I have application running in Websphere Liberty and uses DB2 in Z/oS. I have set the db2 driver proerties in DB2JCCConfiguration.properties .How can make sure that the server has picked up properties I have set .I am not sure how to verify the trace to see if the properties are applied to server
To configure a datasource (for any backend DB) with Liberty, you can add configuration like this to your server.xml:
<featureManager>
<feature>jdbc-4.2</feature>
</featureManager>
<library id="driver-library">
<fileset dir="/path/to/driver/dir" includes="*.jar"/>
</library>
<dataSource id="DefaultDataSource" jndiName="jdbc/myDB">
<jdbcDriver libraryRef="driver-library"/>
<properties.db2.jcc serverName="example.db.hostname.com" portNumber="50000"
databaseName="myDB"
user="exampleUser"
password="examplePassword"
currentSchema="xyz"
fullyMaterializeInputStreams="true"/>
</dataSource>
To test if your configuration is correct and that your Liberty server can connect to your DB2 database, add the following configuration:
<featureManager>
<feature>appSecurity-3.0</feature>
<feature>restConnector-2.0</feature>
<feature>jdbc-4.2</feature>
</featureManager>
<!-- Any security mechanism can be used, <quickStartSecurity> is the simplest -->
<quickStartSecurity userName="admin" userPassword="admin"/>
And then go to: https://localhost:9443/ibm/api/validation/dataSource/DefaultDataSource
(this assumes your <dataSource> id is DefaultDataSource)
For more info, see this cheat sheet: https://aguibert.github.io/openliberty-cheat-sheet/#_ibm_db2
I attempted to create a new project in kie-workbench (6.2.0.Final) and deploy it to the remote kie-server (6.2.0.Final). I create the container via the workbench then hit the "start" button for the container. When I hit start, a red error icon appears next to the server and the container.
When I go to the URL specified in the Container Info side panel, (http://192.168.1.11:8080/kie-server-6.2.0.Final-webc/services/rest/server/containers/test
) I get the following response XML
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<response type="SUCCESS" msg="Info for container test">
<kie-container container-id="test" status="FAILED">
<scanner status="DISPOSED"/>
</kie-container>
</response>
Is there a log file I can go to get more information? I am running kie-server and kie-workbench on Tomcat 7.
Maybe 'TOMCAT_HOME\logs\catalina.log' is what you're looking for? If you also want to see the log in terminal, you can modify 'TOMCAT_HOME\logs\startup.sh'. That is, changing
exec "$PRGDIR"/"$EXECUTABLE" start "$#"
into
exec "$PRGDIR"/"$EXECUTABLE" run "$#"
Though I can make some containers start up correctly, I'm still facing some problems, see this.
For your reference, I can see the following response on the link you provide when container started up correctly:
<response type="SUCCESS" msg="List of created containers">
<kie-containers>
<kie-container container-id="droolsTest" status="STARTED">
<release-id>
<artifact-id>droolsTestProj</artifact-id>
<group-id>demo</group-id>
<version>2.0</version>
</release-id>
<resolved-release-id>
<artifact-id>droolsTestProj</artifact-id>
<group-id>demo</group-id>
<version>2.0</version>
</resolved-release-id>
<scanner status="DISPOSED"/>
</kie-container>
</kie-containers>
</response>
I am following these exercises for learning Liberty.
I am having an issue in he Lab 3 - Module 2.2 Liberty and JPA (DB2) .
After setting all the JDBC and Data Source details, i restart the server and i do not see the two lines that mention the dataSource and jdbd driver.
[AUDIT] J2CA8004I : The dataSource DB2Connection is avilable as jdbc/DB2Connection.
[AUDIT] J2CA8000I : The jdbcDriver my JDBCDriver is available.
How can i know if the jpa and jdb features ae correctly set?
This is the server.xml
<!-- Enable features -->
<featureManager onError="WARN">
<feature>jsp-2.2</feature>
<feature>jpa-2.0</feature>
<feature>jdbc-4.0</feature>
</featureManager>
<!-- To access this server from a remote client add a host attribute to the following element, e.g. host="*" -->
<httpEndpoint id="defaultHttpEndpoint"
httpPort="9080"
httpsPort="9443" />
<jdbcDriver id="myJDBCDriver">
<library name="DB2Lib">
<fileset dir="C:\wlp\db2jdbc" includes="db2jcc4.jar, db2jcc_license_cu.jar"></fileset>
</library>
</jdbcDriver>
<dataSource jndiName="jdbc/DB2Connection" id="DB2Connection"
jdbcDriverRef="myJDBCDriver">
<properties.db2.jcc databaseName="SAMPLE" serverName="igacloud" password="{xor}FhgeOz1tPj08" user="db2admin"></properties.db2.jcc>
</dataSource>
Unlike Classic WebSphere, which has a "test connection" capability in its admin console (datasource panel), there is no equivalent means with WebSphere Liberty yet. Have you tried testing the connection with a simple "Hello World" JPA application?
The CWWKF0012I message is simply confirming what features have been enabled - some features depend on other features and automatically enables them, which is why you see more features than defined in your server.xml.
I have a WebSphere Application Server V8.5 Liberty Profile in eclipse. My webapp has been giving java.lang.OutOfMemoryError and thus I need to increase the heap size.
As this and this post suggested I changed the server.xml, by adding jvmEntries tag (It was not previously there):
<server description="new server">
<!-- Enable features -->
<featureManager>
<feature>jsp-2.2</feature>
<feature>localConnector-1.0</feature>
<feature>jpa-2.0</feature>
</featureManager>
<!-- To access this server from a remote client add a host attribute to
the following element, e.g. host="*" -->
<httpEndpoint httpPort="9080" httpsPort="9443" id="defaultHttpEndpoint" />
<jvmEntries initialHeapSize="1024" maximumHeapSize="2048" />
<applicationMonitor updateTrigger="mbean" />
<webApplication id="app" location="app.war"
name="app" />
</server>
But eclipse shows it as an invalid tag, with following error:
cvc-complex-type.2.4.a: Invalid content was found starting with
element 'jvmEntries'. One of '{include, variable, trustAssociation,
applicationMonitor, application, classloading, basicRegistry,

