HD56755: PRODUCT STRUCTURE / OPENING THE PRODUCT TAKES LONGER ON R14

APAR status

• Closed as program error.

Error description

• Scenario:
  1. Launch Catia
  2. Tools + Options + Product Structure + Product
  Visualization + check "Do not activate default
  shapes on open"
  3. File + Open: MFNX-MC01-S11-12-PREFER-
  01.CATProduct
  ==> performance = 27 minutes : too much
  .

Local fix

Problem summary

• Product Structure / Opening the Product takes longer on R16
  than R12 on a HP-UX machine.
  Scenario:
  1. Launch Catia
  2. Tools + Options + Product Structure + Product
  Visualization + check "Do not activate default
  shapes on open"
  3. File + Open: MFNX-MC01-S11-12-PREFER-
  01.CATProduct
  ==> performance = 27 minutes : too much
  .
  .
  

Problem conclusion

• THIS PROBLEM WILL BE FIXED ON CATIA VERSION
  5 RELEASE 18 GA level.
  NOTE THAT THIS PROBLEM WILL ALSO BE FIXED
  ON V5R16SP08 and V5R17SP02.
  .
  Incident Diagnosis :
  Product Structure : opening the Product takes too
  long when opening in Assembly Design workbench
  on HP. This performance problem is due to the
  updatestatus computation (as there is no update
  icon to manage in Product Structure workbench,
  this explains the difference between Assembly and
  Product Structure).
  .
  During the update status computation a service
  'CATAsmGetPrdRefInAsmTree' is called to get the
  list of all reference products in the assembly
  (this list is browsed and exploited afterwards).
  To insure that each Reference is only added once
  in the list, a Locate is performed and the
  reference is added only if it is not found.
  .
  The complexity of such an algorithm is O(n*n/4);
  in the customer data there are 25941 different
  reference products: n=25941...
  .
  Correction Explanation :
  the algorithm is modified : instead of using a
  CATLISTV(CATBaseUnknown) + Locate, a
  Hashtable + Insert is used.
  .
  The complexity of the new algorithm is O(n), and
  the result is a lot better now.
  .
  To spare one list scan, we integrate the
  algorithm content directly in its caller.
  .
  Answer and By-Pass
  Improvements have been provided in HP on these
  levels : the performance has been decreased in -
  39%.
  .
