Based on the error you have shown, it seems that it is just encountering an error while trying to execute a **chmod** command to one of the file **install_Pool.sh**. Upon the first look, it could be a directory typo when executing the command,
I would suggest checking if Applicationa is the valid directory to point to, else to correct it and execute this **chmod** command again.
Otherwise, your installation should be correct and you should be able to start the VDP server with the <DENODO>/bin/vqlserver_startup.sh script.
Hope this helps!
