Running multiple concurrent instances of maps
When you run multiple concurrent instances of maps, enable map caching and set unique work file names and audit file names for maps that perform I/O.
When multiple instances of a map are running in multiple services or multiple business processes, traces are recorded in the designated file for the first business process thread that runs, but other business processes and other threads fail to trace. The map does not fail or cause an exception.
For optimal performance,
configure the map settings to use unique work files and audit files
as follows:
- When the Map Settings enable map audit, set to File and set the audit FileName to Unique.
- In the Map Settings set WorkSpace to File and set WorkFilePrefix to Unique.
- When the Edit Input Card or Edit Output Card settings enable backup for a card, set to Unique. The map does not fail, and it does not throw an exception.
See the IBM Transformation Extender Map Designer documentation for more information about running multiple instances of a map.
