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:

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.
