Please feel free to view the replay of our July 29 webcast A Technical Introduction to the IBM WebSphere Liberty Profile at your convenience. The presentation will be available for download shortly.
Question 1:Suresh Rachakonda: Can applications running on Liberty Profile not connect to WebSphere MQ Queue Managers?
Alex Mulholland: Yes the wmqJmsClient-1.1 featue in the WAS (base) edition provides transactional integration with WMQ.
Question 2:
Mike Lee: Does WAS8.5.5 support "mongodb"?
Alex Mulholland: Yes the mongodb-1.0 feature in the WAS (base) edition allows the mongo db configuration to be put in the server.xml file and then used by all applications.
Question 3:
Mike Lee: Where I can download adminCenter for Liberty profile?
Alex Mulholland: From the
Liberty Repository.
Question 4:Phillippe Richard: Is it a download also for z/OS ?
Alex Mulholland: At this time Liberty can be used on z/OS using Installation Manager which can also apply the features in the Liberty Repository to a z/OS installation. If you would like an archive install for Liberty on z/OS please
submit a request.
Question 5:Rene Zubcevic: Is there also support for the IntelliJ development tool?
Alex Mulholland: Yes Intellij IDEA has a plugin for Liberty so applications can be tested easily. Check
here for more details.
Question 6:Debbie Tomlin: Is Liberty available on IBM i?
Alex Mulholland: Yes Liberty is supported on all the same platforms as the full WAS profile plus Mac OSX for development only.
Question 7:Russ Engel: WAS ND is depicted as only being additional features on top of Base which is on top of Core. Does this mean that any capability we see available for Liberty development (many of the DevOps features are coming to mind) are available for WAS ND?
Alex Mulholland: Yes that's correct. The only features that are not in the ND edition are the features for z/OS.
Question 8:
Debbie Tomlin: Is there a cost to use Liberty in production?
Alex Mulholland: The Liberty profile is included in all the WAS editions so the prices are the same as for the full profile server. The Liberty Core edition does not contain the full profile and is a lower price point than the WAS (base) edition.
Question 9:Phillipe Richard: Is the new admincenter also available for z/OS?
Alex Mulholland: Yes it is the same on all platforms.
Question 10:Kanuri Murty: How does JVM startup of WAS 8.5.5.x Full Profile compare with that of the Liberty Profile?
Alex Mulholland: The full profile initializes all services resources and applications fully before opening for requests so it takes longer to start than the Liberty profile. The start time depends on the applications and resources that are configured to the server.
Question 11:Min Zhang: What is Wily Introspect? Did you mean Introscope?
Alex Mulholland: Yes CA Wily Introscope.
Question 12:Suresh Rachakonda: Is CA Wily Introscope now bundled with Liberty Profile?
Alex Mulholland: They are not bundled together but they do work together. See
here for more information.
Question 13:Dharmendra Himanshu: What the SPI available and where we can find the information?
Alex Mulholland: The SPI is documented in the knowledge center section called '
Extending the Liberty profile.' The classes and javadoc are packaged in the product install under the dev/spi/ directories.
Question 14:Raymond Chiang: Does it support On-Demand- Router (ODR) ?
Alex Mulholland: No.
Question 15:Krishna Kishore: I'm looking for LDAP configuration.
Alex Mulholland: There are sample configuration snipets in the repository
this view lists the LDAP ones.
Question 16:Shahrokh Nezamzadeh: Does CICS and CICS Transaction Gateway also support Liberty profile?
Alex Mulholland: CICS actually embeds Liberty as a web application server in the CICS JVM process. CTG works with the Liberty profile.
Question 17:Hari Gentyala: Can Liberty profile be used for integrating with Network Deployment and clustering etc?
Alex Mulholland: Yes Liberty profile servers can be managed by a WAS full profile DMgr in a traditional ND cell under the 'assisted management' model which provides light-touch management and dynamic clusters.
Question 18:Raymond Chiang: Does it have Health Monitoring as the WAS 8.5 full profile?
Alex Mulholland: There is some basic health monitoring provided through assisted lifecycle but not as much as for full profile.
Question 19:Suresh Rachakonda: How is Liberty Profile licensed?
Alex Mulholland: The same as the full WAS profile as well as the Liberty core edition.
Question 20:Subramanian Parlikkad: Can we use clustering feature of WAS ND in WAS 85 liberty?
Alex Mulholland: There are two ways to do this. Liberty profile servers can be managed by a WAS full profile DMgr in a traditional ND cell under the 'assisted management' model which provides light-touch management and dynamic clusters. Liberty clusters can also be created within a Liberty Collective which is a pure liberty solution.
Question 21:Zahur Khokhar: Can we install Liberty profile if we have WAS 7
Alex Mulholland: Yes if you have capacity within your licensing you are entitled to use WAS 8 and 8.5 as well as 7 Liberty and Full profile.
Question 22:Gregory Boeschen: How do application deployments work in a large liberty environment? Do you get one file system the way you want it and then zip it up and copy it to other servers?
Alex Mulholland: Yes that is probably the most popular practise. Apply updates to your 'master image' and copy it out to all your host machines.
Question 23:Azhagesa Gurusamy: Will the wsadmin commands work with liberty profile?
Alex Mulholland: No it will not.
Question 24:Michael Stansell: Where on slide 12 is the full EJB support (stateless session beans not Local)?
Alex Mulholland: Full EJB support is not yet available but will come with the full Java EE implementation that IBM has announced. When it is delivered it will be in the WAS (base) edition.
Question 25:Markus Korczyk: From a developers perspective why they should not use open source AppServers like TomCat or JBoss and what would be a good argument to convince them using WebSphere Liberty?
Alex Mulholland: There are a number of benefits to using Liberty: 1) unlike tomcat the Java EE technologies are integrated tested and supported by IBM but you can still package your own versions if you want without classloader issues 2) the server is much smaller and more flexible than jboss 3) the configuration is much simpler (one small xml file for liberty seven for tomcat more for jboss).
Question 26:Alex Kulczycki: I did the Getting Started with Liberty tutorial a few months ago and started up the HelloWorld app successfully but when I pointed a browser to the app on localhost I got a 404 not found error. How would I go about diagnosing and fixing this?
Alex Mulholland: The Liberty server console will print the URL for all running web applications I would start from that to get the correct context_root and then look at the application (web.xml or servlet annotations) to add the servlet paths.
Question 27:Adrian Vergas: Can I migrate any application from WAS 6.1 to the latest Liberty Profile ?
Alex Mulholland: The
Liberty Migration Tools will scan your application and tell you whether it will require any changes to run on Liberty.
