websphere 升级JDK报错？
现有WAS版本为8.5.5.13，默认JDK1.6，由于开发应用需要想升级到JDK1.8，在升级的过程启动概要文件./managesdk.sh -enableProfileAll -sdkName 1.8_64时报如下错误：意外异常 com.ibm.websphere.management.exception.AdminException: com.ibm.websphere.management.exception.AdminException: CWLCA0012E: SDK 1.8_64 在节点 web4Node01 上不可用 ；不知道什么原因，请大神指教，感谢。

First make sure the desired SDK is installed and can be listed with the managesdk command:
$ ./managesdk.sh -listAvailable
CWSDK1003I: Available SDKs :
CWSDK1005I: SDK name: 1.7.1_64
CWSDK1005I: SDK name: 1.6_64
CWSDK1001I: Successfully performed the requested managesdk task.
If it is listed then these errors can occur if nodeagent on the listed node (jurecek1Node01) is not running. If the nodeagent is not running, please start it with the startNode command and check the systemOut.log file to ensure you see the "Open for e-business" line. Then run the managesdk command again which should now complete without error.
You should see output similar to the following if it is successful:
$ ./managesdk.sh -enableProfileAll -sdkname 1.7.1_64 -enableServers
CWSDK1024I: The node default SDK setting for federated profile
AppSrv03 has been saved in the master configuration repository.
CWSDK1025I: A synchronization operation is required before
configuration changes to federated profile AppSrv03 can be used.
CWSDK1017I: Profile AppSrv03 now enabled to use SDK 1.7.1_64.
CWSDK1001I: Successfully performed the requested managesdk task.
