IBM BPM and Oracle - Bootstrap challenges

So, whilst running the bootstrap command: -

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

I saw this: -

…
java.lang.Exception: java.lang.reflect.InvocationTargetException
…
Caused by: java.lang.reflect.InvocationTargetException
…
Caused by: java.lang.IllegalStateException: Failed to initialize registry
…
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'handlersMap': Cannot create inner bean 'com.lombardisoftware.server.ejb.persistence.PSDefaultHandler#f4e9076' of type [com.lombardisoftware.server.ejb.persistence.PSDefaultHandler] while setting bean property 'sourceMap' with key [TypedStringValue: value [Branch], target type [null]]; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'com.lombardisoftware.server.ejb.persistence.PSDefaultHandler#f4e9076' defined in class path resource [registry.persistence.xml]: Cannot resolve reference to bean 'dao.branch' while setting constructor argument; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dao.branch' defined in class path resource [registry.persistence.xml]: Instantiation of bean failed; nested exception is java.lang.ExceptionInInitializerError
…

etc.

So I checked the log: -

view /opt/ibm/WebSphereProfiles/Dmgr01/logs/bootstrapProcesServerData.AppCluster.log

and saw this: -

…

…

I checked that the Oracle 12c listener appeared to be running: -

netstat -aon|grep LISTEN

Notice the problem ?

Both the netstat and the lsnrctl commands show that the listener is "bound" to 127.0.0.1 rather than to the server's hostname.

The command completed successfully

I then saw this: -

ORA-12514, TNS:listener does not currently know of service requested in connect descriptor

which I solved via a previous blog post: -

So, the conclusion is that the Listener needs to know / care about the host name of the box: -

…
  (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=bpm.uk.ibm.com)(PORT=1521)))
…

whereas the BPM -> Oracle connectivity needs to know / care about the Oracle Service Name: -

sqlplus / as sysdba

SQL*Plus: Release 12.2.0.1.0 Production on Wed Jul 11 15:06:23 2018

Copyright (c) 1982, 2016, Oracle.  All rights reserved.


Connected to:
Oracle Database 12c Enterprise Edition Release 12.2.0.1.0 - 64bit Production

SQL> select value from v$parameter where name='service_names';

VALUE
--------------------------------------------------------------------------------
orcl.uk.ibm.com

SQL> exit

so the JDBC data sources need to look like this: -


This needs to be reflected in the BPM Deployment Environment properties file: -

…
bpm.de.db.1.databaseName=orcl.uk.ibm.com
…
bpm.de.db.2.databaseName=orcl.uk.ibm.com
…
bpm.de.db.3.databaseName=orcl.uk.ibm.com
…

So now we have this: -

/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

Note to self - use kubectl to query images in a pod or deployment

In both cases, we use JSON ... For a deployment, we can do this: - kubectl get deployment foobar --namespace snafu --output jsonpath="{...
