How does Integration Server identify an adapter Connection as in-active connection ?
Like

You can try using an built in service to check the status of a connection pub.art.connection:queryConnectionState

you can check connection status by using built in services WmArt;pub;art;connection folder;get connection statastics

Integration server calls the adapter related methods in listResources.dsp page by specifying arguments like adapterTypeName=JDBCAdapter, connectionAliasName=xxxxxxxxxxx........... in this case IS calls the builtin service as mentioned by wash@idn...... and based on the reply from that service(output) IntegrationServer checks whether the adapter Connection as inactive or active connection.................

Sounds Good Piapavola, thanks! But, is this a scheduler job that IS performs at regular intervals or what could be the timing..
