IBM Operational Decision Manager Rules - Problems augmenting profiles

So I've been battling with an issue today, whilst also wrestling with SSL/TLS ciphers and wrangling and munging Java class loader issues.

Essentially, I've installed IBM Operational Decision Manager (ODM) Advanced Decision Server onto my Linux VM.

I'm then creating the necessary WebSphere Application Server (WAS) profiles to build out an ODM cell.

Here's the profile creation part: -

/opt/ibm/WebSphere/AppServer/bin/manageprofiles.sh -create -templatePath /opt/ibm/WebSphere/AppServer/profileTemplates/management -profileName Dmgr01 -nodeName Dmgr -isDefault -enableAdminSecurity true -adminUserName wasadmin -adminPassword passw0rd

/opt/ibm/WebSphere/AppServer/bin/manageprofiles.sh -create -templatePath /opt/ibm/WebSphere/AppServer/profileTemplates/managed -profileName AppSrv01 -nodeName Node1


I then start the Deployment Manager: -

/opt/ibm/WebSphere/AppServer/profiles/Dmgr01/bin/startManager.sh

and add the node into the cell: -

/opt/ibm/WebSphere/AppServer/profiles/AppSrv01/bin/addNode.sh `hostname` 8879 -profileName AppSrv01 -username wasadmin -password passw0rd

Finally ( for now ) I stop the Deployment Manager: -

/opt/ibm/WebSphere/AppServer/profiles/Dmgr01/bin/stopManager.sh -username wasadmin -password passw0rd

before augmenting the DM profile: -

/opt/ibm/WebSphere/AppServer/bin/manageprofiles.sh -augment -profileName Dmgr01 -templatePath /opt/ibm/WebSphere/AppServer/profileTemplates/rules/management/ds/

This bit failed with: -

To the best of my knowledge / experience, that should've been all I needed ( from a pure ODM perspective ).

And yet .....

I dug back into a prior blog post: -


which is what had led me to install this particular component of ODM: -

So that's all good then .....

I do need to work out the differences but that's a job for another day ...

IBM Business Process Manager - What Goes In What Databases ?

My client asked me this, so I thought I'd share it here.

Context

In the world of IBM BPM Advanced 8.5, with DB2, we have three (five) distinct databases.

Most typically, we have the Process Server database ( often known as the BPM Database, BPMDB ), the Shared Database ( often known as the Common Database, CMNDB ) and the Performance Database ( often known as the Performance Data Warehouse Database, PDWDB ).

Optionally, we can have two more databases; the Messaging Engine Database ( MEDB ) and the Business Process Choreographer Database ( BPCDB ).




Most of the time, I use the three DB topology pattern, which is more-or-less the default. This separation allows me to put different databases in different places, perhaps on different disks ( LUNs ), user IDs ( instances ), different servers etc.

For the record, I'm a DB2 guy by trade, so I realise that, in the world of Oracle, we have a single database ( Oracle itself ) and multiple schemas.

But the principle remains much the same ...

New iCloud Terms and Conditions

I kept seeing this on an iPhone 5S after an update to iOS 9.1: -


New iCloud Terms and Conditions

To use iCloud on this iPhone you must accept the new Terms and Conditions.

However, each time I clicked on View Terms I merely got taken to the iCloud page in Settings, which made no difference.

I tried Turning It Off And On Again but to no avail.

I then Google'd about for a while, and found a post suggesting that I needed to go into Settings > Mail, Contacts, Calendars.

I then selected the iCloud mail account and ... saw a Terms and Conditions link.

I selected this, read the Ts & Cs, accepted them and .... we're now good to go :-)

Which is nice :-)

Hmmm, Process Portal Not Playing Nicely - IBM BPM Advanced 8.5.5.0

Problem

Hitting Process Portal, either via IHS ( on port 8443 ) or directly ( on port 9443 / 9446 ) results in a garbled page, with most of the artefacts down the left-hand side of the page.

