I have a problem with connection to Performance Warehouse on Appmon.

Status: Unable to connect to Performance Warehouse. Server is trying to reconnect.

How to reestablish a connection to the warehouse without losing historical data?



Hello @Heloisa Bueno R.

Access the server.0.0. logs on the server to know the reason about this situation and also look for the repository logs for the same.




Hi Helosia,

The real time Measure data will be stored on the Dynatrace AppMon server for 11 Mins during the database connection down, if your PWH issue was more than that then there is a data loss for real time and there is no impact of the historical data which is stored already in database, if you re-establish a connection to the PWH and if it's successful then the real time data will be started storing in PWH.

Step 1: Click the test connection to make sure the DB is reachable from the AppMon server.

if you are receiving any error other than test successful, then verify the server logs..

Step 2: If the test is successful then click on Connect which establishes the PWH connection.

the problem is that the test button is not enabled

As from the snapshot I could see the AppMon server is trying to reconnect, you can disconnect the database which enables you the test connection and can establish the connection again..

after clicking on disconnect it will enable the test connection.

Click on the test conenction

once the test is successful it will enable the Connect button.

Click on Connect and it will establish the PWH connection



I took the test and received the following message:

"check connection to database server failed: ORA-00257: Archiver error. Connect AS SYSDBA only until resolved."

You need to engage the Oracle DBA admin, as this issue is on the database.
