Multithreaded and multiple-context applications in Db2 ODBC
Db2 ODBC supports
multi-threading and multiple contexts. You need to follow certain
guidelines when using multiple contexts and multi-threading together
in an application.
Db2 ODBC support for multiple Language Environment threads Db2 ODBC application, it begins with an initial Language Environment thread, or parent thread. When to use multiple Language Environment threads Db2 ODBC support of multiple contexts context is the Db2 ODBC equivalent of a Db2 thread. Contexts are the structures that describe the logical connections that an application makes to data sources and the internal Db2 ODBC connection information that allows applications to direct operations to a data source.External contexts Db2 ODBC driver manages contexts in an ODBC application. With external contexts, you can write applications that manage contexts outside of Db2 ODBC. You use external contexts in combination with Language Environment threads in the same way you use multiple contexts in combination with Language Environment threads.Application deadlocks