Feels like client-server issue, perhaps problem at IP stack

Definitely red herring - known "problem" covered in multiple Technotes

A XJMS0021E error occurs in the SystemOut.log file for IBM Business Process Manager (BPM) Version 8.5

XJMS0021E destination and bus workclass problem is logged to WAS systemOUT

Further Analysis

Used Firefox Debugger ( [Fn] [F12] )

Solution

Force BusinessSpace to reload BusinessSpace - templates, spaces and themes

Edit: -

/opt/ibm/WebSphereProfiles/PSCell1AppSrv01/BusinessSpace/AppCluster/mm.runtime.prof/public/oobLoadedStatus.properties

and change from: -

#Mon Oct 19 14:08:27 BST 2015
importTemplates.txt=false
importSpaces.txt=false
importThemes.txt=false


to: -

#Mon Oct 19 14:08:27 BST 2015
importTemplates.txt=true
importSpaces.txt=true
importThemes.txt=true


and restart AppCluster

( File is then reset back to false setting once cluster has been restarted - once templates, spaces etc. have been reset to their OOB defaults )

Problem does *NOT* appear to recur, including java.io.IOException exception

IBM HTTP Server - Working with Default Certificates issued by a Certificate Authority

I'm working through a process to have IBM HTTP Server (IHS) and WebSphere Application Server (WAS) use certificates minted by a Certificate Authority, specifically Microsoft Windows Server 2008, rather than using so-called self-signed certificates.

In the past, the bulk of my experience has been using self-signed certificates in IHS, although I did do some work with a client ~4-5 years ago where we were using CA-signed certificates.

Equally, I've only ever had WAS act as a certificate signer, which has been the default for ages. In this regard, WAS is the signer, and takes care of issuing and replacing certificates throughout the cell.

However, on my current project, we have a requirement to use CA-signed certificates throughout the estate.

Therefore, whilst I've made some great progress with WAS using Windows CA-signed certificates ( about which I'll blog later ), I did hit a roadblock with IHS.

I started by creating a Certificate Signer Request (CSR) as follows: -

/opt/ibm/HTTPServer/bin/gskcapicmd -certreq -create -db /opt/ibm/HTTPServer/ssl/keystore.kdb -pw passw0rd -label wasdemo.uk.ibm.com -dn cn=wasdemo.uk.ibm.com -file /home/wasadmin/wasdemo.uk.ibm.com.arm -size 2048 -sigalg SHA256WithRSA

and sent the resulting wasdemo.uk.ibm.com.arm file to my Windows Server box.

Once I'd created the certificate, I got back a file from the CA in the PKCS7 format - certnew.p7b.

Initially I imported this file into IHS' key store, I was able to list it: -

/opt/ibm/HTTPServer/bin/gskcapicmd -cert -list -db /opt/ibm/HTTPServer/ssl/keystore.kdb -pw passw0rd

Certificates found
* default, - personal, ! trusted, # secret key
- wasdemo.uk.ibm.com


which was fine.

I then set the certificate to be the default: -

/opt/ibm/HTTPServer/bin/gskcapicmd -cert -setdefault -label wasdemo.uk.ibm.com -db /opt/ibm/HTTPServer/ssl/keystore.kdb -pw passw0rd

However, when I attempted to validate that the certificate was default, I still saw this: -

/opt/ibm/HTTPServer/bin/gskcapicmd -cert -list -db /opt/ibm/HTTPServer/ssl/keystore.kdb -pw passw0rd

Certificates found
* default, - personal, ! trusted, # secret key
- wasdemo.uk.ibm.com


and, worse still, this was what I saw when I queried the default certificate within the key store: -

/opt/ibm/HTTPServer/bin/gskcapicmd -cert -getdefault -db /opt/ibm/HTTPServer/ssl/keystore.kdb -pw passw0rd

CTGSK3029W The database does not contain a certificate with label "GSKCAPICMD_TXT_DEFAULT" 

-Command usage-
-db                   Required
-pw | -stashed        Optional
-type                 Optional <cms | kdb | pkcs12 | p12>

 
Long story short, it was a PEBCAK.

