If this connection attribute is not set there is no timeout, which means the driver gets stuck waiting for a reply when a network issue happens.Īs of the writing of this document, the IBM i ODBC driver behavior when setting the SQL_ATTR_QUERY_TIMEOUT connection attribute is similar to the one described in ODBC Query Timeout Property. One fundamental connection attribute is SQL_ATTR_QUERY_TIMEOUT (and related _TIMEOUT attributes), which set the timeout for SQL queries done through the driver (or the timeout for other connection steps for other _TIMEOUT attributes). ODBC drivers can optionally support custom configuration through connection attributes, which help configure how a connection works. Limitations in the IBM i ODBC driver make it necessary to structure the check in a more complex way than would be expected, to avoid the check from hanging or leaking threads. To do so, it uses the ODBC Driver for IBM i Access Client Solutions, an IBM propietary ODBC driver that manages connections to IBM i hosts. The IBM i integration uses ODBC to connect to IBM i hosts and query system data through an SQL interface. ![]() ![]() This section is meant for developers that want to understand the working of the IBM i integration.
