This is the first of a few posts about my voyage of discovery with WebSphere MQ ( now IBM MQ ) Advanced Message Security (AMS), in the context of message authentication and encryption.Thus far, I've broken it twice :-)I'm following this tutorial: -Quick Start Guide for IBM MQ AMS on UNIX platformsand was able to successfully send messages from Alice to Bob, via a MQ Queue Manager.However, I did hit two exceptions: -/opt/ibm/mqm/samp/bin/amqsput TESTQ TESTQMSample AMQSPUT0 starttarget queue is

This has been on my To-Do list for some time.One of my colleagues was looking to configure connectivity between the IBM ODM Decision Center Business Console and an LDAP server.He, like me, is using ODM Advanced 8.8.1.I'd previously installed and configured this version on WebSphere Application Server (WAS) Network Deployment 8.5.5.This is what I have installed: -/opt/ibm/InstallationManager/eclipse/tools/imcl listInstalledPackagescom.ibm.cic.agent_1.8.6000.20161118_1611com.ibm.websphere.IBMJAVA

I was writing a generic ( use anywhere ) script to add a BPM URL to my IBM BPM Advanced 8.5.7 environment.For me, all of the components ( IBM HTTP Server, WebSphere Plugin and WebSphere Application Server / BPM ) are on the same VM.For the record, I'm running the VM on OpenStack.Therefore, I wanted a script that would get the hostname of the VM on which IHS/WAS is running.This served as source: -How can I use Python to get the system hostname?and this was my test script: - foo.jy import socketh

This from IBM: -An out of memory may be observed on a system running WebSphere Application Server on Linux or AIX that is due to ulimit restrictions on number of process/threads per user.

This came up in discussion today, so I thought I'd x-post some relevant links, as I know I'll need them again: -Network File System (NFS) Recommendations for WebSphere Application Server to AVOID DATA LOSS…NFS v4 is commonly used as a reliable storage for the following components of WebSphere Application Server:…The following table lists mount options that are required.

This article has been written by two of my IBM colleagues, and is definitely worth a look: -Increase logging with a custom policy for IBM DataPower in the API Connect assemblyWhen you design and develop custom integration policies, you need to be alerted to any problems with your policies.
