DB2 HADR - Updating Host Names
Thu, Sep 3rd 2015 10:29a   Dave Hay
Following my earlier posts, I've now gone to another level, cloning my DB2 HADR server ( the original standby server ) and thus creating TWO DB2 servers, one dedicated as primary and one dedicated as standby.Of course, the delights of HADR mean that I can switch back and forth, and that's the objective - I want to have a single VM hosting WebSphere Application Server ( IBM Business Monitor ) and TWO VMs hosting DB2, so that I can properly test failover by physically turning off a VM ( shutdown

DB2 HADR - A Clash of Primaries

I had fun with DB2 this afternoon, following an unplanned restart of BOTH of my DB2 servers.In essence, neither the primary nor the standby wanted to be ... the primary.This is what I saw for one of the two databases: -On original primarydb2pd -hadr -db cognosDatabase Member 0 -- Database COGNOS -- Standby -- Up 0 days 00:11:28 -- Date 2015-09-02-18.53.28.860276 HADR_ROLE = STANDBY REPLAY_TYPE = PHYSICAL HADR_SYNCMODE =

WebSphere Application Server 8.5.5 and DB2 10.5 - High Availability for Disaster Recovery - Like Manuel, I learn ....
Wed, Sep 2nd 2015 11:01a   Dave Hay
I've been testing, experimenting and documenting my experiences with IBM DB2 10.5, specifically with the High Availability for Disaster Recovery (HADR) configuration, in the context of making a WebSphere Application Server (WAS) configuration more resilient.To that end, I've been scripting the necessary configuration to allow WAS to use the DB2 Automatic Client Reroute Options: -in order that WAS can connect to another DB2 server within the "cluster" in the situation where the primary server

VMware Fusion on Mac OS X - Sleep, no wake-ee
Mon, Aug 31st 2015 2:49a   Dave Hay
I've had a few problems with my Mac ( a 15" 2012 MacBook Pro Retina ) when I try and resume ( wake ) the laptop up whilst I've got VMs running.I'm using VMware Fusion 7.1.2 and OS X 10.10.5.Typically the symptom is that the Mac fails to give me a login prompt, and I have to hit the power button. Once it's booted up, and I log in, I find that all my running apps have stopped, and try to automatically restart.This means that any open documents go into recovery mode, and the VMware VMs themsel

WebSphere Application Server - High Availability Manager - What Is It Good For ?
Thu, Aug 27th 2015 7:15a   Dave Hay
I've just posted to the GWC blog here: -WebSphere Application Server - High Availability Manager - What Is It Good For ?This has come up in the past few weeks, as I've been configuring WebSphere Application Server (WAS) Network Deployment, aka WAS Full Profile, to store it's transaction log data in DB2 database tables.This requirement exists because, for resilience and high availability, one typically deploys a WAS cell across multiple logical or physical nodes.Want to know more ? You know wh

Building and deploying business monitor models for IBM Business Process Manager V8.5 processes
Thu, Aug 27th 2015 3:55a   Dave Hay
I saw this on Twitter and thought of .... well, everyone :-)Learn how you can generate a monitor model from IBM® Business Process Manager V8.5 and deploy the monitor model in an IBM Business Monitor server installed in a separate WebSphere® cell. This content is part of the IBM Business Process Management Journal.IBM Integration Designer (hereafter called Integration Designer) provides the capability to generate a monitor model from your IBM Business Process Manager (BPM) project. This tutoria

Podcasts app in iOS - Sunk, not syncing
Tue, Aug 25th 2015 2:33p   Dave Hay
OK, so I managed to break, and then fix, the Podcasts app in iOS 8.4.1 on an iPhone 5s.The lesson learned ? Don't do this in iTunes as it seems to stop the Podcasts app from downloading updates to the podcast feed.In fact, it's worse than that ( it's dead, Jim ) in that the app hangs altogether, and then completely crashes.I tried the IT Crowd trick: -IT Crowd - Have You Tried Turning It Off And On Again? ( YouTube )but to no avail.The solution appeared to be related to the fact that BOTH i

Comment lines: Encrypting WebSphere Application Server system passwords — if you insist
Thu, Aug 20th 2015 2:58a   Dave Hay
This from my IBM colleague, Martin Lansche: -IBM® WebSphere® Application Server stores system passwords in files that are simply encoded. To support clients who want to implement their own password storage mechanism, WebSphere Application Server has provided a System Programming Interface (SPI) to do so. Encrypting these system passwords can provide some marginal additional security benefits for a specific class of vulnerability (poorly implemented application code), but it cannot provide defe

Wed, Aug 19th 2015 8:02a   Dave Hay
This is in the context of an IBM Business Process Manager Advanced 8.5.5.0 installation on AIX.I'd noticed a spurious exception in the First Failure Data Capture (FFDC) logs of both members of the AppCluster: -19/08/15 09:44:01:200 BST] FFDC Exception:org.springframework.jdbc.UncategorizedSQLException SourceId:com.ibm.ws.uow.UOWManagerImpl.runUnderNewUOW ProbeId:934 Reporter:com.ibm.ws.uow.UOWManagerImpl@f8de0965 org.springframework.jdbc.UncategorizedSQLException: PreparedStatementCallback;
