A quick look at maporaclespatial.c reveals the following global variables: /* local status */ static int last_oci_call_ms_status = MS_FAILURE; static text last_oci_call_ms_error[2048] = "";
therefore I think we can mark Oracle spatial support not thread safe. Most importantly to use the OCI libraries in multithreaded environments one *must* explicitly request the multi-threading features by passing a special flag to the OCI init functions.
