禁用 Portal 管理控制台层次树 (tree)

问题描述
将外部 LDAP 身份验证程序与 WLP 8.1 一起使用，可能会致使再现 Portal 管理控制台中的层次树 (tree) 时的响应速度减慢。响应速度缓慢常常会引起性能问题，还可能在用户/组功能不再起作用的地方导致异常被抛出。当存在大量的用户和/或组时，通常会出现此种问题。

为什么发生此问题？
发生此问题的原因是：因单击 Portal 管理控制台中的任何用户/组功能，而导致对整个 LDAP 服务器内容进行搜索。

返回页首

解决方法
有一个命令行系统属性可以禁用层次树 (tree) 的再现，从而避免此问题。默认情况下，会启用层次树 (tree) 再现。要禁用层次树 (tree) 再现，请设置下面的命令行系统属性，然后重新启动服务器：

-Dcom.bea.jsptools.disableGroupTree=true

备注：禁用组树 (tree) 将排除 Portal 管理控制台的一些组管理功能。如果禁用组树 (tree)，则必须使用 WLS 控制台或第三方工具（如 LDAP 服务器的管理控制台）才能实现下列功能：

* 创建/删除/移动组

对于只读的 Authentication Provider（如外部 LDAP Authentication Provider），在任何情况下都不能使用 WLS 或 Portal 工具执行这些功能。因此，在这种情况下，Portal 管理控制台并未丢失任何功能。

bea.jsptools.disableGroupTree 系统属性在 WLP 8.1 SP3 及版本更高的 Service Pack 中可用。如果需要在以前的 Service Pack 中使用此功能，则请与 BEA 客户支持部门联系，请其提供 CR126130 修补程序。该修补程序允许您设置 bea.jsptools.disableGroupTree 系统属性。

已知问题
您可定期查看您的版本的“发行说明”以获得有关 Service Pack 中的“已知问题”或“已解决的问题”的详细信息，而且还可浏览与层次结构树 (tree) 有关的问题。为方便起见，请参阅下列内容：

搜索还将返回“发行说明”，以及其它“支持解决方法”和与 CR 相关的信息（在需要更多帮助？中说明）。如果客户签订了技术支持合同，则可以登录 http://support.bea.com/，登录后会看到为 Solutions 和 Bug Central 提供的 Browse portlet，可在其中按产品版本浏览最新提供的 CR。

需要更多帮助？
如果您已经理解这个模式，但仍需要其它帮助，您可以：

在 http://support.bea.com/ 上查询 AskBEA（例如，使用“What can cause WLP 8.1 to have poor performance”），以发现其它已发布的解决办法。技术支持合同客户：确保已经登录，可以访问提供的与 CR 有关的信息。
在 http://forums.bea.com 上，向 BEA 的某个新闻组提出更详细具体的问题

如果这还不能解决您的问题，并且您拥有有效的技术支持合同，您可以通过登录以下网站来打开支持案例：http://support.bea.com/。
