Performs OCIThread process initialization.
Whether or not this function needs to be called depends on how OCI Thread is going to be used.
In a single-threaded application, calling this function is optional. If it is called at all, the first call to it must occur before calls to any other OCIThread functions. Subsequent calls can be made without restriction; they will not have any effect.
In a multi-threaded application, this function must be called. The first call to it must occur strictly before any other OCIThread calls; i.e., no other calls to OCIThread functions (including other calls to this one) can be concurrent with the first call.
Subsequent calls to this function can be made without restriction; they will not have any effect.
