This tool is being developed to solve a very common problem of “missing files in store/Location”. File Reconciliation tool generate excel file report which contains the list of files from object meta-data information (information as in database) and gives a status of file availability on relevant locations/store folder path. This scenario happens when files from locations/store folder path is being deleted for various reasons but object still have the information that file exists.
When user tries to download file from 3DEXPERIENCE, he gets message either of below error messages.
A common reason for such scenario to happen is because of your STORE/Location definition and open access to the host machine which is hosting your files. Your STORE or Location definition has host as IP address or machine name. This information is stored in your database.
Typically administrator creates copy of the Production system in 2 ways to make test/QA/Dev system:
And user thinks they are completely independent and disconnected from Production system.
But No. you are NOT. Your copy VM/Database still has exactly same STORE/Location definition as your production system. It still points to same host and file path of production.
So, when you delete the object from your copy VM/Database, you end up deleting object meta data from your copy VM/database but that object has still file reference to your production system. So, along with object, file will also be deleted for sure.
Your production object still does have the file as meta data from oracle database but it does not know that it’s file from store/location is lost..!!!
There is no straight single command to identify objects whose files are missing from your location/store folder path. Also complexity of problem increases when you have FCS configured. When FCS exists, you may have file lost from one FCS and it exists in STORE or other FCS location. In this case also, user will end up getting the error when he tries to get file from his closest FCS where file has been deleted. Because 3DEXPERIENCE does not synch the file again because as per its record, file is already synched and exist.
So, thorough understanding of master file, synchronized file and synchronization status is required to programmatically find which all files are missing. Also, when you have multiple files checked in to same object/format; report becomes more complex.
File Reconciliation tool generates this complex report of missing files with all possible scenario.
Following is sample report
Type – type of an object which contains file attached to an object
Name – name of an object which contains file attached to an object
Revision – revision of an object which contains file attached to an object
Created Date – created date of an object which contains file attached to an object
Modified Date – last modified date of an object
Originated By – creator of object
Format – format of the file attached to an object
File Name – name of the file attached to an object
File Modified Date – last modified date of the file attached to an object
Location Name – synchronized location/store of the file attached to an object
File Host IP – IP address of host machine of location/store of the file
Physical Path – physical directory path of location/store of the file
Complete Path (absolute path) – complete physical path generated from path mentioned on location/store + “Physical Path”
File Exists? – If file exists on Complete Path (absolute path): TRUE, otherwise: FALSE
File Exist in Peer Location – TRUE if file does not exist in current location but it exists in peer location. So, there is possibility to restore file with sync command.
Sync Command: MQL command to force synchronize(copy) file from peer location to current location
Restore files once you have report of missing files
There is no full proof way unless you have File store backup. But following are the options.
