Oracle Universal Content Management Handbook

A new book about Oracle UCM has been published by Packt, I have been asked by Packt to review this book. I found this book is very interesting especially if you are new to UCM or you didn't get the chance to review all UCM capabilities. I used to give UCM trainings with Oracle, I can admit that reading this book will give the same knowledge you may get from trainings.

But I was wishing that this book will cover Oracle UCM 11g, where it covers UCM 10g, however almost all information in that book can be applied to 11g too.

Stars in Kuwait

I am currently working in a project in Kuwait, they are using Star Names for naming servers' hostnames. For me it is the first time I work with stars :D now I am interested in meaning of star names because of this project thanks to Jasem who is owner of this idea.

I was searching for star names and I came across an interesting website WikiSky. I like it so much and I think it deserves a look, you can get which stars is above you right now, can you imagine?

Now I will list the stars (servers) which I am working with

Chara          Joy Chort          Small rib Electra        Amber/Shining Homam      The high-minded man Nunki         "of Enki" (Sumerian god of waters & of most ancient city of Eridu) Porrima      Roman goddess of childbirth Yildun        Star Lesath        Sting Matar        Rain By the way, after I saw the meaning of some stars, I am surprise, because some names are Arabic names like Matar. Anyway I liked the idea of using the star names for servers' hostnames.

Missing Configuration for Integration between OIM and ORM with JBOSS

I was facing an error after doing the integration between Oracle Identity Manager and Oracle Role Manager where OIM installed on Linux server and ORM in Windows server, here is a snapshot from the log

03:39:40,216 WARN  [IntegrationUtilities] No plugin configuration files found in /oracle/idm-home/jboss-4.2.3/bin/c:\ORMINT_HOME\/config
03:39:40,217 ERROR [TASK] Class/Method: SchedulerBaseTask/run encounter some problems: {1}

I faced this error before when I installed OIM on windows, but for a quick way to solve the problem I moved ORMINT_HOME (ORM Integration Library location on OIM server) to the default location C:\ORMINT_HOME but after we changed OIM server to be Linux server, I had to face that issue again.

I tried to find if someone faced that issue before or not I didn't find help, even I opened Service Request on Metalink but without any help. That's because ORM is a new product and there are only few implementations for it (by the way I am not a fan for that system).

The solution for this error is very simple but not mentioned in documentation, there is a system property that needs to be added to JBoss and it will be used by OIM for integration purposes with ORM. That property is ORMINT_ROOT_DIR and it will be added with a value to properties-service.xml file (you can find it under /server/default/deploy )

<attribute name="Properties">
      ORMINT_ROOT_DIR=/oracle/idm-home/ORMINT_HOME
<\attribute>

AD integration in OpenText Hummingbird vs Oracle UCM

I am working in Oracle IDM project currently, and I have to provision users to Hummingbird and Hummingbird in this case integrated with Active Directory. So I were in my mind making a comparison between Oracle UCM and OpentText Hummingbird and I want to share it here.

In Oracle UCM, it is a full integration why because user roles and accounts will be represented in AD as security groups, so I want to give an AD user the contributor role, just assign to him contributor security group form inside AD. Also you can make a custom user attributes from inside UCM to AD user attributes like user manager or any other attribute.

In OpenText Hummingbird especially with Document Management module and Records Management modules, the admin have to import users from AD manually and assign security groups and permissions from inside the system, which means it is not full integration, Hummingbird is just using AD as a repository of users info not a repository for security.

Another thing Oracle UCM is like an open source application it is open, you can change any functionality you want, its database schema is not sealed and the schema is very easy to be used and modified. But Hummingbird's database is not allowing that, if you tried to add new records or delete records, the system will throw exceptions and errors.

In my opinion, Oracle UCM is one of the best applications you can integrate with. So If I am a decision maker I will always choose UCM because of integrations easiness.

JMS error sending message to queue/orm/IncomingEventQueue

I was getting the following error when I try to create an Oracle Identity Manager user after integrating with Oracle Role Manager (both OIM and ORM are using JBoss as the application server). I took from me a lot of time to discover the cause of that error
 

ERROR [oracle.iam.rm.imframework.oimjavatasks.ReconcileEntityAdapter] General exception: JMS error sending message to queue/orm/IncomingEventQueue
java.lang.Exception: JMS error sending message to queue/orm/IncomingEventQueue
    at oracle.iam.rm.imframework.util.JMSUtil.sendMessage(JMSUtil.java:96)
    .......
Caused by: org.jboss.mq.SpyJMSException: Cannot authenticate user; - nested throwable: (java.net.NoRouteToHostException: No route to host: connect)
    at org.jboss.mq.SpyJMSException.getAsJMSException(SpyJMSException.java:72)
    .......
Caused by: java.net.NoRouteToHostException: No route to host: connect
    at java.net.PlainSocketImpl.socketConnect(Native Method)
    .......

The cause of the error is that in the test server where I installed Oracle Role Manager I have more than one IP address for the server and I was binding JBoss to all IP(s) by running it using the following command
run.bat -b 0.0.0.0
The solution is to bind JBoss to only one IP as the following
run.bat -b 192.168.220.1

Sun Identity Manager and Oracle Identity Manager

As all of us know, Oracle bought Sun and the deal has been closed completely. I am currently working with Oracle Identity Management (as well as Oracle UCM) and I am interested to know Oracle's plan for IDM after merging. I found a blog post that talks in brief about that I recommend you to read it, click here.

The conclusion Oracle will keep its IDM solutions as a strategic solutions and it will re-brand Sun IDM solutions.

Java Decompiling

When I face frustrating bugs that comes because of the misleading exceptions, I go to the magic method which is decompiling the class that cause the error, and take a quick look there. But note I don't prefer going deeper to understand the class and the library I am decompiling.

I am using JD-GUI and I'd like to thank the people who created it and made it available for free.
