function Restart-JS7ControllerInstance { <# .SYNOPSIS Restarts a JS7 Controller Instance and optionally performs cluster fail-over .DESCRIPTION A JS7 Controller instance is restarted. In a JS7 cluster by default a fail-over to the standby cluster member is performed. The following REST Web Service API resources are used: * /inventory/releasable .PARAMETER Url Optionally the Url of the Controller to be restarted can be specified. Without this parameter the active Controller instance will be restarted. Consider that restarting a standby Controller instance in a JS7 cluster does not perform a fail-over operation. .PARAMETER Action Restarting a Controller instance includes the following actions: * Action 'terminate' (Default) ** no new tasks are started. ** running tasks are continued to complete: *** shell jobs will continue until their normal termination. *** API jobs complete a current process step. ** JS7 Controller terminates normally. * Action 'abort' ** no new tasks are started. ** any running tasks are killed. ** JS7 Controller terminates normally. .PARAMETER NoFailover This switch prevents a fail-over to happen when restarting the active Controller instance in a cluster. Instead, the restarted Controller instance will remain the active cluster member. .PARAMETER Service Retarts the JS7 Windows service. Without this parameter being specified JS7 will be started in its respective operating mode, i.e. service mode or dialog mode. .PARAMETER AuditComment Specifies a free text that indicates the reason for the current intervention, e.g. "business requirement", "maintenance window" etc. The Audit Comment is visible from the Audit Log view of JOC Cockpit. This parameter is not mandatory, however, JOC Cockpit can be configured to enforce Audit Log comments for any interventions. .PARAMETER AuditTimeSpent Specifies the duration in minutes that the current intervention required. This information is visible with the Audit Log view. It can be useful when integrated with a ticket system that logs the time spent on interventions with JS7. .PARAMETER AuditTicketLink Specifies a URL to a ticket system that keeps track of any interventions performed for JS7. This information is visible with the Audit Log view of JOC Cockpit. It can be useful when integrated with a ticket system that logs interventions with JS7. .EXAMPLE Restart-JS7ControllerInstance Terminates and restarts the JS7 Controller. In a cluster the active cluster member is restarted and a fail-over takes place to the standby cluster member. Use -of the -NoFailover switch prevents the switch-over. .EXAMPLE Restart-JS7ControllerInstance -Url (Get-JS7ControllerStatus).Active.Url Retarts the JS7 Controller active cluster member or standalone instance. .EXAMPLE Restart-JS7ControllerInstance -Url (Get-JS7ControllerStatus).Passive.Url -NoFailover Restarts the JS7 Controller standby cluster member. Consider use of the -NoFailover switch as a standby cluster member cannot switch-over to an active cluster member. .EXAMPLE Restart-JS7ControllerInstance -Service Retarts the JS7 Controller Windows service. .LINK about_JS7 #> [cmdletbinding(SupportsShouldProcess)] param ( [Parameter(Mandatory=$False,ValueFromPipeline=$False,ValueFromPipelinebyPropertyName=$False)] [Uri] $Url, [Parameter(Mandatory=$False,ValueFromPipeline=$False,ValueFromPipelinebyPropertyName=$False)] [ValidateSet('terminate','abort',IgnoreCase = $False)] [string] $Action = 'terminate', [Parameter(Mandatory=$False,ValueFromPipeline=$False,ValueFromPipelinebyPropertyName=$False)] [switch] $NoFailover, [Parameter(Mandatory=$False,ValueFromPipeline=$False,ValueFromPipelinebyPropertyName=$False)] [switch] $Service, [Parameter(Mandatory=$False,ValueFromPipeline=$False,ValueFromPipelinebyPropertyName=$True)] [string] $AuditComment, [Parameter(Mandatory=$False,ValueFromPipeline=$False,ValueFromPipelinebyPropertyName=$True)] [int] $AuditTimeSpent, [Parameter(Mandatory=$False,ValueFromPipeline=$False,ValueFromPipelinebyPropertyName=$True)] [Uri] $AuditTicketLink ) Begin { Approve-JS7Command $MyInvocation.MyCommand if ( !$AuditComment -and ( $AuditTimeSpent -or $AuditTicketLink ) ) { throw "$($MyInvocation.MyCommand.Name): Audit Log comment required, use parameter -AuditComment if one of the parameters -AuditTimeSpent or -AuditTicketLink is used" } } Process { if ( $PSCmdlet.ShouldProcess( 'controller', 'Stop-JS7ControllerInstance' ) ) { Stop-JS7ControllerInstance -Url $Url -Action $Action -Restart -NoFailover:$NoFailover -Service:$Service -AuditComment $AuditComment -AuditTimeSpent $AuditTimeSpent -AuditTicketLink $AuditTicketLink } } } |
