By default, Enterprise Server does not create a core dump for run-time errors. To configure an Enterprise Server region to produce a core dump for run-time errors: 
	 
 
	  
		- Create a run-time tunable text file, for example COBCONFIG.CORE.TXT with the following entries: 
		  SET CORE_ON_ERROR=131
SET CORE_FILENAME="core.%p@%t_%d" 
- Access the Enterprise Server Administration screen, and in the Status column, click the 
		  Details button for the 
		  Enterprise Server instance. 
		
- To add the configuration to 
		  Enterprise Server instance, add the entry to your Enterprise Server region configuration. When you start the region, core dumps will be produced by run-time errors. See the illustration below for an example.
