $job.Name
write-host ("Job: " + $jobname)
$jobfilename = ($OutputFolder + "\" + $jobname + ".job.sql")
$scrp.Options.FileName = $jobfilename
write-host "Filename: $jobfilename"
#This line blows up
$scrp.Script($job)
}
}

Possibly you're not instantiating the Server object correctly. Try the following instead...
# Alternative 1: With servername and port, using Trusted Connection...
$ServerName = 'YourServerName,1433'
$ServerConnection = New-Object Microsoft.SqlServer.Management.Common.ServerConnection -ArgumentList #( $ServerName )
# Alternative 2: With an SqlConnection object
$SqlConnection = New-Object System.Data.SqlClient.SqlConnection
$SqlConnection.ConnectionString = "Server=$ServerName;Initial Catalog=CED_NCT_RESOURCE_TRACK;Persist Security Info=True;User ID=CEDNCTAdmin;Password=CEDNCTAdmin;"
$SqlConnection.Open() | Out-Null
$ServerConnection = New-Object Microsoft.SqlServer.Management.Common.ServerConnection -ArgumentList #( $SqlConnection )
# Then...
$Server = New-Object Microsoft.SqlServer.Management.Smo.Server -ArgumentList #( $ServerConnection )
$Server.JobServer.Jobs | ForEach-Object {
Write-Host "Job: $($_.Name)"
}
