Problem: 

 Access to shared document_library is needed on multiple UMP servers environment, but the access is denied.

 

 Here is an example when the problem occurred.

 

from portal.log in [wasp probe install directory]

28 6 2016 13:56:34,787 ERROR [ImageImpl:67] Error reading image 11303

Caused by: java.io.FileNotFoundException: C:\Program Files (x86)\Nimsoft\probes\service\data\document_library\0\0\11303.png\1.0 (Access is denied.) 

at java.io.FileInputStream.open(Native Method) 

at java.io.FileInputStream.<init>(Unknown Source) 

at com.liferay.portlet.documentlibrary.store.FileSystemStore.getFileAsStream(FileSystemStore.java:212)

 

Environment:  

 multiple UMP servers

 

Cause: 

 Local system account does not have access privilege to the shared document_library.

 

Workaround:

 1. Open [Administrative Tools] > [Services] console from Start menu.

 2. Open [Nimsoft Robot Watcher] properties dialog, then go to [Log On] tab.

 3. Set an account who has access privilege to the shared document_library and password for [Log on as] > [This account].

 4. Apply the change, then restart [Nimsoft Robot Watcher] service.

 5. After UMP (wasp probe) is restarted, access to the shared document_library will be allowed.
