Multithreading Support v12

Suggest edits

OCL is supported in multithreaded environment. You can enable/use multithreading in a multithreaded environment by making an OCIEnvNlsCreate() call with OCI_THREADED as the value of the mode parameter.

retCode = OCIEnvNlsCreate( &envp,
                           OCI_THREADED,
                           NULL,
                           NULL,
                           NULL,
                           NULL,
                           0,
                           NULL,
                           0,
                           0 );

All subsequent calls to OCIEnvNlsCreate() must also be made with OCI_THREADED.

OCI library manages mutexes for the application for each environment handle if a multithreaded application is running on a thread-safe operating system.
