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, jaasLoginModule, jaasLoginContextEntry, cdiContainer, channelfw, tcpOptions, library, collectiveMember, hostAuthInfo, 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, domino50LdapFilterProperties, netscapeLdapFilterProperties, ldapRegistry, securewayLdapFilterProperties, iplanetLdapFilterProperties, idsLdapFilterProperties, activedLdapFilterProperties, logging, ltpa, ejbContainer, monitor, oauthProvider, oauth-roles, remoteFileAccess, administrator-role,
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?
