WebSphere Application Server - Managing the Service Integration Bus using Python
Wed, Apr 13th 2016 2:55p   Dave Hay
A friend asked me: -Hi Dave -- do you know the AdminConfig.getid(type:scope) to get a SIBus engine? not sure what type and scope need to be passed in It took me a wee while, but I shared this: -for bus in AdminTask.listSIBuses().splitlines(): name=AdminConfig.showAttribute(bus, "name") print AdminConfig.getid("/SIBus:"+ name) which results in: -BPM.PCCellDe1.Bus(cells/PCCell1/buses/BPM.PCCellDe1.Bus|sib-bus.xml#SIBus_146

IBM WebSphere Plugin - GSK_ERROR_BAD_CERT and GSK_INVALID_HANDLE after an upgrade
Tue, Apr 12th 2016 1:25a   Dave Hay
During a recent transition from SHA1 to SHA2 signature algorithms *AND* an upgrade from WebSphere Application Server (WAS) 8.5.5.4 to 8.5.5.8, we hit an interesting challenge yesterday.We're using IBM HTTP Server (IHS) and the WebSphere Plugin on one AIX LPAR, fronting IBM Integration Bus (IIB) on another LPAR.We've got a set of IIB flows, all of which are being offered up via IHS through the WebSphere Plugin configuration.Once the 8.5.5.8 upgrade ( including IHS and Plugin ) was completed, we

IBM Business Monitor - CWMAX4203E: RESTSecurityAdminMBean instance was not found
Fri, Apr 8th 2016 8:14a   Dave Hay
I saw this error earlier: -CWMAX4203E: RESTSecurityAdminMBean instance was not found.whilst checking my Monitor models, in IBM Business Monitor 8.5.5, after making some SSL/TLS related changes between WebSphere Application Server (WAS) and DB2.I saw this when I navigated to Applications > Monitor Models.This caused me to briefly panic.Thankfully, I found that someone had seen a similar issue, documented in a Problem Management Report (PMR).For context, in order to make my configuration change

Book Review - The Purpose of Change is Problem Solving
Wed, Apr 6th 2016 4:13p   Dave Hay
This is the latest in my series of relatively infrequent book reviews for the British Computer Society: -The Purpose of Change is Problem SolvingI chose this book mainly based upon the title, to which I related as aninveterate solver of problems.Whilst the book is absolutely about problem solving, it wasn't quitewhat I expected. In this book, the author, Janos Korn, digs deeply intothe use of language, including semantics, natural language andstructure.Thus I found the book to be of somewhat li

My Cognos has fallen and can't get up
Tue, Apr 5th 2016 8:21a   Dave Hay
Purely FYI, in case you hit this problem, someone (!) managed to break my IBM Business Monitor 8.5.5 installation over the weekend, most likely when the underlying AIX LPARs were shut down and moved from one physical box to another.I saw a bunch of nasty exceptions in the Cognos instance pogo logs: - 2016-04-05 09:21:54.467 FATAL [.authorization.AuthorizationAdapterFactory] Thread-95: Unable to initialize the Access Control Modulecom.ibm.cognos.internal.camaaa.accesscontrol.AccessControlExceptio