I was doing it wrong ....

This was what I should've done ....

Take it from the top ....

Create the Keystore

/opt/ibm/HTTPServer/bin/gskcapicmd -keydb -create -db /opt/ibm/HTTPServer/ssl/keystore.kdb -pw passw0rd -type cms -expire 3650 -stash

Create the CSR

/opt/ibm/HTTPServer/bin/gskcapicmd -certreq -create -db /opt/ibm/HTTPServer/ssl/keystore.kdb -pw passw0rd -label wasdemo.uk.ibm.com -dn cn=wasdemo.uk.ibm.com -file /home/wasadmin/wasdemo.uk.ibm.com.arm -size 2048 -sigalg SHA256WithRSA

List the Certificates - of which there should be none

/opt/ibm/HTTPServer/bin/gskcapicmd -cert -list -db /opt/ibm/HTTPServer/ssl/keystore.kdb -pw passw0rd

No certificates were found.

Add the root certificate ( obtained from the Windows box )

/opt/ibm/HTTPServer/bin/gskcapicmd -cert -add -file certnew.cer -db /opt/ibm/HTTPServer/ssl/keystore.kdb -pw passw0rd

List the Certificates - should now show the root certificate

/opt/ibm/HTTPServer/bin/gskcapicmd -cert -list -db /opt/ibm/HTTPServer/ssl/keystore.kdb -pw passw0rd

Certificates found
* default, - personal, ! trusted, # secret key
! CN=uk-WIN-AJ9S32NP29C-CA,DC=uk,DC=ibm,DC=com

Note the symbol ( ! ) to show that the root certificate is trusted

Receive the Personal Certificate for IHS

/opt/ibm/HTTPServer/bin/gskcapicmd -cert -receive -file certnew.p7b -db /opt/ibm/HTTPServer/ssl/keystore.kdb -pw passw0rd

List the Certificates - should now show both certificates

/opt/ibm/HTTPServer/bin/gskcapicmd -cert -list -db /opt/ibm/HTTPServer/ssl/keystore.kdb -pw passw0rd

Certificates found
* default, - personal, ! trusted, # secret key
! CN=uk-WIN-AJ9S32NP29C-CA,DC=uk,DC=ibm,DC=com
- wasdemo.uk.ibm.com


Note the symbol ( - ) to show that the certificate is personal
Also note that the the personal certificate is NOT shown as default - it has no asterisk ( * ) symbol next to it

Now when I start IHS and access it via Internet Explorer from the Windows server itself: -



it all works and, more importantly, the browser trusts IHS and doesn't show any exceptions re untrusted certificates.

Which is nice ...

Fascinating - Internet Explorer and the Lack of Transport Layer Security

I've just spent a happy 10 minutes trying to work out why Internet Explorer 8 wouldn't load a secure web page from WebSphere Application Server, specifically the Integrated Solutions Console (ISC).

This is what I saw from IE: -


whereas Firefox was more than happy to render the page: -


Then I thought back to something a colleague had said earlier in the week ....

I'm using TLS 1.2 as my default encryption in WAS ( see an earlier blog post - WebSphere Application Server - Tinkering with Property Files and a spot of SSL/TLS ) and, therefore, WAS is expecting any client, including a browser, to support TLS 1.2.

Firefox confirms the encryption : -


Thinking back to what my colleague had said, I checked IE's settings: -


and, guess what ....


For the record, I am experimenting with the replacement of WAS' own CA-managed certificates ( yes, WAS can/does act as a Certificate Authority for certificates used inside the cell ) with those generated by Active Directory.

I'll write this up more fully in the future, but one of the net effects is that Internet Explorer, running in the same AD domain, now trusts the WAS HTTPS-secured pages, because they share the same CA signer.

Which is nice ....

*UPDATE*

For the record, WAS was trying to tell me what was going wrong, with: -

...
[15/10/15 15:22:39:130 BST] 000000d4 SSLHandshakeE E   SSLC0008E: Unable to initialize SSL connection.  Unauthorized access was denied or security settings have expired.  Exception is javax.net.ssl.SSLHandshakeException: Client requested protocol TLSv1 not enabled or not supported

if only I'd looked in SystemOut.log :-)

WebSphere Application Server - Tinkering with Property Files and a spot of SSL/TLS

This is in the context of my ongoing voyage of discovery with Transport Layer Security (TLS) 1.2 within a WebSphere Application Server (WAS) 8.5.5.7 cell.

It is, for this reason, that I was reading this: -


Specifically, having enabled TLS 1.2 as the default protocol for my cell: -

/opt/ibm/WebSphere/AppServer/profiles/Dmgr01/bin/wsadmin.sh -lang jython -user wasadmin -password passw0rd

cellID=AdminControl.getCell()

AdminTask.modifySSLConfig('[-alias CellDefaultSSLSettings -scopeName (cell):'+cellID+' -keyStoreName CellDefaultKeyStore -keyStoreScopeName (cell):'+cellID+' -trustStoreName CellDefaultTrustStore -trustStoreScopeName (cell):'+cellID+' -jsseProvider IBMJSSE2 -sslProtocol TLSv1.2 -clientAuthentication false -clientAuthenticationSupported false -securityLevel HIGH -enabledCiphers ]')

As soon as I save and synchronise the changes: -

AdminConfig.save()
AdminNodeManagement.syncActiveNodes()


I see this exception: -

ADMS0206I: The configuration synchronization failed for node: AppSrv01Node.

in the Deployment Manager's SystemOut.log file, and this: -

[08/10/15 15:19:45:430 BST]     FFDC Exception:javax.net.ssl.SSLHandshakeException SourceId:com.ibm.ws.management.filetransfer.client.FileTransferClientImpl.download ProbeId:1575 Reporter:com.ibm.ws.management.filetransfer.client.FileTransferClientImpl@a36b36a1
javax.net.ssl.SSLHandshakeException: Remote host closed connection during handshake

...

Caused by: java.io.EOFException: SSL peer shut down incorrectly

in the Node Agent's FFDC log.

"Talking" this through with the wider WebSphere team, it was pointed out that, by default, I have Dynamic SSL Configuration enabled: -

which means that, as soon as I committed the change, the Deployment Manager immediately starting using AND enforcing TLS 1.2, whereas the Node Agent(s) continued using SSL/TLS.

I could see this by comparing/contrasting the cell and node-level security.xml files: -

diff AppSrv01/config/cells/WASCell/security.xml Dmgr01/config/cells/WASCell/security.xml

108c108
<     <setting xmi:id="SecureSocketLayer_1" clientAuthentication="false" securityLevel="HIGH" enabledCiphers="" jsseProvider="IBMJSSE2" sslProtocol="SSL_TLS" keyStore="KeyStore_1" trustStore="KeyStore_2" trustManager="TrustManager_2" keyManager="KeyManager_1"/>
---
>     <setting xmi:id="SecureSocketLayer_1" clientAuthentication="false" securityLevel="HIGH" enabledCiphers="" jsseProvider="IBMJSSE2" sslProtocol="TLSv1.2" keyStore="KeyStore_1" trustStore="KeyStore_2" trustManager="TrustManager_2" keyManager="KeyManager_1"/>

where the first is from the node and the second is from the DM.

Bill's presentation ( see the earlier link ) explicitly warns about this, on page 56: -

WARNING: BE SURE TO DISABLE dynamic SSL Prior to turning on strict mode. The Dmgr and Nodes will be in a incompatible mode. The Dmgr will likely switch to TLSv1.2 before the nodes do, they will likely still be at SSL_TLS, and the nodes and dmgr will no long be able to communicate. We STRONGLY RECOMMEND that you stop all the nodes except the Dmgr. Do the conversion on the console, restart the Dmgr, manually sync the nodes, then start the node agents and servers.

To start with, I experimented by disabling Dynamic SSL Configuration.

Whilst I knew that I could manually modify security.xml I was looking for a programmatic / scripted way of achieving this.

This is what I did: -

configProperties=AdminConfig.list('Cell')
AdminTask.extractConfigProperties(configProperties, '[-propertiesFileName /tmp/davehay.properties -filterMechanism SELECTED_SUBTYPES -selectedSubTypes [Security ] ]')


The resulting file - /tmp/davehay.properties - includes the line: -

dynamicallyUpdateSSLConfig=true #boolean,default(false)

Therefore, I created a pair of property files: -

dynamic_off.properties

# SubSection 1.0 # Security Section
#
ResourceType=Security
ImplementingResourceType=Security
ResourceId=Cell=!{cellName}:Security=ID#Security_1
#

#
#Properties
#
dynamicallyUpdateSSLConfig=false #boolean,default(false)


dynamic_on.properties

# SubSection 1.0 # Security Section
#
ResourceType=Security
ImplementingResourceType=Security
ResourceId=Cell=!{cellName}:Security=ID#Security_1
#

#
#Properties
#
dynamicallyUpdateSSLConfig=true #boolean,default(false)


which allowed me to turn off Dynamic Security Configuration: _

AdminTask.validateConfigProperties('-propertiesFileName /tmp/dynamic_off.properties')
AdminConfig.save()
AdminNodeManagement.syncActiveNodes()

which returns 'true'

and then turn it back on again: -

AdminTask.validateConfigProperties('-propertiesFileName /tmp/dynamic_off.properties')
AdminConfig.save()
AdminNodeManagement.syncActiveNodes()


which again returns 'true' :-)

However, I realised that I was going against the recommendation from Bill i.e. to ONLY have the Deployment Manager running, make the SSL_TLS > TLSv1.2 change and then manually synchronise the node(s).

This is what I did, in summary: -

------------------------------------------------------------------------------------

(a) Fully syncronise the cell

(b) Stop the Node Agent

(c) Modify the SSL configuration: -

AdminTask.modifySSLConfig('[-alias CellDefaultSSLSettings -scopeName (cell):WASCell -keyStoreName CellDefaultKeyStore -keyStoreScopeName (cell):WASCell -trustStoreName CellDefaultTrustStore -trustStoreScopeName (cell):WASCell -jsseProvider IBMJSSE2 -sslProtocol TLSv1.2 -clientAuthentication false -clientAuthenticationSupported false -securityLevel HIGH -enabledCiphers ]')

(d) Update the Node's ssl.client.props file to reflect the fact that we're now using TLS v1.2 rather than SSL_TLS

vi /opt/ibm/WebSphere/AppServer/profiles/AppSrv01/properties/ssl.client.props

changing from: -

com.ibm.ssl.protocol=SSL_TLS

to: -

com.ibm.ssl.protocol=TLSv1.2

(e) Synchronise the Node with the cell: -

 /opt/ibm/WebSphere/AppServer/profiles/AppSrv01/bin/syncNode.sh `hostname` -user wasadmin -password passw0rd

(f) Validate that DM and Node have consistent SSL/TLS settings: -

diff /opt/ibm/WebSphere/AppServer/profiles/Dmgr01/config/cells/WASCell/security.xml /opt/ibm/WebSphere/AppServer/profiles/AppSrv01/config/cells/WASCell/security.xml

(g) Start the node

(h) Validate that I can see the node from the DM

(i) Mix a Margherita     

------------------------------------------------------------------------------------

So, what did I learn ?

Firstly, read Bill's document from cover to cover.
Secondly, remember Dynamic SSL Configuration.
Thirdly, I now know how to work with WAS property files in Jython
Fourthly, I like Margheritas

WebSphere Application Server and Liberty Security Update

This is what I'm reading right now, in the context of enabling Transport Layer Security (TLS) 1.2 within a WebSphere Application Server Network Deployment 8.5.5.7 infrastructure: -

WebSphere Application Server and Liberty Security Update [PDF]

which was authored and presented at Impact in 2013 by Bill O'Donnell, STSM – WebSphere Foundation Security Architect IBM – WebSphere Development.

