How to Lower Heap Size of WebSphere Server
提问by Connection
I tried to change the Heap Size of my local WebSphere Server instance to 2G using the "Run Administrative Console" function in RAD but apparently, that was too big of a number. Now, I can't start the server anymore and I get this error:
我尝试使用 RAD 中的“运行管理控制台”功能将本地 WebSphere Server 实例的堆大小更改为 2G，但显然，这个数字太大了。现在，我无法再启动服务器并收到此错误：
JVMJ9VM015W Initialization error for library j9gc23(2): Failed to instantiate heap. 2G requested
Could not create the Java virtual machine.
I can't just change it back to a lower number because I can't seem to use the "Run Admin Console" function without starting the server first so I was wondering if anyone knew where the config file is kept for this? How can fix this problem?
我不能把它改回一个较低的数字，因为我似乎无法在不先启动服务器的情况下使用“运行管理控制台”功能，所以我想知道是否有人知道配置文件保存在哪里？如何解决这个问题？

Work with the server.xml under the config/cells/cellName/nodes/nodename/servers/servername/ directory.
使用 config/cells/ cellName/nodes/ nodename/servers/ servername/ 目录下的 server.xml 。
cellName and nodename would likley be based on your host name. I have kept them as cellName (and nodename) here in the structure above.
cellName 和 nodename 可能基于您的主机名。我在上面的结构中将它们保留为 cellName（和 nodename）。
The servername would be the default server1
服务器名将是默认的 server1
Look towards the bottom of the file
看向文件底部
It would have something like this: (Change the initialHeapSize and maximumHeapSize)
它会是这样的：（更改initialHeapSize 和maximumHeapSize）
Save the file and start your server and you should be able wot work with the server.
保存文件并启动您的服务器，您应该可以使用该服务器。
