Hi, We are replacing an old (5.9) remote ActiveMQ Classic broker with a remote Artemis broker and have a few questions.
1. The Artemis broker is configured to persist messages in a database. Does e.g. <journal-type> and <paging-directory> have any effect at all when using a database? Which configurations are not relevant (ignored) when using a database? 2. We have a lot of old client applications which used to connect to the old Classic broker by using an antique resource adapter (5.9). We are trying to avoid changing anything in the client applications by simply redirecting the old host to the new Artemis broker (which has an OpenWire acceptor). At some of the time everything seems to work as expected (messages are delivered and consumed) but we are also seeing a lot of connectivity issues, e.g: ERROR [org.apache.activemq.artemis.core.server] AMQ224088: Timeout (10 seconds) on acceptor "artemis" during protocol handshake with /XXX:XXX:XXX.XXX:XXXXX has occurred. ERROR [org.apache.activemq.artemis.core.server] AMQ224126: Failure during protocol handshake on connection to /XXX:XXX:XXX.XXX:XXXXX from /XXX:XXX:XXX.XXX:XXXXX ERROR [org.apache.activemq.artemis.core.server] AMQ224014: Failed to close session WARN [org.apache.activemq.artemis.core.client] AMQ212037: Connection failure to /XXX:XXX:XXX.XXX:XXXXX has been detected: AMQ229014: Did not receive data from /XXX:XXX:XXX.XXX:XXXXX within the 30000ms connection TTL. The connection will now be closed. [code=CONNECTION_TIMEDOUT] WARN [org.apache.activemq.artemis.core.server] AMQ222103: transaction with xid XidImpl XXX timed out Any ideas on how to troubleshoot this? Any particular areas where we should pay particular attention? Could the problems depend on the old resource adapters? Could a bad database connection cause the problems? Any suggestions are welcome. Thanks in advance Calle
