VMware Shared Folders - Now why did I not know that ?

I'm digging into VMware Shared Folders using Fusion on one of my Macs.

Specifically, I was trying to work out how to mount a Shared Folder called Repository as /Repository within the Red Hat Enterprise Linux guest, rather than having it appear as /mnt/hgfs/Repository.

Whilst there's nothing wrong with the default, it does tend to get in the way of scripts, and appears inconsistent when compared with a non-Fusion environment.

This article: -


on VMware.com led me here: -

/sbin/mount.vmhgfs -h

Usage: mount.vmhgfs <sharename> <dir> [-o <options>]
Mount the HGFS share, specified by name, to a local directory.
Share name must be in host:dir format.

Options:
  ro                    mount read-only
  rw                    mount read-write
  nosuid                ignore suid/sgid bits
  suid                  allow suid/sgid bits (default)
  uid=<arg>             mount owner (by uid or username)
  gid=<arg>             mount group (by gid or groupname)
  fmask=<arg>           file umask (in octal)
  dmask=<arg>           directory umask (in octal)
  nodev                 prevent device node access
  dev                   allow device node access (default)
  noexec                prevent program execution
  exec                  allow program execution (default)
  sync                  file writes are synchronous
  async                 file writes are asynchronous (default)
  mand                  allow mandatory locks
  nomand                prevent mandatory locks (default)
  noatime               do not update access times
  atime                 update access times (default)
  nodiratime            do not update directory access times
  diratime              update access directory times (default)
  ttl=<arg>             time before file attributes must be
                        revalidated (in seconds). Improves
                        performance but decreases coherency.
                        Defaults to 1 if not set.
  bind                  perform bind mount
  bind                  move an existig mount point
  serverino             Use server generated inode numbers.
  noserverino           Use client generated inode numbers.
  remount               remount already mounted filesystem

This command is intended to be run from within /bin/mount by
passing the option '-t vmhgfs'. For example:
  mount -t vmhgfs .host:/ /mnt/hgfs/
  mount -t vmhgfs .host:/foo /mnt/foo
  mount -t vmhgfs .host:/foo/bar /var/lib/bar


This allowed me to do THIS: -

mkdir /Repository
mount -t vmhgfs .host:/Repository /Repository/
ls -al /Repository/

How to handle SIB messaging engine functionality, if fail over occur at database server side (in case of data store as message store)?

Have I mentioned how good developerWorks Answers is ?

If not, it's really very good.

Here's an example: -


Question

Would like to know more details about Messaging Engine functionality if data base is failed over to other other server. Is there any way to configure the failover database server names in WebSphere Application Server if primary database server is down and secondary take over the DB functionality?

Answer

...
If you are using data store as message store and lost the connection to the database you can tune the detection of database connection loss to decide how messaging engine functionality should behave. If the connection between a running messaging engine and its data store is lost, either due to a failure or because you stop the database for maintenance, you can ensure that the messaging engine functions correctly after the connection is restored, by configuring the server to restart automatically.

Apple Watch - My first few days

This is NOT a review of the Apple Watch, I've not yet had it long enough, and there are FAR better reviews including this: -


and: -


However, I did struggle ( albeit briefly ) to set up Apple Pay.

I've got an iPhone 5s and have the Watch app set up and connected via BlueTooth.

When I tried to set up Apple Pay in the Watch app on the iPhone, I saw this: -


Could Not Connect to Apple Watch
Make sure your Apple Watch is nearby, powered on, and not in Airplane mode.

Having confirmed that both Watch and iPhone were both powered on AND not in Airplane Mode, I was at a bit of a loss.

The watch was showing this: -


which implied that all was well.

In true The IT Crowd tradition, I thought .... ah hah, why don't I try turning it off and on again.

Therefore, I powered off the iPhone, and turned it back on again.

And ....

guess what ?

Yep, it worked.

I'm now up and running with  Pay, ready to go and spend some money :-)

Apple Music, Apple Music, Wherefore Art Thou ?

I'm loving  Music, as people who know me no doubt know.

Having got things nice and smooth on my Mac and on my iPhone, I was somewhat disappointed to find that my chosen music ( that which I'd "liked" and added to my music library: -

did not appear in ... my music library on another iOS device: -


Thankfully the Music app came to my rescue when I attempted to add a song to My Music on the iOS device, I was kindly presented with this: -


That's what I was missing :-)

Off to the Settings app, and select: -


and we're all good to go :-)

IBM Integration Bus - Where's my WSDL ?

