Migration from 10g to 12c using data pump hi there, while I've used data pump at the schema level before, I'm rather new at full database imports. I am trying to develop a script that will dynamically build RMAN scripts for backing up a database with read-only tablespaces. The application running on this database creates new tablespaces in read-write mode on weekly basis, populates them, and then puts them in read-only mode.
Migration error messages You can take corrective actions in response to error messages that occur while you use the Migration Manager application.
The following list of messages is not comprehensive but it contains the messages that you are most likely to encounter. Check the associated stack trace to determine the cause of the error.
The stack trace provides more details. Depending on the cause of the error, you can try to distribute the package again. Depending on the cause of the error, you might have to remove records manually.
No root folder has been configured for the mxe. If no root folder is configured, the Migration Manager application file operations are performed on the home folder of the application server.

BMXAAE Could not get database name in source environment The name of the source database cannot be retrieved from the database to generate the source information for a package definition.
You might have to work with a database administrator to correct the error. BMXAAE Could not get database schema name in source environment The schema name of the source database cannot be retrieved from the database to generate the source information for a package definition.
The error is recorded in the log file if the logger is configured. The associated stack trace indicates the cause of the error. BMXAAE Could not register event listeners for all active Migration Manager change packages The application cannot register the event listeners for the active change packages.
The error might occur when the application server starts. The package file contents might be corrupted. You can test the file by copying it and extracting the manifest from the copy. If you cannot extract the manifest, re-create or redistribute the package.
If the package file is not corrupted or if the manifest can be extracted, review the associated stack trace to identify the cause of the error.
BMXAAE Error in checking entry in dmrestriction table The application cannot check the restriction entries in the target database environment when distributing a package.
Depending on the cause of the error, you can try the redistribution again. Check if you have write permissions in the parent folder and if there is enough disk space. Check with the target environment database administrator for database availability and the required connection parameters and update the target definition.
The cause of the error might be a database issue related to table spaces or permissions. Check the write permissions on the folder and check for enough disk space. Alternatively, obtain a new package from the source and deploy the new package.RESTART DATABASE with the WRITE RESUME option will only perform crash recovery when you use it after a database crash.
The WRITE RESUME parameter can only be applied to the primary database, not to mirrored databases. Could also be that The database file is not supported by the MigrationAssembly. The same exception is thrown when the EF tries to migrate on a file expected to be a SQLite database which is fi.
