Cache Page

The Cache page is part of the Administration perspective.

Overview

The Cache page offers an overview of all items currently stored in the system's cache and additional information about them. The information available here is useful for setting up your system's server input buffer sizes.

Functions

Automation Engine Cache: Information requested from the database is stored in the Server input buffer and can so quickly be read whenever required. This procedure improves system performance as it is less time-consuming than repeatedly calling the database.

Keep this in mind when specifying the maximum size of the server input buffer in the Processes & Usage Page page. The value depends on the memory that is available on your computer.

Where to find the page:

The Administration perspective is only available, if the user has the required privilege.

In the AWI open the Administration perspective.
In the Navigation pane to the left, find the entry Cache.
Click on its tab to open the Cache page table.

In the toolbar the default buttons Export to export the table content as .csv and Refresh are available.
