dd_in_ear_load_EXC_ Exception when deploying Maximo ear file in WebSphere

I was trying to configure App security in Maximo so I updated the:

·         applications\maximo\maximouiweb\webmodule\WEB-INF\web.xml

·         applications\maximo\mboweb\webmodule\WEB-INF\web.xml

and when I tried to redeploy the ear file I got the following error after I browsed to the ear file.

The exception dd_in_ear_load_EXC_ ocurred. Check log for details.

The issue was that I had uncommented both FORM and BASIC login in the applications\maximo\maximouiweb\webmodule\WEB-INF\web.xml.  If you get this error go back and check the applications\maximo\maximouiweb\webmodule\WEB-INF\web.xml and make sure you only have one <login-config> uncommented.

IBM HTTP Server Documentation

I was watching the IBM WebSphere Application Server V6 Web Server Definition and Plug-in Education Assistant video and ran across this link that provides the download info and support documentation for the last 5 versions of IBM HTTP Server.

Getting Started with MQTT

This is the first in what I hope turns out to be a series of posts about one geek's journey into MQTT and let me tell you it was big doings tonight !!

I was successfully able to publish and subscribe a MQTT message for the first time ! It was not as tough as I thought it would be but only because of the IBM redbook Building Smarter Planet Solutions with MQTT and IBM WebSphere MQ Telemetry The first step was to launch a terminal client from my Ubuntu box that has mosquitto installed.

I then typed in the command to publish  "mosquitto_pub -t samples/topic01 -l"
 (well I copied the exact description of the command from the redbook which is mosquittopub and I got an error No command 'mosquittosub' found, did you mean: mosquitto_pub. I am very new to Linux and do not know why the redbook said one thing and another work, so I will have to add this to the research list down the road.  )

I then opened a second Terminal and entered the command for a subscription
mosquitto_sub -t samples/topic01

I then entered a message in the publish screen and pressed enter.

and low and behold it appeared on the second screen ! Page 46 of the redbook says that "The examples assumes that the client and the server are on the same machine" I will be interested to see what makes this assumption work but will have to save that for another night. 

WebSphere Messaging Engine, Locking and Troubleshooting

I have run into a few issues with WebSphere Messaging Engines this year and this had leaded me to a few different resources on the subject. The best place by far is Ty Shrake’s  webcast replay of “WebSphere Application Server - Service Integration Bus Messaging Engine Data Store Connectivity Problems and Solutions” http://www-01.ibm.com/support/docview.wss?uid=swg27020333 Ty does a really great job of describing messaging engines, datastore,  locks and how to troubleshoot them.

IBM’s info center has a good resource that describes locking of data stores. http://pic.dhe.ibm.com/infocenter/wasinfo/v6r1/index.jsp?topic=%2Fcom.ibm.websphere.nd.doc%2Finfo%2Fae%2Fae%2Fcjm0450_.html

Understanding Maximo LDAPSYNC

Great technote from IBM on how the LDAPSYNC process syncs with Microsoft Active Directory Global Catalog. When I first started looking into this I was a little confused by the XML in the LDAPSYNC cron task. I was not sure what to add and where to add it but this cleared up much of my confusion.  Interesting points I found were

• LDAPSYNC connects to the Microsoft Global Catalog on port 3268
• LDAPSYNC can be configured to access the LDAP server directly, however; this does not follow Microsoft recommendations
• Maximo administrators can map additional information from the LDAP server to Maximo using the SYNC task.
