Looking for help with add_persistence_profile

Question

All,&nbsp;
Looking for an example on how to add a default persistence profile to a virtual server. I see the example in the api doc, just not exactly sure how I set the profile.&nbsp;
add_persistence_profile( &nbsp;
    in String [] virtual_servers,&nbsp;
    in LocalLB__VirtualServer__VirtualServerPersistence [] [] profiles&nbsp;
);&nbsp;
 &nbsp;
Currently doing my work in powershell, but will take any language example.&nbsp;
&nbsp;
Thanks.&nbsp;
 &nbsp;

Java example:

String persistenceProfile = the_persistence_you_want;
LocalLBVirtualServerVirtualServerPersistence[][] persistence_profiles = new LocalLBVirtualServerVirtualServerPersistence[1][1];
LocalLBVirtualServerVirtualServerPersistence localPersistence = new LocalLBVirtualServerVirtualServerPersistence();
localPersistence.setProfile_name(persistenceProfile);
localPersistence.setDefault_profile(true);
persistence_profiles[0][0] = localPersistence;

iControlInterfaces.getLocalLBVirtualServer().add_persistence_profile(virtualServers,persistence_profiles);

All: 
  
 Does anyone have an example of implemting add_persistence_profile in PowerShell? This snippet below is loosely based upon this sample: https://devcentral.f5.com/wiki/iControl.PsProvisionVEForLocalDev.ashx 
  
 Example: 
  
 $Persistence = New-Object -TypeName iControl.LocalLBVirtualServerVirtualServerPersistence; 
 $Persistence.profile_name = "dest_addr" 
 $Persistence.default_profile = $true; 
 $Pers_ProfileA = (, $Persistence); 
 $Pers_ProfileAofA = (, $Pers_ProfileA); 
  
 Try { 
 (Get-F5.iControl).LocalLBVirtualServer.add_persistence_profile(($name, $Pers_ProfileAofA)); 
 } 
 Catch { 
 Write-Host "Error - Adding Persistence Profile! - Exception - $_.exception" -ForegroundColor Red 
 } 
  
 I receive the following exception: Cannot find an overload for "add_persistence_profile" and the argument count: "1" 
  
 Any pointer would be great...I have searched all over the place and the only sample that comes close is the Java one listed here. 
  
 Thanks!

That looks close, but not quite there.&nbsp;
The function looks like this&nbsp;
add_persistence_profile(string [] virtual_servers, LocalLB.VirtualServer.VirtualServerPersistence [] [] profiles)&nbsp;
The extra parentheses around the parameters are converting the two parameters into a single array parameter.&nbsp;
Try changing the function call to&nbsp;
(Get-F5.iControl).LocalLBVirtualServer.add_persistence_profile( (, $name), $Pers_ProfileAofA);&nbsp;
That will convert the virtual_servers parameter into a string array, and leave the second parameter correct.&nbsp;
Note, I haven't tried this, but I believe it should work.&nbsp;

After taking a fresh look today, it appears to be a syntax error that caused the iControl interface to throw an exception the lead me down the wrong path. This works now :-) 
&nbsp;  
&nbsp;  
&nbsp;  Set Source Address Affinity - so called "sticky session" 
&nbsp; $Persistence = New-Object -TypeName iControl.LocalLBVirtualServerVirtualServerPersistence; 
&nbsp; $Persistence.profile_name = 'source_addr' 
&nbsp; $Persistence.default_profile = $true 
&nbsp; $Pers_ProfileA = (, $Persistence); 
&nbsp; $Pers_ProfileAofA = (, $Pers_ProfileA); 
&nbsp;  
&nbsp; Write-Host "Enabling Source Address Affinity on Virtual Server `"$name`"..."; 
&nbsp;  
&nbsp; Try { 
&nbsp; (Get-F5.iControl).LocalLBVirtualServer.add_persistence_profile($name, $Pers_ProfileAofA) 
&nbsp; } 
&nbsp; Catch { 
&nbsp; Write-Host "Error - Adding Persistence Profile! - Exception - $_.exception" -ForegroundColor Red 
&nbsp; Write-Host "Message - $_.exception.message" -ForegroundColor Red 
&nbsp; Write-Host "Deleting VS: $name" 
&nbsp; (Get-F5.iControl).LocalLBVirtualServer.delete_virtual_server(($name)) 
&nbsp; } 
&nbsp; } 
&nbsp; Else 
&nbsp; { 
&nbsp; Write-Host "Error - VS Name Already Exists - $name" 
&nbsp; } &nbsp;
