I have been to numerous forums and cannot seem to find an up to date answer. I know I have to run some sort of command. I am on Windows 7 so what is the command I am supposed to run to fix this and can I run this command in the Windows command prompt.
回答1:
This exception is sometimes caused by corrupt serverindex.xml or server.xml files. Check for any of them that may be 0 bytes and restore from backup. If you don't have a backup creating a new profile will restore them.
回答2:
If you find the serverindex.xml is having some size for it, check if the serverindex.xml file is corrupted by opening it using Notepad ++ or similar tool. The file you need to refer is: \config\cells\Node01Cell\nodes\Node01.
If there are no backups, it is possible to use one of the temp file from \wstemp\anonymous1493784328013\workspace\cells\Node01Cell\nodes\Node01
Hope it helps anyone having similar issues.
