無法發佈內容

Last update: Tue Jul 16 2024 00:00:00 GMT+0000 (Coordinated Universal Time)

將/var/structure從生產環境復寫到Stage，並在Stage Publishers上重新啟動AEM後，問題已解決。

說明 description

環境
Adobe Experience Manager (AEM)

問題
Stage發佈程式無法正常運作，您無法在此執行個體上發佈內容。

在error.log中會顯示這些型別的錯誤：

解決方法 resolution

記錄檔中的錯誤與快取無關，但是當服務使用者在作者或發佈者上沒有路徑/var/discovery的正確許可權時，就會顯示錯誤。

驗證/var/discovery路徑的許可權時，發現在Stage發行者上，/var下沒有discovery資料夾，並且也有許多遺漏的內容。

雖然生產發行者上的/var資料夾有超過20個子系，但Stage發行者上的/var資料夾只有2個：復寫和 sling。

將/var/structure從生產環境復寫到階段環境，並在Stage Publishers上重新啟動AEM後，問題已修正。
