Description :Impossible to start Dollar universe after a system crash / power failure.
Impossible to launch dollar universe command line.
Environment:
OS: All
Cause:
Cause type:
Other
Root Cause: The error "too many open files" probably led to the corruption of the files u_proxy.dta and u_fmsc60.dta
u_proxy.dta: file that contains the system user patterns, pushed from the uvms, and therefore the reason of the message "Access Denied" on every command launched from the system.
Resolution:
In order to fix the issue, a restore of the files u_proxy.dta / u_fmsc60.dta / u_fmsc60.idx from a previous backup is needed.
The procedure would be:
1. Stop the node
2. Backup the current files
3. Restore the files on the folder data: u_proxy.dta / u_fmsc60.dta / u_fmsc60.idx
4. Launch an offline reorganization
5. Start the node again and launch a full synchronization from the univiewer console.
