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,
bundleRepository, osgiApplication, authentication, authCache,

managedExecutorService, connectionManager, contextService,
distributedMap, enterpriseApplication, webApplication, httpDispatcher,
mimeTypes, httpEncoding, virtualHost, httpOptions,
httpAccessLogging, httpEndpoint, authData, dataSource, jdbcDriver,
jndiEntry, jpa, jspEngine, fileset, executor, featureManager, config,
customLdapFilterProperties, edirectoryLdapFilterProperties,

quickStartSecurity, pluginConfiguration, webContainer, httpSession,
httpSessionDatabase, sslDefault, keyStore, ssl, sslOptions,
timedOperation, transaction, webAppSecurity, federatedRepository,
zosLogging, authorization-roles}' is expected.
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:

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)

Workbench 7.0+ is not support Tomcat any more. If you want to use Workbench (it is already renamed to Business Central and has latest version 7.24) it should run on Wildfly 14.
You can try this quick start (just unzip file and it is ready to try or copy configurations): https://www.jbpm.org/learn/gettingStarted.html
If you need to start Workbench on Tomcat, you should use 6.x (which is not supported any more).
I have added system-properties tag in standalone-full.xml, but its not working in standalone mode. However, if I add the same tag in domain.xml it's working for domain mode.
<?xml version='1.0' encoding='UTF-8'?>
<server xmlns="urn:jboss:domain:2.2">
<extensions>
....
</extensions>
<system-properties>
<property name="java.util.Arrays.useLegacyMergeSort" value="true"/>
</system-properties>
</server>
According to this article on jBoss General configuration concepts
System property values can be set in a number of places in domain.xml, host.xml and standalone.xml.
Then what about standalone-full.xml?
I don't want to set it through command line and not even in java code.
In standalone it's probably too late to set it in the configuration files. You'll need to add it to the standalone.conf or standalone.conf.bat in the JAVA_OPTS environment variable. A global property like that needs to be set before anything else attempts to use java.util.Arrays.
If you have started the Wildfly server with standalone-full.xml instead of standalone.xml(the default) than this should be reflected in the start of the server:
standalone.sh -b <hostIP> -c standalone-full.xml -Dorg...
Then this will have effect on first start.
If you change something in this config file, you will need to reload Wildfly(configuration) from jboss cli:
[standalone#localhost:9990 /] :reload
For Wildfly 10 it's working nontheless. I was able to read the property for an instance started with the standalone-full.xml containing some properties.
The manual must be outdated then I guess? Because even Wildfly itself inserts a new property in the standalone-full.xml when using the Wildfly admin webinterface: http://localhost:9990 > Configuration > System Properties (Wildfly will add the property of course to the xml config which was used to start the instance). That's enough proof for me.
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.
Can I dump a properties file somewhere in one of the JBoss 6 directories, and pick it up from the classpath?
Or even better, does anybody know the mechanism behind a configuration file like $JBOSS_HOME/server/default/deploy/jboss-logging.xml? Changes to this file seem to trigger an event, so that a running instance can process the modifications (without having to bounce the AS).
A possibility is to configure SystemPropertiesService in ./conf/jboss-service.xml.
This allows you to configure system properties in-place, or load them from a properties file:
<server>
<mbean code="org.jboss.varia.property.SystemPropertiesService"
name="jboss.util:type=Service,name=SystemProperties">
<!-- Load properties from each of the given comma seperated URLs -->
<attribute name="URLList">
http://somehost/some-location.properties,
./conf/somelocal.properties
</attribute>
<!-- Set propertuies using the properties file style. -->
<attribute name="Properties">
property1=This is the value of my property
property2=This is the value of my other property
</attribute>
</mbean>
</server>
For more details, refer to: http://docs.jboss.org/jbossas/admindevel326/html/ch10.html
They have made this even easier in JBoss EAP 6 (AS 7).
Pass Property File as Startup Parameter
This can be added within the main start up script or passed as parameter
./standalone.sh --properties=/Users/john.galt/dev/config/ds/jboss.properties
If these properties are read, they will be rendered in the server log as the first statement.
3:58:41,633 DEBUG [org.jboss.as.config] (MSC service thread 1-6) Configured system properties:
DSsettings.password = password
DSsettings.user-name = admin
DSsettings.connection-url = jdbc:oracle:fat:#activedb:1521:DEV
[Standalone] =
awt.nativeDoubleBuffering = true
NOTE: As these settings are logged in server log, ensure no clear text passwords are in the property files in production
Use passed in system properties
You could use these system properties with following syntax.
Example Usage in a data source file
<xa-datasource jndi-name="java:jboss/ds" pool-name="cPool" jta="true" enabled="true" use-ccm="true">
<xa-datasource-property name="URL">
${DSsettings.connection_url}
</xa-datasource-property>
<driver>oracle</driver>
...
<security>
<user-name>${DSsettings.user-name}</user-name>
<password>${DSsettings.password}</password>
</security>
...
</xa-datasource>
In JBoss 6 use: ./deploy/properties-service.xml
On JBoss AS7 properties-service.xml no longer exist, the below is the solution:
