Dieses Skript liest durch eine Textdatei mit einer Liste an Service-Definitionsdateien (SDs) und veröffentlicht jede SD als Service. Dies ist besonders nützlich, wenn Sie den gleichen Satz an Services auf mehreren Computern in einem Labor oder auf Entwicklungs-, Staging- und Produktionsservern bereitstellen möchten.
Die Eingabedatei sollte wie folgt strukturiert sein:
#SD|folderName|serviceName
SD=\\mylabserver\Yellowstone.sd|folderName=Parks|serviceName=Yellowstone
SD=\\mylabserver\Rainier.sd|serviceName=Rainier
SD=C:\data\BufferGP.sd|serviceName=BufferGeoprocessing
SD=C:\data\Arches.sd|folderName=Parks|serviceName=Arches- SD: Der Pfad zur Service-Definitionsdatei. Dieser Speicherort muss für ArcGIS for Server sichtbar sein, muss aber nicht bei dem Programm registriert sein.
- folderName: Der Name des ArcGIS for Server-Ordners, der den Service enthält. Der Ordner muss bereits vorhanden sein. Wenn diese Eigenschaft weggelassen wird, wird der Service auf Stammebene veröffentlicht.
- serviceName: Ein Name für den Service, wenn Sie den Namen in der SD überschreiben möchten.
Das Skript prüft zunächst, ob der Service im angegebenen Ordner vorhanden ist. Ist dies der Fall, wird er gelöscht und anschließend erneut veröffentlicht. Die Textdatei kann daher eine lange Liste an zu bereitstellenden Services oder nur einen zu aktualisierenden Service enthalten.
