The pictures which are displayed within the URL preview of the Activity Stream are saved in the Homepage database. Unfortunately they will be stored using the absolute path to the file inside the Connections shared directory. For example ‘/mnt/cnxShared/common/urlPreview/shared/00000000-0000-0000-0000-000000000000/3e5ecb33-6d18-44b0-8e29-1d86f0ce26cc’.
If you change your mount point or UNC path the pictures will not be displayed anymore after your side-by-side migration is finished.
Following error message will be displayed in the log file:
[6/21/16 8:10:46:179 CEST] 0000015e ThumbnailServ W com.ibm.lconn.thumbnail.service.impl.ThumbnailService getThumnail CLFWY0621E: Exception occured whilst retrieving thumbnail from fileStore, ignoring. com.ibm.lconn.thumbnail.messages.ThumbnailRuntimeException: java.io.FileNotFoundException: /mnt/cnxShared/common/urlPreview/shared/00000000-0000-0000-0000-000000000000/3e5ecb33-6d18-44b0-8e29-1d86f0ce26cc (No such file or directory)
To fix this issue you need to change the file paths inside the databases. They are stored in the ‘FILE_PATH’ column within the ‘HOMEPAGE.IMG_CACHE’ table.
Changing database content is not supported by IBM!
