IBM InfoSphere Information Server, Version 8.7 Fix Pack 1
IBM InfoSphere Information Server, Version 8.5 Fix Pack 3

APAR status

• Closed as program error.

Error description

• Import failure with istool occurs with the exception
  RepositoryImportException:
  java.util.ConcurrentModificationException
       at
  org.eclipse.emf.common.util.BasicEList$EIterator.checkModCount(B
  asicEList.java:1327)

  .java:1281)
  
  
  The problem will happen if there is linkpoint and also a real
  object with the same identity in the repository.
  For example,  in the repository there is:
  linkpoint for DSColumnDefinition with RID
  =>ad3d7bd0.87fd1fb9.8pdj36g34.03flar2.d01mg0.rd68nunb83g7mb5nup3
  sg
  and also a real object with
  RID=>c2e76d84.23d97ff8.8pdj3dqmi.1cojp2f.4l22ah.6j79fdacg9k6eu35
  mkdk8
  
  Generally this should not happen. The only chance of it happens
  is when both ISX and DSX imports are done.
  

Local fix

Problem summary

• Import fails with ISTOOL when both ISX and DSX imports are done.
  

Problem conclusion

• This problem happens when datastage jobs are imported using both
  ISX and DSX leading to situation where repository has both real
  object and corresponding linkpoint object.
   When anohter ISX import is done with this linkpoint object, it
  merges with repository real object, marks the repository
  linkpoint object for deletion but then attempts to update
   it downstream leading to this error.
  
   Order of import leading to this error: ISX --> DSX --> ISX
  
   There are two errors that were fixed:
