Sridhar Jena created DERBY-6972:
-----------------------------------
Summary: Delay for getting derby connection (Connection Reset and
Waiting for a connection)
Key: DERBY-6972
URL: https://issues.apache.org/jira/browse/DERBY-6972
Project: Derby
Issue Type: Bug
Components: Network Server
Affects Versions: 10.11.1.1
Reporter: Sridhar Jena
Priority: Critical
Hi Team,
This is regarding a derby connection issue in network mode.
We are using Apache derby in network mode. Below are the version we are using
for client server communication,
Client Jar Version : *derbyclient-10.13.1.1.jar*
Server Version : * Apache Derby Network Server - 10.11.1.1*
We are facing three types of connection issue while getting database connection
from our java application.
1. A communications error has been detected: Connection reset
2. Waiting for a connection with a long period of time.
3. Error connecting to server 127.0.0.1 on port 1,527 with message connect
timed out.
At the same time if we are checking the derby.log in derby server, we found
below exceptions,
*Fri Oct 20 17:19:30 EDT 2017* Thread[DRDAConnThread_107,5,main] (DATABASE =
null), (DRDAID = null), Execution failed because of a Distributed Protocol
Error: DRDA_Proto_SYNTAXRM; CODPNT arg = 0; Error Code Value = 3. Plaintext
connection attempt from an SSL enabled client?
*Fri Oct 20 17:19:30 EDT 2017* : Execution failed because of a Distributed
Protocol Error: DRDA_Proto_SYNTAXRM; CODPNT arg = 0; Error Code Value = 3.
Plaintext connection attempt from an SSL enabled client?
org.apache.derby.impl.drda.DRDAProtocolException: Execution failed because of a
Distributed Protocol Error: DRDA_Proto_SYNTAXRM; CODPNT arg = 0; Error Code
Value = 3. Plaintext connection attempt from an SSL enabled client?

We have no idea about the above Exceptions why it is coming while getting
connection in java client application.
Could you please help us to identify the exact reason for the above problem.
Thanks & Regards,
Sridhar Jena
