Migrating Server Data from One Machine to Another

JReport Server resources such as catalogs, reports, users, security, scheduling, etc. can be migrated from one computer to another by simply Backing up and Restoring the Server Database.

To migrate JReport Server from the development environment on computer A to the production environment on computer B, you need to back up the server database data on computer A, move the backup files to computer B, and then restore the backup data to the server on computer B. You cannot migrate from one platform to another, for examples Windows to Linux or Linux to Windows.

The following example is based on Windows: 

1. Back up the server database data including system, realm and profiling databases on computer A. Choose either of the following methods:
   • Use DBMaintain.bat under <server_install_root>\bin on computer A. In a DOS window, switch to the <server_install_root>\bin folder and run the following commands:

     DBMaintain -Bsystemtables:C:\temp\systemtables.dat -Brealmtables:C:\temp\realmtables.dat -Bprofiling:C:\temp\profiling.dat

   • Admin users can back up data on the JReport Administration page.

     Backing up the system database: on the JReport Administration page, click Data > System DB on the system toolbar. Then go to the Backup tab, specify a file location and click the Backup button.

     Backing up the realm database: on the JReport Administration page, click Data > Realm DB. Then go to the Backup tab, specify a file location, check With External Data, then click the Backup button. In order to make resources usable you must backup the files with external data. If With External Data is unchecked, your resources will be visible in the server resource tree of the new server but none of the physical files will be in the history folder of the new server so they will fail with file not found errors.

     Backing up the profiling database: on the JReport Administration page, click Data > Profiling DB. Then go to the Backup tab, specify a file location and click the Backup button. Normally it would not be necessary to backup and restore the profiling database as it only contains records about reports run on the current server, which may not be useful on the new server.

2. Install JReport Server on computer B and then configure the server database. Note that the server databases on both computer A and B must be different. For example, when computer A uses MySQL database f, then computer B cannot use database f unless they are on different servers.
3. Copy the files created in the step 1 from computer A to the D disk on computer B:

   D:\systemtables.dat
   D:\realmtables.dat
   D:\profiling.dat

4. Restore the server database data using DBMaintain.bat in <server_install_root>\bin on computer B. In a DOS window switch to the <server_install_root>\bin folder, and then run the following commands:

   DBMaintain -Rrealmtables:D:\realmtables.dat -Rprofiling:D:\profiling.dat -Rsystemtables:D:\systemtables.dat

5. Start the server on computer B. The migration will be completed.
