Embedded SQL and RPG time out - montioring

Is there a way in RPG with SQL to place a timeout on an sql statement.
We are using SQL to interface with Vertex and we hit an issue where the request to vertex never returned with a response. There was no error, the exec sql just sat there:

// Send request & receive response. Move response into responseText
exec sql
values qsys2.HTTP_POST (trim(:url), :requestText)
into :responseText;

Is there a way to force the SQL to error out or time out?
Is there a way to force qsys2.HTTP_POST to timeout?


Thanks for any help.
