Setup:
2 HTTP Servers
1 Load Balancer between 2 HTTP server and 2 MobileFirst servers
2 MobileFirst server 8.0 s on Liberty Farm 8.5.5
IBM DB2
i am facing an issue with session affinity during mobilefirst server failover. when it failed over to other server, the console says the session has expired.
i followed the below link to configure the session persistence for Liberty but the procedure is not clear. i created sessions database but it doesn't create any table under that.
http://www.ibm.com/support/knowledgecenter/SSEQTP_8.5.5/com.ibm.websphere.wlp.doc/ae/twlp_admin_session_persistence.html
the web plugin config.xml files is configured to point so it's like HTTP server > LB > mobilefirst servers.

We are using Websphere liberty 20.0.0.12 and spring boot (parent) version 2.0.5.
I can find the connection pool information in the JConsole.
How can I print Websphere connection pool information in application logs?
(Read comments of approved answer if using liberty server instead of traditional websphere application server)
IBM support doc at https://www.ibm.com/support/pages/how-enable-connection-pool-trace-websphere-application-server describes how to enable printing of various connection pool stats in the trace log for traditional WAS, for Liberty, you'll use the same trace specification WAS.j2c=all:RRA=all(you don't need Transaction) and put a logging element in your server config file (typically server.xml). See Liberty doc at https://openliberty.io/docs/latest/log-trace-configuration.html for more info.
My app runs well on Worklight Development Server, but not on WebSphere Application Server V8.5 Liberty Profile.
I tried both Oracle JDK and IBM JDK, there was no difference.
There was no problem connecting to the server with jconsole, although I had to connect without ssl.
On Eclipse Console,
[2014-07-11 17:18:10] Starting build process: application 'U1', all environments
[2014-07-11 17:18:12] Application 'U1' with all environments build finished.

Thank you.
I do not know how the Studio deploys to an external Liberty server.
You could also:
Install Worklight Server and deploy using
- the Server Configuration Tool
- or the ant tasks (provided by the Worklight Server installer)
- or manual procedure documented at https://www-01.ibm.com/support/knowledgecenter/SSZH4A_6.2.0/com.ibm.worklight.installconfig.doc/install_config/t_wlconsole_install.html
The manual procedure may give you hints about what is missing in your External Liberty Server.
It could be:
- rest connector and it's configuration https://www-01.ibm.com/support/knowledgecenter/SSZH4A_6.2.0/com.ibm.worklight.installconfig.doc/install_config/t_optional_config_app_server_liberty.html
- JNDI properties so that Liberty can use the REST connector (step 3 at https://www-01.ibm.com/support/knowledgecenter/SSZH4A_6.2.0/com.ibm.worklight.installconfig.doc/admin/t_configuring_liberty_profile_for_wladmin_manually.html )
On the 6.1 server I run...
$AdminTask exportWasprofile {-archive c:/tmp/my.car}
On the 8.5 server I see...
$AdminTask importWasprofile {-archive c:/tmp/my.car}
WASX7015E: Exception running command: "$AdminTask importWasprofile {-archive c:/
tmp/my.car}"; exception information:

Is there something special I have to do to properly migrate profiles? Is there a place I can look to get more info as to what is going wrong?
From IBM WebSphere Application Server Migration Toolkit's website:
The IBM® WebSphere® Application Server Migration Toolkit is a suite of
tools and knowledge collections that enables your organization to
quickly and cost-effectively migrate to WebSphere Application Server
V7, V8, or V8.5, whether from a previous version of WebSphere
Application Server or competitive application servers including Apache
Tomcat Server, JBoss Application Server, Oracle Application Server,
and Oracle® WebLogic Server.
You should use it as it's bundled in WebSphere Application Server 6.1 (and higher) and offers two scripts that help you in the migration: WASPreUpgrade and WASPostUpgrade.
WASPreUpgrade "saves the configuration of a previously installed version of WebSphere Application Server into a migration-specific backup directory." while WASPostUpgrade "retrieves the saved configuration that was created by the WASPreUpgrade command from the backupDirectory that you specified." (quoting their pages).
Although they might be using wsadmin/Jython, I think you may have more success with these two command-line utilities.
I have a situation where every request handled by my web-application that is deployed on IBM WebSphere Application Server 8 has to talk to a remote system via a Socket connection. Is possible to create a connection pool for the Socket connections in IBM WebSphere Application Server 8. If yes, how?
Environment: Java 1.6, JEE5, IBM WAS8
WebSphere Application Server doesn't have builtin support for pooling arbitrary connections. It does support JCA and its connection pooling, so probably the closest you'll get is to write your own resource adapter that opens connections. That's no exactly trivial, and unfortunately, I'm not aware of any libraries that already do this.
I am trying to configure clustered JMS on Weblogic 10.3.4.
I have a 4 node cluster plus my AdminServer already configured. I also have my JMS already configured and targeted to AdminServer. From reading the Weblogic documentation, I am not clear as how to cluster the JMS server. Could someone please explain how?
There is no 'clustered JMS server'. There are WebLogic clusters, the Admin Server & Managed Servers and then JMS Servers. JMS Servers are a configuration construct within a Managed Server.
In order to cluster JMS in WebLogic each managed server in the cluster needs a JMS server. Then, when you create JMS resources you can either use default targeting or subdeployments. If you use default targeting then it will implicitly target the resource to the JMS server for each managed server in the cluster. If you have more than one JMS server per managed server, the behavior can be different, but you likely don't need that. Alternatively, you can use subdeployments to target specific managed servers or JMS servers, but not likely needed for your purposes.
