Oracle Service Names - I *WILL* get this right - EVENTUALLY

I saw this: -

Bootstraping data into cluster AppCluster and logging into /opt/ibm/WebSphereProfiles/Dmgr01/logs/bootstrapProcesServerData.AppCluster.log

WASX7357I: By request, this scripting client is not connected to any server process. Certain configuration and application operations will be available in local mode.
java.sql.SQLRecoverableException: Listener refused the connection with the following error:
ORA-12514, TNS:listener does not currently know of service requested in connect descriptor
...

Caused by: oracle.net.ns.NetException: Listener refused the connection with the following error:
ORA-12514, TNS:listener does not currently know of service requested in connect descriptor
...

 
whilst running the bootstrap process for an IBM BPM environment: -

/opt/ibm/WebSphereProfiles/Dmgr01/bin/bootstrapProcessServerData.sh -clusterName AppCluster

Again, this is because I keep getting confused between the Oracle SID and the service name.

This helped: -

Once I realised which was which, I updated my JDBC datasources to reflect the correct Service Name ( oracle.uk.ibm.com ) and all is now well: -

/opt/ibm/WebSphereProfiles/Dmgr01/bin/bootstrapProcessServerData.sh -clusterName AppCluster

Bootstraping data into cluster AppCluster and logging into /opt/ibm/WebSphereProfiles/Dmgr01/logs/bootstrapProcesServerData.AppCluster.log

WASX7357I: By request, this scripting client is not connected to any server process. Certain configuration and application operations will be available in local mode.
'BootstrapProcessServerData admin command completed successfully.....'

For the record, this WAS the URL that I had in my datasource: -

jdbc:oracle:thin:@//bpm857.uk.ibm.com:1521/orcl

and this is what I now have: -

jdbc:oracle:thin:@//bpm857.uk.ibm.com:1521/orcl.uk.ibm.com
