Producing a core dump for run-time errors

By default, Enterprise Server does not create a core dump for run-time errors. For example, by default, if the operating system detects a memory access violation caused by your application, no core dump is produced. You must configure the system to produce a core dump for these situations.

Once you have produced a core dump, you can debug the core dump to help determine the cause of the error.

Note:

This functionality is available for the Windows and AIX operating systems only.
The functionality does not identify memory corruption issues. You can use it to identify application problems only.

To configure the system so that it creates a core dump for run-time errors, you need to create a run-time tunable configuration file, and add the tunable configuration file's details to your Enterprise Server region.

To create a run-time tunable file, create a text file, for example COBCONFIG.CORE.TXT with the following entries:
```
SET CORE_ON_ERROR=131
SET CORE_FILENAME="core.%p@%t_%d"
```
To add the configuration to Enterprise Server, 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.