I'm playing with HTTP Input and SOAP Input Nodes in IBM Integration Bus 9 right now, which is nice.

I'm following someone else's tutorial: -




In part 2, he says: -

which confused me because I did NOT have the Generate option: -


Then I checked the IBM Integration Bus Knowledge Centre: -


which says, in part: -

Tip: If you need to generate a WSDL document, you must first enable message set development in the IBM® Integration Toolkit. For more information, see Enabling message set development.

I did as instructed, and saw: -


Once I checked the Enable menus for Message Set development box and clicked OK, I was back in the game: -


To be fair, this does make sense, given what the IIB preferences page says: -


The tutorial was written in 2011 for WebSphere Message Broker.

I'll experiment further ....

IBM Application Performance Management - Why no start ?

We saw an interesting issue with a pair of IBM APM agents today, each on a different AIX LPAR.

Each time we tried to start the agent: -

/opt/IBM/ITM/bin/itmcmd agent start yn

( where yn is a particular agent - ITCAM Agent for WebSphere Applications )

we saw: -

Processing. Please wait...
Starting ITCAM Agent for WebSphere Applications ...
KCIIN0198E Unable to start agent. Please, check log file.


When I dug further, I found this: -

java.lang.UnsatisfiedLinkError: net (A file or directory in the path name does not exist.)

in one of the logs in /opt/IBM/ITM/logs.

This most closely resembled this IBM Technote: -


which suggested that the Java Runtime Environment (JRE) might be corrupted.

Acting on this suggestion, I took a backup of a working JRE from another box running the same version of the yn agent: -

cd /opt/IBM/ITM/JRE/
/opt/freeware/bin/tar cvzf /tmp/itm_java.tar.gz aix523/
scp /tmp/itm_java.tar.gz wasadmin@bpmlpar:/tmp

and restored it in place of the allegedly borked JRE: -

cd /opt/IBM/ITM/JRE/
mv aix523 foobar
/opt/freeware/bin/tar xvzf /tmp/itm_java.tar.gz

and, guess what ..... it worked :-)

/opt/IBM/ITM/bin/itmcmd agent start yn

Processing. Please wait...
Starting ITCAM Agent for WebSphere Applications ...
ITCAM Agent for WebSphere Applications started

IBM BPM - Failing to uninstall

I had an interesting, and only half-resolved, issue with an Service Component Archive (SCA) module that I'd created using IBM Integration Designer 8.5.6 and deployed to the in-built IBM BPM Advanced 8.5.6 runtime ( known as the Unit Test Environment or Integrated Test Environment ).

I got into a position where I was unable to publish, start or uninstall an application ( merely a basic SCA module containing an Interface, a MQ Binding and a BPEL flow ).

This is what I saw in the WAS SystemOut.log file: -

I then tried to uninstall the application using an old-but-good Jacl script: -

/opt/IBM/WebSphere/AppServer/profiles/bpmprofile/bin/wsadmin.sh -lang jacl -user wasadmin -password passw0rd -f /opt/IBM/WebSphere/AppServer/ProcessChoreographer/admin/bpcTemplates.jacl -uninstall BPMDemoApp -force

Error stopping and force uninstalling BPMDemoApp: com.ibm.ws.scripting.ScriptingException: WASX7133E: Application uninstall of BPMDemoApp failed: see previous messages for details..


which struck out :-(

<CAVEAT> Don't try this at home, kids</CAVEAT>

Finally, I took the "nuclear" option of physically removing the EAR file: -

cd /opt/IBM/WebSphere/AppServer/profiles/bpmprofile/config/cells/PSCell1/applications
rm -Rf BPMDemoApp.ear/


cd /opt/IBM/WebSphere/AppServer/profiles/bpmprofile/installedApps/PSCell1
rm -Rf BPMDemoApp.ear/


and validated that, at least from a file-system perspective, it had gone: -

find /opt/IBM/WebSphere/AppServer/ -name BPMDemo

which returned NOWT.

<CAVEAT> Don't try this at home, kids</CAVEAT>

The application is still "there" as far as WAS is concerned, as it appears in the Applications perspective in the ISC, but it's not stopping my server from starting, so I can ignore it - for now.

And this is only my personal test VM.
