Sharing - WebSphere Application Server Liberty Profile and Docker

I was tinkering with Docker this evening, and found this from an IBM colleague, David Currie

WebSphere Application Server Liberty Profile and Docker [PDF]

and, thanks to this, I'm now installing WebSphere Application Server Liberty Profile ( aka WAS Liberty Profile ) on Docker: -

docker run -e LICENSE=accept websphere-liberty

using Boot2Docker on the Mac, as per a previous post here: -

Getting up to speed with Docker and IBM Bluemix

Back the past, again that's why I blog ...

I had cause to refer back to an old post: -

VMware - Where the X is my X ?

this afternoon, when I saw this exception, when using IBM Installation Manager : -

I'm using IBM Installation Manager 1.8.1 : -

/opt/ibm/InstallationManager/eclipse/tools/imcl -version

Installation Manager (installed)
Version: 1.8.1
Internal Version: 1.8.1000.20141126_2002
Architecture: 64-bit

As before, the answer was to add: -

-Dorg.eclipse.swt.internal.gtk.cairoGraphics=false
-Dorg.eclipse.swt.internal.gtk.useCairo=false

to /opt/ibm/InstallationManager/eclipse/IBMIM.ini and retry.

For the record, I also saw the same problem earlier this year: -

Hmmm, USB and  Mac Mini - Not BFFs

I had a wee problem connecting a StarTech USB enclosure ( containing a 512 GB SSD drive ) to my Mac Mini this evening.

The drive never showed up in Finder, in Terminal ( under /Volumes ) or in Disk Utility.

Eventually, the enclosed would throw up a connection error.

In the logs ( sudo dmesg ) I saw: -

...

…

I tried various things, including suspending a running VM and shutting down VMware Fusion 8, but to no avail.

In the end, I moved the drive from one USB port to another.

( the arrow indicates the from, the connected USB cable indicates the to )

Strange but true ;-)

IBM AIX Support Center Tools

I saw this earlier: -

AIX Support Center Tools provides information about widely used data gathering tools and recommendation tools that are used by AIX system administrators in conjunction with the IBM support center team. The gathering tools help reduce the amount of time spent during initial problem determination. The recommendation tools help provide health check reports or cross-product compatibility information.

Data gathering tools

zsnap

The zsnap utility delivers all the benefits of the standard snap command and captures additional debugging data in an easily understood format. IBM's world-class AIX support centers have teamed up to deliver a more fully integrated tool for data gathering, one that has already been proven to reduce the time needed to resolve customer problems. IBM recommends that you install zsnap before you call IBM technical support.

devscan

The devscan tool facilitates the debugging of storage problems by rapidly gathering a great deal of information about the SAN. It then displays the information in an easy-to-understand manner. You can run devscan from any AIX host, including VIO clients, or from a VIOS.

perfpmr

The perfpmr tool is used extensively by the AIX technical support centers. This package contains a set of tools and instructions for collecting the data needed to analyze performance problems. IBM may ask you to download and use this tool.

pdump

The pdump script extracts information from the running process using kdb command and other AIX tools.

snap

The snap command is included with the operating system. Snap captures system configuration information for AIX and PowerHA. Product technical support centers regularly request snap output to identify and resolve problems. Snap output can be delivered to IBM in portable archive exchange format (pax).

Ask the Experts Replay: Understanding HA Manager, WLM, and ORB in WebSphere Application Server

The High Availability Manager (HA), Work Load Management (WLM), and Object Request Broker (ORB) component provide several core features in WebSphere Application Server. This session is open to discuss the concepts, issues, and best practices of each component.

Bash - Using Variables in Sed

Set a variable

export NAME=DAVID

Validate the variable

echo $NAME

DAVID

Initialise a file

echo "DAVE" > foobar.txt

Validate the file contents

cat foobar.txt

DAVE

Replace the contents of the file with the contents of the variable

sed -i'' "s/DAVE/$NAME/g" foobar.txt

Validate the file contents

cat foobar.txt

DAVID

This works with Bash 4.1.2(1)-release on RHEL 6.6.
