(JdbcDBProvider
ReplNext
ERROR 2008/02/26
16:34:18.544 (CST)) Failed
processing <SQL not available>
SQL State: 08S01
Error Code: 0
Message:
Cannot connect to
MySQL server on
10.10.90.57:5010.
Is there a
MySQL server running on the
machine/port you are trying to
connect to?
(java.net.ConnectException)
Port 5010 isn’t
LISTENING
Review the error message
to determine which server
generated the error. In the
error to the left, the server
cannot connect to its
ReplNext peer.
Go to the ReplNext peer
and verify:
1
The SafeWord
Database service is
started.
2
Port 5010 is in the
LISTENING state using
‘netstat –na | more’
command.
A firewall is
blocking
connections
over port
5010.
•
Open a command
window (on ReplNext)
and perform a telnet
test to localhost over
port 5010 (
telnet
localhost 5010
) to
verify port 5010 is
accepting connections,
‘telnet localhost 5010’.
•
If local connectivity
works but the remote
MySQL server cannot
connect, investigate
the possibility that a 3
rd
party device is blocking
the connection.
