Reverting Back to Old-Style Tracing and Logging: Set DIAG_ADR_ENABLED=off in the following locations, after doing so, set a trace_level accordingly:

revert to client/server tracing/logging: set parameter DIAG_ADR_ENABLED=off in the client or server sqlnet.ora files

revert to listener tracing/logging: set parameter DIAG_ADR_ENABLED_listenerName=off in the listener.ora file

revert to cman tracing/logging:
Linux and Windows: add (DIAG_ADR_ENABLED=off) inside the parameter_list
