Hi All,
I installed DB connect on my Heavy forwarder, no firewall running on my Splunk, and the Oracle database we are trying to connect requires firewall port to open. They opened the firewall port of database(bidirectional). Still, i am getting the following error:

com.zaxxer.hikari.pool.HikariPool$PoolInitializationException: Failed to initialize pool: IO Error: The Network Adapter could not establish the connection.

All answers are welcome.

Hi @aspirantsplonk,

Have you tried to check network connectivity from Heavy Forwarder to Oracle Database server ? You can check with telnet command for example telnet database_server_ip port
