如何在 Eclipse 中增加 WebSphere Application Server V8.5 Liberty Profile 的堆大小？

Question

我在 eclipse 中有一个 WebSphere Application Server V8.5 Liberty Profile。我的网络应用程序一直在提供 java.lang.OutOfMemoryError，因此我需要增加堆大小。

根据 this and this post 的建议，我更改了 server.xml，添加了 jvmEntries 标签（之前没有）：

<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>

但 eclipse 将其显示为无效标签，并出现以下错误：

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.

那我应该如何增加堆大小？

Answer 1

正确的做法是在服务器目录中创建 jvm.options 文件，内容如下：

-Xms512m
-Xmx1024m

勾选这个linkCustomizing the Liberty profile environment

在 Eclipse 中，您可以在 Servers 视图中右键单击服务器，然后 select New > Server Environment File > jvm.options

Answer 2

Liberty 配置文件与常规的 WebSphere 配置文件略有不同。您需要按照以下说明配置 jvm.options 文件：

IBM Setting generic JVM arguments in the WebSphere Application Server V8.5 Liberty profile
