Executing external Python/Jython scripts from within WebSphere Application Server's wsadmin tool
Thu, Feb 27th 2014 30


TypeError: __add__ nor __radd__ defined for these operands

Whilst scripting the configuration of the WebSphere Application Server transaction/compensation/partner logs into an Oracle database: -

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

I saw this: -

WASX7209I: Connected to process "dmgr" on node Dmgr using SOAP connector;  The type of process is: DeploymentManager
WASX7017E: Exception received while running file "tranlogs.jy"; exception information: com.ibm.bsf.BSFException: exception from Jython:
Traceback (innermost last):
  File "<string>", line 18, in ?
TypeError: __add__ nor __radd__ defined for these operands


Last time I saw this error ( 2012 ), it was user error.

I checked my script ( specifically line 18 as per the exception ) : -

datasource=AdminTask.createDatasource(provider, '[-name '+clusterName+'_Tranlogs -jndiName jdbc/'+clusterName+'_Tranlogs -dataStoreHelperClassName com.ibm.websphere.rsadapter.Oracle11gDataStoreHelper -containerManagedPersistence true -componentManagedAuthenticationAlias '+j2cAlias+' -configureResourceProperties [[URL java.lang.String jdbc:oracle:thin:@//'+dbHost+':'+dbPort+'/'+dbName+']]]')

Looking at the concatenation of three strings ( dbHost, dbPort and dbName ) gave me a clue, and I checked the variables, and found: -

dbPort=1521

In other words, I'd defined it as an integer whereas Jython was expected a string.

Once I changed it: -

dbPort='1521'

the script ran without errors.

IBM DB2, Red Hat Enterprise Linux and the IBM Mainframe
Thu, Nov 16th 2017 5:54p   Dave Hay
I'm running through the process to deploy IBM Business Process Manager (BPM) 8.6 onto an IBM mainframe ….This is something that I've done a number of times before, since I first joined the (then) IBM Software Services for WebSphere team in late 2012.In essence, although the underlying hardware is the IBM z platform ( also known as LinuxOne in this guise ), I'm installing BPM etc. onto Red Hat Enterprise Linux (RHEL) and Linux is …. Linux.So the approach to install BPM, and it's dependenc

This harks back to a VERY old post: -Testing Times with Telnetwhich was penned back in 2010.Since I've upgraded to macOS High Sierra, I've lost the FTP and Telnet clients.Ordinarily that wouldn't be a problem but ….Telnet is often useful for testing ports e.g. telnet localhost 9443.Thankfully, we have a solution ….

IBM Cloud Private - Tinkering with Vagrant
Mon, Nov 13th 2017 3:11p   Dave Hay
So I've been on a slow boat to IBM Cloud Private, over the past few weeks, and am continuing to self-enable in my "spare" time ( my formal enablement starts next week ). Looking at this: -Source: IBM Cloud Private 2.1.0 - Architectureit was clear that I really needed a few boxes onto which to actually install ICP.Whilst it is possible to run everything on one box ( as per this IBM Cloud Private - My first foray ), I thought that I really should do things properly.So, starting with Beast, whic

Whilst following this online course: -LFS132x Introduction to Cloud Foundry and Cloud Native Software ArchitectureI was tinkering ( man, I love that word ) with Cloud Foundry ( CF ).Now it's been a while and I've been through a macOS upgrade from Sierra to High Sierra ( wonder if there's a clue there ? ).So this time around, I'm seeing "Segmentation Fault: 11" : -cf versionSegmentation fault: 11cf loginSegmentation fault: 11which cf/usr/local/bin/cfls -al `which cf`-rwxr-xr-x 1 root whee

Installing IBM DB2 on Linux using IBM Installation Manager - Fun and Games
Wed, Nov 8th 2017 3:49p   Dave Hay
I've installed DB2 a million (!) times over the past 17 years, since I joined what was then IBM Software Group.However, I've almost always installed it using the DB2 installation binaries and response files.For a long time now, it's been packaged with IBM BPM, and other products, and thus suitable to be installed using IBM Installation Manager (IIM).So now I'm trying that ….One thing of which to be aware; DB2 is typically only ever installed as root, which means ( to me, at least ) that BP

Hmmm, why can't root uninstall IBM DB2 ?
Wed, Nov 8th 2017 1:00p   Dave Hay
I'm cleaning up a VM, and looking to remove DB2 11.1: -/opt/ibm/db2/V10.5/install/db2_deinstall -aDBI1149E To execute this program, you must be the owner of the installation copy.Explanation: The current DB2 copy was not installed by the user who is running theprogram.User response: Log in as the user who installed the current copy of DB2 and rerun thecommand.Given that I'm doing this as root, I'm wondering "Whaaaaat?"So I dug further …/opt/ibm/db2/V10.5/install/db2lsInstall Path

Using curl to drive a SOAP-based web service
Mon, Nov 6th 2017 8:40p   Dave Hay
As part of some tinkering (!) with IBM BPM 8.6, specifically to test a SOAP-based Web Service, as exposed ( exported ) by a SCA module, I wanted to quickly test the service without needing to start/use SoapUI each and every time.Thankfully, there's a curl for that …I'd checked the SCA Module to check the Endpoint Address of the SCA module: -and then hit the ?wsdl action to pull back the WSDL itself: -https://bpmdb.uk.ibm.com:9443/CanaryWeb/sca/callTheCanary?wsdlThis auto-expands to this URL:

Amazon Web Services and a Salutary Learning Experience
Fri, Nov 3rd 2017 8:44a   Dave Hay
I received a small but costly reminder that little in life is free this AM.Whilst indulging in my usual bout of cross-trainer ( #GymOClock ), I checked my emails and saw one purportedly from Amazon Web Services (AWS), suggesting that I owed them $56.31.Being a cautious type, I did NOT click on the links in the email, but instead logged into my AWS dashboard: -https://console.aws.amazon.com/ec2and navigated across to the Billing Dashboard: -https://console.aws.amazon.com/billing/homeLo and behold
