Executing external Python/Jython scripts from within WebSphere Application Server's wsadmin tool

One of my ISSW UK colleagues had asked how to invoke an externally located Python/Jython script from inside the wsadmin tool.

This is different from the normal method of starting wsadmin and directing it to load a file at startup e.g.

$ ./wsadmin.sh -lang jython -c 'AdminApp.list()'

This is subtly different - one is already in wsadmin and wants to go fetch / execute an external script.

Well, thanks to the IBM Connections 2.5 documentation (!), here it is: -

wsadmin>execfile("<$WAS_HOME>/profiles/<DMGR>/config/bin_lc_admin/blogsAdmin.py")

My colleague also pointed out that one can execute OS commands from within a Python shell e.g.

$ python

Python 2.6.6 (r266:84292, May 27 2013, 05:35:12) 
[GCC 4.4.7 20120313 (Red Hat 4.4.7-3)] on linux2
Type "help", "copyright", "credits" or "license" for more information.

>>> import os
>>> os.system("/bin/ls")
ConfigBPM.err   ConfigNetworkPort.err  ConfigPWD_USER.err  License.err
ConfigBPM.out   ConfigNetworkPort.out  ConfigPWD_USER.out  License.out
ConfigLocale.err  ConfigNTP.err  ConfigSSH.err      _nowait
ConfigLocale.out  ConfigNTP.out  ConfigSSH.out      ovf-env.ar
ConfigNET.1.err   ConfigPWD_ROOT.err  ConfigVNC.err      ovf-env.done
ConfigNET.1.out   ConfigPWD_ROOT.out  ConfigVNC.out


So, putting it all together, here's me executing an external Jython script from within wsadmin, where said Jython script gets a directory listing: -

$ /opt/IBM/BPM/v85/profiles/BPMPCDmgrNode/bin/wsadmin.sh -lang jython -user wasadmin -password password

WASX7209I: Connected to process "dmgr" on node BPMPCDmgrNode using SOAP connector;  The type of process is: DeploymentManager
WASX7031I: For help, enter: "print Help.help()"

wsadmin>execfile('/tmp/foobar.py')
Hello World!
Here comes the directory listing
Desktop
Documents
Downloads
Music
Pictures
Public
Templates
Videos
workspace


and here's the Python script: -

$ cat /tmp/foobar.py 
import sys;
import os;

print "Hello World!"

print "Here comes the directory listing"

os.system("/bin/ls")

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

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

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
