# tibems_setExceptionOnFTSwitch

Function

## Purpose

        tibems_bool callExceptionListener);

## COBOL Call

    CALL "tibems_setExceptionOnFTSwitch"
      USING BY VALUE callExceptionListener,
      RETURNING tibems-status
    END-CALL.

## Remarks

This setting determines exception behavior when the client successfully switches to a different server (fault-tolerant failover).

## Parameters

Parameter | Description
--- | ---
`callExceptionListener` | When true, the connection’s `ExceptionListener` catches an exception, which contains the name of the new server. When false, fault-tolerant failover does not trigger an exception in the client.
