data_engine (test Connection string fails)

Products

• DX Unified Infrastructure Management (Nimsoft / UIM)

Issue/Introduction

After Database migration, test connection for data_engine fails:

 

Environment

Release : 20.4

Component : UIM - DATA_ENGINE

Cause

Port number for the new database service has changed

Resolution

Make sure that you are using the correct port number. After migration, especially to a different database vendor port number might change. 

1. Check if the port number that is used in probe configuration is opened - you can use telnet :

telnet <IP_address_of_DB_server> <port_number_of_db_service>

 

 

Additional Information

For more in-depth communication diagnosis, I suggest collecting the packet capture using tools like wireshark, tcpdump, tshark etc... It will allow you to eliminate basic connectivity problems, like port/IP address/ HOST/ firewall rules misconfiguration. 

Please refer to the following article, to get more details on how to use Wireshark:
