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'm using nifi in version 1.14.0 and facing a very weird situation.
I have a loadbalanced connection and after disconnection in the cluster (due to out of memory errors)
I'm getting the following error:
Error load balance server -
standartLoadBalanceProtocol attempted to receive flowfile from peer for connection with id xxx but no connection exists with that ID
Did anyone experience anything familiar? Thanks for the help!
I think it relates to this ticket https://issues.apache.org/jira/plugins/servlet/mobile#issue/NIFI-9695. Please upgrade to NiFi version 1.16 and see if this error happens again.

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.
I am trying to connect to the database. but every time i try this error pop up :
Connection to Oracle - #obelix.fri.uniza.sk failed.
[08000][17410] No more data to read from socket
I tried everything what i found on the internet.
I think problem is in my computer, because from another one i can acces exactly the same database
we have a dot net application and it connecting to Oracle and fetching data and moving to SQL server. it was working very fine. just started giving error ORA-12560: TNS:protocol adapter error . Tnsping also giving this error. but if i stop this application and tnsping then its success. again starting the application on the first 10 minutes its working perfectly and gain giving same error. every 5 seconds this application connecting to Oracle databse.
any idea what is this error; and how to resolve. there is lots of questions over here,but didnt find a soulution .
highly appreciate your comments against this query
It seems you have some sort of resource leak. Do you close connections properly ?
Also, as ar said in comment, why don't you just keep this connection open ? IIRC Establishing conn is costly operation in any DBMS.
Also, from documentation:
ORA-12560 -- TNS:protocol adapter error
Cause: A generic protocol adapter error occurred.
Action: Check addresses used for proper protocol specification. Before reporting this error, look at the error stack and check for lower level transport errors. For further details, turn on tracing and reexecute the operation. Turn off tracing when the operation is complete.
UPDATE:
Problem could be caused by overflow of Windows event journal. Check Oracle's events here:
Start menu => Control Panel => Administrative Tools => Event Viewer
You should either clear journal manually or increase its' size
