Steps to Reproduce

1. Login to the AES portal.
2. Click Enterprise.
3. After loading the page click on any notification or alert.

Root Cause

On AES instance search indexing was enabled, hence the monitoring nodes were non-responsive.

Resolution

Perform the following local-change to disable the Indexing:

1. Disable search indexing and search functionality on AES by unchecking the main checkbox on the search landing page to "enable indexing".




2. Set the following dynamic system settings to false:

• indexing/distributed/enabled
• indexing/distributed/index_enabled
• indexing/distributed/search_enabled

3. Disable Pega-SearchEngine agent directly on the AES server which call the pzFTSIncrementalIndexer activity, but unchecking “Enable this agent” checkbox.
(Or )
Disable the indexing agent on AES instance from System Management Application (SMA).
