Create Task Branch

...

You can force Trafodion to abort and core dump on a specific error. Use this method.

• edit ms.env file (before running sqlci)

...

:

• 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.

• If you want to catch errors on all nodes of the cluster, copy the edited file to all nodes of the cluster:

  Code Block
  pdsh $MY_NODES $MY_SQROOT/etc/ms.env $MY_SQROOT/etc

  
  

• If you want to catch errors in the sqlci program, export this environment variable, then run sqlci:

  Code Block
  language bash
  export ABORT_ON_ERROR=<error-number> sqlci

  
  

win.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.
