Hi,
Is there any specific advantage of using WebSphere Adapter for JDBC instead of using the built-in nodes in WMB for database interaction ? Does the JDBC adapter perform better as compared to the nodes (in WMB 7 and above) particularly when the number of database transaction is huge ?
Any insight on this would be appreciated.
Thanks. |

well, if we're talking about high volume, I have a tendency of pushing DB connectivity off the broker into a J2EE environment reading from a queue with and MDB. Advantage: the DB and the broker flow now scale independently.
Have fun

| The DatabaseInput node *is* the WebSphere Adapter. |

No it's not! The DBInput node uses ESQL to access the DB and is ODBC only...
Kind regards,

An important reason why you would use a (standalone - one without Message Broker) Adapter is that you need to retrieve data remotely (remote to a/the Broker): You want a reliable QMGR to QMGR connection (through the network (distance)). So 2 QMGRs: One with Broker (e.g. centrally in your companies head office) and one (or some/many) with just (we used the WBI-Adapter-Framework) an "Adapter" (without a Msg-Broker) (e.g. decentrally in your companies subsideries... e.g. distributed worldwide).
So: (probably) you cannot install a broker everywhere... so you "just" install e.g. the WBI-adapters framework. Which adapter do you use?
Though afaikr there is the possibility to deploy/install msg-broker "like an adapter" / a reduced version "in adapter mode" since version 7(?).
I'd always prefer to use broker to access a DB (over (installing and configuring) the WBI-Adapter-Framework). But for reliability reason the DB you are accessing should/must be near... probably don't access a (remote) DB, where your JDBC or ODBC has to go through some network hops.
