このスクリプト例は、テキスト ファイルから SD(サービス定義)ファイルのリストを読み取り、各 SD をサービスとして公開します。このスクリプトは特に研究室内の多数のコンピューターに同じサービスのセットを配置する場合や、開発サーバー、ステージング サーバー、および本番サーバー全体に配置を行う場合に有効です。
入力ファイルは次のような構造になります。
#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 - サービス定義ファイルのパス。この場所は、ArcGIS Server からアクセスできる必要がありますが、ArcGIS Server に登録されている必要はありません。
- folderName - サービスを格納する ArcGIS Server フォルダーの名前。フォルダーはすでに存在している必要があります。このプロパティを省略した場合、サービスはルート レベルで公開されます。
- serviceName - サービスの名前 (SD 内の名前を無効にする場合)。
スクリプトは最初に、指定したフォルダーにサービスが存在するかどうかを確認します。サービスが存在する場合は、サービスが削除されて再公開されます。したがって、テキスト ファイルには、配置するサービスを長いリストで指定することも、更新するサービスを 1 つだけ指定することもできます。
