I am trying to connect my oracle cloud database using sqldeveloper with connection type basic but it fails connection with error:
Status : Failure -Test failed: IO Error: The Network Adapter could not establish the connection.
Anyone can help how can i connect my oracle db system using sqldevloper with connection type either basic or TNS ??
Have you tried to telnet the server on port 1521?
It sounds likely that the dbsystem is not connected to the internet.
Please check if the dbsystem subnet has:
Security List with a rule to allow port 1521 on your ip address
Routing Table that allows internet access via internet gateway
Am trying to connect vertica from DBeaver, but am getting below connection error. Initially it was working fine, but suddenly its throwing connection error.
Error Message:
[Vertica][VJDBC](100071) GSS authentication failed due to problems establishing a TGT with JAAS using configuration verticajdbc; reason: Message stream modified (41).
Message stream modified (41)
Message stream modified (41)
I am not able to establish the connection now. Can anyone please help me on it.
The main issue I see with vertica users struggling to connect relate to the drivers used or where the host has changed. Have you updated vertica recently or has there been a change to the host name are just a couple of things you should check.
Sorry I cant be more specific its hard to troubleshoot when I dont have all the information.
Thanks
I am getting the error as 'ORA-03135: connection lost contact' from my C# code while making connection to oracle DB. The same job works just fine from our test server. But it failed with ORA-03135: connection lost contact error from prod server.
The C# code use ODAC to connect to oracle DB.
Appreciate your inputs.
Thank you
This error is most likely caused by a firewall blocking the connection request. Check for any firewalls in your network or on the database server and make sure your access rules are configured correctly.

ORA-03135: connection lost contact tips
What can I do to avoid the ORA-03135 error?
Answer: The oerr utility shows this for the ORA-03135 error:
ORA-03135: connection lost contact
Cause:
1) Server unexpectedly terminated or was forced to terminate.
2) Server timed out the connection.
Action:
1) Check if the server session was terminated.
2) Check if the timeout parameters are set properly in
sqlnet.ora.
The ORA-03135 error is common when connecting remotely when a firewall
terminates the connection.
One solution for the ORA-03135 error is to increase the value of the
sqlnet.ora expire_time parameter in the sqlnet.ora file or to check
for a expire parameter in a SQL*Plus profile.
To diagnose the ORA-03135 error, start by checking to see if the OS
PID still exists, using the "ps -ef | grep" syntax.
Check to see if there is a Network Address Translation (NAT) between
the client and server
In Windows, check to see if a Windows firewall is checking for your
local connections.
...
Also, setting the parameters sqlnet.inbound_connect_timeout and
inbound_connect_timeout_listenername to 0 can stop the ORA-03135
error.

java.sql.SQLException: Io exception: The Network Adapter could not establish the
connection at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java)
I am getting this error when data in database is increased (nearly 3000). It works fine with limited data (say 100).
The Network Adapter could not establish the connection
Is typically thrown when
the Oracle listener is not running
the wrong hostname was specified in the connection url
the wrong port was specified in the connection url
the port is blocked by firewall
I have never seen it related to "increasing" the data in the database
