If the Oracle Applications used database is having many messages in the AQ tables, DBUA fails with above error message. For some reason if you you add additional space to ODMA_RBS from the backend while DBUA is doing its job, the additional space that is added is not recognized.

Workaround :

So, workaround is to edit the file $ORACLE_HOME/assistants/dbma/mep.cfg and make changes to the following XMLtags before you kick off the DBUA.

InNewTablespace name="ODMA_RBS" size="50" unit="MB"

Change the size to the size you desire and then launch DBUA. It should solve your problem.

Enjoy !!