Bill also actively manages this important site: -

WebSphere Application Server security

Maintain and strengthen the security of your WebSphere Application Server environment

which is definitely worth book-marking.

MQ - AMQ9637: Channel is lacking a certificate

I wrote this post a wee while back, and those nice developerWorks folks have kindly published it for me: -


...
In the context of configuring encrypted connections between WebSphere / IBM MQ and WebSphere Application Server, I'm currently building a scripted process to set up the infrastructure end-to-end, which I'm testing on a VM. For the record, I'm using IBM MQ 8.0.0.2 and WebSphere Application Server (WAS) 8.5.5.2.
...
At this point, I hit an issue. Instead of a happy message, I saw:

javax.net.ssl.SSLHandshakeException: javax.net.ssl.SSLHandshakeException: Remote host closed connection during handshake

More importantly, this is what I saw in the Queue Manager's log:

----- amqrmrsa.c : 930 --------------------------------------------------------
10/09/15 08:14:35 - Process(25255.10) User(mqm) Program(amqrmppa)
                    Host(bpm856.uk.ibm.com) Installation(Installation1)
                    VRMF(8.0.0.2) QMgr(TESTQM)
                   
AMQ9637: Channel is lacking a certificate.

EXPLANATION:
The channel is lacking a certificate to use for the SSL handshake. The channel
name is '????' (if '????' it is unknown at this stage in the SSL processing).

The remote host is '????'.

The channel did not start.
ACTION:
Make sure the appropriate certificates are correctly configured in the key
repositories for both ends of the channel.

...

Want to know what happened ?

Caused by: java.lang.ClassNotFoundException: com.ibm.db2.jcc.DB2XADataSource

This came about because I was using a JDBC Provider and Data Source, both of which I'd created at the scope of the cell: -

Create JDBC Provider

cellID=AdminControl.getCell()

provider=AdminTask.createJDBCProvider('[-scope Cell='+cellID+' -databaseType DB2 -providerType "DB2 Using IBM JCC Driver" -implementationType "XA data source" -name "DB2 Using IBM JCC Driver (XA)" -description "Two-phase commit DB2 JCC provider that supports JDBC 4.0 using the IBM Data Server Driver for JDBC and SQLJ. IBM Data Server Driver is the next generation of the DB2 Universal JCC driver. Data sources created under this provider support the use of XA to perform 2-phase commit processing. Use of JDBC driver type 2 on WebSphere Application Server for Z/OS is not supported for data sources created under this provider. This provider is configurable in version 7.0 and later nodes." -classpath [${DB2_JCC_DRIVER_PATH}/db2jcc4.jar ${DB2_JCC_DRIVER_PATH}/db2jcc_license_cu.jar ] -nativePath [${DB2_JCC_DRIVER_PATH} ] ]')


Create JDBC Data Source

AdminTask.createDatasource(provider, '[-name Sample -jndiName jdbc/Sample -dataStoreHelperClassName com.ibm.websphere.rsadapter.DB2UniversalDataStoreHelper -containerManagedPersistence true -componentManagedAuthenticationAlias db2user1 -xaRecoveryAuthAlias -configureResourceProperties [[databaseName java.lang.String SAMPLE] [driverType java.lang.Integer 4] [serverName java.lang.String wasdemo.uk.ibm.com] [portNumber java.lang.Integer 60006]]]')

Whilst I was able to happily test the datasource: -

AdminControl.invoke('WebSphere:name=DataSourceCfgHelper,process=dmgr,platform=dynamicproxy,node=Dmgr,version=8.5.5.5,type=DataSourceCfgHelper,mbeanIdentifier=DataSourceCfgHelper,cell=WASCell,spec=1.0', 'testConnection', '[cells/WASCell|resources.xml#DataSource_1444136343751]', '[java.lang.String]')

my application failed with the above exceptions.

The solution ?

