APAR status

• Closed as program error.

Error description

• If 2 users upload 2 files with the same filename but different
  content, into 2 CQ records on CQWeb, at almost the same time, it
  may cause problem.
  
  This is because the uploaded file will be firstly placed at the
  same staging location:
  <CQ_Install_Dir>\cqweb\cqwebprofile\temp\dfltNode\server1\TeamEA
  R\cqweb.war
  
  So the first file will be overwritten by the 2nd one.
  
  When the 2 users save the record, the 1st user will succeed, but
  the saved file could be wrong.
  
  And the file will be removed from the staging folder. So when
  the 2nd user does the save, he will see error:
  
  CRMUD0078E
  <CQ_Install_Dir>\cqweb\cqwebprofile\temp\dfltNode\server1\TeamEA
  R\cqweb.war\<filename> does not exist.
  Details:
  CRVAP0075E After completion of the 'ServerDeliverChangeContext'
  operation, not all resources were delivered as requested.
  CRVSV0187E
  Record has invalid field values. CRVAP0290E CRMUD0078E
  <CQ_Install_Dir>\cqweb\cqwebprofile\temp\dfltNode\server1\TeamEA
  R\cqweb.war\<filename> does not exist.
  
  If the 2 users happen to do the save at exactly the same time,
  they may both succeed. But in one record, the file is wrong.
  

Local fix

• This issue will rarely happen. Workaround is just to save the
  correct file again into the record. But it might be hard for
  user to notice the wrong file was saved.

  * PROBLEM DESCRIPTION:                                         *
  * If separate ClearQuest Web users concurrently upload a file  *
  * with the same filename but different content into separate   *
  * CQ records, the wrong file may be saved into the database.   *

Problem conclusion

• A fix is available in ClearQuest 8.0.0.17 and 8.0.1.10.
  Concurrent ClearQuest Web file uploads from different records
  with the same filename now always saves the correct file into
  the database.
  

Temporary fix
