Hmmm - ADMA5107E and CWWBA0008E seen whilst uninstalling a SCA module from IBM BPM Advanced 8.5.7

Hmmm, I started seeing this whilst attempting to remove an existing SCA module ( EAR file ) from a BPM Advanced 8.5.7 environment: -

Caused by: com.ibm.bpe.api.ProcessTemplateNotFoundException: CWWBA0008E: Process template 'processMessage. Tue 2017-05-16 18:11:58.000' is not found.

There wasn't a corresponding Process Template showing up in the BPC Explorer: -

https://bpm857.uk.ibm.com:8443/bpc/faces/pages/Default.jsp?BPCTZ=-60

even whilst logged in as the Deployment Environment super-user, deAdmin.

I'd tried the obvious - stopping the entire DE - Cluster Members, Node Agent, Deployment Manager etc. - but to no avail.

I even tried removing the wstemp directory from within the DM's profile, but again no dice.

Working on the assumption that the problem was in the WAS rather than BPM world ( because BPC Explorer showed no template ), I took the nuclear option of removing the JEE application from the DM configuration: -

cd /opt/ibm/WebSphereProfiles/Dmgr01/config/cells/PSCell1/applications
rm -Rf MQ_Test.ear/

restarted the Deployment Manager, and forcibly resynced the node: -

/opt/ibm/WebSphereProfiles/Dmgr01/bin/wsadmin.sh -lang jython -user wasadmin -password passw0rd

AdminControl.invoke('WebSphere:name=repository,process=nodeagent,platform=common,node=Node1,version=5.0,type=ConfigRepository,mbeanIdentifier=repository,cell=PSCell1,spec=1.0', 'refreshRepositoryEpoch')
AdminControl.invoke('WebSphere:name=cellSync,process=dmgr,platform=common,node=Dmgr,version=8.5.5.11,type=CellSync,mbeanIdentifier=cellSync,cell=PSCell1,spec=1.0', 'syncNode', '[Node1]')

Having done the latter, the app disappeared from the All Applications view: -

and, more importantly, I was then able to install a fresh copy of the SCA module: -

AdminApp.install('/tmp/'+AppName+'.ear', '[ -nopreCompileJSPs -distributeApp -nouseMetaDataFromBinary -nodeployejb -appname '+AppName+' -createMBeansForResources -noreloadEnabled -nodeployws -validateinstall warn -processEmbeddedConfig -filepermission .*\.dll=755#.*\.so=755#.*\.a=755#.*\.sl=755 -noallowDispatchRemoteInclude -noallowServiceRemoteInclude -asyncRequestDispatchType DISABLED -nouseAutoLink -noenableClientModule -clientMode isolated -novalidateSchema -MapResRefToEJB [[ '+AppName+'Web "" '+AppName+'Web.war,WEB-INF/web.xml sca/resource/export/readTheMessage_MQEXPORT_CF javax.jms.ConnectionFactory jms/'+conFact+' "" "" "" ] -MapModulesToServers [[ MQ_TestWeb MQ_TestWeb.war,WEB-INF/web.xml WebSphere:cell='+cellID+',cluster='+clusterName+' ]]]')
AdminConfig.save()
AdminNodeManagement.syncActiveNodes()

and start the application: -

AdminControl.invoke('WebSphere:name=ApplicationManager,process=AppClusterMember1,platform=proxy,node=Node1,version=8.5.5.11,type=ApplicationManager,mbeanIdentifier=ApplicationManager,cell=PSCell1,spec=1.0', 'startApplication', '[MQ_Test]')

which is always nice :-)
