▼ To Modify the RFID Information Server
Database Schema File
1. Save a copy of EpcisDbSchema.xml in a permanent location.
2. Modify the file to add or delete extended attributes.
3. Copy the modified file to the document root of the application server.
4. Restart the application server.
Caution – The EpcisDbSchema.xml file is intended to be modified once at
deployment. If changes are made to the file after the database has been populated,
the result might be inconsistent data in the database.
