Question

I am running BAM 2.4.1 in windows.

set in carbon.xml.

<Ports>

        <!-- Ports offset. This entry will set the value of the ports defined below to
         the define value + Offset.
         e.g. Offset=2 and HTTPS port=9443 will set the effective HTTPS port to 9445
         -->
        <Offset>200</Offset>

But after press "Cassandra Keyspaces" in "Main" of management console I get errors in console

The following error details are available. Please refer logs for more details.

and error in server log

[2014-07-24 18:09:43,190]  WARN {me.prettyprint.cassandra.connection.CassandraHo

n: Unable to open transport to localhost(127.0.0.1):9160 , java.net.ConnectExcep
tion: Connection refused: connect

note, what port 9160 is not correct.

https://wso2.org/jira/browse/BAM-1476 reported as Fixed [ 1 ] but....

What is wrong?

Answer 1

Change 9160 value in the WSO2BAM_CASSANDRA_DATASOURCE section to 9160+portOffset. Also change /conf/etc/hector-config.xml with the same value.
