PM45585: The data model for an EJB v2.1 CMP mapping may contain double synonyms when it is migrated to version 7.5.5.4

Rational Application Developer for WebSphere Software, Version 7.5.5.5

APAR status

• Closed as program error.

Error description

• An EJB CMP mapping and data model may fail with a
  NonUniqueNameException when it is migrated to Rational
  Application Developer v7.5.5.4 and result in double synonyms
  defined in the data model file.
  
  Problem Details:
  
  An EJB CMP mapping and data model may fail with a
  NonUniqueNameException when it is migrated to Rational
  Application Developer v7.5.5.4.
  
  The migration wizard completed successfully; However, the
  workspace .log file shows an error for every column in table;
  For example:
  
  !ENTRY com.ibm.etools.ejbdeploy.core 4 0 2011-06-09 12:47:56.548
  !MESSAGE Backend migration failed on href
  'META-INF/backends/ORACLE_V10_1/sample.tblxmi#PERSON_NAME' in
  project 'MyTestProject'
  !STACK 0

  com.ibm.datatools.migration.resource.ResourceHelper.getEObjectID
  (Unknown
  Source)
  ...
  
  In the migrated project the resulting data model file (dbm) has
  2 copies of the original table.  Naturally the EJB mapping to
  this is also bad as it shows two synonyms and no mapping.

  ****************************************************************
  While migrating the EJB projects from Rational Application
  Developer v6 models to Rational Application Developer
  v7.5.5.4 models, two synonyms are created in the v7 version
  even if there was only one synonym in v6. These new synonyms
  are actually duplicates of each other.
  
  The functionality will be correct if the migration results
  only in one synonym in v7 models.
  

Problem conclusion

• The code was updated and this problem is fixed in Rational
  Application Developer v7.5.5.5.
  

Temporary fix
