IBM Java and Health Centrer - There's More
Tue, Nov 21st 2017 5:23p   Dave Hay
Following an earlier post: -IBM WebSphere Application Server - Tuning and Monitoring and Tuning - IBM Health CenterI've been guiding a colleague in the use of HC, outside of WebSphere Application Server (WAS).This time I wanted to show how HC could be used to monitor a Plain Ole Java Object (POJO), specifically a Java class.Here's one I prepared earlier: -HelloWorld.javapublic class HelloWorld{ public static void main(String[] args) { while (true) { System.out.println("Hello, World");

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

Telnet, my Telnet - Or macOS High Sierra, what have you done ?
Tue, Nov 14th 2017 2:04p   Dave Hay
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 ….

Further to my last: -IBM Cloud Private - Tinkering with VagrantI'm now looking at the options to use VMware Workstation ( this is on Linux, rather than my default home of macOS ) instead of VirtualBox.Following this: -https://www.vagrantup.com/docs/vmware/installation.htmlI've installed the appropriate plugin: -vagrant plugin install vagrant-vmware-workstationInstalling the 'vagrant-vmware-workstation' plugin.

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:
