Force Core Dump on Specific SQL Error
You can force Trafodion to abort and core dump on a specific error. Use this method:
If you want to catch errors in processes other than sqlci, edit the $MY_SQROOT/etc/ms.env file and add the following line
| Code Block |
|---|
ABORT_ON_ERROR=<error-number> |
There is only one error number that will take effect, so if you have two lines of ABORT_ON_ERROR, the last one wins.
This will help you to debug when a query run into a SQL error, and it is hard to figure out which code path it runs into. Note that the changes in ms.env will affect all processes on that node and therefore could disrupt operation of your cluster.
