How to convert Controller client application to run using LAA ("Large Address Aware") enabled

Troubleshooting


Problem

Customer is experiencing intermittent "OutOfMemoryException" errors on a client device which is based on a 64-bit operating system, and has more than 2Gb RAM installed. How can the Controller client be modified to allow it to use more than 2Gb RAM (typically the full 4Gb potential that is physically allowed)?

Symptom

There are many potential "OutOfMemoryException" errors that are listed in the IBM Technotes.

  • For example "System.OutOfMemoryException: Out of memory" when exporting structures
    • For more information see separate IBM Technote #1402263.

Alternatively, the end users may find that they receive a strange 'red cross' background to Controller from time to time.
  • For more information see separate IBM Technote #1585672.
