例: 公開時のデータのコピーの回避

このスクリプトは、データが公開時にサーバーにコピーされることを防ぎます。データのコピーを防ぐオプションは、ArcGIS 10.1 Service Pack 1 で使用可能になりました。

マップ ドキュメントなどのアイテムを ArcGIS Server で公開するときに、サーバーはドキュメントで参照されているすべてのデータ ソースについて、ArcGIS Server に登録されているかどうかを確認します。登録されていないソースのデータはデフォルトでサーバーにコピーされ、サーバー ディレクトリに配置されます。サーバー管理者は、データを登録する際にサーバーにデータセットが蓄積されないように、データがコピーされることを防ぐことができます。

このスクリプトをサーバーで一度実行するだけで、すべてのデータ コピーを防げます。