The application, running on the Application Server on the Node, is referencing a cell-scoped JDBC data source using a cell-scoped JDBC provider .... which has a WebSphere Variable - DB2_JCC_DRIVER_PATH - which is only available at the cell-level.

However, that wasn't the problem :-)

When I dug further, I *DID* have an identically named variable, scoped at the node-level: -


Can you see what I did wrong ?

Yes, I had a variable scoped at the node, which trumps the cell, which had a null value.

Once I fixed this: -

AdminConfig.modify('(cells/WASCell/nodes/AppSrv01Node|variables.xml#VariableSubstitutionEntry_1444248288880)', '[[symbolicName "DB2_JCC_DRIVER_PATH"] [description ""] [value "/opt/ibm/WebSphere/AppServer/jdbcdrivers/DB2/ "]]')

everything was lovely again :-)

This was definitely of use: -

as did this: -

Doh, WebSphere Application Server to DB2 via JDBC - Get the schema right, fool

I'm writing a tutorial for my team, taking them through the process of building a WebSphere Application Server (WAS) configuration, with IBM HTTP Server (IHS) and DB2.

For the WAS > DB2 piece, I've written the necessary Jython scripts to create a JDBC provider and data source, and deploy a sample Java EE web application.

However, during testing, I hit an interesting issue, evidenced by this exception: -

[07/10/15 19:41:21:224 BST] 0000008e SystemErr     R com.ibm.db2.jcc.am.SqlSyntaxErrorException: DB2 SQL Error: SQLCODE=-204, SQLSTATE=42704, SQLERRMC=DB2USER1.EMPLOYEE, DRIVER=4.19.26

in SystemErr.log.

Long story short, I'm connecting from WAS to DB2 using the user ID db2user1 which has DBADM permissions to the database, the SAMPLE database that one creates using the command db2sampl.

However, when I ran the initial db2sampl command, I took the path of least resistance, aka the default :-)

Therefore, I'd created the data ( tables etc. ) in the wrong schema - db2inst1 - whereas WAS is expecting to use the schema db2user1

To prove this, I checked DB2: -

db2 connect to sample

   Database Connection Information

 Database server        = DB2/LINUXX8664 10.5.5
 SQL authorization ID   = DB2INST1
 Local database alias   = SAMPLE


db2 "select * from db2user1.employee"

SQL0204N  "DB2USER11.EMPLOYEE" is an undefined name.  SQLSTATE=42704

There are a number of solutions to this problem, I chose to drop and then recreate the SAMPLE database: -

drop database sample

db2sampl -schema db2user1

Now my query works: -

db2 "select * from db2user1.employee"

  42 record(s) selected.

I then saw: -

[07/10/15 20:11:05:359 BST] 0000009f SystemErr     R com.ibm.db2.jcc.am.SqlSyntaxErrorException: DB2 SQL Error: SQLCODE=-551, SQLSTATE=42501, SQLERRMC=DB2USER1;SELECT;DB2USER1.EMPLOYEE, DRIVER=4.19.26

which I again validated in DB2 as follows: -

db2 connect to sample user db2user1 using passw0rd

   Database Connection Information

 Database server        = DB2/LINUXX8664 10.5.5
 SQL authorization ID   = DB2USER1
 Local database alias   = SAMPLE


db2 "select * from db2user1.employee"

SQL0551N  The statement failed because the authorization ID does not have the 
required authorization or privilege to perform the operation.  Authorization 
ID: "DB2USER1".  Operation: "SELECT". Object: "DB2USER1.EMPLOYEE".  
SQLSTATE=42501


Of course, I'd rebuilt the DB but forgot to grant db2user1 access to it :-)

This was easily fixed: -

db2 connect to sample user db2inst1 using passw0rd
db2 grant dbadm on database to user db2user1

db2 terminate

and re-tested: -

db2 connect to sample user db2user1 using passw0rd
db2 "select * from db2user1.employee"

and, more importantly, my Java code now works :-)

Which is nice :-)