quickStartSecurity, pluginConfiguration, webContainer, httpSession,
httpSessionDatabase, sslDefault, keyStore, ssl, sslOptions,

How should I increase the heap size then?
Correct way to do it is to create jvm.options file in the server directory with the following content e.g.:
-Xms512m
-Xmx1024m
Check this link Customizing the Liberty profile environment
In Eclipse, in the Servers view you can right-click the server, and select New > Server Environment File > jvm.options
The Liberty profile is a bit different than the regular WebSphere profile. You will need to configure a jvm.options file per these instructions:
IBM Setting generic JVM arguments in the WebSphere Application Server V8.5 Liberty profile

When I develop a WCF service or website solution, I always use IISExpress with a custom configuration file so I can share the setup with other developers in the team. Basically, I run a batch file with the following command in it:
"C:\Program Files (x86)\IIS Express\iisexpress.exe" /config:service-hosts.config
Where service-hosts.config is the path to my custom configuration file.
This method has been working perfectly fine, and still works fine in other solutions on my PC (each with their own service-hosts.config file). However, I've just started having a problem loading a WCF service using this method. I'm getting the following error when trying to browse to the service root dir, or any of the built in help endpoints:
HTTP Error 500.19 - Internal Server Error
The requested page cannot be accessed because the related configuration data for the page is invalid.
Detailed Error Information:

More Information:
This error occurs when there is a problem reading the configuration file for the Web server or Web application. In some cases, the event logs may contain more information about what caused this error.
If you see the text "There is a duplicate 'system.web.extensions/scripting/scriptResourceHandler' section defined", this error is because you are running a .NET Framework 3.5-based application in .NET Framework 4. If you are running WebMatrix, to resolve this problem, go to the Settings node to set the .NET Framework version to ".NET 2". You can also remove the extra sections from the web.config file.

I've been debugging for hours and can't get this error to change, let alone fix it.
I've tried overwriting my service-hosts.config file with a few different versions of applicationHosts.config, running IISExspress in 64bit, replacing the web.config file with a very basic version, setting permissions on the directory (to the point where every user on my PC has access), and changing the app pool, but still no change.
The weird thing is... when I change the WCF project to use "IISExpress" in the Web section of project properties, then subsequently debug the project, everything works fine... even with all of my web.config settings in place.
This points to how I'm running IISExpress, or my service-hosts.config file... though the service-hosts.config file (with slight modifications for the sites involved) is exactly the same as it is in my other projects.
One thing to note (might be a red herring), but I did downgrade the solution from VS2012 to VS2010, and changed the framework target to .Net 4.0... not sure if something might be configured funny due to that?
Does anyone have any ideas? I'm at the point of jumping off the roof...
UPDATE:
Here's the debug information from IISExpress (running with /trace:e):

Seems that the service-hosts.config file was pointing to something it shouldn't have been pointing to. I replaced my service-hosts.config with an copy from an older project (and therefore an older version of IISExpress / .Net Framework) and everything works fine.
Sounds like it was to do with my 4.5 -> 4.0 downgrade after all.
